Groestlcoin 6th Anniversary Release
Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications. Ubuntu http://groestlcoin.org/forum/index.php?topic=441.0
ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
BTC Node. Need help with Ubuntu and BTC core program. To the Linux experts here in reddit.
The good thing of loosing a post, is that you have to retype everything and this means that you are able to shorten the post. So. TLDR, I have 2 hdd, 80gb and 320, the second one has only, all the Blockchain info, from another already running node. I am not able to tell BTC Core program that the files are already there so he does not need to download 300gb. After hours of Google and linux forums, I am stuck in this issue. Every time I type "bitcoin-qt" on my terminal, it shows as a first download. Any help will be appreciate. Full story. English is not my first language, and this is being typed for second time (please have mercy on my grammar or misspelling mistakes), because I posted the question on linux subreddit nobody give a f..... so I decided to bring it here, posted a short post with the link and the automatic bot deleted because the of the link. I erased both the linux and the bitcoin post, and made a third one new, here, with plain text, copy pasting the info from the linux post. Never appeared on the "new" section of this sub. So hours of typing lost, and here we are. Old Notebook. 80gb drive, and noob to Linux. Although I have some pc and logic knowledge, installed MINT due to a recommendation from a Bitcoin community, but since I have a friend with an already running node, with Ubuntu switched to this one, just to have the same system. Once Ubuntu installed, on the 80gb and pc running, I copy and pasted the whole bitcoin folder from my friends pc to my 320 gb. Up to here all was good. But here is the problem My friend, who does not understand nothing about linux, is owner of a company and has an IT guy who made everything for him, but would not be willing to help me a lot, (just to be good with his boss but right now it is not reachable for me), but when we where on my pc he told me that Linux is very sensitive to ports, in other words, a small usb change, will do a program to loose the path for the files. SO, instead of using the 320gb disk on USB i installed on this notebook second Hdd bay (its an old high end laptop with 2 sata connectors), he was able to set the program and everything went well for a couple of hours, Bitcoin Core program started synchronizing, downloading very little info. I needed to turn of the pc to move it, so closed the program (waited until bitcoin core program told me was safe to) and turn it off, then turn it on again, and the problem was there, bitcoin core program started trying to download the whole blockchain in the spare 2gb of the 320 gb disk. So what it seemed to happen is that even when the disk is installed on a sata bay from the motherboard, as I did not installed ubunutu with this disk connected it's route (adress?) is dinamyc and that is why BTC Core Program lost the files and does not recognize it. After hours of google, linux forums and "askubuntu" i was able to, mount the 320gb disk, first editing the fstab ( i followed the guide in "askubuntu.com/questions/125257/how-do-i-add-an-additional-hard-drive") by the way. Trying to use VIM editor was a pain, it is REALLY difficult to type something there, and save it without pressing a wrong key. I had to cancel and start over at least a dozen times (plus reading several guides), but still was not able to mount the disk (Actually after following the steps, the hdd (320) disappeared from the GUI). went back, erased, and the did the NANO steps, and I THINK that now the hard drive it is fixed (before, any change,when restarting the second hdd took some time to appear, now it seems that is mounted and to a fixed adress). Well, after mounting the hdd, I tryed to call the bitcoin-qt and the initial download page appear and again tries to download from the initial block. I searched over hours "file association in ubuntu", "program files path" etc etc and the only thing I found is how to set up the desired software to open a file. For you to understand my mess, when I did the "user:user" thing, I did not understand completely what I was doing, (yes I had to be in sudo) BUT i think I managed to did the correct thing as both hdd are shown in the Ubuntu GUI. Some additional data is Both hard drives are formated in Ext4 I have (I think that) a fstab.bak before any changes I knwo that linux users sometimes ask for details on the system, just tell me the commands and i can run them to stick any info needed. Thanks for the help in advance.
[IDEA] [PROPOSAL] Monero Debian (deb) packages / Debian package repository deb.getmonero.org (I can do)
I have the skills to implement this if wanted. Possible User Experience This is a proposal, i.e. not implemented yet. Instructions for users, simplified. How to install monero using apt-get Download the repository signing key. wget https://www.getmonero.org/monero.asc Add the signing key. sudo apt-key --keyring /etc/apt/trusted.gpg.d/monero.gpg add ~/monero.asc Add APT repository. echo "deb https://deb.getmonero.org buster main" | sudo tee /etc/apt/sources.list.d/monero.list Update your package lists. sudo apt-get update Install monero. sudo apt-get install monero A few technical implementation details I would simply grab the binaries provided by getmonero.org, download them, check software (gpg) signatures, put these into deb packages, add these to a repository, and upload the repository. What I would not do is creating the binaries during package creation. While this is nice to have, it doesn't help user experience and blocks the progress on reaching this goal. See next chapter. Why simply put the pre-build Monero binaries into a deb package? 1) After bitcoin existing for more than 10 years, being popular and being in Debian unstable (sid) it still never made its way into Debian testing, let alone stable. Reason being explained that a difference in underlying libraries (even just security fixes) during compilation may result in a network split. Binaries compiled during packaging on different versions of Linux distributions might have different libraries that might cause a network fork / chain split. References:
(Note: above website saying Tags: fixed-upstream is probably a mistake as discussion at bottom says.) 2) The github issue of packaging monero stalled. 3) By shipping the same binaries as provided by getmonero.org reduces the chances of introducing a backdoor. Many Options
By adding Monero to Whonix repository, a effort for creating a separate Monero repository could be saved. I.e. instead of deb https://deb.getmonero.org buster main users could do deb https://deb.whonix.org buster main. It's really just about the upload location. By providing DNS, even upload to Whonix server can offer https://deb.getmonero.org.
Either I create the build instructions and source code of this implementation (Debian package and repository creation) the long term maintenance of putting new binaries into updated packages or only create build instructions and source code and someone from Monero team could create the actual deb packages and deb repository.
gpg signed debs. Either gpg signed debs or an apt repository. Or both. Your choice.
I'd start with Debian and perhaps Ubuntu packages for 64bit. Perhaps also 32bit. Potentially I could also do packaging for Feodra based distributions.
Timeline Doable quickly. The electrum (bitcoin) AppImage was recently added to a Debian package (binaries-freedom) by me and is now easily installable in Whonix. Pre-installed in testers version of Whonix already. About Me I am the founder of Whonix, which I am maintaining at present for more than 7 years. Whonix (formerly TorBOX) is a Debian GNU/Linux–based security-focused Linux distribution. It aims to provide privacy, security and anonymity on the internet. You can see an overview of packages I am maintaining on my github profile. To proof that this forum account adrelanos corresponds the same person maintaining whonix.org, it is added here. Questions What happened to, what is the successor of the forum funding system?
This is getting awkward. Last night, 31st of March, 21:32 (GMT +1) 0.5602 BTC were transferred to "1FmMasfuEE6wtpzdWiVnDynfJ5tyyVbhP3". This was almost 100% what was stored in said wallet. I have full AV, there's 0 spy and/or malware on this computer. What the hell?!
yes, it was still running 0.8.6 apparently, don't know if this could have been an issue, and just updated it to 0.9 (latest)
A lot of user asked lately, how to run Reddcoin on the popular Raspberry Pi platform. Raspberry Pi is a cheap ARM computer (using junk leftover chips with 10 year lag in technology) but it has enough RAM and consumes around 5 watts, so its ideal to use it for Reddcoin Staking. This tutorial is not from me, i take NO RESPONSIBILITY about these binaries or the accuracy. This tutorial is created by cryptoBUZE, a fellow member of the Reddcoin community. Before attempting to follow this tutorial, do a sudo apt-get update The following commands must be run to install dependencies: sudo apt-get install libboost-thread-dev sudo apt-get install libboost-program-options-dev sudo apt-get install libboost-filesystem-dev sudo apt-get install libboost-system-dev Download and install older libssl version - bitcoin clones are using this glorious and fantastic communist product of openssl so it naturally does not works. Its getting totally incompatible after each relase even with itself. Therefore, you must install this, which is the compatible one with the wallet software (no, you cant even compile the code with the newer one) : wgethttp://apt.screenlyapp.com/raspbian/pool/main/o/openssl/libssl1.0.0_1.0.1t-1%2Bdeb8u6_armhf.deb wgethttp://apt.screenlyapp.com/raspbian/pool/main/o/openssl/libssl-dev_1.0.1t-1%2Bdeb8u6_armhf.deb sudo dpkg -i libssl1.0.0_1.0.1t-1+deb8u6_armhf.deb sudo dpkg -i libssl-dev_1.0.1t-1+deb8u6_armhf.deb Download the wallet software itself: wgethttps://github.com/cryptoBUZE/reddcoin/releases/download/raspberrypi/reddcoind wgethttps://github.com/cryptoBUZE/reddcoin/releases/download/raspberrypi/reddcoin-cli wgethttps://github.com/cryptoBUZE/reddcoin/releases/download/raspberrypi/reddcoin-qt chmod +x reddcoin\* When speaking about compatibility, ARM is similar to x86 if you are running user mode applications. You know that every arm based chip needs a different kernel due to the lack of an unified IO system thankfully for the glorious clueless egoistic communist developers at ARM, who succesfully bankrupted the corporation after 25 or so years, and the company got acquired by the japanese softbank. But in user mode, its sort of backward compatible if you have all the proper libraries installed. This means that this will run on any other newer ARM based machine as well (not just raspberry pi-s, on every other arm stuff, chromebooks, or android phones hacked to work with linux).
Storage space: I am using an 8 GB microSD card for the OS, and a 128 GB USB drive for data. Minimums I would recommend: 8GB SD card and 32 GB USB drive.
Reddcoin Core client version: v220.127.116.11-a8767ba-beta (most recent version at this moment). ↳ Screenshot
You need the OS; Lubuntu. Download Lubuntu (707 MB) for the Raspberry Pi: https://ubuntu-pi-flavour-maker.org/download/. It's a .torrent download, so you will need a BitTorrent client. Message me or post in this thread if you need help with this.
You need software to write the OS to the SD card. I use Etcher. Download Etcher: https://etcher.io/.
Select image: select the lubuntu-16.04.2-desktop-armhf-raspberry-pi.img.xz file.
Select drive: select your microSD card.
Plug the SD card into your Raspberry Pi and power it up.
Lubuntu should boot up.
Set up Lubuntu, connect to the internet (wired or wireless). ↳ As username, I chose "rpi3b". You will see this username throughout this whole tutorial.
Make sure date and time are correct ([Menu] > System Tools > Time and Date). ↳ Click on Unlock to make changes. I personally change Configuration to "Keep synchronized with Internet servers". ↳ Screenshot
Reboot ([Menu] > Logout > Reboot). I am connected to wifi, but have issues getting wifi to work on initial boot. A reboot solves this issue.
Make sure system is up-to-date, install never versions.
Open LXTerminal ([Menu] > System Tools > LXTerminal). ↳ Screenshot
Enter the following in LXTerminal: sudo apt update && sudo apt upgrade ↳ Screenshot
You will be asked if you really want to continue. Enter Y (yes).
Updates are being installed! Wait until it's finished.
Install programs that will be used in this tutorial.
GParted: to partition the USB drive.
Htop: to see the amount of memory (RAM) and swap that is in use.
Enter the following in LXTerminal to install these 2 programs. sudo apt install gparted && sudo apt install htop ↳ Screenshot
Create 2 partitions on the USB drive: 1) Swap partition 2) data partition (for the Reddcoin blockchain) The swap partition is necessary: The Reddcoin wallet can be memory intensive. To prevent any crashes or freezes, add 2 GB of 'virtual' memory by creating a swap partition.
Important: Backup your USB drive if needed. The USB drive will be formatted, so the data on the USB drive will be wiped.
Please use the USB drive solely for this purpose, do not combine it with other stuff.
Keep your USB drive plugged in, do not (randomly) plug it out.
Plug your USB drive in.
GParted will be used to create the partititons. Start GParted via LXTerminal: sudo gparted ↳ Screenshot
Apply the changes. Click on the check mark or select Edit > Apply All Operations. ↳ Screenshot ↳ Screenshot
Important: The name of the swap partition is needed later, so please write it down. Mine is /dev/sda1 (first partition on first drive (drive 'a')). ↳ Screenshot
Reboot. After the reboot, the data partition you just created should be visible on your desktop. ↳ Screenshot
The swap partition is created, so now we can enable and use it.
The swap in use can be monitored with the program Htop. Open Htop ([Menu] > System Tools > Htop) to see the 'Swp' (swap) in use. ↳ Screenshot By default, swap is not used, so 0K. ↳ Screenshot You can leave Htop open.
To enable the swap partition, open LXTerminal and enter the following commands: (Assuming /dev/sda1 is your swap partition.)
Unpack the file (large file, takes around 15 minutes to unpack): sudo xz -d bootstrap.dat.xz ↳ Screenshot
After a successful unpack, your will find the file bootstrap.dat in your USB root folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
The welcome screen will appear and ask you about the data directory. I suggest a new folder on your USB drive, I picked blockchain. The directory will be created with all the necessary files. ↳ Screenshot
Click on the three dots (...) on the right. ↳ Screenshot
Click on Create Folder at the upper right corner. Type and enter in the folder name. (In my case: blockchain.) Click on Open. ↳ Screenshot ↳ Screenshot ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Move the bootstrap.dat file to your data directory you selected in the previous step. By doing this, Reddcoin Core will use the bootstrap.dat file to import the blockchain, which speeds up syncing. sudo mv bootstrap.dat /media/rpi3b/usb/blockchain/ (Assuming blockchain as data directory.) ↳ Screenshot
The Reddcoin Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Keep the client running until it's fully synchronized. It will use the bootstrap file first, and download the rest of the blockchain to complete the sync. This can take some time (it took 2 days for me). Syncing the blockchain uses a lot of resources, so the software may react slow.
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen! ↳ Screenshot
When synchronization is complete, you can start staking your Reddcoins.
You can write down your private key or copy and save it in a document. Make sure you save it somewhere only you can access it.
To import later: Debug window -> Console -> importprivkey [label] [label] is optional. ↳ Screenshot (without a label) ↳ Screenshot (with a label)
Boot with only 1 USB drive plugged in: Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly. If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
Start Reddcoin Core easier Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
Right Click on your Desktop and select Create New -> Empty File. ↳ Screenshot
Enter a file name, make sure it ends with .sh, and click on OK. I've chosen for Reddcoin.sh. ↳ Screenshot The file will be created on your Desktop. ↳ Screenshot
Add the command to start Reddcoin to the file.
Right click on the file, select Leafpad (to open the file in a text editor). ↳ Screenshot
Add the following to the file and save the file: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
To be able to execute the shell script (.sh), it has to have 'execute permissions'.
Right click on the file, and select Properties. ↳ Screenshot
Click on the Permissions tab.
For Execute, select Anyone, and click on OK. ↳ Screenshot
To start Reddcoin Core, double click on the file. A new window will pop-up, asking you what you want. Execute in Terminal is what we want, so you can click on enter. ↳ Screenshot Reddcoin Core will now start. Do not close the Terminal window, you can minimize it if needed.
Minimization options Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
Activate 'Minimize on close'. Settings -> Options... -> Window (tab) -> Minimize on close. ↳ Screenshot Reddcoin will still run when you click on the X button. To close/exit Reddcoin, right click on the Reddcoin icon in the system tray (bottom right corner). ↳ Screenshot
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
After your download is finished, open the file and click Install Package. ↳ Screenshot
To run the VNC Connect once:
Open [Menu] > Run, and enter: vncserver-x11 ↳ Screenshot
To auto run on startup:
Open Default applications for LXSession ([Menu] > Preferences > Default applications for LXSession). ↳ Screenshot
In LXSessions configuration, select Autostart in the menu left.
Under Manual autostarted applications, enter vncserver-x11 and click on + Add. ↳ Screenshot ↳ Screenshot
Reboot your Raspberry Pi and check if VNC Connect is started automatically after the reboot.
When VNC Connect is running, you'll see a VNC icon on the right bottom corner. Double click the icon to open VNC Connect and to see the IP address you need to enter to connect to your Raspberry Pi. ↳ Screenshot

I'm writing this because I couldn't find a single condensed guide on compiling the wallet and running mining software on linux, specficially Ubuntu/Linux Mint. I combed Bitcoin and Litecoin forums for similar problems I was running into and eventually got everything nailed down, so here it is in one place, for new Shibes. If you want to make a Dogecoin directory in your downloads folder to keep things organized, you will need to modify these commands to refelct the change. So instead of going to ~/Downloads/ you will need to go to ~/Downloads/Dogecoin and be sure to put the zipped files there when you download them, but the commands will be the same otherwise. cwayne18 put in the work to make a PPA for the QT client here. Ubunutu/Mint/Debian users should be able to install the client with the following commands:
Compiling the Wallet Manually I suggest using the PPA above, but if you want to compile manually, here you go. 1)Download the newest source from here. If you want to check out the Github page, click here 2)Unzip the package with the native client OR, navigate to your downloads and unzip
cd ~/Downloads unzip dogecoin-master.zip
3)Now it's time to compile. You will need to install the dependencies, just copy and paste the following code. It will be a fairly large download and could take some time. It is always important to update before installing any new software, so we'll do that first and then install the dependencies.
4)Once that is done, go to the doge-coin master directory and compile:
cd ~/Downloads/dogecoin-maste sed -i 's/-mgw46-mt-sd-1_53//g' dogecoin-qt.pro qmake USE_UPNP=- USE_QRCODE=0 USE_IPV6=0 make -j3
After running the qmake command you will likely see some text similar to
Project MESSAGE: Building without UPNP support Project MESSAGE: Building with UPNP supportRemoved plural forms as the target language has less forms. If this sounds wrong, possibly the target language is not set or recognized.
It's perfectly normal, so don't worry about that. Your Dogewallet is ready to go! The executable is in ~/Downloads/dogecoin-maste and called dogecoin-qt. Your wallet information is in ~/.dogecoin. You can run the wallet at any time by opening terminal and typing
cd ~/Downloads/dogecoin-maste ./dogecoin-qt
Future upgrades to dogewallet are easy. Back up your wallet.dat, and simply follow the same directions above, but you'll be unzipping and building the newer version. You will likely need to rename the old dogecoin-master directory in ~/Downloads before unzipping the newest version and building. Also, it is likely that you will not need to install the dependencies again. Alternate Method For Installing Dogecoin Wallet from Nicebreakfast After installing the dependencies listed in step 3, open terminal, then navigate to where you want Dogecoin Wallet stored and run:
git clone https://github.com/dogecoin/dogecoin ./autogen.sh ./configure make
then when the wallet is updated just run
from the dogecoin directory. GPU Mining GPU mining requires CGminer. My suggestion is to get the executable already built. The creator of cgminer has removed the built file from his website, but I've uploaded it here
sudo apt-get install pkg-config opencl-dev libcurl4-openssl-dev autoconf libtool automake m4 ncurses-dev cd ~/Downloads tar -xvf cgminer-3.7.2-x86_64-built.tar.bz2
Don't use anything newer than 3.7.2. The newer versions of CGMiner don't support GPU mining. That's it! You have cgminer ready to go! You will run cgminer with the following syntax
cd ~/Downloads/cgminer-3.7.2-x86_64-built/ ./cgminer --scrypt -o stratum+tcp://SERVERNAME:PORT -u WORKER.ID -p PASS
A good guide for fine tuning cgminer can be found here; follow the litecoin example. EDIT I had trouble getting cgminer running with a single line command, but running it via an executable .sh file works. This is covered in the cgminer setup guide I posted above but I'll put it here too. In the same directory that has the cgminer executable, you need to make a file called cgminer.sh and make it executable. It should contain the follwing:
Then you can call cgminer in terminal by doing ./cgminer.sh You will need a cgminer.conf file containing all your options. All of this is covered in the guide that is linked above. A quick note about AMD drivers: They used to be a huge PITA to install and get working, but the newest Catalyst drivers are great. There's a GUI installer, everything works out of the box, and there is a lot of documentation. You can download them here: AMD Catalyst 14.6 Beta Linux CPU Mining For CPU mining I use minerd because it doesn't require any work to get running, simply download it and get to work. Download the built file for your machine 32-bit or 64-bit, and then unzip it and you're ready to go!
cd ~/Downloads tar -xvf pooler-cpuminer-2.3.2-linux-x86.tar.gz
The executable is called minerd and it will be in ~/Downloads but you can move it to wherever you like. To run it, pull up terminal and do
cd ~/Downloads minerd --url=stratum+tcp://SERVER:PORT --userpass=USERNAME.WORKERNAME:WORKERPASSWORD
You're done! Happy mining! Common Issues I ran into this and I've seen others with this problem as well. Everything installs fine but there is a shared library file that isn't where it should be. In fact, it isn't there at all.
libudev.so.1: cannot open shared object file: No such file or directory
In terminal, do
sudo updatedb locate libudev.so.0.13.0
And it will probably return a path /lib/x86_64-linux-gnu. Inside that directory there's a library file called libudev.so.0.13.0. You'll need to make a symlink (aka shortcut) that links libudev.so.1 to libudev.so.0.13.0 So, assuming you're working with libudev.so.0.13.0 do this
cd /lib/x86_64-linux-gnu sudo ln -s libudev.so.0.13.0 libudev.so.1
Now if you do
You should see
libudev.so.1 -> ./libudev.so.0.13.0
Meaning you've made the symlink. Also, the text for libudev.so.1 will be blue.
Hello, This post is to give you a quick introduction into Bitcoin security. While nobody can guarantee you 100% security, I hope to mitigate some problems you can run into. This is the “20% of effort to get you to 80% safe”. First of all, you have to determine how much money you want to hold in Bitcoin and how much effort are you willing to put in. If you are happy just holding a few dollars worth and don’t care if you lose them, that’s one approach to take. For everyone else, lets get started. Password strength A lot of the times how secure your money is will be determined by the strength of your password. Since in the worst case scenario we are talking about someone trying to brute force your wallet, casual online passwords are too weak. Under 10 characters is too weak. Common words and phrases are too weak. Adding one number to a password at the end is too weak. Moreover, you can consider your password much weaker if you:
use it for multiple online logins (especially if the site could’ve been hacked)
use a common phrase or words (song lyrics are bad)
If you want a really strong password:
Use a trusted website that creates a set of random words offline. For example, CarbonWallet. Go to that website, unplug your Internet, hit random button a few times, write down 10+ of these words, restart your computer, memorize them, destroy the paper once your done. This should make your password pretty strong.
If you are extra paranoid, you have to get creative. Do something with your password that you can remember - maybe add some numbers at the end, do some substitutions, capitalize some letters and so forth. As long as you are not removing words or changing unique words for more common ones, personalizing or extending your password can add more security.
Wallet security Now we are getting to the meat of things. There are a number of wallets available to store your hard earned bitcoins. If you have a decent amount of coins to store, you should look into software wallets - BitcoinQT, MultiBit, Armory or Electrum. They are among the best place to store your money safely (provided your computer is secure as well). Chose one you think best suits you, install it and encrypt your wallet file with your strong password. You should take your wallet file and back it up (location of the file is different for different clients, so you have to do some research as to where to find that file). Back it up on a CD, safe USB drive or the like. Keep them safe. If you lose that file, you will lose your money. A quick word on deterministic wallets. Electrum and Armory allow you to create wallets from a seed. If you use the same seed later, you can recreate your wallet on other machines. With deterministic wallets, you only need to keep that seed secure to have access to your money. In comparison, in BitcoinQT's traditional wallet, every address you use is random, meaning that after you send 50-100 outgoing transactions your backups can be obsolete. Always keep an up-to-date backup of such wallet file if possible. Okay, sometimes you need to have your Bitcoins with you when you leave your computer. In this case, you should look into either online or mobile wallets. A staple for both of those is Blockchain.info, but there are others to chose from. A good rule of thumb with these is to not store more money in them than you can afford to lose. They are best used as a convenient way of accessing some money, not storing your savings. Online wallets are especially vulnerable to their servers getting hacked and people’s money getting stolen. What to keep in mind while using online wallets:
Use a secure password (the more money you have in them the stronger the password should be)
Always keep a backup of your wallet in case you need to recover your money
Whenever possible, enable two factor authentication
Don’t use your online wallets from unsafe computers
Cold storage Sometimes you want to store your bitcoins for a long time in a safe place. This is called “cold storage”. There are a few ways one can do this. First of all, paper wallets. They are nice for giving people small bitcoin gifts, but also for long-term storage if properly used. What you want to do is generate and print them offline. You can save the linked page for example and run that offline. If you are really paranoid, you can put it on read-only media and access that from a different computer. For really long term storage, use archival-grade paper. Another approach to take is using a separate computer for storing your money that is offline 99+% of the time. You could set one up easily by buying an old laptop, reformatting it, installing Linux and a Bitcoin client. Generate an address on that machine and send money to it from your main wallet. Depending on how paranoid you are you can connect that computer to the Internet afterwards to synchronize data with the Bitcoin Network and then turn it off and put it away somewhere safe until it’s needed. Brain wallets Don’t. They are not for you. Unless you are a security-conscientious programmer, those are not for you. Diversifying Keeping all of your eggs in one basket is never a good thing. You should look into diversifying some of your Bitcoin assets in case your other storage methods fail. Some ways you can diversify:
Buy a physical Bitcoin. As long as you trust the coin creator such coins can be an effective cold storage
Invest - I wouldn’t recommend this for more than some trivial amount unless you know what you are doing, but investing in some Bitcoin stocks could be a way to get more money out of your bitcoins
How not to diversify:
Avoid keeping your bitcoins at exchanges or other online sites that are not your online wallets. Such sites can be closed down or disappear along with your money.
Alt-coins - there are few cryptocurrencies that are worthwhile, but most of them are just Bitcoin clones. If a currency brings nothing new, it’s worthless in comparison to Bitcoin. Namecoin is a distributed domain name server (although recently it had a fatal flaw uncovered, so be warned), Ripple is a distributed currency exchange and payment system. Litecoin will only be useful in case Bitcoin’s hashing algorithm gets compromised (very unlikely at this time). Beyond that there are few if any alt-coins that are a worthwhile way of diversifying.
Accepting payments and safety We’ve covered safe ways to store money, now a quick note about bitcoin payments and their safety. First of all, when you are sending a transaction, pay your fees. Transactions without fees can take forever to propagate, confirm and clear. This can cause you a lot of stress, so pay your fees. Secondly, when accepting large Bitcoin payments (say you want to suddenly cash in a gold bar into bitcoins), wait for at the very least 1 confirmation on those transactions. 6 is best, but having even 1 confirmations is a lot better than having none. This is mainly a rule of thumb for the paranoid (I wouldn’t be doing this for most casual transaction), but maybe it will save you if you are dealing with some shady people. Wrapping up... That should cover the basics. If you want to read more about Bitcoin’s security in general, here is my master thesis on the subject. A lot of questions about Bitcoin and security have also been answered on Bitcoin StackExchange - be sure to check it out. Comments and improvement suggestions welcome. EDITS:
... no more. Hello everyone, I retried installing the wallet client and have taken screenshots, so to document my problems and get help. Well, now it is working just fine on Linux Ubuntu... way easier setup than Lisk or Monero.... Analysis: I have deleted the corrupted pivx folder and wallet. I rebooted the system. Went to pivx.org/wallet. Downloaded the 3.0.5-x86_64-linux-gnu.tar.gz . Unpacked it with engrampa. Ran pivx-qt through right klick and execute/run and the wallet opened. Currently synching the network. Now I will go and buy those 500 PIVX back. And I honestly do not know, why that did not work yesterday. Thanks to everyone who offered help!!! and shame on me for posting in such an overreactive way. I will leave the thread and the original post below, so things stay transparent for redditors or the mods agree to deleting it. As a thank you for offering so much support, I made a short how-to on medium, actually my first article there :) https://medium.com/@clausfroehlich/installing-a-pivx-wallet-on-ubuntu-linux-a45d2491e3a8 Best regards Melchior Hi Pivx supporters and developers, I am a biologist and have been watching the cryptospace since 2012. Since 2014 I have been in bitcoin and since this year also in ALTs. Although lacking deeper knowledge concerning hard- and software I have been able to switch from Windows to Linux Ubuntu without major problems, setting up wallets for bitcoin, eth, xmr and ark. Of course this is due to those projects either offering sufficient tutorials or supporters presenting ELI5-like tutorials on YouTube, steemit, medium, etc. Tonight I wanted to setup a pivx wallet, transfer funds and stake, however, I did not even succeed in the first step. I tried searching around the web, no good guidance available. Actually, I got so frustrated, I just sold my pivx and rather invest and stake somewhere else... of course I could ask friends to help me, you say. But that is not my point, my point is usability to get wider adoption. That is not the case with pivx right now. I will lurk around however and come back in case you develop this to be a currency for non-tec users as well. Best regards to all of you.
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).
Because release 0.10.0 and later makes use of headers-first synchronization and parallel block download (see further), the block files and databases are not backwards-compatible with pre-0.10 versions of Bitcoin Core or other software:
Blocks will be stored on disk out of order (in the order they are received, really), which makes it incompatible with some tools or other programs. Reindexing using earlier versions will also not work anymore as a result of this.
The block index database will now hold headers for which no block is stored on disk, which earlier versions won't support.
If you want to be able to downgrade smoothly, make a backup of your entire data directory. Without this your node will need start syncing (or importing from bootstrap.dat) anew afterwards. It is possible that the data from a completely synchronised 0.10 node may be usable in older versions as-is, but this is not supported and may break as soon as the older version attempts to reindex. This does not affect wallet forward or backward compatibility.
The pools are all reporting the wrong network data (I hope its this - but the rate of discovery of blocks by pools would suggest otherwise)”

Everyone focuses on botnets because it has been so long since regular users were able to effectively mine a coin (due to every coin rapidly going high end GPU and ASIC) that the idea that "users" could vastly outnumber "miners" (botnet or otherwise) isn't even on the radar. The vision here is a wallet that asks you when you want to install: "Do you want to devote some of you CPU power to help secure the network. You will be eligible to receive free coins as a reward (recommended) [check box]." Get millions of users doing that and it will drive down the value of mining to where neither botnets nor professional/industrial miners will bother, and Satoshi's original vision of a true p2p currency will be realized.

Other coins do use the word anonymous improperly, so we too have to play the marketing game. Most users will not bother looking at details to see which actually has more privacy; they'll assume anonymity > privacy. In a world with finite population, there's no such thing as anonymity. You're always "1 of N" possible participants. Zero knowledge gives N -> everyone using the currency, ring signatures give N -> your choice, and CoinJoin gives N -> people who happen to be spending around the same amount of money as you at around the same time. This is actually the critical weakness of CoinJoin: the anonymity set is small and it's fairly susceptible to blockchain analysis. Its main advantage is that you can stick to Bitcoin without hard forking. Another calculated marketing decision: I made most of the OP about ring signatures. In reality, stealth addressing (i.e. one-time public keys) already provides you with 90% of the privacy you need. Ring signatures are more of a trump card that cannot be broken. But Bitcoin already has manual stealth addressing so the distinguishing technological factor in CryptoNote is the use of ring signatures. This is why I think having a coin based on CoinJoin is silly: Bitcoin already has some privacy if you care enough. A separate currency needs to go way beyond mediocre privacy improvements and provide true indistinguishably. This is true thanks to ring signatures: you can never break the 1/N probability of guessing correctly. There's no additional circumstantial evidence like with CoinJoin (save for IP addresses, but that's a problem independent of cryptocurrencies)."

March 2015 – tail emission added to code
March 2016 – monero hard forks to 2 min block and doubles block reward

Crippled miner Gave unfair advantage to those brave enough to risk money and time to optimize and mine Monero.
Fast curve emission non-bitcoin-like curve as initially advertised and as it was widely accepted as suitable
Though we have to say two things to support current Monero community and devs:
The crippled miner was coded either by Bytecoin or CryptoNote, and 100% solved within a month by Monero community
The fast curve emission was a TFT miscalculation. He forgot to consider that as he was halving the block target he was unintentionally doubling the emission rate.
