| Random Cryptocoin |
Groestlcoin (GRS) is a decentralised, open-source cryptocurrency forked from Bitcoin in March 2014. The project's focus is to enable anybody with a standard computer to mine coins, using either the computer's central processing unit (CPU) or its graphcs processing unit (GPU). Groestlcoin is a hybrid proof-of-work/proof-of-stake coin which uses the ASIC-resistent Grøstl hashing algorithm to complete proof-of-work blocks. Starting at block 150,000, coins can also be generated by "staking" at a 2% annual interest. The total number of coins was set to 105 million, with the initial block reward at 25 GRS; this is reduced by 6% every 10,080 blocks. The block time is 60 seconds, while the difficulty is recalculated after each completed block of transactions. Original announcement.

BitKey is a FREE, Debian-based live Linux distribution designed for Bitcoin users; it comes with specialist utilities to perform highly secure air-gapped Bitcoin transactions. It contains a swiss army knife of handy Bitcoin tools that support a wide range of usage models, including a few very secure ones which would otherwise be difficult to perform. The system boots into one of the three available modes: "cold-offline" - for creating a wallet and signing transactions; "cold-online" - for watching the wallet and preparing transactions; "hot-online" - standard usage but less secure as the private keys are known to the computer which is connected to the internet.

The genesis block is the first block of a blockchain, a cryptocurrency's ledger of transactions. It is assigned the value of 0. The genesis block may contain a text message written by the developer of the software; for example Bitcoin's genesis block famously includes a variable called "coinbase" which reads (in encrypted form): "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks". This refers to a newspaper headline, published on the day of Bitcoin's launch, revealing Satoshi Nakamoto's indignation over the way politicians handled the financial crisis that engulfed much of the banking and financial world at the time.

NEW • Cryptocurrency Release: Fluttercoin (FLT) 0.7.5.19 |
|
Fluttercoin developer "ofeefee" has announced the availability of a new version of Fluttercoin (FLT), a hybrid proof-of-work/proof-of-stake cryptocurrency with an additional way of generating coins - a "proof-of-transaction" mechanism where new coins can be created simply by circulating the existing ones in transactions. Once again, the release notes provide scant details and the list of changes tells us that there have been just seven commits since the release of version 0.7.5.18 back in September 2015 (with the most recent one dated some 10 months ago). Perhaps the biggest addition is a new theme pack for the Fluttercoin wallet client: "Fluttercoin v0.7.5.19 release. Added RPC functions to control stake split thresholds, set to keep your blocks from splitting on specific sizes. Theme pack - extract to the application directory (fluttercoin/themes), relaunch client to select modified themes." Fluttercoin is currently ranked 482 by market capitalisation (according to CoinMarketCap.com), the project no longer has a working website and binary clients are provided for Windows only. Download: fluttercoin-64-windows-v0.7.5.19.zip (13.2MB), fluttercoin-32-windows-v0.7.5.19.zip (12.3MB). The source code is also available: v0.7.5.19-flt.tar.gz (2.26MB). |

From the release notes: "0.7.5.16 release. New features: Traffic Graph - Menu - Tools - Traffic Graph; referral option for Fluttershare - refer your friends to run the wallet, and enable Fluttershare Free; added '-change' option for daemon or Qt that forces change to a specific address, Fluttershare and coin control change systems override this, but this happens before it creates a random 'change' address.
