| Random Cryptocoin |
Bytecoin (BCN) is a decentralised, anonymous cryptocurrency written from scratch and launched in July 2012. Its concept is based on the CryptoNote technology which focuses on privacy and anonymity of transactions. It comes with a number of unique features, such as ring signatures to make payments untraceable, an exchange protocol to make transactions unlinkable, and several others. Some other interesting features of the cryptocurrency include "egalitarian" proof-of-work mechanism and an analysis-resistant blockchain. Bytecoin is designed to be easily mined on an average personal computer while being resistant to mining with specialised ASIC hardware. The Bytecoin software is available in two variants - as a Bytecoin reference client that uses a command-line interface to manage transactions and to mine coins, or a Bytecoin wallet with an easy-to-use an intuitive graphical user interface.

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 hashrate is the measuring unit of the processing power used to perform energy-intensive computations to maintain the Bitcoin network (or the network of any "mined" cryptocurrency). It is commonly expressed in gigahertz per second (GHz/s). As an example, a hashrate of 1 GHz/s means that the combined Bitcoin network of connected computers is capable of making one billion calculations per second. In the first quarter of 2015 the Bitcoin network's hash rate oscillated around the 350,000,000 GHz/s mark, thus performing 350 quadrillion calculations every second. In contrast, the hashrate of Litecoin, the second most popular cryptocurrency, stood at around 1,200 GHz/s - just 0.0003% of Bitcoin's hashrate.

The Gulden project has announced the release of Gulden (NLG) 1.6.0, a new version of the project's proof-of-work cryptocurrency that is rapidly gaining popularity and acceptance throughout the Netherlands. This release represents a major update: "Our entire wallet has been redone to bring massive and much needed usability improvements: HD desktop wallet with mnemonic (recovery phrase) support; fully backwards compatible with recovery phrases from older Android and iOS wallets; fully integrated accounts within wallet physical separation between accounts; back up all your accounts with just a single recovery phrase; fully link your funds between specific accounts and your mobile devices, for fund management across devices with unprecedented ease; pay bitcoin or IBAN directly from your desktop wallet via seamless Nocks integration...." See the release announcement (in Dutch), with further information provided in the developers' blog (in English). Download (SHA256): Gulden160-linux64.tar.gz (32.4MB), Gulden160-linux32.tar.gz (32.7MB), Gulden160-mac.dmg (40.0MB), Gulden160-win64.exe (33.2MB), Gulden160-win32.exe (32.0MB). A recent bootstrap file for faster synchronisation with the Gulden network is also available: bootstrap_20151114.rar (151MB). |

NEW • Cryptocurrency Release: Gulden (NLG) 1.5.5 |
4,290 satoshi
|
An updated build of the Gulden (NLG) wallet client, version 1.5.5, is now available for download. This is a security update that was developed in response to the recent attempt to exploit the "51% attack" vulnerability in the Dutch cryptocurrency's proof-of-work algorithm; read this news post (in Dutch) for more details. The Gulden's way to reduce the risk of recurrence of such attacks is related to the way the blocks of transactions are "checkpointed", or verified for correctness at regular intervals. All users and miners are strongly encouraged to update their software and as soon as the majority of users run this version, the new security measures in the code will also be activated. Mobile clients do not currently require an upgrade. Here is the release announcement for Gulden 1.5.4 (in Dutch) which was quickly replaced by a bug-fixed version 1.5.5. The new Gulden clients for Linux, OS X or Windows are available for download from here: Gulden155-linux64.tar.gz (33.9MB), Gulden155-mac.dmg (11.2MB), Gulden155-win64.exe (12.9MB). For those readers who'd like a detailed look at the recent changes or who prefer to compile their own wallet clients, here is a quick link to the source code: v1.5.5.tar.gz (5.67MB). |

NEW • Cryptocurrency Release: Gulden (NLG) 1.5.2 |
4,290 satoshi
|
The Gulden development team has announced the release of Gulden (NLG) 1.5.2, the latest stable build of the Dutch cryptocurrency project's wallet client. Although not a mandatory upgrade as the new wallet contains only minor technical improvements, it is still recommended that users stay up-do-date. One of the major changes in this version is a bug fix regarding the maximum transaction size. As a result, it is now easier to do transactions with larger transaction sizes which should greatly benefit those users who perform a large number of smaller transactions. Furthermore, it is now also possible to download a separate bootstrap file and to synchronise a newly installed wallet with the full Gulden blockchain faster. Read the brief release announcement (in Dutch) for further information. Download the new Gulden client for Linux, OS X or Windows: Gulden152-linux64.tar.gz (39.7MB), Gulden152-mac.dmg (12.6MB), Gulden152-win64.exe (13.1MB). As always, a quick link to download the source code: v1.5.2.tar.gz (5.66MB). This release also completes the recent move to rename the cryptocurrency from Guldencoin to Gulden, together with new domains at Gulden.com and Guldenweb.com. |

NEW • Cryptocurrency Release: Guldencoin (NLG) 1.5.0 |
4,290 satoshi
|
The development team behind Guldencoin, a Dutch cryptocurrency project, have announced the release of Guldencoin (NLG) 1.5.0. This version comes with a number of changes to the code base (mostly backported from Bitcoin 0.10 and some from Bitcoin 0.11) as well as the user interface which has been made more attractive. This is a mandatory upgrade. Some of the changes include: faster blockchain download and synchronisation; new multi-signature feature requiring more than one authorisation before a transaction can be executed; smart contracts for services that want to make use of the new multi-signature feature; the watch-only address feature is does no longer depend on blockchain explorers with associated APIs; built-in certificate that prevents virus scanners from raising false alerts; new block reward starting with block 250,000 - the reward will be reduced from 1,000 NLG to 100 NLG. Read the full release announcement (in Dutch) for more details. Download the new Guldencoin client for Linux, OS X or Windows: Guldencoin150.tar.gz (17.4MB), Guldencoin150.dmg (11.1MB), Guldencoin150-32.exe (11.2MB). The source code is available from a new location (guldencoin-official) at GitHub: v1.5.0.tar.gz (4.19MB). |

NEW • Cryptocurrency Release: Guldencoin (NLG) 1.4.0 |
4,290 satoshi
|
The Guldencoin project has announced the release of Guldencoin (NLG) 1.4.0, a brand-new version of its wallet client and a mandatory upgrade that needs to take place before Sunday, 17 May (starting from block 213500). Originally a proof-of-work cryptocurrency that uses the scrypt algorithm for mining guldencoins, the new wallet has now changed its way of adjusting mining difficulty to a concept called "DELTA", developed in-house. This is in response to recent developments in scrypt mining, notably the increased activity by ASIC mining which concentrates the mining (and the rewards) into the hands of those who can afford to buy large pools of specialised hardware. The project's new difficulty adjustment mechanism defies not only ASIC mining, but also a phenomenon known as "jump pool" where increased computing power is applied at a "correct" time with high likelihood of coin generation. DELTA represents a response to this development, aiming to cope better with power fluctuations so that the stability of the network is improved. Further work, notably a possible switch to multi-algorithm mining, is also on the agenda for a future release. Read the release announcement (in Dutch) for more information. Download links: Guldencoin140 (10.4MB), Guldencoin140.dmg (11.2MB), Guldencoin140.exe (20.5MB). The source code is available from GitHub: v1.4.0.tar.gz (16.4MB). |
