HOdlcoin (HODL) Getting Ready For Another Hardfork

4, May 2017

Last year we were actively following the development of the HOdlcoin (HODL) project up until there was a hardfork that essentially killed our interest in the coin. The Hardfork to version 2.0 introduced the rule that all new mined coins will automatically be staked for 1 year and also made obsolete the need of mining pools. As a result not only we lost interest, but many users that deemed the project interesting also did and from there on things pretty much started moving on a downwards spiral. Fortunately recently there was a decision for a new hardfork in order to bring back the regular mining as it was before the weird decision from the previous hardfork.

In order to get ready for the upcoming hardfork you need to upgrade to the latest HOdlcoin Core wallet version 3.0 before the network reaches a block height of 257000 when the hardfork will be activated. There is still some time left before the hardfork as the current block is 244607 and you can track how things progress via the official HODL blockchain explorer. The new wallet comes with some long awaited improvements such as tables sorting of the deposits, improved mining performance and some bugfixes.

Up until recently HOdlcoin (HODL) was only traded on the Yobit Exchange, though after the announcement for the upcoming hardfork there is a new altcoin exchange on board as well – Coinexchange. There is still only one HOdlcoin Mining Pool available by Optiminer, though we might be seeing some more getting back on board after the hardfork. The latest best performing miner for HODL is the Hodlminer Optimized Optiminer fork that you can use to mine on the only available pool. Do note that before the hardfork hits all mined coins (solo or on the pool) will still be held for a 1 year term deposit in your wallet before becoming available.

The big question now is what is hodl tokens / khrif stock and can it recover and bring back sufficient user interest after the hardfork including miners. Currently the available hashrate on the Optiminer mining pool is about 20000 H/s with just about 35 miners. The biggest problem in bringing back user interest lies in the concept that the coin initially had with high interest rates on deposits and bonuses as these are already pretty low compared to the levels they were at last year. Still we are going to be keeping an eye on HODL to see how things will develop after the hardfork…

New Faster HODLminer and a New Mining Pool For It Now Available

3, Aug 2016

hodlminer-optiminer-fork
Recently, hodl crypto has implemented a hardfork that changed the way mining works for the coin essentially driving away miners in favor of the people that already hold the coin. The change required mined coins to be help for 1 year before being released to users for use, so the existing pools kind of gave up on continuing as they usually operate on a mining fee and miners fled from the coin. The only way that was left to mine was using the in-wallet built-in miner that is slower than the already existing miners that could be used only for pool mining. The only advantage that was left was that the mined coins from 50 per block when mined would gain interest and would be much more when they were released to the user. Regardless this kind of made us loose interest in HODL for the moment as here we like coins that can be mined…

Recently there has been new somewhat positive development that may bring some miner back to mining HODL or at least trying to as the 1 year waiting time for the coins to be released is still there. Anyway, there is a new further optimized HODLminer forked by optiminer from Wolf’s code that does provide significant performance improvement (source). Below you can find a 64-bit Windows binary of the miner that you can use to mine HODL on your CPU, do note however that you still need to have a more recent AMD or Intel processor with AES-NI support in order to use the miner. You should also be able to use the slower non-AES-NI capable miner that you can find here for older CPUs without the required instruction support. Do note that you should be able to use this miner for other coins that rely on the HODL algorithm as there are apparently some already available such as ERC.

Performance for Intel Core i5820K CPU:
– Old Wolf HOLD miner: 250 H/s
– Optimized Optiminer fork: 560 H/s

The new miner however would be useless without a dedicated mining pool (it does not work with solo mining using the HODL wallet), so the same author also launched Optiminer HOdlcoin Mining Pool where you can point the miner to mine HODL for you. It is a PPLNS pool with 1.0% fee and requires 25 confirmations until a pending block counts as mined. Do note that all HODL coins are still locked for one year after mining as there is currently no way to withdraw the balance for miners. Instead, once the balance reaches at least 50 HODL, it gets eligible for including in a mining block. The next block will always be mined to the address of the miner which has the highest eligible balance at which point you would still have to wait for 1 year to actually be able to use these mined coins.

Windows Binaries for the cpuminer-opt 3.3.8 CPU Miner

24, Jul 2016

cpuminer-opt-3-3-8

Another update in the form of a Windows binary compiled from the latest cpuminer-opt (source) CPU miner with added optimizations for many algorithms using the AES-NI instruction set (also works on older SSE2 capable CPUs). Up until recently the cpuminer-opt was available only for Linux users, but starting from version 3.3 there is also Windows support and we have compiled 64-bit binaries of the miner for Windows for the latest released version 3.3.8. The latest update brings some performance improvements such as blake2s with about 10% higher hashrate, support for new algorithms such as LBRY, Whirlpool and WhirlpoolX as well as fixed Skein2 that was apparently broken in the previous version.

In the archive below you can find multiple executable files that are compiled for different CPU architectures that support AES-NI instructions, so you are welcome to try them to see what works best for you. If your processor does not support AES-NI (CPUS introduced 5 or more years ago), then you might want to use the cpuminer-sse2.exe binary. The default cpuminer.exe is compiled for Intel Westmere, the first Intel architecture that has support for the AES-NI instruction set and cpuminer-amd.exe is bdver1 which should work on all AMD processors with AES-NI support. If you have a more recent Intel Sandybridge, Ivybridge, Haswell or Broadwell-based processor you can try the respective binary to see if that will squeeze some extra performance, or you can compile directly on your PC with the native instruction set supported by your CPU.
