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, thouhg 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 if HOdlcoin (HODL) can 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…

Recently HodlCoin (HODL) 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.

We have compiled a new range of windows binaries of the hodlminer fork optimized by Wolf0 (source) with support for Intel AES New Instruction set (AES-NI). This is the faster CPU miner for mining HOdlcoin (HODL) than the standard release for processors without AES-NI support. Do note that the binaries below are available only for 64-bit Windows and will work only on compatible AMD or Intel processors with AES instruction support, for other processors you should stick with the standard hodlminer that is slower, but should work on much wider range of CPUs.

If you are not sure if your CPU does have support for AES-NI and what it the architecture it is based on you can easily check with the help of the free tool CPU-Z. Intel’s CPUs with AES-NI support start from the first models based on the Westmere microarchitecture that was introduced in early 2010 while AMD’s processors that do come with AES support start with the AMD Bulldozer Family 15h introduced in late 2011. This means that if you have a CPU later than that it will most likely have support AES-NI, though there is a catch, not all lower-end CPUs come with Advanced Encryption Standard Instruction Set supported. Intel has a list of all CPU’s that have support for AES-NI available here, so you can also use that to see if your CPU is in the list.

In the archive below with the different binaries there are number of executable files that have the type of michroarchitecture they are compiled for, so you just need to rename them to hodlminer.exe and try to run them depending on the type of CPU you have. The binaries with bdver1, bdver2 and bdver3 are for AMD CPUs with Bulldozer or later michroarchitecture while the others are for Intel starting with Westmere, then Sandy Bridge and Ivy Bridge and then Haswell and Broadwell. The Silvermont michroarchitecture is for specific set of low-power Atom, Celeron and Pentium branded processors used in systems on a chip (SoCs) made by Intel that aslo have support for AES-NI. If these binaries do no work on your processor, the standard hodlminer release should still be able to provide you with the ability to mine HOdlcoin (HODL).
