ethereum-hard-fork

The plans for the upcoming Ethereum hard fork that is designed to fix the issues around the DAO situation have been published, with the hard fork planne to take place at block number 1922000 that should hit around 20th of July though it may depend on your time zone. The idea is to have the hard fork take place shortly before the 21.07, which is the date in which the DAO attacker can split. Some of the Ethereum clients such as Parity and the most widely used Geth have a hard-fork implementation for The DAO now, though they have not released updates for the hard fork yet. Other clients like pyethereum, or libethereum already started their implementations of the hard-fork, so it is certain that they will release a new version including the hard fork with the same date. Do note that you will need to update your local Ethereum client before the planned block in order to ensure that you will be able to continue using it after block 1922000. With hard forks you need to update your client in order for it to continue operating properly on the network as it includes mandatory changes making older releases incompatible.

Ethereum is also extending their bounty program to include vulnerabilities found in the hard fork specification. This includes the specification itself, the associated smart contract code that is defined in the specification, and the implementations in geth, cpp-ethereum, parity, and pyethapp clients. So people that find issues in the code and report them can be rewarded for their efforts and at the same time they will be making Ethereum safer and more problem free for use in the future.

ethereum-blockchain-file-size

It is not even a year since the mining of Ethereum’s Ether (ETH) coins has started and due to the short block time and the huge user interest the total size of the blockchain data of Ethereum has already grown huge and continues to grow rapidly. The current size of the Ethereum blockchain data files is already over 16 GB and just about two months ago it was a bit over 9 GB. With the increasing demands for storage to host the full blockchain data as a part of a local wallet or a full network node more users might be switching to online wallets and other services that do not require the user to have a local copy of the data files such as exchanges for example. With more users getting into Ethereum the number of transactions on the network is also growing and by the time when the switch from PoW to PoS phase happens we could even have Ethereum’s blockchain size getting close to that of Bitcoin. If you look only at ETH alone even 20 GB might not be that much, but if you have a local Bitcoin wallet as well as a few other crypto wallets installed on a PC with the full blockchain stored locally you might even start experiencing issues with available free space and things will only get worse with the fast increase of the size of the blockchain data.

genoil-ethminer-1-0-7

We have compiled a Windows binary (64-bit only) from the latest ethminer 0.9.41 Genoil fork 1.0.7 beta for Nvidia CUDA as well as AMD OpenCL mining of Ethereum (source). The latest code comes with the addition of failover support for Stratum mode along with the already available in previous release failover support for the standard mining mode. You are welcome to download and try the compiled binary of the latest git code for the new 1.0.7 beta and the Stratum failover and if you experience problems you should report them. Check the included help.txt file and the example BAT file for more information on how to use the new Stratum failover mode. We are also seeing a tiny bit of performance increase on Nvidia using the CUDA mode and apparently using the OpenCL on Nvidia should now also provide similar performance as CUDA (was slower before), there should not be no change in hashrate on AMD GPUs.
