With Bitcoin’s blockchain data files already over 50 GB in size and Litecoin’s blockhcain size approaching 7 GB there are some concerns rising about the rapidly growing in size blockchain of Ethereum. While BTC and LTC are already a few years old and established and used crypto currencies, Ethereum is still fairly new and in just little over 3 and a half months the blockchain size has already reached 2.9 GB in size. Now, imagine what will happen in a few years of use with the adoption rate and numbers of transactions increasing… it could easily catch up to the size of the Bitcoin’s blockchain. In fact the amount of data that the blockchains of crypto currencies take is starting to become an issue for everyone that is running a full local node and things will get worse as crypto currencies will need more and more space to store the data on your hard drive. This will make online wallet services and light wallets more attractive, but we do still need a lot of full nodes running in order to secure the network of any crypto currency. So not only the matter about the block size for Bitcoin should be discussed, but also the matter about the total blockchain size and that goes for other crypto currencies as well. It is even more of an issue with crypto currencies such as Ethereum that have faster block times, making them generate more blocks in less time.

ethereum-wallet

Finally there is work being done on an official GUI wallet for Ethereum that is curiously hosted in the Ethereum Mist Dapp Browser GitHub repository. Do note that this is a beta release that although functional could have some issues and is some advanced functionality is still not implemented, but the idea in this release is to get user feedback and to find any bugs. This is an official Ethereum GUI wallet that currently works along a Geth client as a backend, but should also be compatible with the Eth as well. The Mac and Windows 64-bit releases come bundled with Geth node and if you are not using it already it will need to synchronize the blockchain at the first start, otherwise it should tap to the already downloaded blockchain (already over 1.7 GB size) and work with any wallets available (backing the keys first is recommended). For other binary releases you would need to have the Geth (or Eth) client already running and then launch the Wallet GUI in order for it to work. Again, since this is a beta software it is best if you try it out on a system where you do not have a working Ethereum client installed in order to avoid any possible issues.

Another interesting development around Ethereum lately is apparently the start of adoption of Stratum support, there is the Stratum-Proxy for Ethereum project supported by Dwarfpool as well as the news that EthPool is working on a stratum enabled fork of Ethminer called qtminer that will be supported on their mining pool, but may get adopted by other pools. The current getwork implementation by Ethereum is not very practical and effective as compared to the Stratum implementation that is currently the standard for communication between pools and miners.

etherwaller-paper-wallet

This is an interesting and quite useful tool for people willing to generate an Ethereum wallet without having to install an Ethereum client on their computer for the moment. Ether Wallet is a web-based service that is in the form of a client-side tool (no data is being sent to a server) for generating Ethereum wallets, Ethereum paper wallets and even to send transactions over the network. EtherWallet is an open source and written in JavaScript client-side tool, you can download the source code here and run it directly from your own computer if you have some privacy worries about the wallets generated on the website.

You can of course import your Ethereum wallet generated with Ether Wallet, even if you printed a paper wallet, into geth for example with your unencrypted private key that you need to save into a file. All you have to do is to run the geth client with the following command line where instead of keyfile you need to type the file name of the file you have saved your unencrypted private key in:

geth account import keyfile

You will be asked to enter a password in order to encrypt the key when your account is being imported in geth and the password you enter will be needed in order for you to unlock your account for executing transactions in the future. So make sure you remember your password and then do a backup of your Ethereum wallet in geth.
