16 September 2017   1377

A new version of Ethereum's Geth node software has been released. In addition to a series of performance enhancements, the update includes support for "Byzantium".

According to the developers, the update, named Megara, is the first incarnation focusing on laying the groundwork for the upcoming Metropolis hard forks (Byzantium and Constantinople), consisting of 125+ code contributions for various parts of the project.

Byzantium fork

As reported, the release has been reformatted to include all improvements developed for Byzantium, which forms the first of two parts in the wider "Metropolis" update. Megara also includes a formal block number for the launch of Byzantium on Ropsten, the Ethereum testnet. The block number is now officially 1,700,000, which seems to be reached in about seven days.

Performance optimizations

The 1.7 release series of Geth is also aimed to focus primarily on performance improvements. Among the performance enhancements are steps to cut the amount of data storage required by a node from 26.3GB to 14.9GB – making ethereum significantly lighter to run. Updated nodes will also be able to process contracts faster, with filtering times reduced from minutes to under a second.

Trezor wallets

The team has introduced support for the Ledger hardware wallet. Due to popular demand, it has been expanded on hardware wallet support to include the Trezor. The Geth console can be used to unlock the Trezor, which will request the user to enter the shuffled PIN code and send that over to the Trezor for verification.

Transaction journal

According to the team, Geth 1.7.0 journals all locally created transactions to disk and loads them back up on a node restart. This ensures that even if the originating node goes offline, cheap transactions still have a chance to be included when the node comes back. The transaction journal can be an enormous help for node operators during software upgrades by not having to worry about local transactions going missing. Furthermore, the journal also acts as a resiliency mechanism against node crashes, ensuring that no transaction data is lost, as the company details.

Rinkeby updates

As reported, there have been a lot of fine-tuning of Puppeth and Rinkeby over the course of this release, such as better ethstats logging to detect malicious reporters and IP address blacklisting to deny access for them.

'Kodak Miner' Turned Out to be a Scam

KashMiner by Spotlite USA was promoted as Kodak branded bitcoin miner

The KashMiner bitcoin miner, exhibited at the Kodak stand during the CES technology show in Las Vegas, was in fact a product designed to mislead potential consumers and with a potentially unattainable potential return. This is reported by BBC.

Spotlite USA is licensed by Kodak's lighting division, which allows it to use the famous brand in its products. In January 2018 the company introduced its miner and announced that it intends to lease it. According to its business plan, potential users had to pay a commission before getting the device. It was expected that after depositing $ 3,400, the customer will receive a device that will allow him to easily cover expenses and receive revenue from bitcoin mining.

However the company did not have an official Kodak license to use the brand in the production of mining equipment and initially overstated the indicators of the potential profit of its device, refusing to take into account the growing complexity and costs of bitcoin mining. The advertising materials reported that KashMiner brings $ 375 a month, which, subject to a 2-year contract, would allow the client to receive $ 5,600 of profit after paying a commission. Experts from the industry of cryptocurrency call this offer a scam.

There is no way your magical Kodak miner will make the same $375 every month.

CEO Spotlite USA Halston Mikail previously reported that he plans to install hundreds of miners at the headquarters of Kodak. According to him, he already managed to place 80 miners there, but the Kodak spokesman denied this information.

While you saw units at CES from our licensee Spotlite, the KashMiner is not a Kodak brand licensed product. Units were not installed at our headquarters.

In a phone call with the BBC, Spotlite's Halston Mikail said the US Securities and Exchange Commission (SEC) had prevented the scheme from going ahead.
