Byzantium delayed

The planned hardfork of the Ethereum, Byzantium, is postponed for at least a week

Byzantium activation should occur on the block 4,370,000, and at the current block generation speed this will happen on October 17, reports CoinDesk.

Initially, the activation of Byzantium, the first stage of the Metropolis hardfork, was scheduled for October 9, provided that no problems were found during the testing.

The news about postponement of the date of the hardfork was preceded by the comments of the of Vitalik Buterin, founder of Ethereum, that the platform should be conservative with respect to previous forks.

At the same time, Buterin himself wanted to have the hardfork held later - at the end of October, however, due to the upcoming Devcon 3 conference in early November, which is planned to be visited by a large number of developers, these plans were revised.

In the meantime Ethereum developer Hudson Jameson noted that the date of activation of the hardfork is already determined definitively, and can be revised only if there are problems during testing.

The test phase of Byzantium officially started on Tuesday in the test network Ropsten. At the same time, not only the first transaction after the fork was successfully verified, but also the zero-disclosure of zk-SNARK was verified. Thanks to this in the network Ethereum may appear new privacy features, currently found in cryptocurrency like Zcash.

It should be noted that a few days ago the Byzantium was attacked. The attacker filled entire blocks with spam contracts for large sums. Vitalik Buterin, incidentally, called the attack absolutely insignificant.

Ethereum Scaling Solution Raiden to Launch Last Testnet

As noted by the developers, after implementing the new solution, the Ethereum network will be able to provide more than a million transactions per second

On Thursday, July 19, at the Dappcon developer conference in Berlin, the last test network of Raiden for the Ethereum blockchain was launched, CoinDesk reports.

The release includes a minimal implementation of the scaling solution, which will allow the transfer of Ethereum tokens outside of the main blockchain. This is the last test phase before the introduction of technology into the core network of Ethereum.

It's the first step towards going to the mainnet. We really want people to really test this so we have a user interface, we have an API and we've created an open Github for everything they could find, so if we go hopefully bug-free on the mainnet.

Core Developer, Raiden

According to him, the new release represents an early implementation for the core network and contains a new rewritten code of smart contracts and payment channels that can be restored in case of unintended closure.

Also, Karapetsas urged developers to join the test network to help detect possible bugs, adding that a bounty program will be launched to encourage this activity.

The release date for the main network has not yet been assigned, but the developers intend to follow this earlier promise and launch Raiden this summer.

Karapetsas also promised to publish regular updates and code optimizations after the full release, adding that Raiden will complement other Ethereum scaling solutions that are currently being developed.

Raiden is essentially the payment channel network for ethereum, it's supposed to help us scale token transfers. The long term goal would be to have people use Raiden from a mobile device and be able to make off-chain token transfers just from their phone. That would be the long term vision, it would probably work in combination with various scaling solutions, sharding, plasma, a sort of hybrid.

Raiden is developing from the 2015 and is written mostly on Python. The project is much like the Lightning Network. As noted by the developers, after implementing the new solution, the Ethereum network will be able to provide more than a million transactions per second.
