Electron Cash: problem found in Bitcoin Cash wallet

Minor problem found with Electron Cash when you first start it

Bitcoin

Is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen

Electron Cash, new Bitcoin Cash wallet released on Monday, 31st of July, is a hardfork of popular Electrum wallet. 

As Bitcoin split really happened yesterday, the users showed an urgent need in Electron Cash. However, as the team reports in its blog, a minor problem was found:

Blockchain

Distributed database that is used to maintain a continuously growing list of records, called blocks

Thus, the problem occurs when Electrum Cash is started for the first time: the thing is that it will follow the wrong chain of the fork initially, the company details. The client is still completely usable, but it requires user action to select the Bitcoin Cash chain after first startup.

According to the report, the problem seems to be that when Electron Cash doesn't find a local blockchain_headers file (which is the case on first start), it tries downloading it via http.

We forgot to change that url so it still points to a file that contains the legacy chain headers. When that file is downloaded, ElectronCash will disconnect from the BitcoinCash chain servers because they don't match what the downloaded file says. It then switches to using legacy electrum servers and verifies the headers and now follows the legacy chain.

Electrum Cash team promises this will be corrected in future versions.

How to fix it?

According to the information provided by the developers' team, right after startup (or any time, really), go to the Network Window (it's reachable from the Tools menu or the Network indicator lamp on the lower right). On the Overview Tab of that window is a server list. If a chain split is detected (which should be the case), the servers are grouped by a branch id. Select the correct branch (the one that has servers electrum-abc.criptolayer.net and electroncash.cascharia.com) by right-clicking on the correct branch id (that long number with the @ sign in it) and select "Follow This Branch" in the popup menu that opens. Vuala, Electon Cash will then follow the BitcoinCash branch of the fork.

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.
