Bitcoin Cash emergency difficulty adjustment

Bitcoin Cash emergency difficulty adjustment may take place as no blocks mined for some hours

Bitcoin Cash, the brand new cryptocurrency emerged as the hard-forked version of Bitcoin, after reaching its all-time high price mark of more than $900 and being finally supported by the leading cryptocurrency exchanges, pools and wallets, now seem to be experiencing some mining troubles. 

Thus, Charlie Lee, the Litecoin creator and an active Twitter user also known as one of the most honest developers in the cryptocurrency world, reports on 2.5 hours without single Bitcoin Cash block being mined and expresses his scepticism about the future success of the cryptocurrency:

It's noteworthy, that a bit earlier, on August 21st, the man shared his predictions about Bitcoin Cash mining difficulties:

Jeff Garzik, a former Bitcoin Core developer, objected that, in his opinion, "this is a short term oscillation generated by profit-switching pools; occurs w/ litecoin, dogecoin, eth/etc & others". However, the creator of Litecoin hastened to remind Garzik about the Namecoin story:

Just like what happened with Namecoin in 2011. "Those who do not learn history are doomed to repeat it."

Thus, according to Jimmy Song, one of the Bitcoin developers, new difficulty adjustment is to take place:

What the future has in stock for the cryptocurrency, remains to be seen. At the time of writing, Bitcoin Cash price is about $658 and it's market capitalization is almost $11 billion (however, less than the 3-rd ranked Ripple's). 

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.
