Buterin Needs Bitcoin Cash: Scaling Ethereum Before Sharding, Casper

Co-founder of Ethereum Vitalik Buterin is now considering third-party blockchains that have lower commission rates for transferring information.

"In the long-term we expect that the data layer for these schemes to be Ethereum 2.0 itself. Until Ethereum 2.0 exists what you have is first of all the existing Ethereum chain but the existing Ethereum chain is already basically 100% full and it has been full for a while. And we could do marginal things to increase its scalability but it's still relatively expensive and so there's other strategy you could consider. To do some short-term things is basically to just use these second-tier blockchains as extra data layers."

Erin brings Bitcoin Cash into the discussionButerin explained his choice of the BCH blockchain because of its optimal throughput of 53 KB per second, which is almost seven times higher than that of Ethereum.

"You have a computation layer from Ethereum side and a data layer from BCH side. Symbiosis where there can be offloading of data from Ethereum into Bitcoin Cash.".

As claimed by the founder of Ethereum, the network already has the necessary mechanisms for verifying Bitcoin Cash blocks, with BTC Relay being an Ethereum contract that stores Bitcoin block headers.

Finally what makes BCH attractive as a scalability solution for Ethereum is what Buterin calls the positive attitude of the BCH community toward "People using their chain for whatever they want as long as they pay the tx fees."

Any alternatives for Ethereum?As an alternative, Ethereum founders are also considering Ethereum Classic, where the block confirmation time is 14 seconds.

The only issue that needs to be resolved to work with the ETC blockchain is the lack of reliable applications on the Ethereum platform confirming the block verification on the ETC blockchain.

Judging by the statistics presented on the website crypto51.com, one hour of attack on the Bitcoin Cash blockchain would cost a hacker around $20,000, while for Ethereum this, figure would be $120,000.

Back in June, another Ethereum co-founder, Joseph Lubin, claimed that Ethereum has "already scaled quite significantly.
