Vitalik Buterin, co-founder of Ethereum, introduced a blockchain scale solution called Plasma Cash, an even more scalable version A solution called Plasma, at a conference broadcast live on YouTube at the Ethereum Community Conference in Paris on Friday, March 9th.

Plasma Cash was developed by Buterin and developers Dan Robinson and Karl Floersch

Plasma itself is a scaling solution in chain for Blockchains, introduced by the creator of Buterin and Lightning Network, Joseph Poon, in August 2017. Plasma works by optimizing the data transmitted to the Blockchain root, reducing transaction costs for smart contracts and decentralized applications.

The problems of scalability of plasma, according to Buterin, are that each user must download and authenticate each plasma block, which prevents

To explain the Plasma Cash model, Buterin gives the example that if a user deposits a certain amount of ether at an encryption exchange or at a third party service, a piece of plasma would be created with the same value of and unlike plasma, Plasma cash would only ask for users to pay attention to blocks that contain parts they want to keep track of:

] "A user only needs to check the availability and accuracy of the Plasma chain only […] at the specific index of the coin, all the coins they own and coins they care about. "

With regard to the actual practical applications of Plasma Cash, Buterin sees a possibility for cryptographic exchanges to take advantage of technology to become more "pirate-resistant".

Since each plasma room has an owner, the rooms are not fully fungible or interchangeable: no one can take another user's room without the owner of the room being alerted. In this case, the owner of the coin would prevent the potential fraudulent withdrawal through the "Complaint System" by showing their "Evidence" for the history of their coin.

Buterin notes that even if hacking occurs on an exchange using Plasma Cash, users will not lose their money:

"No matter what happens in the # 39, exchange, users can use their money to get their money out. "

Buterin ends his speech with a positive prognosis for the future use of Plasma Cash:

"Whenever the next big multibillion-dollar exchange written by a totally incompetent developer is hacked, no one will lose money."

Segregated Witness (SegWit), a Scalability solution for Bitcoin (BTC), has recently been implemented across a variety of crypto exchanges. The Bitfinex Exchange announced the implementation of SegWit on February 20th, and the crypto exchange and Coinbase Portfolio announced their SegWit implementation on February 23rd. The Bitcoin Core client version, which fully supports SegWit technology, was officially launched on February 26th.
