Buterin to Demand Court Challenge Against nChain Patent

Ethereum founder openly criticized the latest patent of the research company nChain and called for its annulment in court

NChain, whose chief researcher Craig Wright had previously stated that he was the creator of Bitcoin Satoshi Nakamoto, while actively promoting Bitcoin Cash, received the latest patent in Europe for "invention in the field of digital security". This is reported by Bitcoinist.

This Deterministic Key Generation technique provides for improved secure communication between a pair of nodes or parties on a network, while being able to keep their private keys secret.

nChain is trying to create a set of tools on the blockchain to carry out cross-border transfers through the so-called "Internet transactions".

Wright's company continues to attract attention due to ambiguous marketing decisions. Last month, at a conference in Rwanda, Wright told the audience that "he has more money than the whole of their country."

This looks like they're trying to patent plain old public master key-based deterministic wallets, like what we had in 2013. Can't someone attack it in court with the obvious mountains of prior art?

In the past, Buterin repeatedly accused Wright of fraud.

Describing the possibilities for applying the present invention, nChain CEO Jimmy Nguyen said that their technology has been recognized by the Japanese technology conglomerate SBI.

We Need 100k Transactions\Sec, - Buterin

During the conversation with the head of Abra Vitalik noted that the developers are focused on several main issues - scalability, privacy and ease of use

The founder of Ethereum, Vitaly Buterin, expressed the opinion that for the network of the second most capitalized cryptocurrency, it is vital in the long run to achieve a throughput of 100 thousand transactions per second. It is reported by The Daily Hodl.

During the conversation with the head of Abra, Bill Barkhidt, Vitalik noted that the developers are focused on several main issues - scalability, privacy and ease of use.

As far as the big problems, my top three at this point are probably scalability, privacy and usability. So scalability – the Ethereum blockchain right now can process 15 transactions per second. Really, we need 100,000.

According to him, in the context of solving the problem of scaling, the Ethereum team has high hopes for sharding.

There are two major kinds of strategies that we’re working on for scalability. One is layer-one scaling and the other is layer-two scaling. Layer-one scaling basically means improving the blockchain protocol itself to process a larger set of transactions. And the main bottleneck with blockchains right now is basically every user has to download the whole blockchain. Which basically means the blockchain can’t hold more transactions than one guy’s computer can store.

And our solution to this, called sharding, basically means that you split up the different transactions to randomly selected, different groups of computers. And this basically means that the blockchain can process way more things than one single computer can hold. And that can increase scalability by maybe a factor of 1,000 or so, but then potentially even more, much later down the road

According to Vitalik, Ethereum developers also continue active work on second-level scaling solutions.

So there’s two major classes of systems we’re working on in this regard. One is called state channels. And there’s a bunch of teams working on this. There’s a team called L4 in Toronto that’s done some really good work. And another project is Plasma. And there’s a lot of work that’s been done on that. OmiseGo is this decentralized exchange that’s building on plasma. There’s TheMatter. There’s more and more of these projects. And then, there’s one of our researchers, Karl Floersch, who has been working on implementation of a reasonably complete Plasma prime specification, which is the latest version of Plasma – which has some really cool features in terms of increasing scalability and reducing the amount of data you have to store.

Discussing the problem of scaling, Buterin mentioned Bitcoin. According to him, developers should achieve a significant increase bandwidth of Ethereum network. Otherwise, the second cryptocurrency capitalization will not be actively involved in everyday transactions and a significant market share will remain behind BTC.

If Bitcoin wishes to just be a store of value, then realistically it’s probably fine, though I think they should switch to proof-of-stake. If they want to actually be a currency that people use for transactions, then I do think base-layer scaling, and also speeding up the blockchain and reducing block times at the base layer, is also something which is very important.
