Is blockchain already a deprecated? I just learned about Hashgraph. It seems a very promising evolution of blockchain solving several issues. It promises being able to process several 100'000 transcations per seconds.
Hashgraph with its inventor Leemon Baird claims to have solved the problem of distributed consensus.
Different to blockchain hashgraph is not a chain it is a graph. The graph is build together by adding to every transaction an information of when and from whom the last transaction was recieved (in two hashes) called gossip. This information seems to also include votings of the community about previous transactions so that the current node can come to an consensus without speaking to other nodes (reduces bandwidth massively). (asynchronous byzantine fault tolerance).
Hashgraph promises as well an increase of fairness in terms of order of transactions. In their view blockchain isn't that fair as miners decide which transactions to include into a block and in which order those transactions are in that block. That is a problem in transaction critical use cases e.g. auctions or stock market.
To me this seems to me like a major evolution of the blockchain technology solving major challenges of the current technology. To be honest I don't get it in full yet but I will study hashgraph and share my knowledge as soon as I am up to speed.
For those who want to go also in detail here is a good overview of hashgraph on youtube The Future is not Blockchain. It's Hashgraph.
Have you heard about it before? What are your thought on it?
