Building a tiny blockchain
This worries me. Bitcoin solved the double spend problem by using the LCR with PoW. That is the novel aspect which allowed cryptocurrencies to come into existence.If you remove the LCR and PoW, all you are left with is a toy example which cannot work in practice.What is needed is education about censensus design and bitcoin's implementation of the solution, rather than a 'how to guide' for building a basic linked list under the guise of 'blockchain'.Cheers, Paul.
