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.<p>If you remove the LCR and PoW, all you are left with is a toy example which cannot work in practice.<p>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'.<p>Cheers, Paul.
