Quick post on a recent whiteboard video from Charles covering side chains and digging into the architecture of Cardano.<\/p>\n\n\n\n
He explores the original essay<\/a> which outlined a settlement layer (essentially Ourobouros which is now in place) with highly secure, reliable and decentralised characteristics, and associated computation layers (or side Chains) which can rely on the settlement layer to provide security but can be customised based on use case.<\/p>\n\n\n\n This approach is needed to circumvent the blockchain trilemma<\/a> (Speed versus Security versus Decentralisation), which due to fundamental limitation of physics and computer science places limits on settlement times assuming you want to maintain a high degree of security and decentralisation (pre-requisites for a layer 1 solution).<\/p>\n\n\n\n Candidates for side chain frameworks include Cosmos<\/a> and Hyperledger<\/a>, with initial applications including World Mobile<\/a>.<\/p>\n\n\n\n
