The main blocker (sic) at the moment is that current decentralised finance technology (DeFi) that powers blockchain implementations require environmentally wasteful mining algorithms to ensure trust in the decentralised ledgers that make up the blockchain. This ‘proof by work’ approach is currently being evolved into a ‘proof of stake’ approach at the expense of a fully decentralised model, with the latter considerably less energy wasteful.
