We propose a strategy to scale Bitcoin to a far greater throughput and performance than available today while keeping the risk of centralization and costs to a minimum. To achieve this we decrease block validation latency with diff blocks, parallelize transaction validation, enable UTXO sharding with transaction input block height annotations, and deploy a series of extension blocks for sustainable capacity increases.
