βScaling and anonymizing Bitcoin at layer 1 with client-side validationβ - our new proposal, also sent to bitcoin-dev mail list.
https://github.com/LNP-BP/layer1
βWe propose a way to upgrade Bitcoin layer 1 (blockchain/timechain) without a required softfork. The upgrade leverages properties of client-side validation, can be gradual, has a permissionless deployment option (i.e. not requiring majority support or miner cooperation) and will have the scalability sufficient to host billions of transactions per second. It also offers higher privacy (absence of publically available ledger, transaction graphs, addresses, keys, signatures) and bounded Turing-complete programmability with a rich state provided by RGB or another client-side-validated smart contract system.β
