For the past 8 months I've been working on the highlayer project.
It is basically kind-of-rollup (sovereign rollup to be exact) on bitcoin.
Meaning there's 2 ways to include the transaction in network:
- Centralized sequencer
- Bitcoin network
The ability to include transactions through bitcoin network effectively makes it as censorship resistant as bitcoin.
Centralized element, while present and might mess up UX of users by forcing them to submit transaction through bitcoin, won't impact integrity of network: if it double signs or so, network will stop and it will be re-elected through hardfork (and network with faulty sequencer will stay inoperational unless explicitly forgiven by everyone).
It will also have JS as its smart contract lang, so that web2 devs won't need to learn some obscure contract langs.
Here's paper link with more details about its architecture and so: https://highlayer.io/litepaper.pdf
Please tell me the feedback about it in answers to this thread, would appreciate any comments.
