You can find the [whitepaper here](http://coins.github.io/coins.pdf).\n\nAbstract. Coins is a Bitcoin extension designed for payments at scale. We propose an efficient solution to the double-spending problem using a bitcoin-backed proof-of-stake.  Validators vote on sidechain blocks with one-time signatures, forming a record that cannot be changed without destroying their collateral. Every user can become a validator by locking bitcoins. One-time signatures guarantee that validators loose their stake for publishing conflicting histories. Checkpoints can be additionally secured with a bitcoin-backed proof-of-burn. Assuming a rational majority of validators, the sidechain provides safety and liveness. The sidechain’s footprint within bitcoin’s blockchain is minimal. The protocol is a generic consensus mechanism allowing for arbitrary sidechain assets. Spawning multiple, independent instances scales horizontally.\n\nFeedback is highly appreciated!\n\nThank you\n\n- Robin\n\nPS: [Here on Github you can find further research on scalability and usability](https://github.com/coins/coins.github.io).\n-------------- next part --------------\nAn HTML attachment was scrubbed...\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20200112/10bc934c/attachment.html\u003e"}
