Coins: A trustless sidechain protocol

Hi all,

I've been working on a sidechain protocol with no trusted third party. You can find the whitepaper here.

Abstract. 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.

Feedback is highly appreciated!

Thank you

PS: Here on Github you can find further research on scalability and usability

Coinmarketcap are listing BCH sites as BTC

Under here: https://coinmarketcap.com/currencies/bitcoin/ They have links to https://bitcoin.com/ and https://forum.bitcoin.com/ which are no longer BTC sites; they're BCH sites. I'm not good at twitter and don't have many followers but I've tweeted at them here: https://twitter.com/bitplane/status/955918445014585344 Can we raise awareness of this and get them to change it please?

15 years of BTC Power Law

5 years ago I made a post in this subreddit showing that BTC is a power law: Price=A*days^n, (days from Genesis Block), n=5.8. Many didn't believe me and said the past doesn't predict the future. Well, after 5 years it turns out that BTC continues its power law behavior with similar exponent. A power law is not another formula or model but the same mathematical behavior behind river formation, mountains growth, cities development, GDP vs population, and metabolic rate. Everything important is ruled by power laws, so BTC. BTC is a force of Nature.
