Dear list,

In previous arguments over Drivechain = (and Drivechain-like proposals) I promised that better scaling proposals = =E2=80=94 that do not sacrifice Bitcoin's security =E2=80=94 would come = along.

I = planned to do a detailed writeup, but have decided to just send off this = email with what I have, because I'm unlikely to have time to write up a = detailed proposal.

The idea is very simple (and by no means novel*), and I'm = sure others have mentioned either exactly it, or similar ideas (e.g. = burning coins) before.

This is a generic sharding protocol for all blockchains, = including Bitcoin.

Users simply say: "My coins on Chain A are going to be sent = to Chain B".

Then they burn the coins on Chain A, and create a minting = transaction on Chain B. The details of how to ensure that coins do not = get lost needs to be worked out, but I'm fairly certain the folks on = this list can figure out those details.

- Thin clients, nodes, and miners, can = all very easily verify that said action took place, and therefore accept = the "newly minted" coins on B as valid.
- Users = client software now also knows where to look for the other coins (if for = some reason it needs to).

This doesn't even need much modification to the Bitcoin = protocol as most of the verification is done client-side.

It is fully = decentralized, and there's no need to give our ownership of our coins to = miners to get scale.

My sincere apologies if this has been brought up before (in = which case, I would be very grateful for a link to the = proposal).

Cheers,
Greg Slepak

* This idea is similar = in spirit to Interledger.
