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.
