I am going to enumerate what I believe to be the ‘First Principles’ of a trustless 2 way peg for a sidechain. If you want to read about current proposals for pegs in sidechains please see my prior blog post.

The goal of this blog post is to create a simple reference for other sidechain developers to reason from when creating their own 2 way peg. I believe these principles hold true for anyone building a ‘trustless’ 2WP.

  1. Merkle proofs must be used for a 2 way peg (OP_WITHDRAWPROOFVERIFY or OP_MERKLEBRANCHVERIFY)
  2. Bitcoin cannot fully validate the sidechain’s consensus rules
  3. Therefore the sidechain to bitcoin peg relies heavily on game theory


The End of Life (EOL) scenario for a sidechain is very interesting. This means that the sidechain is about to die. There are a couple scenarios where a sidechain can die

  1. The sidechain was such a success and…

Sidechains are some of the most interesting technical proposals in the blockchain space. A sidechain allows you to use a blockchain’s token as the underlying asset for another blockchain. An example of this could be using bitcoin as the underlying asset for big block version of bitcoin. This means we…

When ethereum developers figured out that the DAO — a project whom they…

Hard forks have been a hot topic in Bitcoin recently, and I want to try and make sure non technical people understand the implications of a hard fork. This blog post builds off of this previous blog post:

First off, consensus rules are equivalent to unalienable rights. By running a…

As everyone in the Bitcoin space knows, there is a massive scaling debate going on. One side wants to increase the block size via segwit, while the other side wants to increase the via hard fork. I have strong opinions on the topic but I won’t discuss them here.
