Hello all,
Tadge Dryja, Davidson Souza, and I would like to propose 3 BIPs describing
Utreexo, a consensus-compatible (non-soft fork) way to send and verify
transactions without storing the full UTXO set.
The 3 BIPs are for:
1. The specification of the Utreexo accumulator.
2. The specification of Bitcoin block and tx validation using the
Utreexo accumulator.
3. The peer to peer networking changes required to enable Utreexo nodes.
We are currently looking for conceptual review. Do note that the documents
are not final, and they will be updated.
All of the BIPs can be found here: https://github.com/utreexo/biptreexo
We thank you in advance for your time and consideration.
Best,
Calvin
