Subject: [bitcoindev] Utreexod beta release

Hi all,

Utreexod, a full node implementation with Utreexo accumulator support, is 
now
available for general testing by the public. Notable features are:

- Implementation of efficient Utreexo accumulators with an improved deletion
  algorithm from the Utreexo paper.
- Efficient P2P transaction relay with support for caching utreexo proofs 
for
  mempool transactions.
- Quick sync to the tip of the blockchain with AssumeUtreexo.
- Built in wallet support (with BDK wallet).
- Electrum personal server support for usage with other wallets.
It’s important to note that the code and protocol is not peer reviewed. 
Using
the node for production usage or for non-negligible amounts of Bitcoin is 
not
recommended. There will also be breaking changes requiring frequent updates 
as
well. Utreexod is also based off of btcd 
(https://github.com/btcsuite/btcd), a
bitcoin node implementation in Go. Because of this, there may be consensus
incompatibilities either as a result of a btcd bug or a Bitcoin Core bug.

Also note that there are not many Utreexo nodes on the network. It may take 
a
while for the node to find a Utreexo node it can sync off of. To help 
bootstrap
the network, consider running an archival node or a bridge node. Refer to 
the
readme on the github (https://github.com/utreexo/utreexod) page for 
instructions
on how to run a bridge node or an archival utreexo node.

Prebuilt static binaries for Linux, MacOS, and Windows are available at
(https://github.com/utreexo/utreexod/releases/)

Huge thanks to HRF for funding my work for this release. Without the 
support I
wouldn’t have been able to focus on Utreexo.

Also thanks to all the folks that directly contributed to the release:
