Cuprate is a WIP Rust Monero node that SyntheticBird45 started back in Feburary, I joined the project not
|
|
long after that, but sadly me and SyntheticBird have not been able to spend much time on it. Even more sad
|
|
is that recently SyntheticBird decided to stop working on Cuprate for personal reasons that I will not get
|
|
into here.
|
|
|
|
This CCS is to support me working on Cuprate full time for the next 2 months, In this time I will complete
|
|
the transaction/ block verification. While doing this, I will also create a `consensus rules` document, which
|
|
will document all of Moneros consensus rules from genesis to the current rules.
|
|
|
|
# Why
|
|
|
|
Currently, Monero only has one node written in C/C++, many would see this as an issue.
|
|
Having only one implementation makes us more vulnerable to implementation bugs, having
|
|
another node will help us to spot and fix these issues.
|
|
|
|
monerods code is also a bit of a mess, as many devs who have worked on it would agree. Cuprate
|
|
is a fresh start and is built with modularity in mind which will lead to a cleaner and easier
|
|
to understand codebase.
|
|
|
|
Having a `consensus rules` document will make it easier for developers to build software to interact
|
|
with Monero. It will also make it easier to spot potential issues with consensus rules.

# Who
|
|
|
|
I am [Boog900](https://github.com/boog900), the current, and now solo, maintainer of Cuprate.
|
|
|
|
# Design
|
|
|
|
For an overview of the design see [here](https://github.com/Cuprate/cuprate/blob/main/misc/DESIGN.md)
|
|
|
|
# What Has Been Done
|
|
|
|
## P2P
|
|
|
|
The peer-to-peer code is mostly complete; I have implemented levin headers, the epee binary format and all p2p messages.
|
|
I have also done the p2p address book, individual peer request routing, handshakes and pruning calculations.
|
|
|
|
## Blockchain Data
|
|
|
|
I made a PR to monero-serai adding decoding/encoding/hashing of legacy transactions and blocks so this is complete.
|
|
|
|
## Consensus Checks
|
|
|
|
There is still a lot to do here, but monero-serai has already done verifying for bulletproofs(+) and CLSAG.
|
|
My PR to monero-serai also contained an unverified MLSAG verify function and a WIP Borromean range proofs
|
|
function.
|
|
|
|
## Database
|
|
|
|
The initial database abstraction is complete, and we have defined the tables (we have copied monerod for
|
|
the moment). We have also created the methods to add and get blocks and transactions from the database.
|
|
|
|
Still to-do: We need to investigate the database schema for optimizations.
|
|
|
|
# Tasks
|
|
|
|
We need to implement/ get ready for production verifying for MLSAG, borromean range proofs and V1 ring signatures, there are other
|
|
checks we need to do, but these are the big ones. As Monero does not have a protocol document, we will have to go through monerod
|
|
to find every check it performs and do them in Cuprate.
|
|
|
|
Cuprates consensus checks will be grouped together in a single location, so they are clear and not spread around the codebase,
|
|
they will also reference the `consensus rules` document at every check. If some checks are done elsewhere, for example some are done at
|
|
deserialization, we will either duplicate the check or, if its expensive, we will put a comment referencing the check and the
|
|
`consensus rules` in the single location.
|
|
|
|
We also need to create bindings for Moneros legacy CryptoNight POW algorithms and select a Random-X binding. There is a Rust
|
|
Random-X implementation, which we plan to implement as an option, but we won't enforce it as it lacks review/ usage.
|
|
|
|
As our P2P/ database code still needs some work, we will be using monerods RPC interface to test the code.

### Milestones
|
|
|
|
1. ###### All Consensus rules up to RCT
|
|
Implement verification for transactions and blocks before RCT.
|
|
2. ###### All Consensus rules up to present
|
|
Implement verification for all transactions and blocks.
|
|
3. ###### Creation of the `consensus rules` document

# Funding
|
|
|
|
I am asking for $45/hr for 50hrs/week for 2 months at $148/XMR this gives 130 XMR
