3-Months full-time software development on monero "core" components in 2025 q1/q2.
## What
Work primarily on `monerod`, `wallet`, and `monero-lws`. Some of the work to be attempted or investigated:
- Code reviews of monero core PRs
- monerod/monero-lws bug fixes and HackerOne mitigations as they arrive
- Keep existing PRs up-to-date:
- New Serialization routine
- Change from raw pointers to weak_ptrs in levin code
- Socks v5
- P2P SSL Support
- Updating levin callbacks to C++14 moves
- Embargo timeout fix
- Find (possible) memory leak in weak_ptr PR
- Complete work necessary to merge [DANE/TLSA in wallet2/epee](https://github.com/vtnerd/monero/tree/improve/dane_tlsa).
- Adding trust-on-first-use support to wallet2
- Add msgpack support to monerod-ZMQ (requires merging of new serialization system)
-`monero-lws` work:
- Determine a “push” interface for LWS clients (instead of existing poll interface)
- Complete LWS frontend (using `wallet_api.h` as interface) so that wallets can begin using LWS API easily. This is separate from woodser et al working on LWS API within `wallet2` which may be deprecated.
- Add a new utility (to LWS-frontend) that accepts a spend key to report balance+spent transactions of wallet (requested via Github Issues). This will help verify accuracy of LWS endpoints
- Update LWS spec and implementation to support new "carrot" features (view-balance key, etc)
- Update LWS backend to work with fcmp++ experimental branch
- Add a "scale" factor to remote scanning load balancing - send more accounts to systems with faster single thread performance
- Add 64-bit ed25519 code for faster arm64 scanning
- Provide official LWS docker-image
- Provide pre-built binaries
- (Unlikely) - reproducible builds so community members can verify+sign the binary hashes
There is intentionally more work than time allows - to ensure there is always something to work on in the proposal.
## Who
Lee Clagett (vtnerd). I've [had](https://ccs.getmonero.org/proposals/vtnerd-tor-tx-broadcasting.html)[five](https://ccs.getmonero.org/proposals/vtnerd-2020-q4.html) [CCS](https://ccs.getmonero.org/proposals/vtnerd-2021-q1.html), [proposals](https://ccs.getmonero.org/proposals/vtnerd-2023-q3.html)([last one](https://ccs.getmonero.org/proposals/vtnerd-2024-q3.html)), and [one Magic Grant](https://monerofund.org/projects/Q1Q2_2024_dev_vtnerd).
Some of my biggest features in monero core repo are [Dandelion++](https://github.com/monero-project/monero/pull/6314), [adding supercop ASM speedups to wallet code](https://github.com/monero-project/monero/pull/6337), [ZeroMQ Pub Support for new blocks and transactions](https://github.com/monero-project/monero/pull/6418), and [SSL support to p2p](https://github.com/monero-project/monero/pull/8996).
I've also made a functional LWS wallet scanner under CCS/Magic - which now has a MyMonero compatible REST API (now fully non-blocking to support more responses per thread), admin REST API, LMDB storage, subaddress support, webhook/zmq/rmq publishing (new receives, spends, and accounts), multi-machine scanning with (primitive) load-balancing, and an untrusted daemon mode that verifies PoW is valid (whereas normal wallets trust `monerod` responses entirely).
## Proposal
Work on the various tasks outlined above for 40 hours/week over the next 3 months after potential funding. I already use time-tracking software for work; if the hours dip in a given month unexpectedly, the update/milestone will be at the completion of the hours listed above.
The funds were calculated with 65 USD/hour with ~232.20 USD/XMR which is the 14-day exponential moving average on Kraken through 2025/02/21.
