3-Months full-time software development on monero "core" components in 2021 q1 (through early q2).
## What
Work primarily on the `monerod`, `wallet2`, and `monero-lws` (pending feedback in comments). Some of the work to be attempted or investigated:
- Complete work necessary to merge [DANE/TLSA in wallet2/epee](
- Adding trust-on-first-use support to wallet2 (already work in progress)
- Progress on [my proposal to add encryption to p2p protocol]( has been slow, but it looks like the consensus is FOR encryption, just no clear consensus on TLS 1.3 vs Noise protocol. Continued work would be design+implementation for the selected encryption technique.
- Potential performance improvements:
- Improve "cryptonote" read-serialization performance - helps with p2p block responses, RPC responses, among other things. Profiling suggests this could have big improvement on efficiency.
- Determine a technique for safely returning `std::weak_ptr`/`std::shared_ptr` of p2p connections - this can help with efficiency in a few areas:
- Remove lock acquire to send dandelion++ fluffs and I2P/Tor white noise
- Remove lock acquire and atomic increment per connection when relaying bocks (a list is already obtained)
- Others? Any `foreach_connection` call that can be safely done concurrently can use this technique
- Various epee/p2p serialization (output) routines (carryover from q4, this is difficult to update)
- Potential compilation improvements (carryover from q4 since mj-xmr has focused on this more):
- Moving serialization code to cpp (although this could be spurious in updates which is frowned upon)
- Dropping the templated nature of the epee TCP server would yield best improvement, but might be cause too much "pain" in the review
- `monero-lws` work (assuming no complaints in comments):
- Provide pre-built binaries
- Add support for immediate mempool scanning (via ZMQ-PUB)
- (Unlikely this quarter) - reproducible builds so community members can verify+sign the binary hashes
More than 3 months listed there, priorities may change as community requests or issues arise.
## Who
Lee Clagett (vtnerd). I've had [two]( [CCS]( proposals. The [full list of my PRs for last quarter CCS]( There's also some investigation/writeup for encrypted p2p, and investigations to improve efficiency (logging in particular) that aren't in that list since any code is still a crude mashup for quick testing. A working, but still in progress [DANE/TLSA wallet implementation]( also exists.
Bigger higlights: [improved serialization performance to epee binary](, [removed copy of all outgoing p2p messages and duplicate copies of p2p block notify messages (not merged)](, [changed p2p connection list to `std::weak_ptr` for small efficiency improvement and code clarity (not merged)](, [improved `byte_stream` alllocation efficiency](, [added `byte_stream` realloc to reduce memory usage after new reallocation strategy (not merged)](, and [fixed timeout bug in Dandelion++](
## 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 55 USD/hour with ~197.85 USD/XMR which is the 14-day exponential moving average on Kraken through 2021/02/16.
