+## What
+
+Work full-time 3 months on:
+
+- Integrating [full-chain-membership proofs](https://ccs.getmonero.org/proposals/fcmp++-development.html) into Monero under RingCT.
+  - As part of this CCS, I will submit PR's to the core Monero repository that do the following:
+    - Implements the tree in C++ described in section 6.1 ([paper](https://github.com/kayabaNerve/fcmp-ringct/blob/develop/fcmp%2B%2B.pdf), [reference commit](https://github.com/kayabaNerve/fcmp-ringct/blob/221e8c0e155d5fe526080c6e56c6418e0433177d/fcmp%2B%2B.pdf))
+      - Implements the `grow` and `trim` algorithms (sections 6.1.1 and 6.1.2)
+    - Implements tree initialization with existing cryptonote outputs on boot (section 6.2.1)
+    - Implements growing the tree as the node syncs (section 6.2.2 and 6.2.3)
+    - Implements the transaction class containing FCMP's (part of sections 6.3 - 6.6)
+      - I will probably extend `cryptonote::transaction` to do this.
+  - The following tasks from the rest of section 6 are necessary to complete the integration; I'm happy to divide and conquer if someone wants to work on this as well:
+    - Implement transaction construction with FCMP's (sections 6.3 - 6.6)
+      - A pre-requisite for this is implementing the transaction class above.
+    - Implement transaction verification (section 6.7)
+    - Implement RPC route to return a path for outputs (section 6.9)
+    - Implement unifying the distribution of {coinbase, pre-RCT, RCT} outputs and use it to select decoys paths (section 6.10)
+    - Implement changes for multisig (section 6.11)
+- Continuing Seraphis wallet library work.
+  - My next task on this front is to bring the Serpahis lib async scanner into the current wallet API.
+    - To be clear, this is not implementing the Seraphis upgrade; it is bringing the Seraphis wallet **library**, which supports scanning today's blockchain, into the core Monero repository. This would speed up wallet scanning **today**, and is part of an effort to deprecate wallet2 and its technical debt, and replace it with the Seraphis lib ([source](https://github.com/seraphis-migration/wallet3/issues/64#issuecomment-2067030930)).
+    - The async scanner is currently under review ([source](https://github.com/UkoeHB/monero/pull/23))
+    - In the latest round of benchmarks, I observed scanning speed-ups of 50-60% with a clearnet remote node, 40-45% with a tor node, 25-35% with a local node, all running the **current chain** (not Seraphis).
+    - To be usable in the wallet API today, the following still needs to be implemented (I'm also happy to divide and conquer here):
+      - Pre-RCT index handling (needs [source](https://github.com/UkoeHB/monero/pull/23))
+      - A mutable subaddress lookahead ([source](https://github.com/UkoeHB/monero/pull/23#issuecomment-2036086371))
+      - Pool scanning ([source](https://github.com/UkoeHB/monero/issues/41))
+      - A clean way to save tx metadata ([source](https://github.com/UkoeHB/monero/issues/48))
+- Complete p2p SSL review ([source](https://github.com/monero-project/monero/pull/8996)).
+- Misc. review, debugging, etc.

+## Proposal
+
+376 XMR
+
+480 hours, 0.25 XMR/hr + $65/hr, $122/XMR from coingecko
+
+I'm requesting a siginificant raise from my past CCS (0.16 XMR/hr -> 0.25 XMR/hr, $48/hr -> $65/hr) because I believe I have demonstrated improved performance, and believe the recent donations to CCS proposals demonstrate the community is capable of paying strong Monero contributors market / above-market rates. I believe paying market / above-market rates for strong contributors is a stronger strategy for Monero to attract and retain strong talent.
