if you're currently wondering what to do with your life, the answer is almost certainly to build for the solana hackathon

First fork just landed on the #darkdrop repo. @colosseum hackathon teammate onboarded and already studying the frontend flow. Open source privacy protocol with a real contributor now reviewing the codebase. this is how it starts. Two layers of ZK proofs. nine instructions. three circuits. and now more than one set of eyes on the code. github.com/hitman-kai/dar…

Every HIGH and MEDIUM finding is fixed. The credit note model of $darkdrop now has: Zero amounts in claim TX Zero SOL movement in claim TX Zero inner instructions on withdrawal Zero event linkage (M-03-NEW fixed) Zero account data linkage (M-01-NEW fixed with salt) Rug-pull protected (H-01-NEW fixed with obligation tracking) Fee diversion blocked (H-01, M-01 fixed) The protocol is bulletproof on the security side. verify here github.com/hitman-kai/dar…




That's exactly why i built the credit note model from scratch instead of forking an existing mixer. most "privacy" on Solana is the same Tornado Cash architecture repackaged amount visible in the claim TX, Transfer inner instructions on withdrawal, sender wallet exposed on deposit. The credit note model is a different primitive. the claim TX shows zero amounts, zero SOL movement. withdrawal uses direct lamport manipulation, no CPI, no inner instructions for explorers to decode. One more useful unique smart contract for the list. Try it, to know how it works. darkdrop.app Open source github.com/hitman-kai/dar… Check the program on devnet. solscan.io/account/GSig1Q…


I just signed the solana mandate with myself: 200ms blocks 2 slots per leader 300m CUs per second MCP



The fact that the claim tx shows “Unknown” instruction, no amount gets decoded, and there’s no inner transfer is really impressive. The combination of Groth16 + credit note model is pretty smart. I also checked the program IDL even the field names are obfuscated. Solid work @HitmanNoLimit 👏






This is the claim transaction on a privacy protocol i built on $Solana the instruction is "Unknown" — zero decoded amounts, zero SOL transfer instructions. the ZK proof verifies, a credit note is created, and the observer learns nothing. The withdrawal happens in a separate tx using direct lamport manipulation. no system_program CPI. no inner Transfer instruction on any explorer. studied zk-ElGamal, pool-based mixers, Groth16 circuits. combined what i learned into a new pattern. The credit note model. @toly @mert @darkdrop_sol solscan.io/tx/2E8ypV2pHeY…
