Some of free time (not much time) projects:

• go-snark: Go zkSNARK implementation from scratch
• go-bellman-verifier: Go Groth16 zkSNARK bellman proof verifier using cloudflare/bn256 Pairing
• babyjubjub-rs: BabyJubJub elliptic curve implementation in Rust
• poseidon-rs: Poseidon hash implementation in Rust
• go-blindsecp256k1: Blind signatures over secp256k1 in Go (With the compatible Typescript version)
• go-dht: Kademlia DHT implementation in Go
• merkletree-rs: Sparse MerkleTree implementation in Rust
• go-merkletree: Sparse MerkleTree implementation in Go
• shamirsecretsharing: Shamir's Secret Sharing Rust & Go implementation + WASM lib
• cryptofun: Crypto algorithms from scratch, in order to get familiar with them from inside. For example: ECC, Paillier, RSA, Homomorphic computation, ElGamal, Schnorr, ECDSA, BN128, BLS, ...
• commonroutes: A car sharing smartphone app + server + bots, etc
• flock-botnet: A twitter botnet with autonomous bots replying tweets with text generated based on probabilities in Markov chains in Go
• blogo: Static blog generator, templating engine from markdown and html templates (what I use for my blog)
• coffeeminer: collaborative (mitm) cryptocurrency mining pool in wifi networks
• kvartalo: a local social cryptocurrency for neigbourhoods, that we are using in a Barcelona neighbourhood as experiment. Build on top of Ethereum blockchain & Tendermint Core
• go-chip8: CHIP-8 emulator written in Go
• chip8-rs: CHIP-8 emulator written in Rust
• fft-rs: Fast Fourier Transform (FFT) implementation in Rust
• miksi: Ethereum zk-coin-mixer where all the computation & constructions are done offchain and then proved inside a zkSNARK to the smart-contract. (live demo on testnet)

Some repositories done while working at iden3 and Hermez zkRollup:

• iden3/go-iden3-crypto: Go implementation of some cryptographic primitives (that fit inside the SNARK field) used in iden3
• iden3/go-iden3-core: Go core implementation of the iden3 system
• iden3/go-circom-prover-verifier: Go implementation of the Groth16 zkSNARK Prover and Verifier compatible with Circom
• iden3/circuits: circom zkSNARK circuits used by the iden3 core protocol
• hermeznetwork/hermez-node: Go implementation of the Hermez zkRollup node.
