Crypto Venture Capital Firm a16z Launches Airdrop Pickup Tool

Crypto venture capital firm a16z launches airdrop pickup tool. Users create a key and a secret, and concatenate hash to create the commitment. The commitment can then be transmitted across a public or private channel without leaking information. An admin assembles a Merkle tree of these commitments and deploys the smart contracts. Users can then redeem airdrop tokens with a zero-knowledge proof that they belong in the Merkle tree without revealing which commitment is associated with their public key.
