Core engineering and protocols for Threshold Lattice MPC Custody.
Traditional crowdfunding platforms and financial escrow services store master private keys in centralized hardware security modules or single-signature cloud wallets. If a rogue administrator, compromised API credential, or quantum adversary accesses the private key, hundreds of millions of dollars in investor capital can be transferred in a single transaction.
CrowdfundingVault implements threshold post-quantum digital signatures based on FIPS 204 ML-DSA. The signing key never exists in any single location: it is mathematically partitioned across independent nodes operated by the platform, an independent escrow agent, and a regulated bank. A transaction is valid only when a quorum cooperatively generates a joint signature.
