Zama is an open-source cryptography company dedicated to building state-of-the-art fully homomorphic encryption (FHE) solutions for blockchain and artificial intelligence, and is a leader in the FHE field. The Zama protocol ensures confidentiality at any L1 or L2 level. Zama uses fully homomorphic encryption (FHE) to ensure that on-chain data is always encrypted, even during processing. It is scalable, secure, and affordable. Zama uses coprocessors to offload FHE computations from the base chain. This maintains low gas costs while enabling horizontal scaling and public verifiability. Fully homomorphic encryption (FHE) is an advanced cryptographic technique that allows computations (such as addition and multiplication) to be performed directly on encrypted data without first decrypting it. The result, after decryption, is identical to the result of performing the same operation on plaintext. Data remains encrypted throughout the computation process, making it suitable for scenarios requiring high privacy protection, such as cloud computing, medical data analysis, and financial transactions.
