Blockchains operate as a public ledger, ‘disclosing’ the entire transaction history and associated data to everyone. While verifiability and traceability are key traits, as blockchains gain global adoption, those very features hinder the process. Self custody, on-chain identities, corporate strategies, transaction history, private deals, all represent highly sensitive information that call for provable confidentiality. Fully homomorphic encryption has long been considered the ‘holy grail’ of cryptography as it enables computation to be performed on encrypted data without the need of prior decryption. This basically translates to true end-to-end encryption, both on-chain and off-chain. As cryptographic research advances, so does the scalability and applicability of FHE. As a result of more than 5 years of work, Zama has now released Zama Protocol, which enables confidential smart contracts on top of any L1 or L2 using FHE, without any additional execution burden. By encrypting all ciphertexts with the same public key, FHE ensures composability and seamless integration across different blockchains and applications, making it a true cross-chain confidentiality layer. Through parallel execution, Zama Protocol already surpasses Ethereum’s throughput, yet future roadmap includes open-source development of FPGA & ASIC in order to scale it even further, to accommodate faster, non-EVM chains.
