In other words, PadLock uses Secret Contracts to enable programmatic contract interactions that unlock access control via decryption of viewing keys. Secret Non-Fungible Tokens (NFTs) will allow for the creation of NFTs that have verifiable ownership of goods and experiences without ever exposing the underlying owner or their data – all made possible with Secret Contracts. Secret Automated Market Makers (AMMs) will help prevent front-running, a problem that has plagued DeFi since its inception. Due to the public nature of blockchains, front-running attacks happen all the time.
