-  Tezos is a self-amending proof-of-stake blockchain using Liquid Proof of Stake (LPoS) and an on-chain governance mechanism that allows protocol upgrades without hard forks. It targets roughly one block every 30 seconds on mainnet. Public REST endpoints are available without an API key from SmartPy, TezBeta and TzKT (Baking Bad). Every provider was live-verified with consecutive block header probes at launch.
