About Firo

Firo (FIRO) is a privacy-focused cryptocurrency launched in 2016, originally known as Zcoin. It pioneered the use of zero-knowledge proofs in crypto and has developed several groundbreaking privacy protocols, including Zerocoin, Sigma, Lelantus, and Lelantus Spark, which hides senders, receivers, and transaction amounts. Firo uses a hybrid Proof-of-Work and Masternode security model with ChainLocks to resist 51% attacks, while Dandelion++ conceals transaction IP origins. The ecosystem supports Spark Assets for private token creation and has real-world use, including a blockchain-based political election in Thailand in 2018.
