Firo (FIRO)

“Firo, formerly known as Zcoin, is a privacy-focused cryptocurrency that utilizes zero-knowledge proofs which allow users to destroy coins and then redeem them later for brand new ones with no transaction history.

Its research created the Lelantus privacy protocol which supports high anonymity sets without requiring trusted setup and relying only on standard cryptographic assumptions. Firo also utilizes Dandelion++ to obscure the originating IP of transactions without relying on any external services such as Tor/i2P.

Firo developed and utilizes Merkle Tree Proofs (MTP) as its Proof-of-Work algorithm which aims to be memory hard with fast verification to encourage mining using commodity hardware. The blockchain is also further secured with LLMQ ChainLocks, which allow near-instant finality of blocks once confirmed and protect against 51% mining attacks.

Its blockchain was used in the Thai Democrat Party Elections in 2018 to elect its party leader, with over 127,000+ votes cast nationwide, making it the first widescale application of blockchain technology, in a political election.”
