Firo FIRO

Firo is a privacy L1 whose Lelantus Spark construction burns funds and redeems them with one-out-of-many membership proofs (Grootle) plus Bulletproofs+ — modular, auditable, and free of trusted-setup ceremonies, with an anonymity set that spans all previously spent outputs rather than a decoy ring. Selective view keys cover outgoing transactions too, a compliance-friendly property Monero's classic view keys lack. The research bench runs deep: Spats (hiding asset types), Helsing (private staking), Aura (private voting), the Elysium tokenization layer, and FiroDEX atomic swaps. Its history is a curriculum in small-chain survival: a rented-GPU-farm 51% attack that landed weeks before Chainlocks deployed — aimed at forcing exchange delistings rather than theft — and a seed investor who dumped for a year after failing to take over the project. Funding is block reward plus donations; at times the project steward worked unpaid.
