Lava is a UTXO-based PoC consensus public chain project. The mainnet was launched on August 28, 2019. The Firestone mechanism is a unique sub-layer (Sub-Layer) certificate for Lava. You can obtain Firestone by mortgaging LV tokens to the system, and get double block rewards when blocks are produced in the next cycle. In terms of storage, it pioneered the PoC2+ standard and is expected to implement PoC3 next year. At present, the "confidential asset" technology has been added, and it has become a project that combines "PoC+CA+UTXO" to realize the issuance of private assets and develop towards De-Fi.
