Institutional-grade blockchain, engineered for carbon.
COzero is built natively on ZeroChain — a proprietary protocol engineered specifically for mathematically final settlement, compliance-by-construction, and near-zero energy consumption.
Four protocol guarantees that change what carbon trading can be.
Compliance by construction
Permissioning, KYC and reporting hooks are first-class protocol primitives — not bolt-ons. Institutional rails by design.
Six-layer architecture
Settlement, consensus, execution, data, identity and governance — built from scratch, never forked from a public chain.
Near-zero energy
A single transaction consumes less energy than a Google search. Carbon-neutral rails for carbon-credit settlement.
Mathematically final
IBFT 2.0 consensus delivers sub-second absolute finality — eliminating T+2 clearing risk endemic to legacy carbon registries.
The energy case, in watts per transaction.
Logarithmic scale — each gridline is a 10× step. ZeroChain settles a transaction for two-hundredths of a watt.
