Twelve terms that explain chain 2800, each grounded in a measurement you can re-run yourself.
- Post-Quantum Anchor
Every 32nd block header on chain 2800 binds a Falcon-512 validator certificate under the block hash via a 32-byte digest, live since block 13,014,000. - Validator
A validator is one of nine nodes that propose and sign blocks on chain 2800, where a block becomes final once six of them have signed it. - Finality
On chain 2800 a block is final the instant six of nine validators commit it under QBFT, so finality arrives with the block itself, in about half a second. - Precompile
A precompile is a native function at a fixed address; on chain 2800, five post-quantum signature verifiers have run this way since block 9,189,161. - QBFT Consensus
The vote-based consensus behind chain 2800: nine validators, a quorum of six, one block roughly every 500 ms, and finality the moment a block appears. - Falcon-512
The lattice-based signature scheme, selected by NIST for post-quantum standardization, that chain 2800 uses to anchor its block history. - Seal Certificate
A bundle of Falcon-512 validator signatures over a block, with a 32-byte digest sealed under the block hash on every 32nd header of chain 2800. - Base Fee Floor
A consensus-enforced minimum base fee: chain 2800 rejects any block header whose base fee falls below the floor, keeping spam costly and fees predictable. - Block Header
A block header is what the block hash commits to; on chain 2800 every 32nd header since block 13,014,000 also binds a post-quantum certificate digest. - Signer Registry
The on-chain list binding each of chain 2800's nine validators to a Falcon-512 public key, committed as a keccak digest in an immutable contract. - Client Diversity
Two independently written clients validate chain 2800, so a bug in one implementation becomes a visible disagreement instead of a silent network-wide fault. - EVM Compatibility
Chain 2800 runs the standard EVM: Ethereum contracts and tooling work unchanged; post-quantum additions live in precompiles and the header, not the EVM.
