Architecture — Fibonacci

Technical Architecture

A modular Layer 1, engineered for machines.

Fibonacci composes five layers under a single security domain. Each layer is independently upgradable, formally specified, and benchmarked against adversarial conditions.

Layer 1 · Consensus

φ-BFT — Phi Byzantine Fault Tolerance

A deterministic HotStuff-derived consensus with two innovations: golden-ratio leader rotation (validators are scheduled on a Fibonacci-distributed slot schedule that minimizes adversarial collusion windows) and pipelined three-phase commits achieving 0.382s finality at 12,800+ validators.

Sybil resistance comes from stake + reputation hybrid weighting. MEV is neutralized at the protocol level via encrypted mempool (threshold BLS) + sealed-bid block auction.

// φ-BFT round, simplified


round  t        leader = validators[fib(t) mod n]
phase  prepare  leader → broadcast(block, qc_{t-1})
phase  precommit  ⅔+1 validators → sign(prepare)
phase  commit    ⅔+1 validators → sign(precommit)
finality  ≈ 382ms median
                  ≤ 600ms p99
liveness  guaranteed under partial synchrony (Δ=2s)
safety    holds while < ⅓ validators byzantine

Layer 2 · Execution

Parallel EVM++

Optimistic parallelism

3 shards

Block-STM scheduler runs non-conflicting transactions concurrently across three execution shards. Median speedup: 14×.

EVM++ opcodes

EIP-φ

Adds INTENT, AGENT_AUTH, VERIFY_INFERENCE, and STATE_RENT opcodes. Full Solidity backward compatibility.

Multi-VM

WASM · Move

Run Solidity, Rust (WASM), or Move contracts in the same block. Inter-VM calls settle atomically.

Layer 3 · Agent Runtime

Native intelligence at the protocol level

Identity

ERC-φ standard. Every agent has a DID, key rotation, capability tokens, and a reputation score derived from on-chain history.

Memory

Encrypted long-term memory anchored on-chain, contents stored on ZK-DA. Retrieval by content hash + ACL.

Intents

Declarative transaction language. Solvers compete to execute under user-set constraints. Built-in MEV redistribution.

Verifiable Inference

zkML co-processor produces succinct proofs that an off-chain model output was honestly computed.

Layer 0 + Security

Data availability and cyber-defense

ZK-DA

A KZG-commitment data availability layer with erasure coding. Compresses agent telemetry by 94% versus calldata. Bridge proofs verify in 38ms on Ethereum mainnet.

·KZG polynomial commitments
·Reed-Solomon 2D erasure (128×128)
·Data sampling: 16 chunks for 99.99% availability
·Cross-chain bridges: ETH, Solana, Bitcoin (via tBTC), Cosmos
