◆ Core Properties 6 invariants · all on-chain

⚒ Supply

Mining + Protocol LP

Miner rewards are emitted by on-chain PoW, while 10% of each miner reward is minted to protocol-owned liquidity inside the same 21,000,000 ANVL cap. No dev premine, no VC tranche.

M(n)=R(n)+0.1R(n), capped by S_max

⛓ Architecture

Zero Backend

This site is static. The CLI talks directly to your chosen RPC. Nothing else is operated — because there is nothing else.

deps = { bytecode, RPC }

◈ Economics

$0.10 Native Fee

Every mine() attaches a $0.10 fee as msg.value. Half goes to the immutable dev recipient; half accumulates for protocol-owned ANVL/WETH liquidity.

fee = $0.05_dev + $0.05_LP

∿ Difficulty

PI + NCT Controller

Proportional-Integral timing control combined with the Nakamoto Coefficient Throttle — difficulty tightens when mining centralises. Decentralisation is a built-in equilibrium, not a social norm.

u[n] = sat(u_pi + u_nct, ±0.5)

◐ PoW

Cascade Keccak-256

Two-pass hash binds each puzzle to live on-chain epoch entropy. Precomputing nonces for a future epoch is structurally impossible — the required value doesn't exist until the previous epoch closes.

κ = H( H(inner ∥ ν) ∥ ε[n] )

✦ Sovereignty

Self-Sovereign

No pool, no registry, no telemetry. One wallet, one GPU, your RPC. Each challenge is unique per miner — reordering txs earns attackers nothing.

advantage(reorder) = 0

◆ Novel Mechanisms 3 results · all formally proven

01

Keccak-Cascade PoW

The puzzle for epoch n incorporates epoch_entropy — derived from the block hash of epoch n−1's confirmed transaction. Since this value is unknowable until n−1 closes on-chain, nonce precomputation and rainbow tables are structurally impossible, not just computationally expensive.

κ = keccak256( keccak256(inner ∥ ν) ∥ ε[n] ) ε[n] = H( b_n−1 ∥ D[n] )

02

Nakamoto Coefficient Throttle

A 256-epoch rolling window tracks distinct active miners. When mining centralises — fewer unique addresses producing the same share of work — difficulty tightens automatically. Decentralisation is not enforced by social consensus; it is the Nash equilibrium.

unct = min( 0.1·(256/Cu − 1), 0.3 ) ≥ 0 minimised (= 0) when C_u = 256 (full distribution)

03

Epoch-Native Schedule

All emission and halving parameters are expressed in confirmed mine() calls — epochs. There are no calendar dates, block time assumptions, or month projections anywhere in the protocol. The next halving is "at epoch 210,000", full stop.

R(n) = R₀ · 2−⌊n/H⌋ S_seed + ∑(R + 0.1R) ≤ 21,000,000 ANVL

◆ Emission Schedule epoch-native · no calendar projections
