Brief Whitepaper
Chipcoin combines Proof of Work with native on-chain rewards for verified nodes.
The current public testnet already runs the full stack: node, external miner, browser wallet, faucet, explorer/API, snapshot bootstrap, and a native Node Rewards loop operating on public testnet. Chipcoin's core public claim is that it is building the first native decentralized PoW protocol that also pays verified nodes, not only miners.
Abstract
Chipcoin is a decentralized PoW protocol that also allocates programmed emission to verified nodes.
Bitcoin pays miners. Chipcoin keeps PoW mining, but adds a native reward path for verified nodes. Those rewards are not extra inflation. They are part of the programmed emission model and settle on-chain at epoch close.
The live public testnet is the current proof point: it already exposes a full node, external miner, browser wallet, public faucet, explorer/API, and snapshot bootstrap with live reward-node registration, renewal, attestation, and settlement.
Current public claim
- Proof of Work remains the block production model.
- Verified nodes have a native on-chain reward path.
- Settlement is deterministic and consensus-visible.
- New nodes can bootstrap faster from trusted snapshots.
Monetary Model
The reward budget is integer-only and part of the capped issuance model.
Block time target
300 seconds.
Initial miner subsidy
50 CHC per block.
Node reward pool
50 CHC per epoch.
Epoch length
100 blocks.
Shared halving
Miner subsidy and node rewards follow the same halving schedule, with one halving every 111,000 blocks.
Mining Difficulty
Difficulty adjusts at a fixed window rather than on every block.
Current retarget windows
- Mainnet retarget window: 1,000 blocks.
- Testnet retarget window: 200 blocks.
- With a 300-second target block time, the testnet target window is 60,000 seconds.
- With a 300-second target block time, the mainnet target window is 300,000 seconds.
How retargeting works
Between retarget heights, the bits field stays unchanged. At the end of
each window, the next PoW target is adjusted proportionally from the real time spent
mining the previous window versus the expected time for that window.
1. Measure the real window
actual_timespan_seconds = timestamp_last_block - timestamp_first_block
2. Compare with target time
target_timespan_seconds = target_block_time_seconds * difficulty_adjustment_window
3. Retarget proportionally
next_target = previous_target * actual_timespan / target_timespan
4. Clamp the change
The real timespan is bounded between one quarter and four times the target window.
5. Respect the PoW limit
The final target can never become easier than the configured PoW limit derived from genesis_bits.
Node Rewards
Reward nodes register on-chain, warm up, renew, get verified, and settle into coinbase payouts.
Acquire CHC and register a reward node on-chain.
Complete the current testnet warmup of two epochs.
Renew on time each epoch to remain eligible.
Verifier attestations aggregate into settlement and final payouts appear on-chain.
Important property
Registration persists on-chain. Eligibility does not. Nodes that miss renewals become stale, and missed epochs are not recovered retroactively.
