Deltacoin: open-source currency, built to move.

Executive summary

Deltacoin is an open-source peer-to-peer digital currency combining Scrypt Proof of Work, Proof of Stake, full-node wallet software, and public network tools. Its current protocol preserves the original chain while defining explicit hybrid activation and difficulty boundaries. This paper describes implemented behavior separately from future project work.

Network and consensus

From block 85,000, PoW and PoS difficulty are calculated independently so the two block-production paths can respond to their own participation levels. Operational services commonly use six confirmations for ordinary transfer confidence, while generated rewards follow the 20-block maturity rule.

Issuance and monetary boundary

Before hybrid activation, the original 9,999 DECO subsidy follows the inherited 16,700-block halving schedule. Once hybrid rules are active, valid PoW blocks use the implemented 9,999 DECO subsidy and PoS blocks use 333 DECO. The code defines an 8,000,000,000 DECO maximum-money boundary for transaction-value validation.

Live indexed supply is dynamic and should be read from the official explorer. A protocol maximum is not a guarantee about market liquidity, circulation, distribution, or value.

Staking and wallet output policy

Eligible DECO outputs must be at least 24 hours old before participating in Proof of Stake. Deltacoin Core v1.1.10 presents net staking rewards, separates temporarily locked staking value from mined and pending funds, and can split large coinstake returns into more practical outputs.

The default stakesplitthreshold is 20,000 DECO. Setting it to 0 disables automatic splitting. This is local wallet policy: it affects output organization, not consensus validity, reward size, or another wallet's behavior.

Security model

Full nodes independently validate blocks, transactions, proof of work, stake eligibility, maturity, and monetary ranges. Hybrid participation does not remove normal custody risk. Users should verify release checksums, encrypt wallets, retain offline backups, and keep RPC private.

• Use official tagged releases and published SHA-256 checksums.
• Back up wallet.dat before upgrades and after key changes.
• Never expose RPC port 33603 to the public internet.
• Never disclose private keys, wallet files, passwords, or seed material.

Participation and infrastructure

Participants can run nodes, mine Scrypt PoW, stake eligible DECO, test wallets, report reproducible issues, and operate public infrastructure. The official explorer publishes blocks, transactions, confirmations, network status, peer observations, and read-only API data. The scanner provides another public view of network activity.

Public pool availability can change without notice. The mining guide links to current discovery data and explains how to verify a pool against the official chain while keeping private-node RPC boundaries safe.

Current project direction

• Implemented: maintained Windows and Linux wallets, hybrid consensus, current staking presentation and split policy, public explorer and scanner, tagged source releases.
• Operational focus: keep wallets, nodes, explorers, scanners, release metadata, and public documentation aligned with current consensus.
• Ecosystem direction: support responsible pool, exchange, bot, wallet, and community integrations where providers and maintenance paths are verifiable.
• Compatibility direction: evaluate UI and dependency modernization separately from consensus changes, with cross-platform wallet testing before release.

These are non-binding directions rather than promises. Changes remain subject to technical review, testing, security, maintainability, and available project resources.
