Ixian DLT is the consensus and coordination layer of the Ixian Platform. It maintains the global ledger of transactions, IXI Names, and base presences, and provides secure, scalable, and decentralized coordination for the entire Ixian ecosystem.
At its heart is a novel consensus algorithm called Proof of Collaborative Work (PoCW) - a custom consensus unique to Ixian. It combines the security of Proof of Work with the efficiency and fairness of collaborative block signing.
- 🤝 Consensus for Everything - Ixian DLT secures transactions and IXI Names.
- 🛠️ Proof of Collaborative Work (PoCW) - Nodes submit Proof of Work solutions to earn eligibility for block signing and share in block rewards.
- 🕸️ Base Presence Tracking - DLT maintains a global, signed map of all active DLT and S2 nodes, defining sectors and enabling secure client discovery across the Ixian Platform.
- 🌐 IXI Names Registry - A decentralized naming system where human-readable names ('alice.ixi') can be mapped to cryptographic addresses, IPs, or metadata, with time-bound ownership.
- ⚡ Scalable & Efficient - Lightweight validation, optimized block structures, and low resource usage make Ixian suitable for microtransactions and IoT-scale adoption.
- ♻️ Resilient by Design - Fully distributed, fault-tolerant, and free from central points of failure.
Ixian's PoCW ensures fairness, efficiency, and strong security while avoiding the issues of traditional PoW.
- A node produces a new block candidate.
- Other nodes validate the block and sign to attest its correctness.
- If a node has signed the winning block, it earns a share of the reward.
- Not every node can sign every block.
- To qualify, a node must produce a valid PoW solution for one of the last 30 blocks (~15 minutes).
- A solution is computed as 'SHA3_512(SHA3_512(block height || block hash || recipient address || active public key hash || nonce))' and must meet minimum difficulty.
- Rewards are proportional to the difficulty of the PoW solution.
- Nodes may continue hashing after finding one solution to improve their submission and increase their share.
- The minimum signatures required for block acceptance is adaptive, based on the moving average of recent signature counts. This keeps block production in sync with current participation and reduces forks.
- Once the adaptive minimum is reached, the block is accepted and new blocks can be built on top.
- Eligible nodes may continue signing until the block reaches depth 5 (five successors). At that point, the signature set is frozen.
- Rewards are distributed via a Signing Transaction in a later block, after a maturity period.
- This delayed payout ensures fairness, prevents abuse, and stabilizes consensus.
