Expoin.io Security: Komodo’s Delayed Proof of Work (dPoW)
Expoin is built on the Komodo framework to leverage its Delayed Proof of Work (dPoW) security mechanism. This technology protects our network by anchoring the Expoin.io ledger to the Litecoin blockchain.
TLDR
Integration with dPoW provides an efficient, robust, and economically sound security model that guarantees the integrity of our blockchain.
Mechanism
dPoW is a hybrid consensus method that notarizes our blockchain’s history onto a network with a significantly higher hashrate. This process is executed by Komodo’s 64 elected Notary Nodes.
- Validation: The network validates its own blocks.
- Hashing: Notary Nodes compute a cryptographic hash of a validated block.
- Notarization: This hash is embedded into a transaction and confirmed on the Litecoin blockchain.
To compromise the Expoin ledger, an attacker would first need to successfully attack and reorganize the Litecoin blockchain—a task considered computationally infeasible.
Core Benefits
- 51% Attack Resistance: dPoW neutralizes 51% attacks by recycling the massive hashrate of the Litecoin network for our chain’s security.
- Economic Efficiency: It provides enterprise-grade security without the prohibitive cost of generating equivalent hashrate independently.
- Verifiable Immutability: Transaction history is secured and made permanent by the much larger and more established Litecoin ledger.
