Proof-of-Immutability (PoIM)

Proof-of-Immutability (PoIM) is a blockchain system that introduces an innovative approach to storing blockchain metadata. Unlike traditional blockchain networks, PoIM-powered networks do not distribute and copy data among network nodes. Instead, they utilize a remote hash vault and employ a hash pointer that does not contain any identifiable metadata. This unique method ensures the highest standards of data privacy while allowing the blockchain to scale and achieve high throughput without compromising its decentralized nature.

The primary purpose of PoIM is to enable participants in the blockchain network to verify the integrity of each other’s data, thereby proving its immutability. Immutability is a fundamental characteristic of all blockchains, ensuring that once a transaction or record is added to the blockchain, it cannot be altered or tampered with. However, the level of immutability can vary depending on factors such as the consensus mechanism and the size of the network. Smaller permissioned or private blockchain networks, for example, are often more susceptible to manipulation.

PoIM addresses this concern by providing a mechanism that allows participants to detect any manipulation or alteration of records without accessing the underlying database. This mechanism protects the integrity of the blockchain and enhances trust among participants. Furthermore, as the adoption of blockchain technology increases, there is a growing need for an auditing mechanism to validate the integrity of information within the blockchain ledger. This validation is crucial for the legal recognition of blockchain data and smart contracts.

It is worth noting that PoIM was developed by ParallelChain Lab and has been patented. The patents include US-2021-0297265-A1, US-2021-0218549-A1, EP3848845, and CN2021102000629400. The PoIM system was initially implemented on ParallelChain Private and is expected to be implemented in “Inter-ParallelChain Communication,” which aims to meet the trust and data privacy protection requirements of both permissioned and permissionless networks in the Web3 ecosystem.
