What Is Proof-of-Immutability (PoIM)?
Proof-of-Immutability (PoIM) is a blockchain system that utilizes a sophisticated hash-based approach to store blockchain metadata in a remote hash vault.
A PoIM-powered blockchain network upholds the highest data privacy standards, as the data appended to the ledger is not copied and distributed among network nodes; instead, a hash pointer with no traceable metadata is.
This approach also empowers a blockchain to scale and attain high throughput without compromising its decentralized nature.
Enhancing Trust and Privacy
The PoIM system allows participants of the blockchain network to inspect the trustworthiness of one another’s data (by proving its immutability) at any time without invading the inspected party’s data privacy.
This mechanism for proving immutability may initially sound redundant, as immutability is perceived to be inherent to all blockchains.
Indeed, blockchain as a distributed ledger technology enjoys a higher immutability level than centralized database systems.
However, the degree of immutability varies among blockchains, depending on factors such as the consensus mechanism and the membership size.
