A decentralized, irreversible archive operates on the principle of immutability. Using technologies like IPFS (InterPlanetary File System) and blockchain ledgers, data is not stored in a single location but is distributed across a global network of nodes. Once a block of data is confirmed and added to the chain, it cannot be altered or deleted without breaking the cryptographic integrity of the entire network. This shifts the power of preservation from a central authority (which can be coerced or shut down) to a consensus mechanism, making the archive mathematically irreversible rather than just policy-protected. irreversible internet archive

Until a full global IIA exists, you can implement a personal version: This shifts the power of preservation from a
