Electronic Documents Verification

What is the blockcerts technology that provide secure verification?

Blockcerts is an open standard for creating, issuing, viewing and verifying blockchain-based documents. These digital documents are registered on a blockchain, cryptographically signed, tamper-proof, and shareable. Blockchain can be explained in simple terms as a chain of blocks where each block is dependent on the one before it. Every block contains a hash, data and the hash from the previous block. The hash is an entirely unique identifier for each block on the blockchain.

If the data in even one single block changes, then so does its hash and this makes the whole blockchain invalid. Blockchain is maintained by a very wide network of users or nodes. The only way to tamper with a single block would be to tamper with all of the blocks, all at the very same time.

This is impossible. This is what guarantees the integrity of the data. This innovative technology gives individuals the capacity to possess and share their own official records with secure verification.
