Absolute trust

Enabling trust by removing the need for it.

Today's traditional identity systems require us to provide trust without proof. They ask us to have faith that the information they hold has not been compromised. Blockchain changes this, providing a way to prove the integrity of the data it contains, providing absolute trust by removing the need for it.

Providing the security of cryptography with the accessibility of the internet, blockchain offers a more secure way to access and verify key information and enable trust.

Initially developed for cryptocurrency transactions, blockchain can take on any form and can be used to record transactions of any type to provide a secure, shared, transparent network of information.

A digital ledger

Blockchain is a unique type of database, a digital record of transactions designed to be far more robust than a standard database, making it ideal for securing sensitive data.

Immutable data

Storing information in a way that's virtually impossible to add, remove or modify data without being detected, blockchain allows us to trust the integrity of its data.

A decentralized system

Unlike traditional systems, where data is held and verified by a single central authority, blockchain data is duplicated and distributed across a network of computers, and verification is provided by consensus.

How blockchain works.

A blockchain records transactions into blocks then connects them using cryptography to form a chain of interconnected data that's virtually impossible to break.

Building blocks

Transaction data is recorded on the blockchain, where it's timestamped and shared with other computers in the blockchain network.

Making a chain

When a new block is created, it's shared with the network and added to the chain. Timestamps ensure that data is added in the correct order and that everyone is using the latest version.

Linking data

Each time a new block is added to the chain, the data contained in the previous block is passed through a cryptographic formula to generate a unique string called a hash. This hash is added to data in the new block.

This process is repeated every time a block is added, connecting each block to every block that came before it. This is the key to blockchain's security as it provides a connection between blocks that is virtually impossible to break without detection.

A break in the chain

If there's an attempt to modify, add or delete data in a block, the hash written in the next block will no longer match, and this mismatch will continue through all subsequent blocks, alerting the network to any changes in the chain.

Establishing trust

All network members hold a duplicate copy of the blockchain, and when queried, compare records. If the hashes match, they know that the data has not been tampered with and can trust it fully.
