Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. An asset can be tangible (a house, a car, cash, land) or intangible (intellectual property, patents, copyrights, branding). Virtually anything of value can be tracked and traded on a blockchain network, reducing risk and cutting costs for all involved.
Blockchain is a distributed database existing on multiple computers at the same time. It is constantly growing as new sets of recordings, or ‘blocks’, are added to it. Each block contains a timestamp and a link to the previous block, so they actually form a chain.
Blockchain technology doesn’t have to exist publicly. It can also exist privately – where nodes are simply points in a private network and the Blockchain acts similarly to a distributed ledger. Financial institutions specifically are under tremendous pressure to demonstrate regulatory compliance and many are now moving ahead with Blockchain implementations. Secure solutions like Blockchain can be a crucial building block to reduce compliance costs.
