It's exciting and awesome, the blockchain ledger is seen by some in the financial industry as the most compelling aspect of bitcoin because it can be used beyond merely buying and selling goods or services with a new currency.
The blockchain is maintained, updated and verified by a vast global network of independently owned computers known as “miners” that collectively work to prove the ledger’s authenticity.
In theory, this decentralized system for verifying information means transactions need no longer be channeled through banks, clearinghouses and other middlemen. Advocates say this “trustless” structure means direct transfers of ownership can occur over the blockchain almost instantaneously without the risk of default or manipulation by an intermediating third party. One idea is that encrypted, digital representations of share certificates could be inserted into minute bitcoin transactions known as “Satoshis,” facilitating an immediate, verifiable transfer of stock ownership from seller to buyer.
One way or another the Blockchain will be used in the future
The question is Bitcoins role in it.
