Blockchain in the Fast Lane

Security, decentralization and scalability are often seen as the three key aspects of blockchain technology. Security is achieved due to the cryptographic link between transactions within the blockchain. Decentralization is accomplished by the fact that a plurality of computers, as opposed to a single computer, are utilized to operate and validate transactions within the blockchain. Scalability, however, has not yet been meaningfully achieved. Scalability is the ability of a blockchain to support an increasing number of users and transactions. In order for blockchain technology to reach mass adoption, the scalability issue must be resolved.
