Overview#
Blockchain 2.0 serves to distinguish between Bitcoin as an asset and the "blockchain as a programmable distributed trust infrastructure"[1] more generally, with additions of new scalable features of on-chain utility and extensibility.Instead of viewing the blockchain as part of the decentralization of money and payments, Blockchain 2.0 expands the scope of the technology to enable the decentralization of markets more generally, and the transaction will involve other types of assets by providing registers for certificates and rights and obligations in real estate, IPR, cars, art works and so on.
As Blockchain 2.0 is code the new application is said to be running on a new set of protocols ("blockchain 2.0 protocol"). A comparison with the protocols of the Internet and its layer of stacks illustrates the relation between blockchain 1.0 and blockchain 2.0.
blockchain can be viewed as the TCP/IP transport layer whereas the latter can viewed as HTTP, SMTP and FTP. In this context Blockchain 2.0 applications would be akin to browsers, social networks and file sharing services[5].
