Blockchain 1.0 was the first generation of blockchain technology. It was developed in 2008 and is the underlying technology of Bitcoin, the first and most well-known cryptocurrency. Blockchain 1.0 is a distributed ledger technology that allows for secure, transparent, and tamper-proof transactions.
Blockchain 2.0 is the second generation of blockchain technology. It was developed in 2015 and builds on the foundation of Blockchain 1.0. Blockchain 2.0 is more scalable, secure, and efficient than Blockchain 1.0. It also has the ability to support smart contracts, which are self-executing contracts that can be used to automate a wide range of tasks.
Blockchain 2.0 has the potential to revolutionize a wide range of industries, including finance, healthcare, supply chain management, and government. It is still a relatively new technology, but it is already being used by a number of companies and organizations around the world.
