Transparency: The entire history of transactions by public addresses are made visible. Anyone using the blockchain can view a number of on-chain metrics.
Security: Once a block of data is added to the blockchain, it is impossible to alter that data. Miners ensure the security by continuously verifying transactions and reaching consensus.
Improved Traceability: Not only can we see where money is going on-chain, but also in the real world supply chain. We can also trace ownership of digital or physical goods using NFTās.
Increased efficiency & speed: There is no discrimination in the size of a transaction . A $100,000,000 transfer is processed the same as a $5 transfer. Some blockchains are faster than others, and some have added features like smart contracts, which automate contract enforcement.
Reduced Cost: There is no need to rely on third-party services. Companies can transact confidently with each-other trusting the immutable data, instead of an intermediary.
