The primary benefit of blockchain is as a database for recording transactions, but its benefits extend far beyond those of a traditional database. Most notably, it removes the possibility of tampering by a malicious actor, as well as providing these business benefits:

• Time savings. Blockchain slashes transaction times from days to minutes. Transaction settlement is faster because it doesn’t require verification by a central authority.
• Cost savings. Transactions need less oversight. Participants can exchange items of value directly. Blockchain eliminates duplication of effort because participants have access to a shared ledger.
• Tighter security. Blockchain’s security features protect against tampering, fraud, and cybercrime.
