Here are the main features of blockchain technology:

Bitcoin transactions are recorded on a public, distributed ledger known as a “blockchain” that anyone can download and help maintain.

Transactions are sent directly from the sender to the receiver without any intermediaries.

Holders who store their own bitcoin have complete control over it. It cannot be accessed without the holder’s cryptographic key.

Bitcoin doesn’t exist in a physical form.

Bitcoin has a fixed supply of 21 million. No more bitcoin can be created and units of bitcoin cannot be destroyed.

Bitcoin users send and receive coins over the network by inputting the public-key information attached to each person’s digital wallet.
