Blockchain : A blockchain is an immutable digital ledger that records every single transaction ever made.
- Blockchain transactions are irreversible in that, once they are recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks.
- Layer 1 and layer 2: Refer to two distinct methods of designing blockchains. While some blockchains can operate independently, others are built on top of existing blockchains to add functionality. See Link

Blockchain helps to solve double-spending problem without the need of a trusted authority or central server.

Bitcoin : Asset of value that can be interchanged securely without 3rd party. It was designed as a digital alternative to traditional currencies, aiming to provide a decentralized method of transferring value. Bitcoin transactions are verified by a network of nodes through cryptography and recorded on a public ledger called a blockchain. It has digital scarcity (concept of miners).
- Proof of Work (for consensus among miners). Comptational effort discourgaes cheating
Ethereum : While it is a cryptocurrency, is designed to be a platform that allows peer-to-peer contracts and applications to be built and run without any control, permission, or interference from third parties.
- Proof of Stake. Validator with more coins is more likely to be selected for the next one.
