The blockchain is a ledger of transactions, which is decentralized, immutable and auditable. It is an abstract concept. One cannot say blockchain is slow — or insecure. If it is slow or insecure, then it has to be a blockchain implementation. Differentiating blockchain as a concept from its implementation is quite important in understanding its potential. Bitcoin is the very first implementation of blockchain, and due to the same reason, people who talk about blockchain, literally mean the bitcoin blockchain. This talk covers the key fundamentals of blockchain.
1. Distributed vs. Decentralized
3. Distributed Consensus
6. Byzantine Generals Problem
7. Double Spending Problem
8. Permissioned/Permissionless Blockchain
9. Bitcoin fundamentals
