This is Steve's outline for a Blockchain talk to Lexington Computer Group

This is a work in progress. blockchain_notes

How are Bitcoin and blockchain related? Bitcoin uses blockchain. Blockchain is used for Bitcoin, and much, much more.
This talk gives a simplistic overview of blockchain.

Concepts

  • Data store (holds transactions)
  • Replication (many people hold the chain)
  • Cryptography and digital signatures
  • Immutable (hard to change history and changes are detectable)
  1. Use of Blockchain for ledgers
  2. Hashing basics
  3. Public Key Infrastructure basics
  4. Block contents
  5. Add new block
  6. Need for Mining

Overview - How does blockchain work?

(This section has material copied directly from https://www.ibm.com/blockchain/what-is-blockchain)

  • As each transaction occurs – and the parties agree to its details – it’s encoded into a block of digital data and uniquely signed or identified.
  • Each block is connected to the one before and after it — creating an irreversible, immutable chain.
  • Blocks are chained together, preventing any block from being altered or a block being inserted between two existing blocks.

Difference between blockchain and Bitcoin

  • Bitcoin: unregulated, digital currency.
  • Blockchain: is used by Bitcoin (and blockchain used for many other things)
