  2. What is Blockchain A technology that permits transactions to be gathered into blocks and recorded cryptographically chains blocks in chronological order; and allows the resulting ledger to be accessed by different servers.

  3. WHAT IS A DISTRIBUTED LEDGER? • Centralized Ledger Distributed Ledger • There are multiple ledgers, but Bank holds the “golden record” • Client B must reconcile its own ledger against that of Bank, and must convince Bank of the “true state” of the Bank ledger if discrepancies arise • There is one ledger. All Nodes have some level of access to that ledger. • All Nodes agree to a protocol that determines the “true state” of the ledger at any point in time. The application of this protocol is sometimes called “achieving consensus.”

  4. What’s that got to do with blockchain? • We have some distributed system • • We need to all agree on the state of some system • • We all agree on the initial state of the system • • A blockchain contains a history of individual transactions • • Thus: We can all agree on the current state of the system • A blockchain lets mutually-distrusting entities agree on history... ...which lets them agree on the state of the system now.

  5. What problem does a blockchain solve? • A blockchain lets us agree on the state of the system, even if we don’t all trust each other! • • Ultimate goal: We all need to agree on the state of some system. • • How much BTC in each account? • • Who owns which property? • • What’s the current state of my program? • • We can all agree on that if we agree on history. • • Starting state + history  current state • • We don’t want a single trusted arbiter of the state of the world. • • We want some level of decentralization—not a single point of failure or compromise.

  6. How does it work? • • A blockchain is a sequence of hash-chained records • • Once you’ve seen record N, you can’t change anything in the past. • • Some procedure for adding blocks to blockchain • • Who gets to add blocks? How is it done? • • Validity conditions for new blocks • • Are transactions valid? Are digital signatures correct? Etc. • • Enforced by consensus-–chains with invalid blocks won’t be accepted. • • Some procedure for deciding between alternative candidate blockchains. • • When Alice and Bob have different pictures of history, there’s some way for them to eventually come to agreement about who is right.
