Payment and Securities Networks: Central Ledger Model in batches, relies on trusted third party & requires reconciliation

Distributed Ledger Model in real time no reconciliation Removes need for trusted third party/intermediaries but now everyone maintains the same ledger & entries done when there is consensus

Key components of a blockchain Originally conceived as the underlying protocol of Bitcoin, blockchain technology has since evolved to support a number of applications with the introduction of “smart contracts” Immutable ledger Blockchain is a write-once distributed database so it registers an immutable record of every transaction that occurs. Cryptographically secure Uses tried and true public/private signature technology. Blockchain applies this technology to create transactions that are impervious to fraud and establishes a shared truth. Decentralized consensus There are many replicas of the blockchain database and no one participant can tamper it. Consensus among the majority of participants is needed to update the database. Smart contracts The Ethereum blockchain can store and execute both data and Smart Contracts (“logic”) in the blockchain. Digital assets Blockchains have underlying cryptographic currencies, and can tokenize any asset and track it digitally and securely
