Transaction

©2019 Attain, LLC

The Blockchain Transaction Process

20

___________________

Someone requests

a transaction

___________________________

The requested transaction

is broadcasted to the

network of nodes

___________________________

Network of nodes validate

the transaction through a

consensus mechanism

___________________________

New block is then added

to the existing blockchain

©2019 Attain, LLC

Terminology

21

Term Description

BlockchainShared ledger, permanently recorded, historical record, cryptographed,

secure, tamper-resistant, distributed

Node Any computer that connects to the blockchain network

LedgerRecord store (i.e., database), records are immutable, think more general

information than financial records

Block Permanently recorded data on the blockchain network

Dapp Decentralized application, open source, stored on blockchain

Smart ContractEmulate the logic of contractual clauses, runs on top of a blockchain

network

©2019 Attain, LLC

Types

Public Blockchain

• Anyone can access, but slow

Private Blockchain

• Single organization usage

Hybrid

• Federated/Consortium Blockchain

— Multiple selected organizations

• Public/Permissioned Blockchain

— Public read access

22

▪ Decentralized network

▪ Every node hosts a replica

▪ Distributed consensus

▪ No central owner of consensus

©2019 Attain, LLC

What is Blockchain?

Decentralized ledger or distributed ledger

Managed by a peer-to-peer network of nodes

Reduces the need for 3rd party intermediaries or middlemen

Linked and secured using cryptography

Each block contains a cryptographic hash of the previous block,

a timestamp, and transaction data

Resistant to tampering or modification of data

• Tampering is detected and rejected as hash is messed up

Bitcoin is the first use case leveraging blockchain

Use Case

A transaction must occur, transaction must be verified, transaction

must be stored in a block, block must be given a hash.

Land Title Records:

• Many countries now accept electronic versions of land title records.

• Others still rely on original paper documents.

• This is an imperfect system of real property records.

• This is one reason why the title insurance industry takes in billions in

revenue annually.

Use Case

Leading Blockchain Platform Vendors

An open software platform based on blockchain

technology that enables developers to build and

deploy decentralized applications

Multi-project open source collaborative effort

hosted by The Linux Foundation, created to advance

cross-industry blockchain technologies

27

©2019 Attain, LLC

Ethereum

Can look up a person’s transaction history, but not details of the

transaction itself

“Decentralized”

Identity is secure, see all transactions by their public address

Hence “transparency”… much needed accountability

“Immutable” cannot be tampered
