Fundamentals of Blockchain
Blockchain is a secure, shared, distributed ledger that facilitates the process of recording transactions and tracking assets in a business network.
An asset can be tangible — a house, a car, cash, land — or intangible like intellectual property, such as patents, copyrights, or branding.
Virtually anything of value can be tracked and traded on a Blockchain network, reducing risk and cutting costs for all involved.
What is Blockchain?
Three Principle Technologies Combine to Create Blockchain
Not new but their orchestration and application
Distributed P2P Network that hosts a shared ledger
Incentive to service the network’s txns, record keeping and security
Key Characteristics of Blockchain
Consensus: For a transaction to be valid, all participants must agree on its validity
Provenance: Participants know where the asset came from and how its ownership has changed over time.
Immutability: No participant can tamper with a transaction after it’s been recorded to the ledger. If a transaction is in error, a new transaction must be used to reverse the error, and both transactions are then visible.
Finality: A single, shared ledger provides one place to go to determine the ownership of an asset or the completion of a transaction.
Participants and Roles
Blockchain Network Participants and their Roles
Traditional processing platforms
Traditional Data sources
Does my business network need to manage contractual relationships?
Do we need to track transactions that involve more than two parties?
Is the current system overly complex or costly, possibly due to the need for intermediaries or a central point of control?
Can the network benefit from increased trust, transparency, and accountability in recordkeeping?
Is the current system prone to errors due to manual processes or duplication of effort?
Is the current transaction system vulnerable to fraud, cyber-attack, and human error?
What is Bitcoin?
Public Blockchain Network
Application over Blockchain
Email over Internet
o – An unregulated shadow-currency
o – The first blockchain application
o – Resource intensive
Blockchain underpins Bitcoin
o Blockchain for business differs in key areas:
o Identity over anonymity
o Selective endorsement over proof of work
o Assets over cryptocurrency
