Distributed Ledger Technology
Learning Outcome Statement:
describe financial applications of distributed ledger technology
Summary:
Distributed Ledger Technology (DLT) offers significant advancements in financial services and record-keeping through enhanced accuracy, transparency, and security. It facilitates peer-to-peer interactions and faster ownership transfers, utilizing consensus mechanisms like Proof of Work and Proof of Stake for transaction validation. DLT supports smart contracts and can handle various digital assets, including cryptocurrencies and tokens, across permissioned and permissionless networks.
Key Concepts:
Distributed Ledger
A type of database spread across multiple sites, countries, or institutions. Records are stored one after the other in a continuous ledger.
Consensus Mechanism
A system used in blockchain technologies to achieve necessary agreement on a single data value or a single state of the network among distributed processes or multi-agent systems, such as cryptocurrencies.
Proof of Work (PoW)
A consensus mechanism that requires a participant node to prove that work of some quantity has been expended towards solving a computationally expensive problem.
Proof of Stake (PoS)
A type of consensus mechanism where a person can mine or validate block transactions according to how many coins they hold, promoting mining power based on the percentage of coins held by a miner.
Permissioned and Permissionless Networks
Permissionless networks allow anyone to join and participate in the network while permissioned networks restrict the participants and what each participant can do within the network.
Smart Contracts
Self-executing contracts with the terms of the agreement directly written into lines of code, which automatically execute when conditions are met.
Digital Assets
Assets that exist in a digital format and come with the right of use. They can be cryptocurrencies, tokens, or other types of digital formats.
