A type of blockchain where everyone can participate. It's a global peer-to-peer network. Examples are cryptocurrencies, DeFi, certificates, royalties, and points.

A consensus algorithm is a form of governance to ensure trust between parties. Samples are Proof of Work (PoW), Proof of Authority (PoA) and Proof of Stake (PoS).

A type of blockchain where the ownership and responsibility lies within a single company. Examples are asset management, governance of subsidiaries, and company-wide compliance.

A type of blockchain where different companies partner together. Examples are supply chain, licensing & accreditations, and tourisms.

DApps (Decentralized Applications) are apps that utilised data from the blockchain. They use web3 libraries to interface with on-chain data.

Solidity is a popular contract-oriented programming language that is used t o write smart contracts.

It's a global and open-source platform for DApps (dentralized applications). Developers can write smart contracts and deploy it to the Ethereum network.

Sometimes abbreviated as "ETH". It's the native currency of Ethereum blockchain. This is what you use to pay for "gas fees" in order to interface with smart contracts.

It's a fee for a transaction to be "mined" or final. Gas is a unit of measurement of how complex a smart contract execution is.

In Ethereum blockchain, there are various test networks like Ropsten. The "Main Net" is the public and verified main network that real-world smart contracts are deployed.

It means nobody can change any information once it's committed on the blockchain.

Smart contracts deployed on the blockchain can't be altered.

For as long as there are active blockchain nodes, Dapps will always be available.

Stablecoins are blockchain-issued tokens that have been designed to be stable by pegging their value to an outside asset (usually the USD or gold).

MakerDAO is a decentralized credit platform on Ethereum that supports Dai, a stablecoin whose value is pegged to USD.

DeFi is similar to how we call Financial Technologies as "FinTech". It's an industry vertical use of decentralised technologies that are specific to Financial products. This includes exchanges, lending & borrowing, interests & compounds, staking & liquidity pools, and many more.

A shared universe where you can live, work, and play. It is an immersive experience that goes beyond virtual reality and social networking.

Liquidity pools are token reserves that sit on smart contracts and are available for users to exchange tokens with.

Decentralized exchanges make use of some innovative asset swapping methods such as atomic swap to exchange tokens and assets with minimal risk and within a very short time.

It's a popular digital peer-to-peer cryptocurrency without needing a central bank or authority. It uses distributed ledger and blockchain technologies.
