Optimistic Rollups

Optimistic Rollups are a technology designed to make blockchain networks, such as Ethereum, faster and cheaper. They work by processing many transactions off the main blockchain and then submitting a summary of these transactions back to the main chain. This helps reduce congestion and costs while keeping transactions secure and verifiable. Instead of checking every…

ZK-Rollups

ZK-Rollups are a technology used to make blockchain transactions faster and cheaper by bundling many transactions together off the main blockchain. They use a cryptographic technique called zero-knowledge proofs to prove that all the bundled transactions are valid, without revealing their details. This allows more people to use the blockchain at once, without overloading the…

MEV (Miner Extractable Value)

MEV, or Miner Extractable Value, refers to the extra profits that blockchain miners or validators can earn by choosing the order and inclusion of transactions in a block. This happens because some transactions are more valuable than others, often due to price changes or trading opportunities. By reordering, including, or excluding certain transactions, miners can…

Nakamoto Consensus

Nakamoto Consensus is the method used by Bitcoin and similar cryptocurrencies to agree on the transaction history of the network. It combines a process called proof-of-work, where computers solve complex puzzles, with rules that help the network decide which version of the blockchain is correct. This ensures that everyone on the network can trust the…

Off-Chain Voting

Off-chain voting refers to any voting process that happens outside a blockchain network. Instead of recording each vote directly on the blockchain, votes are collected and managed using external systems, such as websites, databases, or messaging platforms. The results can later be submitted to the blockchain for verification or action if needed. This method can…

On-Chain Governance

On-chain governance is a way for blockchain communities to make decisions and manage changes directly on the blockchain. It enables stakeholders, such as token holders, to propose, vote on, and implement changes using transparent, automated processes. This system helps ensure that rule changes and upgrades are agreed upon by the community and are recorded openly…

Decentralised Exchange (DEX)

A Decentralised Exchange, often called a DEX, is a platform that allows people to trade cryptocurrencies directly with each other without using a central authority or intermediary. Instead of relying on a company or organisation to manage trades, DEXs use smart contracts and blockchain technology to automate transactions. This means users have control over their…
