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 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…

Chain reorganisation is a process that occurs in blockchain networks when two versions of the transaction history temporarily exist and the network must decide which one to continue building upon. This usually happens when miners find blocks at nearly the same time, creating competing chains. The network resolves this by choosing the longest valid chain,…

A consensus mechanism is a method used by computer networks to agree on a single source of truth, even when many participants are involved. It ensures that all records or transactions are accurate and trustworthy, preventing fraud or errors. This process is vital for systems like blockchains, where no central authority exists to oversee decisions.
