  • Encryption: The process of changing the string of letters/numbers to another string of letters/numbers through a method of private translation.
  • Wallet: Etherium wallet An interface that is used to manage the Ethereum accounts
  • Account: The account contains a public and private key pair that holds the funds to be stored in a Blockchain

  • Uncle inclusion mechanism: A mechanism in Ethereum, where a block includes its uncles, which makes sure that miners that create blocks and are not included in the main chain will still be rewarded
  • EVM code: Ethereum virtual machine (EVM) code, is a programming language in which the codes are written in an Ethereum Blockchain account
  • Message: Message is a sort of Virtual transaction sent by EVM code from one account to another.
  • Transaction: In Ethereum, the transaction is a piece of digitally signed data originating from a source other than executing EVM codes.
  • Storage: A key/value database in each account where keys and values are 32-byte strings.
  • Externally owned account: The accounts which are controlled by private keys and do not contain EVM codes
  • Contract: An account that is controlled by EVM and contains EVM codes.
  • Gas: A measurement roughly equivalent to the computational steps,.
  • Serialization: Serialization is a process of converting data structure into a sequence of bytes.
  • RLP encoding: Recursive length prefix(RLP) encoding function takes in an item, an item can be a string or a list of items or strings.
  • Solidity: Solidity is a contract-oriented programming language for writing and implementing smart contracts on the blockchain
  • ABI: A data encoding scheme called “ Application Binary Interface” (ABI) is used in Ethereum for work with smart contracts
