| + | See updated Glossary: [https://internetcomputer.org/docs/current/references/glossary/ ICP Glossary] |
| − | The '''replica''' is a collection of protocol components that are necessary for a node to participate in a subnet.

| − | ===== account =====
| |
| − | A ledger '''account''' is a set of entries in the [[#ledger canister| ledger canister]], which is a smart contract that mimics the guise and behavior of a regular banking account, whose unit of measure is [[#ICP| ICP]] (Internet Computer Protocol) utility tokens. Ledger accounts are owned by [[#principals| principals]], and their ownerships do not change over time. Every account on the ledger has a positive [[#balance| balance]] measured in ICP with a precision of eight decimals.
| |
| − | | |
| − | ===== address =====
| |
| − | In the context of transactions on the ledger, '''address''' is synonymous with [[#account| account]].
| |
| − | | |
| − | ===== balance =====
| |
| − | The '''balance''' of an [[#account| account]] on the ledger is the sum of all deposits minus the sum of all withdrawals. As a degenerate case, it is sometimes useful to say that an account which is not present in the ledger has a balance of zero.
| |
| − | | |
| − | The balance of a ledger account is denominated in ICP and is represented with eight decimals. Thus, the minimum positive balance of an account is 0.00000001 or 10^-8 [[#ICP| ICP]]; this amount is sometimes referred to as one '''e8'''.

| − | ===== batch =====
| |
| − | A '''batch''' is a collection of [[#messages| messages]] whose order is agreed upon by [[#consensus| consensus]].
| |
| − | | |
| − | ===== beneficiary =====
| |
| − | The '''beneficiary''' of an [[#account| account]] is the [[#principal| principal]] who owns the [[#balance| balance]] of the account. The beneficiary of an account cannot be changed. The beneficiary of an account may or may not be allowed to make transactions on the account (see [[#fiduciary| fiduciary]]).
| |
| − | | |
| − | ===== blockchain =====
| |
| − | A '''blockchain''' is a growing list of cryptographically linked blocks, agreed upon by [[#consensus| consensus]]. On the [[#Internet computer| Internet Computer]] every [[#subnet| subnet]] is a blockchain and these blockchains interact using [[#chain key cryptography| chain key cryptography]].

| − | ===== burning transaction =====
| |
| − | A '''burning transaction''' is the process of "burning" [[#ICP| ICP]], whereby a certain amount of ICP are destroyed. The main use case is that of purchasing [[#cycles| cycles]], through which ICP are destroyed while at the same time a corresponding amount of cycles is created, using the current exchange rate between ICP and ([[#SDR| SDR]]), in such a way that one SDR corresponds to one trillion (10E12) cycles. It is represented as a [[#transaction| transaction]] from the source [[#account| account]] to the [[#ICP supply account| ICP supply account]].
