Balances
This is used to represent any type of store of value in your Ledger, e.g., bank accounts, wallets, card balances, store points, escrow wallets, liquidity partners, etc. All transactions must flow between these balance accounts as source or destination.Blnk Ledger
This is a tool that allows you to keep an accurate system of record for your app’s financial data. It is free to use as a part of our open-source Core.Cloud
The Blnk Cloud is the platform for viewing and acting on your financial data without code. It brings teams, financial data, and advanced concepts together in one place. Each Cloud account is tied to one organisation and is referred to as a Cloud workspace. You can add as many users or instances as you want to a Cloud workspace.Core
Short form of open-source Core, also known as, Blnk Core.Double-Entry
Double-entry is an accounting principle that states that every transaction must have a debit entry and a corresponding credit entry. Blnk implements this as a transaction having both a source (where it came from) and a destination (where it went to).Identities
Use identities to create and manage your customers’ profiles in your core system. Identities can also be linked to one or more balances to get better insights into who is involved in a transaction.Inflight
A transaction with inflight is held in transit until a defined set of conditions have been met. If met, the transaction is committed and processed successfully. If not, the transaction is voided.Instances
An instance refers to a single deployment of the Blnk Core on a server. This can be on a local development environment, staging or production environment. To use Cloud, you are required to connect a live instance to your workspace. You can deploy and connect as many instances as you want for your application.Ledgers
A ledger groups similar balances in your Blnk Ledger together. You can group balances by use case, product type, customer, currency, etc, e.g., USD Wallets Ledger, Debit Cards Ledger, etc.Metadata
Blnk is designed with default attributes for each record. Add custom metadata to extend your Ledger records with additional information, e.g., you can include, track, and update the KYC verification status of an identity in its metadata.Money Movement Map
This is a foundational concept for integrating the Blnk Ledger. Maps visualise the flow of funds in your system. This makes it easy for developers to programmatically convert money movement requirements into code.Negative Balance
A negative balance amount means the balance has more debits than credits. Balances are calculated ascredit_balance - debit_balance; if the debit balance is higher, the result will be mathematically negative.
