Fungible Token Framework

The fungible token framework uses the extended Token Taxonomy Framework standard that is supported by Blockchain App Builder.

Fungible tokens are digital assets that are interchangeable and uniform in value. Blockchain App Builder extends ERC-20 specification, which is based on the Token Taxonomy Framework (TTF), to support all phases of the fungible token life cycle including creation, development, management, and maintenance.

Example use cases:
Digital Currencies
Issuing digital representations of fiat currencies such as central bank digital currency (CBDC), stablecoins, or deposit tokens for efficient transactions in a blockchain network.
Loyalty Programs
Creating reward points that can be earned and redeemed by customers, enhancing customer engagement.
Micro-Payments
Enabling small-value transactions for blockchain transactions, marketplace services, Internet of Things (IoT) systems, or content monetization platforms.

The enhanced version of Blockchain App Builder that is included with Oracle Blockchain Platform Digital Assets Edition supports the following functions.

  • Fractional units: Divide tokens into smaller units, allowing for precise value representation.
  • Multiple fungible tokens: Create multiple fungible token types in a single smart contract (for example, multiple currencies or rewards points).
  • Minting and burning: Control the token supply in circulation by creating (minting) and removing (burning) tokens.
  • Account management: Manage account statuses, including activation, suspension, and deletion, to ensure compliance and security. One user can have multiple token accounts based on the various token types.
  • Compliance controls: Enforce account-level daily limits and run auditing procedures to adhere to regulatory requirements.
  • Transfer: Move a specified amount of fungible tokens between accounts.
  • Notary accounts: Require an additional approval step during minting, burning and transfer operations, adding an extra layer of authorization to implement the maker-checker principle.
  • Exchange pools: Exchange different types of tokens or assets atomically using liquidity pools in the blockchain network.
  • Role operations: Assign and enforce roles such as minter, burner, notary, auditor, and organization auditor to provide specific privileges to any user account.

Oracle Blockchain Platform Digital Assets Edition includes a chaincode package and a wrapper API package for the fungible token scenario. The chaincode package includes a deposit token sample, which illustrates use of the framework. The wrapper API package extends the REST API to support operations specific to the deposit token scenario.
