Open-Transactions

The Open-Transactions project is a collaborative effort to develop a robust, commercial-grade, fully-featured, free-software toolkit implementing the OTX protocol as well as a full-strength financial cryptography library, API, CLI, and prototype server. The project is managed by a worldwide community of volunteers that use the Internet to communicate, plan, and develop the Open-Transactions toolkit and its related documentation.

Open-Transactions democratizes financial and monetary actions. You can use it for issuing currencies/stock, paying dividends, creating asset accounts, sending/receiving digital cash, writing/depositing cheques, cashier's cheques, creating basket currencies, trading on markets, scripting custom agreements, recurring payments, escrow, etc.

Open-Transactions uses strong crypto. The balances are unchangeable (even by a malicious server.) The receipts are destructible and redundant. The transactions are unforgeable. The cash is untraceable. The cheques are non-repudiable. Etc.

This product includes software developed by Ben Laurie for use in the Lucre project.

Documentation

• Start here: Using the API

• High-level API (C++)

• High-level API (all other languages)

• Low-level API (C++)

• Low-level API (all other languages)

The general rule of thumb is: Always prefer the high-level API. Only use the low-level calls in cases where no high-level version is available.
