The DatabaseImp has threads that asynchronously call JobQueue to perform database reads. Formerly these threads had the same lifespan as Database, which was until the end-of-life of ApplicationImp. During shutdown these threads could call JobQueue after JobQueue had already stopped. Or, even worse, occasionally call JobQueue after JobQueue's destructor had run. To avoid these shutdown conditions, Database is made a Stoppable, with JobQueue as its parent. When Database stops, it shuts down its asynchronous read threads. This prevents Database from accessing JobQueue after JobQueue has stopped, but allows Database to perform stores for the remainder of shutdown. During development it was noted that the Database::close() method was never called. So that method is removed from Database and all derived classes. Stoppable is also adjusted so it can be constructed using either a char const* or a std::string. For those files touched for other reasons, unneeded #includes are removed.
What is Ripple?
Ripple is a network of computers which use the [Ripple consensus algorithm] (https://www.youtube.com/watch?v=pj1QVb1vlC0) to atomically settle and record transactions on a secure distributed database, the Ripple Consensus Ledger (RCL). Because of its distributed nature, the RCL offers transaction immutability without a central operator. The RCL contains a built-in currency exchange and its path-finding algorithm finds competitive exchange rates across order books and currency pairs.
Key Features
- Distributed
- Direct account-to-account settlement with no central operator
- Decentralized global market for competitive FX
- Secure
- Transactions are cryptographically signed using ECDSA or Ed25519
- Multi-signing capabilities
- Scalable
- Capacity to process the world’s cross-border payments volume
- Easy access to liquidity through a competitive FX marketplace
Cross-border payments
Ripple enables banks to settle cross-border payments in real-time, with end-to-end transparency, and at lower costs. Banks can provide liquidity for FX themselves or source it from third parties.
As Ripple adoption grows, so do the number of currencies and counterparties. Liquidity providers need to maintain accounts with each counterparty for each currency – a capital- and time-intensive endeavor that spreads liquidity thin. Further, some transactions, such as exotic currency trades, will require multiple trading parties, who each layer costs to the transaction. Thin liquidity and many intermediary trading parties make competitive pricing challenging.
XRP as a Bridge Currency
Ripple can bridge even exotic currency pairs directly through XRP. Similar to USD in today’s currency market, XRP allows liquidity providers to focus on offering competitive FX rates on fewer pairs and adding depth to order books. Unlike USD, trading through XRP does not require bank accounts, service fees, counterparty risk, or additional operational costs. By using XRP, liquidity providers can specialize in certain currency corridors, reduce operational costs, and ultimately, offer more competitive FX pricing.
