Chain Core - Open Source Ledger-as-a-Service
Bug fix release: When UTXO reservation didn’t find enough funds, it erroneously counted recently spent UTXOs, turning permanent “insufficient funds” errors into transient “outputs reserved” errors.
This is a prerelease
High availability improvements
The client keeps a list of core URLs which it uses to load balance requests to a multi-process server. It will continue to make requests to a particular URL in the list until an error occurs (at which point it should update this position to the next URL in the list). A bug has been fixed which allowed separate requests to read the same position and update it separately.
The request retry logic has also been updated to cover the maximum, potential leader election period for a multi-process server.
You can now specify trusted server SSL certificates via a PEM-encoded file:
Client client = new Client.Builder()
.setURL("https://example:443")
.setTrustedCerts("path/to/certs.pem")
.build();
To log requests, pass an OutputStream to the client builder:
OutputStream os = System.out;
Client client = new Client.Builder()
.setLogger(os)
.setLogLevel(LoggingInterceptor.Level.ALL)
.build();
