Bitcoin Core will also use Tor automatically to connect This means that if Tor is running (and proper authorization is available),īitcoin Core automatically creates a hidden service to listen on, without Starting with Tor version 0.2.7.1 it is possible, through Tor's control socketĪPI, to create and destroy 'ephemeral' hidden services programmatically.īitcoin Core has been updated to make use of this. Community direction on this topic is particularly requested to help More accurate priority calculation for chained unconfirmed transactions will be This internal automatic prioritization handling is being considered for removalĮntirely in Bitcoin Core 0.13, and it is at this time undecided whether the Priority delta will be ignored and only the fee metric will be effective. Note, however, that if mining priority transactions is left disabled, the Transactions already in the mempool continues to work as it has previously.
