Introducing XRP Ledger (rippled) version 1.1.2

2018-12-12 03:08

XRP Ledger (rippled) version 1.1.2 is now available.

The XRP Ledger version 1.1.2 release includes a fix for a technical issue in the consensus “preferred ledger by branch” code, which could cause a validator to fail to settle on a single preferred branch of unconfirmed ledger history. While this is not entirely unexpected and the code is designed to handle it, this issue exposed a corner case where the stringent safety guarantees of the consensus algorithm, as outlined in the recent Analysis of the XRP Ledger Consensus Protocol paper, make it difficult for the entire network to efficiently recover from this condition.

Action Required

If you operate a XRP Ledger validator server, then you should upgrade to XRP Ledger version 1.1.2 as soon as possible.

Impact of Not Upgrading

If you are not running release 1.1.2 or greater, then your validator server can potentially fail to settle on a single preferred ledger branch during consensus and resort to issuing partial validations, until it can resync with the network.

The Genesis Files: With Bit Gold, Szabo Was Inches Away From Inventing Bitcoin

As his Hungarian parents had fled post-war Soviet regime to settle in the United States, Nick Szabo came to call the Californian Bay area of the 1990s his home. Here, he was among the first to frequent the in-person “Cypherpunk” meetings organized by Timothy May, Eric Hughes and other founding members of the collective of cryptographers, programmers and privacy activists centered around the ’90s mailing list of the same name.
