Introducing XRP Ledger (rippled) version 1.2.0

Ripple is pleased to announce the release of XRP Ledger ( rippled ) version 1.2.0.

The XRP Ledger version 1.2.0 release introduces the MultisignReserve Amendment, which reduces the reserve requirement associated with signer lists for Multisign. This release also includes incremental improvements to the code that handles offers in the decentralized exchange (fixTakerDryOfferRemoval and fix1578 Amendments).

One of the major benefits of decentralized blockchain technologies, such as the XRP Ledger, is censorship resistance. Already highly resistant to censorship attempts, with the release of version 1.2.0 of the XRP Ledger, servers now have the ability to automatically detect transaction censorship attempts and issue warnings of increasing severity for transactions that a server believes should have been included in a closed ledger after several rounds of consensus.

Action Required

If you operate an XRP Ledger server, then you should upgrade to version 1.2.0 by Wednesday, 2019-02-27, to ensure service continuity.

Impact of Not Upgrading

Ripple expects the MultisignReserve, fixTakerDryOfferRemoval, and fix1578 amendments to become enabled no earlier than Wednesday, 2019-02-27. When this happens, if you are not running release 1.2.0 or greater, your server will become amendment blocked, meaning that it:

Cannot determine the validity of a ledger;

Cannot submit or process transactions;

Cannot participate in the consensus process;

Cannot vote on future amendments; and

Could rely on potentially invalid data.

If the MultisignReserve, fixTakerDryOfferRemoval, and fix1578 amendments do not become enabled, then your XRP Ledger server will not become amendment blocked and should continue to operate.

Upgrading

On supported platforms, see the instructions on updating rippled .

The SHA-256 for the RPM is: a6982002a5e7c3abb0078e9c986e4c28c8310ca67defa5f74a1b3581cc9bc0a4

The SHA-256 for the source RPM is: 1927e5411619cc66170730342f1a7c38f6eafae8c4246d68e24cc0ad4fd62b9e

For other platforms, please compile version 1.2.0 from source.

The first log entry should be the change setting the version:

commit 7779dcdda00ea61a976cf5f387bc1f3bb4ebbfdd Author: Mike Ellery <mellery451@gmail.com> Date: Tue Feb 12 16:41:03 2019 -0800 Set version to 1.2.0

The Ripple technical operations team plans to deploy version 1.2.0 to all XRP Ledger servers under its operational control, including private clusters, starting at 2:00 PM PST on Wednesday, 2019-02-13. At that time, Ripple plans to start voting in favor of the fix1578 amendment. The deployment is expected to complete within 4 hours. The network should continue to operate during deployment and no outage is expected.
