rippled Version 0.70.0

Ripple has released rippled version 0.70.0, which introduces several enhancements that improve the reliability, scalability and security of the Ripple Consensus Ledger. Ripple recommends that all rippled server operators upgrade to version 0.70.0 by Thursday, 2017-06-29, for service continuity.

Highlights of this release include:

  • The FlowCross Amendment, which streamlines offer crossing and autobrigding logic by leveraging the new “Flow” payment engine in rippled.

  • The EnforceInvariants Amendment, which safeguards the integrity of RCL by introducing code that executes after every transaction and ensures that the execution did not violate key protocol rules.

  • fix1373, which addresses an issue that would cause payments with certain path specifications to not be properly parsed.

Ripple expects the EnforceInvariants and fix1373 Amendments to be enabled on Thursday, 2017-06-29. The FlowCross Amendment will be enabled on a future date (TBA).

Operational Note

The algorithm that determines how many threads rippled uses has been changed with this release. The new logic creates more threads, allowing the server to better leverage multi-core processing units. As a result of the increase in thread count, operators may find that their rippled instances may now utilize more memory than in the past.

Action Required

If you operate a rippled server, then you should upgrade to version 0.70.0 by Thursday, 2017-06-29, for service continuity.

Impact of Not Upgrading

If you operate a rippled server but do not upgrade to version 0.70.0 by Thursday, 2017-06-29, when EnforceInvariants and fix1373 are expected to be activated via Amendment, then your server will become amendment blocked, meaning that your server:

  • Cannot determine the validity of a ledger
  • Cannot submit or process transactions
  • Does not participate in the consensus process
  • Does not vote on future amendments
  • Could rely on potentially invalid data

If the EnforceInvariants and fix1373 Amendments do not get approved, then your server will not become amendment blocked and should continue to operate.

Set version to 0.70.0

Network Update

The Ripple operations team plans to deploy version 0.70.0 to all rippled servers under its operational control, including private clusters, starting at 2:00 PM PST on Thursday, 2017-06-15. The deployment is expected to complete within 4 hours. The network should continue to operate during deployment and no outage is expected.

At that time, rippled validators under Ripple’s operational control will begin voting for the EnforceInvariants and fix1737 Amendments.

Full Release Notes


Currently, the offer crossing code in rippled is independent of the payment flow code in rippled. The introduction of the FlowCross Amendment ensures that the same logic that drives payments also drives offer crossing. This change streamlines the code base, improves test coverage and is expected to result in some marginal performance benefits in offer crossing. For more information, see FlowCross.


The introduction of the EnforceInvariants Amendment supplements existing safeguards of RCL integrity. Once the amendment activates, the servers will execute specialized code to check key system invariants after the execution of each transaction. If a transaction fails any of the checks, it will be considered as invalid. For more information, see EnforceInvariants.

fix1373 Amendment

Version 0.70.0 also introduces the fix1373 Amendment to fix a minor bug in pathfinding that causes strand creation to fail. Specifically, the issue was related to paths that contain path elements where all the path elements types are set (account, currency and issuer). The fix1373 Amendment corrects the issue that caused some strand creation to fail. For more information, see fix1373.

These features underline Ripple’s continued support to improving RCL by making it more stable, secure and efficient for settlement of global payments.

Upcoming Features

We do not have an update on the previously announced changes to the hash tree structure that rippled uses to represent a ledger, called SHAMapV2. At the time of activation, this amendment will require brief scheduled allowable unavailability while the changes to the hash tree structure are computed by the network. We will keep the community updated as we progress towards this date (TBA).

You can update to the new version on Red Hat Enterprise Linux 7 or CentOS 7 using yum. For other platforms, please compile the new version from source.
