Introducing XRP Ledger version 1.7.3

Version 1.7.3 of rippled, the reference server implementation of the XRP Ledger protocol, is now available. This release addresses an out-of-bounds memory read identified by Guido Vranken, as well as an unrelated issue identified by the Ripple C++ team that could result in incorrect use of internal data structures. By community demand, this version also introduces the NegativeUNL amendment, which corresponds to the feature which was introduced in the 1.6.0 release.

ripple-lib Drops Lodash Requirement in Browsers

Version 1.10.0 of ripple-lib, the JavaScript/TypeScript library for the XRP Ledger, no longer requires a separate Lodash script to run in web browsers. This change comes alongside other continued improvements in the library, improving the experience of developing applications on the XRP Ledger.

Introducing xrpl4j

RippleX and the XRP Ledger Foundation (XRPLF) are pleased to announce the release ofxrpl4j, a pure Java library for interacting with the XRP Ledger (XRPL). xrpl4j provides convenient tooling for developers to take full advantage of all the XRP Ledger has to offer, including wallet derivation, address encoding, transaction serialization and signing and native Java objects modeling core primitives of the rippled API.

XRP Ledger Node Configurator

by Javier Romero of Ripple

The XRP Ledger is open to anyone: all you need is a computer. For many people, using one of the many available client applications, user interfaces or portals is sufficient. But if you want to go beyond exploring the ledger or sending a payment, you need to run a server to participate as a node in the peer-to-peer network that manages the Ledger.

While the docs on xrpl.org make it fairly easy for anyone to spin up an XRP Ledger node, some nuanced configuration options can complicate the setup process. To help simplify this process, we've built the XRPL Node Configurator, a tool that walks you through setting up a node based on your use case.

Introducing xrpl-py for Pythonistas

by Team RippleX

Today, RippleX and the XRP Ledger Foundation (XRPLF) are excited to announce the launch of xrpl-py, a pure Python implementation for interacting with the XRP Ledger. The xrpl-py library simplifies the hardest parts of XRP Ledger interaction—like serialization and transaction signing—by providing native Python methods and models for XRP Ledger transactions and core server API (rippled) objects.

Three Amendments Expected on 2021-04-08

Two bug-fixing amendments to the XRP Ledger protocol and one amendment that improves robustness of consensus, all introduced in rippled v1.6.0, have gained support from a majority of trusted validators: fix1781, fixAmendmentMajorityCalc, and HardenedValidations. Currently, they are expected to become enabled on 2021-04-08. Any of these amendments that continue to have the continuous support of at least 80% of trusted validators will become enabled on the scheduled date.

Server operators should be sure to upgrade rippled before this date.

Message Routing Optimizations, Pt. 1: Proposal & Validation Relaying

by Gregory Tsipenyuk and Nikolaos D. Bougalis of Ripple

Like all peer-to-peer networks, the XRP Ledger needs a strategy to ensure that messages are propagated across the network. Of course, some types of messages are more important or more time-sensitive than others, so the XRP Ledger uses different strategies for relaying different types of messages.

This blog post discusses the message propagation strategy used for “proposal” and “validation” messages, which are part of the consensus protocol, and the improvements that the RippleX team researched and is contributing.

Community Spotlight: Developing Wallet Protect

GateHub started in 2013 with an idea: What if there was a wallet that could hold any type of asset, have an integrated exchange built-in and provide the ability to send and receive assets across any payment network instantly?
