DeFi Use Cases - Exploring the Potential
Decentralized Finance (DeFi) is an umbrella term for various protocols and financial instruments that are built on distributed ledger technology (DLT) , such as blockchain. DeFi is transforming the way financial systems operate, offering open, transparent, and permissionless alternatives to traditional finance. Built on blockchain technology, DeFi removes intermediaries, allowing users to interact with financial services directly through decentralized applications (dApps).

Testnet and Devnet Resets Upcoming
This week, the faucets on both Testnet and Devnet faucets had their supply of test XRP depleted. Team RippleX, which operates the test networks, has been periodically moving funds back to the Testnet faucet to keep it running temporarily. Additionally, both faucets have had their default funding amount reduced to 100 XRP and the maximum amount from one request reduced. Both networks will be completely reset on Saturday, 2024-04-20. Until then, you may encounter times when the faucets are empty and cannot provide test XRP.

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?
On 2019-01-11, the fixCheckThreading and fixPayChanRecipientOwnerDir amendments lost the support of several validators, causing those amendments' support to fall below the 80% threshold for approval. (EnableAmendment LostMajority transactions: fixCheckThreading , fixPayChanRecipientOwnerDir .) As a result, these amendments are no longer expected to become enabled on 2020-01-18, and their status depends on more validators to resume voting in favor of the amendments.

XRP Testnet Has Been Reset
On 2019-08-27 at approximately 1:00 UTC (6 PM PDT), Ripple reset their XRP Testnet. This means that all accounts, balances, and settings in the Testnet have been deleted and all contents of the Testnet's decentralized exchange have been erased. However, in the process of resetting the XRP Testnet, a procedural issue caused amendments that were previously enabled to be disabled in the fresh ledger chain. Ripple plans to reset the XRP Testnet again today (2019-08-30) at 4 PM PDT. Starting at this time, the Testnet may be unavailable for a maintenance window lasting up to 4 hours.

Labeling the Internet of Value
Blockchain technology raises new questions about the roles of privacy and anonymity in the function of money. While all transactions are a matter of public record, the parties involved in the transactions are represented by pseudonyms, and information about who those parties are may be hard to come by. Even more obscure is information about those whose computing power and maintenance efforts underpin the blockchain. While there are lots of good reasons to maintain privacy around some entities and events, there are also situations that call for publicly establishing one's identity and reputation. The xrp-ledger.toml specification provides a flexible standard for voluntarily publishing information about who you are and what you're doing with the XRP Ledger.

Protecting the Ledger: Secure Development Practices
The primary mission of the C++ team at Ripple is to contribute to rippled , the reference implementation of the protocol that underpins the XRP Ledger. The codebase—which is now over 6 years old—has contributions from over 100 developers from all over the world.
The Data API, an open API that provides data to XRP Charts and third-party tools, suffered gaps in data ingestion on 2019-03-23. As a result, several metrics on XRP Charts, including the number of ledgers closed per day, were overcounted. During this time, the XRP Ledger did not experience any outages. However, the Data API's ingestion service was unable to process ledgers with transactions containing the tecKILLED transaction response code. tecKILLED is a new response code added to the XRP Ledger by amendment fix1578 on 2019-03-23. This necessitated changes to the ripple-binary-codec library used by the ingestion service, but those changes were only partially deployed to the ingestion service. We have since reprocessed and corrected the metrics that were affected by this problem.
The MultiSignReserve amendment to the XRP Ledger, introduced in rippled v1.2.0 , has gained support from a majority of trusted validators . Currently, it is expected to become enabled on 2019-04-17.

Interledger Check-in
Here at Ripple, we've been eagerly following and contributing to the progress of Interledger , a neutral standard for connecting all money systems into an Internet-like network of networks. Since finalizing the core protocol suite in late 2017, contributors from a variety of companies and backgrounds have been working hard on growing the ecosystem with implementations and infrastructure. Progress has been rapid and wild, so we thought we'd help make sense of it by checking in to see where Interledger stands today.

Statement on the “Biased Nonce Sense” Paper
In the cryptography industry, it is well known that using repeated or insufficiently random "nonces" (also called "k" values) in ECDSA digital signatures carries security risks. A new research paper authored by Joachim Breitner and Nadia Heninger discloses a more serious attack than was previously known on signatures with imperfect nonces.

The Most (Demonstrably) Scalable Blockchain
Blockchain technology is set to fundamentally transform the way the world moves value, but to do so, it must first meet a number of challenges.
Sep 21, 2017
rippled version 0.70.2
The rippled team has released , which corrects an emergent behavior that resulted in high transaction costs and fewer transactions in validated ledgers over the past few days. The problematic behavior involved large numbers of transactions being stuck in different rippled instances' open ledgers without being consistently relayed to validators. The large number of "stuck" transactions filled the transaction queue and caused a dramatic increase in the open ledger cost.

Correction to Ripple White Paper
We've recently been made aware of a paper discussing the possibility of forks in the Ripple system. We agree with the authors' conclusion that a fork is not possible given that the UNL overlap is greater than 40%. Unfortunately, this is different than the 20% figure stated in our 2014 white paper . We apologize for the oversight and are issuing a corrected version.

Validator Registry
At Ripple Labs, our goal is to expand the size and diversity of the Ripple consensus network by enabling people to easily run rippled validators and understand how those validators perform. We aim to create a network where validating participants are well known and respected by gathering and publicizing identity information of validators in addition to performance statistics.

Introducing the Data API
Ripple Labs data is moving under one roof, the Data API – a version two of the Historical Database API – and one infrastructure, Hadoop. We are building a much more robust and reliable way to import, parse, and house data that is not taxing on the Ripple network. Housing all of our endpoints together will allow us to scale much faster and with more confidence as the ledger and our data needs grow.

Turn your exchange into a Ripple Gateway
Throughout 2014 we've talked to businesses all over the world, both big and small, who are interested in tapping into Ripple's increasing liquidity and settlement capabilities. For exchanges dealing in bitcoins and other assets, the value proposition is clear - deeper orderbooks and the ability for customers to hop between different assets instantly is a major boon to their service. The natural follow-up question is how to get started.
The Stellar Development Foundation (SDF) which maintains Stellar, a network built on a modified version of the Ripple code base, recently published a post claiming flaws in the Ripple consensus algorithm. We take any reports about possible security issues very seriously and after reviewing the information conclude that there is no threat to the continued operation of the Ripple network. We'd like to share our thoughts.
