Cardano founder applauds XRP Ledger design after revisiting XRPL consensus model

Cardano founder Charles Hoskinson has once again drawn attention to the XRP Ledger (XRPL) after revisiting its consensus design during a live X Spaces session with David Schwartz. Hoskinson has offered fresh praise for the network’s architecture and reinforced a growing narrative of mutual respect between two of crypto’s most influential ecosystems. The Cardano founder, known for his research-driven approach to blockchain design, highlighted the XRPL’s consensus model as a “well-reasoned system,” emphasizing its efficiency, low-latency settlement structure, and long-standing focus on payments infrastructure. His remarks reflect a broader reassessment of early blockchain systems as institutional adoption and tokenization accelerate across the digital asset sector. Three days before the live session, Schwartz had joined the XRP Ledger Foundation board as an honorary member. The XRP Ledger, originally launched in 2012, uses a unique Federated Byzantine Agreement (FBA) consensus mechanism that enables transactions to settle in just a few seconds. This works without relying on proof-of-work or proof-of-stake mining. Instead, it depends on a network of trusted validator lists (UNLs) to achieve agreement. This design has long been praised for its speed and debated for its trade-offs in decentralization. A big week for Schwartz and why the timing matters The XRP Ledger Foundation announced a new leadership team on May 8, naming Brett Mollin as executive director. Denis Angell was named chief technology officer, Rene Huijsen director of operations, and Hussein “Vet” Zangana director of community. The board added Schwartz three days later because he understands the original design decisions. And three days after that, Hoskinson publicly praised the foundations that Schwartz had built in his early years. What brought Hoskinson back to XRPL? Hoskinson and his team are working on a new project called the Midnight glacier drop , and they needed to include the XRPL as one of the networks. Midnight is a privacy-focused blockchain built on Cardano, while a glacier drop is a type of token distribution. Schwartz comes in as a consultant, helping Cardano engineers navigate the technical details of building with XRPL. For the first time since 2013 or 2014, Hopkinson found a reason to review XRPL’s design. He read a paper on the Ledger’s consensus approach and looked at how it handles Byzantine agreement. In his own words, Hopkinson said, “The whole UNL concept is pretty nifty, especially if you have negative UNLs to achieve liveness again. So, there were some nice things there, and it’s just a well-reasoned system for what you guys put together.” What is the UNL, and why has it been controversial? The UNL, or Unique Node List, is a list of trustworthy computers that every computer participating in the XRP Ledger can choose. Bitcoin uses Proof-of-work, in which computers race to solve complex mathematical puzzles. Whoever solves it first earns the right to add the next batch of transactions. The XRPL works differently because nodes compare notes and reach an agreement. XRPL Foundation usually recommends a UNL of verified and vetted validators worldwide. What Hopkinson praised is the negative UNL. When trusted validators must agree before confirming a transaction, you could end up waiting indefinitely if some of them disappear. The negative UNL removes unreliable validators from the process, and that’s what Hopkinson said was well-reasoned. What has Schwartz been defending all along? Justin Bons, the founder and chief investment officer of Cyber Capital, said XRPL is essentially more centralized because the people who control the UNL control the network. For years, Schwartz pushed back against such theories, saying the UNL acts as a preventive measure against denial-of-service attacks. These attacks happen when an unlimited number of random validators flood the network. Schwarts argues that the list does not give Ripple or anyone else the power to censor any transactions. According to Bons, true decentralization works like Bitcoin mining, where anyone in a system can become a validator without permission. However, Schwarts thinks that comes with risks and that the UNL provides a workable middle ground. Hopkinson is one of the biggest critics in the space, and he built Cardano on a different principle than the one behind XRPL. The fact that he commended the UNL after studying it builds on Schwartz’s defense against Bons. Don’t just read crypto news. Understand it. Subscribe to our newsletter. It's free .

Aave Labs Proposes Major Bug Bounty Overhaul, Boosting Top Reward to $5 Million

BitcoinWorld Aave Labs Proposes Major Bug Bounty Overhaul, Boosting Top Reward to $5 Million Aave Labs has put forward a comprehensive proposal to restructure the Aave DAO’s bug bounty program, introducing a multi-platform approach and significantly increasing reward payouts for critical vulnerabilities. The proposal, if approved, would see the maximum reward for a critical bug in Core Aave V3 rise from $1 million to $5 million. Restructuring the Security Framework The proposed overhaul aims to distribute security oversight across three specialized platforms. Under the plan, ImmuneFi would manage bug bounties for Core Aave V3, Core Aave V2, and the GHO stablecoin. Sherlock would oversee the upcoming Aave V4 and the App Stack, while Cantina would handle the Aptos-based Aave V3 deployment. This segmentation is designed to leverage each platform’s expertise in different areas of the Aave ecosystem, potentially improving response times and coverage quality. Significant Reward Increases The most notable change is the substantial increase in maximum payouts. For critical vulnerabilities discovered in Core Aave V3, the top reward would jump from $1 million to $5 million. Aave V4’s maximum reward would rise from $500,000 to $2.5 million. These increases reflect the growing value locked in Aave protocols and the escalating sophistication of potential attacks in the decentralized finance (DeFi) space. Lower-tier vulnerabilities would also see adjusted reward tiers, though specific figures for those categories were not detailed in the initial proposal. Why This Matters for the DeFi Ecosystem Bug bounty programs are a cornerstone of security for DeFi protocols, which often hold billions of dollars in user assets. By increasing rewards, Aave Labs aims to attract top-tier security researchers who might otherwise focus on other high-value targets. The multi-platform approach also reduces the risk of a single point of failure in the security review process. For users and investors, this proposal signals a proactive stance on risk management, which is critical for maintaining trust in the protocol. Next Steps and Community Feedback The proposal is currently in the discussion phase within the Aave DAO governance forum. Community members and AAVE token holders will have the opportunity to provide feedback before a formal vote is scheduled. If passed, the new program would take effect shortly after approval, with the three platforms beginning their respective assignments. The timeline for implementation has not been specified, but the proposal suggests a phased rollout to ensure a smooth transition. Conclusion Aave Labs’ proposal represents a significant upgrade to the protocol’s security infrastructure. By increasing rewards and diversifying oversight, the Aave DAO is positioning itself to better protect user funds against emerging threats. The outcome of the governance vote will be closely watched by the broader DeFi community as a benchmark for security investment in the sector. FAQs Q1: Why is Aave Labs proposing this bug bounty overhaul now? Aave Labs aims to strengthen security as the protocol’s total value locked grows and as DeFi attacks become more sophisticated. The overhaul is designed to attract top researchers and distribute security coverage across specialized platforms. Q2: How will the reward increase affect Aave’s security? Higher rewards are expected to incentivize more security researchers to audit Aave’s code, increasing the likelihood that critical vulnerabilities are discovered and reported before they can be exploited. Q3: What happens if the proposal is not approved by the DAO? If the proposal is rejected, the existing bug bounty program would remain in place. Aave Labs could revise the proposal based on community feedback and resubmit it for another vote.

Circle Mints 250 Million USDC: A Look at Stablecoin Supply Growth

BitcoinWorld Circle Mints 250 Million USDC: A Look at Stablecoin Supply Growth Circle, the issuer of the USD Coin (USDC) stablecoin, has minted an additional 250 million USDC tokens. The transaction, detected by blockchain tracking service Whale Alert, originated from the USDC Treasury, a dedicated smart contract responsible for minting and burning the stablecoin. This latest mint brings the total circulating supply of USDC to over 28 billion tokens. What Drives a Large-Scale Mint? A mint of this size typically signals institutional demand for dollar-denominated digital assets. USDC is widely used as a liquidity bridge on centralized exchanges, a primary trading pair in decentralized finance (DeFi) protocols, and a settlement currency for cross-border payments. When Circle mints new USDC, it means that an equivalent amount of US dollars (or equivalent assets) has been deposited into reserve accounts. The process is transparent and verifiable through Circle’s regular attestation reports. This specific mint could be driven by several factors: an institutional client onboarding, a major exchange preparing for a listing or promotional event, or a DeFi protocol needing liquidity for a new pool. Without direct commentary from Circle, the exact catalyst remains speculative, but the market impact is often immediate. Market and Liquidity Implications An increase in USDC supply generally improves market depth on trading pairs, reducing slippage for large orders. For the broader crypto market, it is often interpreted as a neutral-to-bullish signal for liquidity, though it does not directly predict price movements for Bitcoin or Ethereum. The minting event also reinforces USDC’s position as the second-largest stablecoin by market capitalization, trailing Tether (USDT). Impact on DeFi and CeFi In DeFi, fresh USDC supply can lower borrowing rates on lending platforms like Aave and Compound, as the asset becomes more abundant. On centralized exchanges, it can lead to tighter spreads on USDC-denominated pairs. For institutional users, the mint provides immediate access to a regulated, dollar-pegged asset without relying on secondary market liquidity. Conclusion The minting of 250 million USDC is a routine yet significant event that highlights ongoing demand for regulated stablecoins. While the immediate effect is improved market liquidity, the underlying driver—whether institutional accumulation or exchange preparation—deserves attention from traders and analysts monitoring on-chain flows. Circle’s transparent minting process continues to provide verifiable data for market participants. FAQs Q1: Does minting new USDC affect its peg to the dollar? No. Each USDC token is backed by an equivalent amount of US dollars or short-term US Treasury securities held in reserve. Minting does not dilute the value of existing tokens. Q2: Who can request a USDC mint? Only Circle can initiate mints from the USDC Treasury. However, institutional clients and exchanges can request mints by depositing fiat currency with Circle, which then triggers the on-chain mint. Q3: How can I verify the USDC supply? The total circulating supply is publicly verifiable on blockchain explorers like Etherscan for the Ethereum network, as well as on Circle’s official transparency page, which publishes monthly attestation reports.

Tezos Ecosystem Unveils Quantum-Resistant Private Payment Testnet

BitcoinWorld Tezos Ecosystem Unveils Quantum-Resistant Private Payment Testnet Developers within the Tezos (XTZ) ecosystem have launched a prototype for a private blockchain payment testnet designed to be resistant to quantum computing attacks, according to a report from Cointelegraph. The prototype, named TzEL, leverages zk-STARK proofs to protect transaction data and encrypted payment metadata, marking a significant step toward future-proofing blockchain privacy against emerging computational threats. What Is TzEL and How Does It Work? TzEL is a testnet prototype developed by Tezos ecosystem contributors. It utilizes zero-knowledge Scalable Transparent Arguments of Knowledge (zk-STARKs), a cryptographic proof system that allows one party to prove possession of certain information without revealing that information itself. Unlike zk-SNARKs, zk-STARKs do not require a trusted setup, making them more transparent and potentially more resistant to quantum attacks. The testnet focuses on private payments, encrypting transaction metadata such as amounts and addresses while still enabling verification on the Tezos blockchain. This approach aims to provide users with both privacy and security, particularly against the hypothetical threat of quantum computers breaking current cryptographic standards. Why Quantum Resistance Matters Now Quantum computing remains in its early stages, but the cryptographic community has been actively preparing for a future where quantum machines could break widely used encryption algorithms like RSA and ECDSA. For blockchain networks, this poses a direct risk to the security of private keys and transaction integrity. Tezos, known for its on-chain governance and ability to upgrade without hard forks, is positioning itself to address this challenge proactively. The TzEL prototype is not yet a live mainnet feature, but it demonstrates the network’s capability to integrate advanced cryptographic methods before quantum threats become practical. Implications for the Broader Crypto Ecosystem The development of quantum-resistant privacy solutions is becoming a competitive differentiator among blockchain platforms. While many projects are exploring post-quantum cryptography, Tezos’ implementation of zk-STARKs for private payments adds a layer of privacy that could appeal to enterprises and users concerned about long-term data confidentiality. If successful, TzEL could influence how other networks approach both privacy and quantum readiness. It also highlights the growing intersection of privacy-focused cryptography and post-quantum security, two areas that have historically been addressed separately. Conclusion The launch of the TzEL testnet represents a forward-looking development in blockchain security and privacy. While still a prototype, it underscores Tezos’ commitment to adaptability and cryptographic innovation. As quantum computing advances, such proactive measures may become essential for maintaining trust in decentralized systems. FAQs Q1: What is zk-STARK and how does it differ from zk-SNARK? zk-STARK stands for Zero-Knowledge Scalable Transparent Arguments of Knowledge. Unlike zk-SNARKs, zk-STARKs do not require a trusted setup, making them more transparent and generally more resistant to quantum computing attacks. They are also scalable and produce proofs that are larger but faster to verify. Q2: Is TzEL available for public use on the Tezos mainnet? No, TzEL is currently a testnet prototype. It is not yet deployed on the Tezos mainnet. The development is intended to demonstrate feasibility and gather feedback before any potential integration into the live network. Q3: Why is quantum resistance important for blockchain privacy? Quantum computers, if realized at scale, could break many of the cryptographic algorithms that secure blockchain transactions today, including those protecting private keys and transaction data. Quantum-resistant cryptography ensures that private payments remain secure even in a future where quantum attacks are possible.
