Oracle

Oracles are essential infrastructure components that feed real-time, off-chain data (such as price feeds, weather, or sports results) into blockchain smart contracts. Without decentralized oracles like Chainlink and Pyth, DeFi could not function. In 2026, oracles have evolved to support verifiable randomness and cross-chain data synchronization. This tag covers the technical evolution of data availability, tamper-proof price feeds, and the critical role oracles play in ensuring the deterministic execution of complex decentralized applications.

From Wisdom of Crowds to Manipulation Risks

From Wisdom of Crowds to Manipulation Risks

The post From Wisdom of Crowds to Manipulation Risks appeared on BitcoinEthereumNews.com. Prediction markets are rising strongly, from the hundreds of millions of dollars raised by Kalshi and Polymarket to their growing applications across crypto and traditional finance.  Considered a new asset class, prediction markets promise to change how people consume information — instead of reading headlines, they will look at odds to assess probabilities. Behind this enormous potential, however, lie the risks of regulation, manipulation, and herd behavior, forcing investors to remain cautious in the face of this “data wave.” When Prediction Markets Become “An Asset Class” Prediction markets are emerging as forecasting tools and a new asset class within the crypto ecosystem. Platforms and venture funds are beginning to bet on commoditizing information and probabilities. Sponsored Sponsored This has triggered a “prediction market war,” with massive fundraising rounds, backing from top venture capital firms, and expansion into new use cases — all fueling competition. It shows how the market is shifting from “news” to “odds” as a source of value. Comparison between Polymarket & Kalshi platforms. Source: Delphi Digital Investors increasingly view prediction markets as a strategic asset class, not just entertainment or research products. While this competition accelerates innovation, it also introduces systemic risks if the business models are not yet sustainable. Many community members call this the “next big wave” of the current cycle. They argue that the next generation of users won’t read headlines anymore but will “check the odds.” In theory, prediction markets work well because they aggregate scattered information from many participants and turn it into a number representing collective wisdom — sometimes even more accurate than expert forecasts. This explains why protocols and projects focused on prediction highlight the “wisdom of crowds” advantage in pricing event probabilities. On the other hand, this advantage only materializes when the market has enough liquidity, transparency, and protection…

Clippers And Leonard Mess Is A Pandora’s Box For Pro Sports

Clippers And Leonard Mess Is A Pandora’s Box For Pro Sports

The post Clippers And Leonard Mess Is A Pandora’s Box For Pro Sports appeared on BitcoinEthereumNews.com. LOS ANGELES, CALIFORNIA – JULY 24: (L-R) President of Basketball Operations Lawrence Frank, head coach Doc Rivers, Paul George, Kawhi Leonard and owner Steve Ballmer of the Los Angeles Clippers attend the Paul George and Kawhi Leonard introductory press conference at Green Meadows Recreation Center on July 24, 2019 in Los Angeles, California. (Photo by Kevork Djansezian/Getty Images) Getty Images Pablo Torre reported Los Angeles Clippers owner Steve Ballmer facilitated $28 million in ghost endorsements to two-time National Basketball Association Finals MVP Kawhi Leonard, a seismic story for the NBA and professional sports at-large. Listening to his work, and having built and investigated financial compliance in sport for years, my immediate reaction was that this is opening pandora’s box. I encourage people to watch the video, but for those preferring to the written word, a breakdown of what exactly happened, why it matters and where gaps in the investigation still exist follows. Leonard, the Clippers and the NBA have not responded, and should be afforded the opportunity to do their own investigation. INGLEWOOD, CALIFORNIA – APRIL 24: Kawhi Leonard #2 of the Los Angeles Clippers reacts after defeating the Denver Nuggets in Game Three of the Western Conference First Round NBA Playoffs at Intuit Dome on April 24, 2025 in Inglewood, California. (Photo by Ronald Martinez/Getty Images) Getty Images How The NBA Compensation Restrictions Work Player salaries in the NBA are not a free market; there is a Collective Bargaining Agreement with the National Basketball Player’s Association that governs compensation, colloquially called the salary cap. In essence, the money that players make for playing basketball is tabulated – by team – and restricted by a series of complex rules. Think of it like a spreadsheet, with players in one column, and dollars in another. Money from external sources, such as…

Unified security layers may accelerate institutional crypto adoption

Unified security layers may accelerate institutional crypto adoption

The post Unified security layers may accelerate institutional crypto adoption appeared on BitcoinEthereumNews.com. Shared security protocols are positioning themselves as solutions to infrastructure challenges that have complicated institutional blockchain adoption due to unified security layers’ potential ability to reduce development costs and technical barriers for enterprises. According to Symbiotic CEO Misha Putiatin, the shared security model allows organizations to leverage existing blockchain security infrastructure rather than building custom systems. Shared security consists of a unified layer where users stake assets, and multiple applications can build upon that security-focused infrastructure. This structure enables institutions to address development timelines and allocate resources effectively. In an interview with CryptoSlate, Putiatin described the value proposition as immediate scalability through reusable security primitives. Organizations can utilize existing operator sets and benefit from established infrastructure rather than developing systems independently over multiple years. Multi-chain infrastructure challenges Traditional cross-chain verification has presented enterprises with limited options, each carrying distinct trade-offs. Trusted messenger systems require allowlisting specific authorities and relying on off-chain agreements, while light client implementations demand extensive development resources and ongoing maintenance. Shared security protocols aim to provide a middle ground by enabling the verification of consensus results across multiple blockchain ecosystems. For example, users can stake Ethereum (ETH) on Symbiotic, and institutions developing applications on Solana can utilize this validation power. Although the execution architecture is different, the security layer is the same, simplifying validation processes. This approach could support various enterprise applications, including liquidity protocols, cross-chain bridges, and oracle systems, without requiring separate verification infrastructure for each blockchain. The Crypto Investor Blueprint: A 5-Day Course On Bagholding, Insider Front-Runs, and Missing Alpha Nice 😎 Your first lesson is on the way. Please add [email protected] to your email whitelist. The unified model creates native connectivity between supported blockchains, potentially simplifying multi-chain deployment for institutions exploring blockchain integration strategies.

Zero Fees + 500x Leverage: Understanding Avantis, the Largest Derivatives Exchange on Base

Zero Fees + 500x Leverage: Understanding Avantis, the Largest Derivatives Exchange on Base

Source: Alea Research Daily Newsletter Compiled by: Zhou, ChainCatcher Synthetic derivatives, decentralized oracles, and composable liquidity protocols enable traders to access everything from Bitcoin and ETH to gold and FX using stablecoin collateral. Since Avantis launched on the mainnet in February 2024, it has become the largest derivatives exchange on Base and the largest DEX in the RWA trading and market making field. The protocol has processed over $18 billion in cumulative trading volume and executed over 2 million trades for over 38,500 traders. With $23 million in TVL across 25,000+ LPs and over 80 markets, Avantis is solidifying its position as a hub for perps. This article will explore Universal Leverage, Avantis's architecture, and the launch of $AVNT. About Avantis Avantis is a perps DEX that allows users to trade cryptocurrencies, forex, commodities, and indices using stablecoin collateral. The protocol abstracts away individual order books and instead builds a “universal leverage layer” where any asset with a reliable price feed can be listed. Synthetic leverage is achieved through a USDC-based liquidity vault that acts as the counterparty for all trades, enabling capital-efficient exposure to multiple markets. Traders can choose up to 500x leverage, allowing them to express directional views with minimal capital, while liquidity providers (LPs) earn a yield by providing USDC to support their positions. Avantis distinguishes itself from other perpetual swap exchanges in that users can trade non-crypto markets like the Japanese Yen, gold, and US stock indices alongside BTC or ETH. The protocol's design also supports features like zero trading fees, loss rebates, and positive slippage, aligning incentives between traders and limited partners by returning a portion of fees or profits to users when they improve the protocol's risk profile. Avantis Architecture At its core, Avantis is a capital-efficient synthetic engine. Traders use the protocol's interface to open positions on supported assets. Instead of matching orders in an order book, Avantis pairs each trader with a USDC vault that takes the other side of the trade. This vault aggregates deposits from thousands of limited partners and acts as a single counterparty. This structure allows the protocol to offer deep liquidity across many markets without requiring separate liquidity pools for each pair, enabling Avantis to list over 80 markets, including 22 RWA assets. Avantis introduces risk tranches and time-lock parameters so that LPs can choose their preferred exposure. LPs can passively deposit in the senior tranche or take more risk in the junior tranche, which has higher return potential but also absorbs a greater share of losses. Additionally, LPs can choose a time lock (e.g., 30 or 90 days) to control the duration of their capital commitment, with longer locks incurring more fees. This design mimics the centralized liquidity model of Uniswap v3 while applying it to the risk management of perps exchanges. Trader <> LP Alignment Avantis' innovative mechanism further aligns the interests of traders and LPs. Loss Rebates: Traders who take the opposite side of open interest (helping balance the platform’s long/short skew) can receive up to 20% loss rebates. This encourages traders to arbitrage open interest and stabilize LP exposure. Positive Slippage: When a trader's order reduces the vault's risk (e.g., closing out a heavily long position), Avantis offers an entry price above the Mark Price. This "better-than-market" execution rewards traders for helping to balance flows. Zero Trading Fees: Avantis pioneered a product where traders pay no fees to open, close, or borrow positions. Instead, they pay only a portion of their profits when closing a winning trade. Available for $BTC, $SOL, and $ETH, with leverage up to 250x, this tool is popular with scalpers and high-frequency traders. Advanced Risk Management: LPs can act as passive lenders or active market makers by selecting risk tranches and time locks. Each tranche has its own share of fees and potential losses, enabling LPs to control risk and return. $AVNT: Token Issuance and Token Economics To facilitate its next phase of growth, Avantis has launched $AVNT, a utility and governance token. $AVNT has multiple functions: Security and Staking: Holders can stake $AVNT in the Avantis Security Module to support the USDC vault during periods of extreme market volatility. Stakers receive $AVNT rewards and discounted trading fees. Community Rewards: 50.1% of the total 1 billion token supply is reserved for traders, liquidity providers, referrers, and builders who contribute to Avantis. Airdrops (12.5% of the supply) will reward protocol activity starting in February 2024, while on-chain incentives (28.6%) will fund future XP seasons and community contributions. Builder and ecosystem grants (9%) will support the creation of new front-ends and trading tools, such as AI agents and Telegram bots. Governance: Token holders will be able to propose and vote on protocol decisions, ranging from asset listings and fee structures to buyback programs and cross-chain deployments. The remaining 49.9% of the supply is distributed as follows: Team (13.3%) Investors (26.61%) Avantis Foundation (4%) Liquidity reserve (6%)

Cardano Founder Says Chainlink Quoted Them An ‘Absurd Price’, Here’s Why

Cardano Founder Says Chainlink Quoted Them An ‘Absurd Price’, Here’s Why

Cardano’s founder, Charles Hoskinson, has clarified why the blockchain platform was excluded from a prominent US government initiative meant to publish official economic data on public blockchains. Blockchain networks like Ethereum, Solana, Avalanche, and Optimism made the cut; Cardano didn’t. Hoskinson revealed during a YouTube AMA that the reason wasn’t technical or regulatory, but it was grounded in economics. Specifically, he said the integration fee quoted by Oracle specialist Chainlink was absurd, which made Cardano’s participation really unfeasible. Chainlink’s Absurd Fee As one of the biggest blockchain ecosystems, Cardano’s inability to participate in the US government’s recent blockchain initiative to bring macroeconomic data onto the blockchain took many crypto participants by surprise. However, while speaking at a recent surprise AMA on his YouTube channel, Cardano founder Charles Hoskinson says the reason boils down to money.  Related Reading: Is XRP Coming To Cardano? Founder Sparks Speculation After Midnight Airdrop According to Hoskinson, the main reason was due to its pending partnership with Chainlink’s oracle integration, which is yet to be finalised because of the absurd fee charged by Chainlink. Hoskinson did not shy away from strong language: “They gave us an absurd number for integration. I said ‘f– it, we’ll handle it. We’ll figure it out,'” he said. Despite the frustration, he tempered his critique with respect. He described Chainlink co-founder Sergey Nazarov as “extremely smart” and “a very good businessman”, someone who “sees the future” and, in Hoskinson’s words, is “sitting on a golden egg”.  Chainlink’s oracle solutions are very important for connecting smart contracts to real-world data. As such, Hoskinson’s metaphor acknowledges Chainlink’s powerful position in the blockchain ecosystem.  How It Stalls Cardano’s DeFi Growth Without a cost-effective oracle integration, Cardano’s decentralized finance landscape has struggled to keep pace with other blockchain ecosystems. To put this into perspective, Ethereum’s integration with Chainlink has allowed large inflows into its DeFi ecosystem, with about $13.4 billion in Total Value Locked (TVL) added from between August 2 ($78.222 billion) and August 31 ($91.595 billion), according to data from DeFiLlama. Related Reading: Cardano Price To Rise 300% To $4? Analyst Reveals When Meanwhile, Cardano’s TVL broke below $400 million in August, and daily active addresses have also fallen massively. At the time of writing, Cardano’s TVL is sitting at $367.91 million. The result is a disconnect between Cardano’s on-chain activity and ADA’s price action, which witnessed a steady increase in August alongside the rest of the crypto market. Nonetheless, Hoskinson is still optimistic. Talks with Chainlink are ongoing, and he’s determined to find common ground with Chainlink. He also revealed discussions with the team behind the USD1 stablecoin and hinted at potential collaboration with Aave, which he described as part of a bundle. If USD1 (already launched on Ethereum, BNB, and Tron) comes to Cardano, it could become the ecosystem’s largest stablecoin. Combine that with oracle access and lending support from Chainlink, and Cardano could strengthen its DeFi foundations significantly. At the time of writing, Cardano is trading at $0.8307, up by 1.1% in the past 24 hours. Featured image from Adobe Stock, chart from Tradingview.com

Lido debuts simplified Earn vaults with Veda and Mellow

Lido debuts simplified Earn vaults with Veda and Mellow

The post Lido debuts simplified Earn vaults with Veda and Mellow appeared on BitcoinEthereumNews.com. Lido has launched Earn, a new tab on stake.lido.fi that surfaces curated strategy vaults aimed at making it easier, and comparatively safer, to put staked ether to work. The first listing, GG Vault (GGV) by Veda Labs, offers one-click access to “blue-chip” DeFi strategies using ETH, WETH, stETH, or wstETH. A second listing, the Decentralised Validator Vault (DVV) implemented by Mellow, is slated to go live in mid-September. Lido says vaults must clear the same security bar as its core protocol, according to Jakov Buratović at the Lido Ecosystem Foundation. “To appear in Lido Earn…all production contracts must be audited by reputable firms before listing, with any material findings addressed,” Buratović told Blockworks.  Live vaults maintain automated alerts to spot any issues, and “if necessary, onchain pause or kill mechanisms can be triggered to halt the vault operation,” he said. While the foundation works to minimize risk for depositors, Buratović notes, they disclaim any liability for potential losses. Fees are straightforward at launch. “Specifically for GGV, there is a 1% platform fee split between Veda and the Lido DAO, consistent with rates seen in other DeFi vaults,” Buratović said. On the UX side, users receive an ERC-20 deposit token which accrues value, similar to wstETH — the non-rebasing form of stETH which is widely used in DeFi. Withdrawals are made in wstETH and, for now, Lido is not optimizing for secondary markets of the vault tokens. The liquid staking provider currently has about $38 billion in ETH deposits, representing nearly 61% of staked ether, according to Blockworks Research’s latest data. Source: Blockworks Research The Mellow alternative The second strategy listed in Earn, DVV, is built on Mellow’s modular vault architecture and introduces a different approach — this time centered on validator decentralization. Each strategy is boxed into an isolated “Subvault,”…

CFTC grants Polymarket green light for US return through regulatory approval

CFTC grants Polymarket green light for US return through regulatory approval

The post CFTC grants Polymarket green light for US return through regulatory approval appeared on BitcoinEthereumNews.com. The Commodity Futures Trading Commission (CFTC) granted regulatory approval for prediction market platform Polymarket to resume US operations through a no-action letter issued to QCX LLC on Sept. 3. The CFTC’s Division of Market Oversight and the Division of Clearing and Risk announced that they will not pursue enforcement action against QCX LLC or QC Clearing LLC regarding swap data reporting and record-keeping requirements for event contracts. Regulatory greenlight The letter applies only to narrow circumstances and mirrors similar regulatory relief granted to other designated contract markets. The approval enables Polymarket to operate event contracts while maintaining compliance with federal derivatives regulations through its QCX partnership structure. Polymarket CEO Shayne Coplan celebrated the development on social media, crediting the Commission for “impressive work” and noting the process was completed in “record timing.” Coplan indicated US operations would launch soon, posting “stay tuned” to his announcement. The regulatory green light marks a return for Polymarket, which ceased US operations in 2022 following CFTC settlement over unregistered derivatives trading. The platform paid $1.4 million to resolve those charges and blocked American users from accessing its prediction markets. Polymarket accelerated its efforts for a US return in July, when the US Department of Justice and the CFTC concluded the probe into the prediction market. Less than a week later, Polymarket acquired QCX in a $112 million deal. On Aug. 26, Donald Trump Jr. joined Polymarket’s advisory board amid an undisclosed investment from its venture capital firm 1789 Capital.
