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.

What is Uniswap v4? A Short Technical Breakdown

What is Uniswap v4? A Short Technical Breakdown

Uniswap has been the backbone of decentralized trading, replacing traditional order books with Automated Market Makers (AMMs). At the heart of this model are liquidity pools, where users supply tokens and earn fees in return. With each upgrade, Uniswap has aimed to improve efficiency, reduce costs, and create a better user experience. Now, with Uniswap v4, the protocol introduces a leap forward with: Singleton Architecture — consolidating all pools into a single contract to cut costs and reduce fragmentation. Customizable Hooks — allowing developers to build unique pool behaviors, from dynamic fees to on-chain strategies. Flash Accounting — settling balances only once per transaction for massive gas savings. Native ETH Support — streamlining ETH trading without wrappers. These innovations mark a turning point in how decentralized exchanges (DEXs) can scale and evolve. From v1 to v4: The Evolution Uniswap v1 (2018): Introduced the AMM model, enabling ETH ↔ ERC20 swaps but requiring ETH as a bridge for ERC20 ↔ ERC20 trades. Uniswap v2 (2020): Added ERC20 pools, flash swaps, and price oracles, but still lacked capital efficiency. Uniswap v3 (2021): Brought concentrated liquidity, letting LPs define price ranges, improving efficiency but increasing complexity. Uniswap v4 (2025): Introduces singleton contracts, hooks, and flash accounting, further boosting efficiency and flexibility. Impermanent Loss (IL) in Brief Liquidity providers risk impermanent loss when token prices move differently than if they had just held them. For example, providing ETH + USDC to a pool may yield fewer profits than simply holding both if ETH’s price doubles. LPs accept this trade-off because trading fees often offset IL. Uniswap v4 doesn’t eliminate IL entirely but provides new tools through hooks that could help reduce its impact in the future. Liquidity in v4 In v4, liquidity is managed by a singleton PoolManager. Unlike earlier versions where each pool had a separate contract, all pools now live under one roof. This structure makes liquidity management more efficient, reduces gas costs, and enables extensible behaviors through hooks. Hooks: The Game-Changer Hooks are perhaps the biggest innovation in Uniswap v4. They let developers customize pool behavior at critical points (before/after swaps, liquidity changes, etc.). Some applications include: Dynamic fee adjustments On-chain limit orders Auto-compounding yields MEV protection This flexibility turns Uniswap into a developer platform for building new financial primitives, far beyond standard AMM models. Uniswap v4 introduces powerful upgrades, singleton architecture, hooks, flash accounting, and ETH-native support that make DeFi trading more efficient and customizable than ever. At QuillAudits, we recognize how innovations like these raise the bar for decentralized exchanges while also demanding rigorous smart contract security audits to ensure reliability, cost savings, and developer flexibility.

Nvidia said two unnamed buyers made up 39% of its Q2 revenue

Nvidia said two unnamed buyers made up 39% of its Q2 revenue

The post Nvidia said two unnamed buyers made up 39% of its Q2 revenue appeared on BitcoinEthereumNews.com. Nvidia disclosed on Wednesday that just two unnamed customers were responsible for 39% of its total revenue in the second quarter of its fiscal year, a detail buried inside a regulatory filing submitted to the U.S. Securities and Exchange Commission. The company listed the buyers simply as “Customer A” and “Customer B,” with the first accounting for 23% and the second for 16% of Nvidia’s sales during the three-month period ending in July. Combined, they nearly controlled $6 billion of the chipmaker’s Q2 topline. That level of concentration is significantly higher than the same quarter last year, when Nvidia’s two biggest customers made up 14% and 11%. The spike is now fueling deeper scrutiny into who exactly is behind the massive surge in AI chip spending, and what that means for Nvidia’s revenue stability going forward. Despite repeated speculation that cloud heavyweights like Amazon, Microsoft, Google, or Oracle might be behind the numbers, Nvidia declined to name the clients. Nvidia keeps mystery buyers hidden behind layers of supply chain In the filing, Nvidia described Customer A and Customer B as “direct customers.” That doesn’t mean they’re using the chips themselves. These direct customers are firms that purchase Nvidia’s hardware to assemble complete systems or boards, which are then sold to the actual end users; like cloud companies, government agencies, and corporate enterprises. The list of potential intermediaries includes original design manufacturers and equipment builders such as Foxconn, Quanta, and big system integrators like Dell. Nvidia also acknowledged having indirect customers, the companies who eventually use the systems but don’t buy chips directly from Nvidia. These are the cloud infrastructure players, tech firms, and large organizations building internal AI platforms. The company said it can only estimate how much of its revenue comes from indirect buyers, using purchase orders and internal…

Ethereum exit queue hits Record $5B ETH, raising Sell Pressure concerns

Ethereum exit queue hits Record $5B ETH, raising Sell Pressure concerns

The post Ethereum exit queue hits Record $5B ETH, raising Sell Pressure concerns appeared on BitcoinEthereumNews.com. Ethereum is seeing the largest validator exodus in crypto history, with over 1 million Ether tokens currently waiting to be withdrawn from staking through Ethereum’s proof-of-stake (PoS) network. Ethereum’s exit queue surpassed 1 million Ether (ETH) worth $4.96 billion on Thursday. This marks the amount of Ether set for withdrawal by the network’s validators, who are responsible for adding new blocks and verifying transactions in proposed blocks, playing a vital role in the functioning of the blockchain network. The mass exodus has extended the validator exit waiting time to a record 18 days and 16 hours, according to blockchain data from validatorqueue.com. While this does not mean that all the validators are looking to sell their holdings, a significant portion of the almost $5 billion may be sold to lock in profits, considering that Ether has risen 72% over the past three months. Ether validator queue. Source: validatorqueue.com “The exit queue hitting 1 million ETH reflects healthy market dynamics rather than a cause for concern,” Marcin Kazmierczak, co-founder of RedStone blockchain oracle firm, told Cointelegraph, adding: “What’s crucial to understand is that these exits pale in comparison to the institutional capital flowing into Ethereum.” The “unprecedented demand” from public vehicles such as treasury firms and exchange-traded funds means that the validator sales are “easily absorbed by this institutional appetite,” he said.

Base Overtakes Solana in NFT Volume as Zora Drives Minting Frenzy

Base Overtakes Solana in NFT Volume as Zora Drives Minting Frenzy

The post Base Overtakes Solana in NFT Volume as Zora Drives Minting Frenzy appeared on BitcoinEthereumNews.com. With millions of mints and $122 million in trading volume, Base has quietly emerged as a go-to platform for Web3 creators. Coinbase’s Layer-2 network, Base, has become one of the most active blockchain ecosystems by NFT trading volume, surpassing Solana and Abstract. DappRadar’s blockchain analyst Sara Gherghelas said in a recent research report that Base has become a popular place for creators, thanks to cheap mints, creator-friendly tools, and “speculation around a potential airdrop.” Top Blockchains by NFT Volume “Base NFTs hit $122M in trading volume and 6.7M sales in 2025, with June marking a breakout moment (+336% MoM volume),” Gherghelas noted. The surge has been fueled by top collections such as DX Terminal, Onchain Gaias, Oracle Patron, Based Punks, and Get Based, blending retro-futuristic art, interactive gameplay, and, in the case of Onchain Gaias, the ability for holders to train AI-enabled agents across Web3 ecosystems. Behind the Numbers The main driver behind Base’s NFT boom is Zora, an open-source NFT protocol that lets creators launch low-cost NFTs and drops on Base for less than one U.S. dollar, while also offering an ERC-20 layer for creator tokens. “Since July alone, Zora on Base has recorded 1.6 million tokens minted, generating $470 million in trading volume and $3.4 million in creator royalties,” Gherghelas wrote. Data from DefiLlama shows that starting in July, Zora’s revenue jumped to $4.7 million, marking a more than 312,000% increase compared to Q4 2024. On the marketplace front, OpenSea has emerged as the leader on Base, with Gherghelas attributing this to the fact that the marketplace was an early Base supporter. NFT Volume by Marketplace Amid the recent uptick in NFT activity, OpenSea has overtaken Blur over the past 90 days, with trading volume of $389 million, compared to Blur’s $312 million, according to Token Terminal.
