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.

AI agents spend just $1.22 to shatter smart contract security exposing a terrifying economic reality

AI agents spend just $1.22 to shatter smart contract security exposing a terrifying economic reality

Anthropic’s Frontier Red Team spent the past year teaching AI agents to behave like professional DeFi attackers. The agents learned to fork blockchains, write exploit scripts, drain liquidity pools, and pocket the proceeds, all in Docker containers where no real funds were at risk. On Dec. 1, the team published results that should recalibrate how […] The post AI agents spend just $1.22 to shatter smart contract security exposing a terrifying economic reality appeared first on CryptoSlate.

Ethereum’s Fusaka upgrade lands today

Ethereum’s Fusaka upgrade lands today

The post Ethereum’s Fusaka upgrade lands today appeared on BitcoinEthereumNews.com. This is a segment from the 0xResearch newsletter. To read full editions, subscribe. Today markets leaned decisively risk-on, with crypto leading the move while traditional assets stayed muted. Ethereum’s Fusaka upgrade arrived with PeerDAS, BPO hard forks, and the under-discussed EIP-7918, which together may finally restore deflationary pressure on ETH. On the thematic front, Sui is making an aggressive full-stack push into robotics, positioning onchain coordination, settlement and telemetry as critical primitives for a coming wave of real-world machines. Indices Markets leaned firmly risk-on, with crypto broadly outperforming traditional assets. BTC (+5.8%) sat mid-pack, while equities were muted. The S&P 500 (+0.3%) and Nasdaq 100 (+0.9%) barely budged. Gold (-0.3%) slipped, and crypto miners were the clear outlier to the downside (-8.7%), suggesting profit-taking and sensitivity to BTC’s consolidation. The crypto sector breadth was exceptionally strong. Oracles, lending and the broader Ethereum ecosystem led the board, signaling a clear rotation back into core infrastructure and high-utilization protocols. DeFi, Modular, the Solana ecosystem, and perps followed close behind with similarly solid showings, pointing to broad appetite for beta across liquid alt sectors. Lower down the stack, L2s, AI plays, launchpads and gaming tokens all moved higher, while more speculative areas like memes lagged. The only clear pockets of weakness were crypto equities and miners especially, which saw meaningful pullbacks. The move fits with improving sentiment as macro headwinds ease. Yields stabilized, liquidity indicators firmed, and positioning metrics suggest investors are adding risk after a muted stretch. Strong rebounds in infra sectors imply expectations for higher onchain activity and potential catalysts from upcoming protocol upgrades. Looking ahead, attention turns to macro prints later this week, which could test the durability of this risk-on tone. Volatility remains compressed, but with crypto sector dispersion widening, traders should expect sharper rotations as narratives evolve. Market…

USD softens as Trump signals Hassett for Fed Chair – Scotiabank

USD softens as Trump signals Hassett for Fed Chair – Scotiabank

The post USD softens as Trump signals Hassett for Fed Chair – Scotiabank appeared on BitcoinEthereumNews.com. The US Dollar (USD) twitched nervously yesterday as President Trump referred to CEA head Hassett as the ‘potential’ Fed chair. This morning sees the USD broadly lower and the US yield curve a little steeper as markets mull the strengthening prospect of a Hassett-led Fed, Scotiabank’s Chief FX Strategists Shaun Osborne and Eric Theoret report. DXY pressured as yield advantage continues to shrink “Spot moves are not all that significant on the face of it; the Scandies and the pound lead gains on the session, rising between 0.5-0.6% but the DXY is pinned back to recent lows and looks prone to more losses. The DXY’s weighted yield spread over its major currency peers has been steadily shrinking in recent months while the index itself has rallied since September. The narrowing yield advantage adds to building bearish pressure on the USD.” “Asian and European stocks are mixed while US equity futures are higher on the session. Risk sentiment has steadied since the late November volatility in tech stocks but underlying worries persist. Oracle Corp’s credit default swaps continue to widen, reaching a little beyond the previous peak seen in 2022 (implying a cumulative 5Y probability of default of a little over 10%).” “On the charts, DXY losses have dumped the index back to the 99.0 support zone. This is the neckline trigger for a double top pattern that developed through November at 100.4. A break lower targets a drop to 97.6.” Source: https://www.fxstreet.com/news/usd-softens-as-trump-signals-hassett-for-fed-chair-scotiabank-202512031426

Grayscale Launches First US Chainlink ETF as DeFi Degens Rush to PEPENODE for Upside

Grayscale Launches First US Chainlink ETF as DeFi Degens Rush to PEPENODE for Upside

The post Grayscale Launches First US Chainlink ETF as DeFi Degens Rush to PEPENODE for Upside appeared on BitcoinEthereumNews.com. Crypto Projects Takeaways: Chainlink’s first US ETF underscores how traditional finance is moving deeper into DeFi infrastructure while retail traders explore higher-risk, higher-upside niches. Gamified ‘mine-to-earn’ mechanics are emerging as a way to revive mining’s participatory ethos without hardware costs or access to industrial-scale power. Memecoins are evolving into full-stack experiences with dashboards, node systems, and layered incentives rather than relying solely on viral branding and community hype. PEPENODE’s mine-to-earn design uses a Virtual Mining System and tiered node rewards to tackle boring mining models and weak early incentives. The approval of Grayscale’s first US Chainlink ETF on NYSE Arca marks another step in bringing oracle infrastructure into mainstream portfolios. After spot Bitcoin and Ethereum ETFs pulled billions in inflows, a Chainlink vehicle lets traditional investors get direct, regulated exposure to DeFi’s data backbone. For you, that’s a signal about where the market is heading: real-world money is moving deeper into crypto’s infrastructure layer. As institutions chase compliant yields and blue-chip narratives, retail traders are increasingly rotating further out along the risk curve, hunting for asymmetric upside in niches that ETFs will never touch. That split is already visible on-chain. While majors consolidate and ETFs soak up supply, meme coins and experimental token models are where traders test new incentive designs. In 2021, it was dog-themed tokens; in 2023, it was points and airdrop farming; today, it’s ‘click-to-earn,’ ‘tap-to-mine,’ and other gamified reward systems that don’t require a server rack in your basement. This is where PEPENODE comes in. As the world’s first mine-to-earn memecoin, it leans into that speculative energy but wraps it in a virtual mining system instead of hash power and electricity bills. If ETFs are crypto’s bond desk, PEPENODE is the degen arcade at the other end of the floor, built for people who actually want…
