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.

Inside Bitcoin’s 24 hour race to survive a global internet blackout

Inside Bitcoin’s 24 hour race to survive a global internet blackout

The post Inside Bitcoin’s 24 hour race to survive a global internet blackout appeared on BitcoinEthereumNews.com. Imagine the world’s internet backbone collapsing in a day. Whether it’s due to human error, a catastrophic software bug, a rogue computer virus, or outright kinetic warfare, what happens to Bitcoin if the physical internet exchange hubs that connect the world suddenly go dark? If Frankfurt, London, Virginia, Singapore, and Marseille were to go offline simultaneously, Bitcoin splits into three partitions. Traffic across the Atlantic, the Mediterranean, and the main trans-Pacific routes would stall, leaving the Americas, Europe, Africa, the Middle East, and Asia and Oceania to view history separately until links are restored. Block production continues inside each partition according to the hashrate that remains reachable. With a 10-minute global target, a region that holds 45 percent of the hashrate produces roughly 2.7 blocks per hour, 35 percent produces about 2.1 blocks, and 20 percent produces about 1.2 blocks. Because nodes cannot exchange headers or transactions across partitions, each region advances a valid chain unaware of the others. The result is a natural fork depth that grows with time and with the distribution of hashrate. The partitioned cadence makes the divergence mechanical. Let’s assign rough hashrate averages to each region. For our modeling, we will use 45%, 35%, and 20% as our baseline distribution for the Americas, Asia and Oceania, and Europe and Africa, respectively. An Americas cohort would add about six blocks every two hours, while Asia and Oceania would roughly add four to five blocks per hour, and Europe and Africa would add around two to three blocks per hour. After one hour, the ledgers would already differ by double-digit blocks. After half a day, gaps expand into the low hundreds. After a full day, the chains differ by hundreds of blocks, which is beyond the range of routine reorganizations and forces services to treat regional confirmations…

Ionex Adds Orbs’ Perpetual Hub Ultra, Expanding High-Performance Perpetual Trading on Plasma

Ionex Adds Orbs’ Perpetual Hub Ultra, Expanding High-Performance Perpetual Trading on Plasma

Orbs’ Perpetual Hub Ultra has been integrated into Ionex, the newly launched decentralized exchange by DefiZoo, bringing institutional-grade perpetual futures trading to the Plasma ecosystem. The move positions Orbs’ Layer-3 technology as a plug-and-play solution for DEXs looking to expand into derivatives without sacrificing speed or capital efficiency. The integration gives Ionex users access to what Orbs calls a fully managed, modular perps stack: deep liquidity, customizable leverage and low-latency execution. Built on Orbs’ Layer-3 infrastructure and developed in collaboration with Symm.io, Perpetual Hub Ultra supplies the back-end plumbing a decentralized platform needs to run high-performance perpetuals, hedging, liquidation, oracles and a professional-grade user interface are included out of the box. “Perpetual Hub Ultra makes it possible for any DEX to offer customized, high-performance perps trading experience, with full white label stack out of the box,” said Ran Hammer, Vice President of Business Development at Orbs. “By integrating with Ionex, we are enabling a new standard for decentralized markets that rivals centralized trading in both speed and efficiency.” Strengthening Layer-3 Trading Infrastructure Ultra is designed for scalability and capital efficiency, allowing liquidity routing from both on-chain and off-chain sources, including major centralized exchanges. That dual sourcing aims to deliver deep execution to DEXs and aggregators without requiring specialized chains or complex engineering work. The architecture mirrors the intent-based trading models that have gained traction in decentralized spot markets, now applied to perpetuals, so decentralized venues can better compete with centralized exchanges on performance, flexibility and user experience. Ionex itself is pitched as more than a conventional DEX. Operating entirely on Plasma, the platform serves as a liquidity marketplace and trading hub with features such as seamless token swaps, liquidity provision that earns $INX rewards, and DAO-driven governance for emission control. Its MetaDEX module unifies spot and perpetual markets, while the MetaPerp, a new category of self-custodial perpetuals powered by Orbs, promises CeFi-grade execution with up to 60× leverage and sub-100ms fills. The integration reinforces Orbs’ growing footprint in the derivatives layer of DeFi. Orbs has already powered several deployments of Perpetual Hub, and Perpetual Hub Ultra represents an evolution intended to lower the barrier for DEXs to offer professional-grade perps. Orbs describes itself as a decentralized Layer-3 blockchain purpose-built for advanced on-chain trading; leveraging Proof-of-Stake consensus, it provides a supplementary execution layer for complex logic and scripts beyond native smart contract capabilities. For Ionex, the partnership with Orbs and Symm.io looks to accelerate its goal of combining aggregator liquidity, zero-fee USDT transfers and a tri-token incentive model, $INX, veINX and oINX, into a single trading experience. By bundling spot and perpetual liquidity under the MetaDEX umbrella, Ionex aims to appeal to traders who want deep execution and a seamless, self-custodial interface. Together, the companies say the integration marks another milestone in the migration of complex financial products onto blockchain infrastructure. Perpetual Hub Ultra’s plug-and-play approach seeks to make sophisticated derivatives accessible to a new generation of decentralized trading venues while bolstering Orbs’ claim as the leading Layer-3 infrastructure provider for turnkey derivatives in DeFi.

When DAO meets homeowners' committee: How does the "happiness index" under Merkel's tree reshape grassroots governance?

When DAO meets homeowners' committee: How does the "happiness index" under Merkel's tree reshape grassroots governance?

Market predictions are all the rage lately, so I'd like to propose a new concept that might support some really cool experiments. The idea wasn't my original creation; it came from a rather fantastical research paper. The author, Ralph Merkle, one of the "founding fathers" of crypto, radically proposed using prediction markets to govern countries. And this very paper was published in the journal Cryonics. When I first read it, I only found the concept interesting, but its practicality was zero. Recently, upon rereading it, I suddenly realized that if the scenario is not limited to national governance, it is actually a universally applicable solution with considerable operability. If you don't remember who Merkel is, he is the co-inventor of "asymmetric encryption" (public-private key) and the inventor of "Merkle Tree". Every transaction on the blockchain relies on public and private keys. Each Bitcoin block is imprinted with a Merkle tree "root" (used to efficiently prove that all transactions within the block are complete and have not been tampered with). Thesis Background Merkel launched a fierce attack, arguing that "one person, one vote" democracy is a complete mess. She claimed that this system forces most ordinary people—who lack understanding of economics, political science, and sociology, and are misled by the media—to vote on extremely complex bills. This is not only unfair, but also inevitably leads to mediocre and poor decision-making. The governance machine designed in the paper (which Merkel calls DAO democracy) operates on a logic completely opposite to that of traditional voting systems. Traditional voting is "decision first, results later" (people vote for option A, then bear the consequences, good or bad). Merkel's machine is "predicting results first, then making decisions." The machine's operation relies on two core components: 1. The sole objective: the citizens' "happiness index" The machine has a unique and immutable ultimate goal (protected by a DAO contract), which is called the "happiness index". This index is obtained by all citizens themselves through "post-hoc scoring". Every year, all citizens score the past year, for example, from 0 (worst) to 1 (best). The average of all scores is the "annual happiness index" for that year. This score is the only metric the system pursues. 2. Decision Engine: Predicting Markets With a single objective, decision-making becomes simple. When someone submits a new bill (such as "whether to build a new high-speed rail line"), the system doesn't initiate a vote; instead, it automatically opens two parallel prediction markets: Market A: What is your prediction for the long-term "happiness index" if the bill passes? Market B: What is the predicted long-term "happiness index" if nothing is done? Then, the machine waits for the prediction period to end and then looks at the prices in markets A and B. If the price in market A is higher than that in market B (the prediction is 0.72), the machine automatically determines that the bill should pass. Otherwise, it should be rejected. The ingenuity of the design The brilliance of this design lies in transforming "decision-making" from a "political problem" rife with bias and populism into an "information problem" that rewards rationality and professionalism. In prediction markets, someone who makes random bets ("I don't care, I just hate high-speed rail!") will lose money. Those who truly profit are the ones who can most accurately predict whether "this bill will actually make most people happier in the future." It cleverly utilizes "greed," allowing the voice of reason, rather than the loudest voice, to dominate decision-making. Of course, the specific mechanisms are far more complex than I've explained; those interested can refer to the paper themselves. Back to reality Personally, I think the feasibility of using this machine to govern a country is zero. Merkel herself also mentioned many difficult problems: such as how to prevent the system from choosing an absurd solution like "giving everyone hallucinogens" in order to pursue high scores? And how to deal with a bill that "has a 10% chance of causing the end of the world"? Besides these technical difficulties, political friction also means that no political system can possibly apply this solution. However, if it's not about national governance, but rather some narrower areas, I think there's a possibility that, through appropriate abstraction and carefully crafted conditions, it's likely to be a viable path. To give a simple example The neighborhood's "owners' committee" made a decision. Those who value appearances wanted to spend 100,000 yuan to build a useless fountain. Those who prioritize their basic needs wanted to use the money to repair the leaky roof. In traditional voting, this matter ultimately becomes a matter of "the loudest voice" rather than "the right person" winning. Applying the "Merkel machine": Objective: Annual homeowner satisfaction. Two proposals were submitted to let prediction markets determine pricing: Market A: What is your prediction for the average "satisfaction" score at the end of the year if the fountain is repaired? Market B: What is the predicted average "satisfaction" score at the end of the year if the roof is repaired? Homeowners whose homes are leaking (the true "experts" on this issue) would only have one vote in a traditional poll. But in this market, they are 100% certain that fixing the roof will improve satisfaction, so they dare to bet heavily on "Market B". The system sees that the price (predicted satisfaction) of "Market B" is higher than that of "Market A" and automatically approves the roof repair proposal. Settlement: At the end of the year, all homeowners gave their ratings. Those whose homes were no longer leaking gave them high scores. The people who bet on the roof repairs won the money that those who bet on the fountain repairs had. The actual application design may be more complex than this, but the basic logic is as follows. Essentially, it involves entrusting a highly subjective and open community decision-making process to an equally open, financially driven predictive machine for arbitration. The principle of one person, one vote in democracy hasn't disappeared; it has simply taken a different form to keep the entire mechanism running. This product could even become a "governance as a service" platform. The platform itself does not determine any KPIs or schemes; it only provides a neutral "toolbox" (such as DAO contracts, prediction markets, and oracles). Any organization, from industry associations to open-source communities, can register to use it and then "insert" its own unique KPIs (such as "satisfaction" or "downloads") and specific proposals. The platform is only responsible for running the market and returning the "optimal solution." It acts like a neutral "referee," providing a plug-and-play decision-making machine for all organizations that need to make difficult, transparent decisions.
