Gate Officially Integrates Polymarket Directly into its App 

0

Gate.com has officially integrated Polymarket, the popular decentralized prediction market platform. This makes Gate the first centralized exchange (CEX) to embed Polymarket directly into its app.

A dedicated “Polymarket” entry in the Gate App requires version 8.12.5 or higher. Users can reach it via the Alpha section on the homepage. Trade Yes/No shares on real-world events in categories like sports, finance, crypto, politics, and global trends.

Outcomes settle automatically into stablecoins once resolved via Polymarket’s mechanisms, such as UMA’s Optimistic Oracle. Dual modes for accessibility: Prediction mode: Simplified interface ideal for beginners. Advanced tools including order books, candlestick charts, limit orders, and more for experienced traders.

Dual On-Ramps (lowering barriers): Use USDT directly from your Gate spot/futures account (no need for on-chain actions). Or connect a Web3 wallet with USDC on the Polygon network for native on-chain experience. Retains Polymarket’s decentralized prediction mechanics while adding CEX conveniences like unified asset management and faster execution.

This integration aims to bring Polymarket’s high-volume event-driven trading which saw billions in volume previously to Gate’s large user base in a seamless way. Gate is running a limited-time campaign with a 1,000 GT prize pool for users who submit high-value prediction market proposals on trending topics.

Top proposals get rewarded, plus there’s first-trade insurance and up to 100 USDT for providing feedback. Prediction markets have gained mainstream traction, and this move bridges DeFi-style betting with familiar CEX usability. It could attract new users interested in “information markets” while boosting liquidity and engagement on Gate.

Polymarket’s Optimistic Oracle is the decentralized mechanism that settles (resolves) its prediction markets by determining the real-world outcome of events (e.g., “Will Candidate X win the election?” or “Will this sports team win?”).

It is powered by UMA’s Optimistic Oracle often abbreviated as OO or OOv2/Managed OOv2 in recent versions, a flexible oracle system designed for “long-tail” or subjective data that doesn’t fit neatly into automated price feeds.

The system is called optimistic because it assumes any proposed outcome is correct by default — unless someone actively disputes it during a short challenge window. This makes resolution fast and cheap for the vast majority of markets. It relies on economic incentives (bonds and rewards) rather than constant computation or trusted third parties.

Once the event concludes or the market’s resolution date arrives, anyone can propose the outcome. This bond acts as “skin in the game.” If the proposal is correct and undisputed, the proposer gets the bond back plus a reward. If wrong or disputed successfully, they lose the entire bond.

A short window opens often 2 hours for initial proposals. Anyone can dispute by posting their own bond if they believe the proposal is incorrect. If no one disputes, the proposal is automatically accepted as truth. The market settles, and winning shares can be redeemed for $1 USDC each (losing shares become worthless).

The first dispute may trigger a reset (new proposal required) to filter out frivolous challenges. If a second valid dispute occurs, it escalates to UMA’s Data Verification Mechanism (DVM). UMA token holders vote on the correct outcome (voting lasts ~48 hours, weighted by staked UMA tokens).

Voters who align with the majority win rewards; those on the losing side can be penalized (slashing). The vote result determines the final settlement. Once resolved, Polymarket’s smart contracts via the UMA CTF Adapter automatically pay out to holders of the winning outcome tokens.

Most markets resolve in hours with no human intervention or voting. Handles arbitrary real-world questions in natural language (not just prices), unlike rigid oracles like Chainlink price feeds. Anyone can propose or dispute — no central authority controls outcomes.

Bonds deter bad proposals; voting rewards honest participation and uses game theory (Schelling point) to align voters with truth. Disputes are rare, so gas and time costs stay low. Polymarket also maintains market integrity guidelines and sometimes provides clarifications, but the actual on-chain resolution is handled by the oracle.

An Optimistic Truth Bot has been introduced by UMA to speed up accurate proposals. Like any decentralized system, it isn’t perfect — rare high-stakes disputes can lead to controversial votes, and there have been historical cases of alleged manipulation. However, the bond + dispute + vote layers provide strong economic security for most use cases.

The Ethereum Foundation Launches Quantum (PQ) Security Hub

0

The Ethereum Foundation (EF) has launched a dedicated public resource hub http://pq.ethereum.org/  for its post-quantum (PQ) security efforts. This marks a major step in consolidating over 8 years of research into a centralized portal with a clear roadmap, technical specs, open-source code, FAQs, and resources for institutions and developers.

Quantum computers could eventually break current elliptic-curve cryptography like ECDSA and BLS signatures used in Ethereum for signatures, commitments, and proofs. Estimates for a “cryptographically relevant” quantum computer (“Q-Day”) cluster around the early-to-mid 2030s. Ethereum is acting proactively to avoid rushed, disruptive changes later. The goal is a smooth migration with no network downtime or loss of user funds.

Vitalik Buterin and EF researchers have highlighted four main areas at risk: Consensus layer — BLS signatures for validator attestations. The PQ work integrates into Ethereum’s broader “strawmap” (a living draft roadmap through ~2029 with forks on a roughly 6-month cadence).

PQ attestations, real-time consensus-layer proofs, and leanVM optimizations (Consensus + Data). Longer term — Full PQ consensus, PQ transactions, and PQ data sampling across all layers. Supporting tech includes: leanSig — A hash-based, quantum-resistant multi-signature scheme using one-time signatures via hash chains + Merkle trees + SNARKs for efficient aggregation replacing BLS.

STARK-based approaches for commitments and aggregation (quantum-resistant and “lean”). Native Account Abstraction — To ease migration away from vulnerable EOA signatures. leanVM and other EVM optimizations for handling heavier PQ proofs efficiently.

The EF has a dedicated Post-Quantum team formalized in early 2026, multiple client teams actively testing on devnets weekly, and plans for workshops including one in Cambridge, UK, in October 2026. This aligns with Ethereum’s 2026 priorities: post-quantum security alongside gas limit increases, blob scaling, and other upgrades. It’s positioned as one of five “north stars” for the protocol.

The approach emphasizes hash-based cryptography for its simplicity, efficiency, and quantum resistance, while maintaining decentralization and performance. The launch has drawn positive attention in the community for its transparency and forward-thinking stance. Ethereum isn’t alone—other chains and projects are also planning PQ migrations—but the EF’s coordinated, public effort stands out.

leanSig is Ethereum’s reference post-quantum, hash-based multi-signature scheme, designed specifically as a drop-in replacement for the current BLS (Boneh-Lynn-Shacham) signature scheme in the consensus layer. It forms a core piece of the “Lean Ethereum” initiative and the broader post-quantum (PQ) roadmap.

The scheme is quantum-resistant by construction, relying solely on the security of cryptographic hash functions immune to Shor’s algorithm, though affected by Grover’s quadratic speedup. It was introduced in a December 2024 IACR paper and refined in a 2025 technical note. A prototypical Rust implementation lives in the leanEthereum GitHub organization.

Ethereum’s proof-of-stake consensus relies heavily on BLS signatures for validator attestations, block proposals, and aggregation. BLS is fast, compact (~48 bytes), and natively aggregatable—but it is not quantum-safe. A cryptographically relevant quantum computer could forge signatures or recover private keys.

Hash-based signatures like XMSS provide a simple, minimal-assumption alternative: security reduces to hash collision/preimage resistance. However, plain XMSS has drawbacks for Ethereum-scale use. leanSig also called leanXMSS in some contexts addresses these by: Optimizing for Ethereum’s consensus constraints.

Enabling efficient SNARK/STARK-based aggregation via leanMultisig to keep aggregate proofs compact and verification fast. leanSig trades larger individual signatures for quantum security and SNARK compatibility, with aggregation restoring scalability. leanSig is built on a generalized XMSS framework using: Tweakable hash functions.

Incomparable encodings (core innovation): Ensures encoded message representations cannot be “upgraded” by an adversary (prevents forgery via partial ordering on codewords). One-time signatures via Winternitz-style hash chains. Merkle trees for turning many one-time keys into a single long-lived public key.

Top-Layer Target Sum Winternitz (TLTSW): Maps to the “top layers” of a hypercube {0,…,w-1}^v for better size-vs-verification-cost tradeoff. Uses a modulo reduction + bijective MapToVertex function. Expected signing retries ?30. Signature includes: randomness ?, one-time signature, and Merkle path for the epoch leaf.

Epoch-based state management (secret key is advanced sequentially; reuse is forbidden). Verification recomputes the leaf public key and checks the Merkle path. Hash-based schemes lack BLS-style algebraic aggregation. leanSig solves this with pqSNARKs via leanMultisig: Each validator produces an individual leanSig.

An aggregator generates a SNARK proof asserting “I know valid signatures from these public keys for this message.” Aggregate “signature” = the SNARK proof (constant or near-constant size, independent of committee size). This keeps gossip/finality efficient. Benchmarks show hundreds-to-thousands of signatures aggregated per second on consumer hardware.

leanSig exemplifies Ethereum’s proactive, research-driven approach to PQ migration—simple hashes, rigorous proofs, and practical engineering for a decentralized future. Development is active (weekly devnets, client teams iterating), with specs and code evolving via community governance.

Central Bank of Nigeria Moves to Ring-Fence Diaspora Dollars, Orders IMTO Operators to Settle FX Remittances in Naira

0

The Central Bank of Nigeria has unveiled a stricter operating framework for international money transfers, ordering all operators to route transactions through designated naira settlement accounts in a move aimed at tightening control over diaspora inflows and reinforcing transparency in the foreign exchange market.

The directive, contained in a March 24 circular signed by the Director of the Trade and Exchange Department, Dr. Musa Nakorji, requires all International Money Transfer Operators (IMTOs) to open and maintain naira settlement accounts with authorized dealer banks. The circular, published on the bank’s website, takes effect from May 1, 2026.

According to the apex bank, the measure is part of a broader effort to “enhance diaspora remittances, strengthen transparency, traceability, and effective monitoring of all transactions.”

Under the new rules, “all IMTOs are hereby directed to open naira settlement accounts and ensure that all transactions are routed strictly through their designated settlement accounts, maintained with Authorized Dealer Banks (ADBs) in Nigeria.” The instruction effectively centralizes the processing of remittance inflows, beneficiary payouts, and related settlements within the formal banking system.

The framework introduces tighter controls on how these accounts are funded. The CBN stated that settlement accounts “shall only be credited with remittance flows and proceeds of foreign exchange conversions by licensed IMTOs (or their agents)” operating within the Nigerian foreign exchange market. IMTOs are permitted to operate multiple accounts across different banks, but must formally designate them and submit details to the regulator, with updates provided periodically.

In a further attempt to standardize the market, the central bank directed operators to anchor pricing to live market data. IMTOs “shall observe real-time market prices from the Bloomberg BMATCH and utilize this as guidance for pricing transactions with their customers and Authorized Dealers,” the circular said. The bank added that the requirement is intended to “improve price discovery, reduce information asymmetry between IMTOs and banks, and encourage increased participation in the official FX market.”

The policy also broadens the role of authorized dealer banks, allowing them to process foreign currency transfers from IMTO settlement accounts to other banks and approved participants, including licensed Bureau De Change operators. This provision is expected to improve liquidity circulation within the official market, which has struggled with fragmented supply and persistent reliance on parallel channels.

The directive pinpoints the regulator’s determination to bring a larger share of Nigeria’s diaspora remittances, one of the country’s most stable sources of foreign exchange, into the formal system. For years, a significant portion of these inflows has bypassed official channels, driven by exchange rate differentials and operational inefficiencies.

The CBN is attempting to close that gap, improve visibility over cross-border flows, and strengthen its ability to manage the naira by enforcing stricter routing and pricing rules. The emphasis on compliance is explicit. Operators are required to maintain detailed transaction records and adhere fully to anti-money laundering, counter-terrorism financing, and counter-proliferation financing standards.

“This directive takes effect from May 1, 2026. Please note and ensure compliance,” the circular stated.

Analysts say the success of the policy will depend much on whether the official market can offer competitive pricing and seamless execution. While tighter oversight may reduce leakages, sustained inflows will depend on user confidence, particularly among diaspora senders who often prioritize speed and exchange rates.

The move comes amid broader external pressures. Global disruptions linked to tensions involving the United States, Israel, and Iran have begun to filter into commodity markets, affecting everything from energy prices to agricultural inputs. Dangote Industries Limited said demand for its fertilizer products has surged amid supply constraints, highlighting how geopolitical shocks are reshaping trade flows and intensifying the need for stable foreign exchange buffers.

Thus, the CBN’s latest directive is part of a continuing effort to assert greater control over currency flows and maintain the relative stability that the naira has recently recorded.

U.S. Judge Says Pentagon May Be Retaliating Against Anthropic Over AI Safety Concerns

0

A federal judge in California suggested on Tuesday that the Pentagon’s unprecedented blacklisting of artificial intelligence firm Anthropic may have been motivated by the company’s public stance on AI safety rather than genuine national security concerns.

The case stems from Anthropic’s lawsuit challenging the Department of Defense’s designation of the company as a “national security supply-chain risk,” a label that effectively blocks it from certain military contracts. The company contends the move violates its constitutional rights, including free speech and due process, after refusing to let its Claude AI software be used for domestic surveillance or autonomous weapons, citing reliability and ethical concerns.

U.S. District Judge Rita Lin, a Biden appointee, said during the hearing in San Francisco that the designation “looks like an attempt to cripple Anthropic” and suggested it may be punitive.

“It looks like DOW is punishing Anthropic for trying to bring public scrutiny to this contract dispute,” she said, referring to the Department of War, President Donald Trump’s rebranding of the Defense Department.

The Anthropic lawsuit, filed on March 9, argues that the Pentagon overstepped its authority by imposing the supply-chain risk label without giving the company an opportunity to respond, in violation of the Fifth Amendment. Anthropic also claims that the move constitutes retaliation for speaking out on AI safety, implicating First Amendment protections.

During the hearing, the company’s attorney, Michael Mongan, described the designation as a distorted use of federal procurement law.

“The logical implication of their position here is they can point to their frustrations in a contract negotiation, the stubbornness of the vendor, and say, ‘because you’re working in an area that touches national security, we’re going to tell the world that we think you might come around in the future and sabotage our systems,’” Mongan said.

The Department of Justice, defending the Pentagon, argued that the designation was a precautionary measure. DOJ attorney Eric Hamilton said the company’s reluctance to allow military use of Claude created an unacceptable operational risk.

“What happens if Anthropic, through an update, installs a kill switch or installs functionality that allows it to change how the software is functioning when our warfighters need it most? That is an unacceptable risk,” he said.

Anthropic has warned that the designation could cost the company billions of dollars in lost contracts and reputational damage. The label is notable as the first public use of this obscure procurement statute against a U.S.-based company. A separate lawsuit in Washington, D.C., challenges another Pentagon supply-chain designation that could exclude Anthropic from civilian government contracts.

Judge Lin said she would issue a written ruling on the request for a temporary block of the designation in the coming days. The case is just one among others, and highlights growing tensions between AI developers seeking to assert ethical boundaries and the military’s insistence on secure, controllable systems, with potential implications for AI companies nationwide.

Anthropic executives maintain that AI models remain insufficiently reliable for deployment in weapons systems and domestic surveillance. Their stance has sparked a wider debate over the ethical and strategic use of AI in national defense, and whether government agencies can wield procurement law to enforce compliance.

The lack of established AI regulation has made the case attractive as it is expected to set a precedent for how AI firms interact with the U.S. military.

German President Frank-Walter Describes Ongoing Middle East Conflict As a Breach of International Law 

0

German President Frank-Walter Steinmeier delivered unusually sharp criticism of the ongoing US-Israeli military campaign against Iran during a speech to German diplomats in Berlin. He described the conflict as a “breach of international law”, a “politically disastrous mistake”, and an “avoidable, unnecessary war” whose stated goal of preventing Iran from acquiring nuclear weapons could have been pursued differently.

Steinmeier specifically challenged the Trump administration’s justification, stating there is “little doubt” that claims of an imminent Iranian attack on the US “do not hold water.” He added: “We have no reason whatsoever to align ourselves with this world view” and argued there is “no reason” for Germany (or Europe) to follow Trump’s lead on this issue.

He equated the damage to transatlantic relations from Trump’s second term to the rupture caused by Russia’s full-scale invasion of Ukraine on February 24, 2022 — saying there would be “no going back” to pre-2025 ties with the US.

He criticized the US withdrawal from the 2015 Iran nuclear deal (JCPOA), in which he had been involved as foreign minister, and argued the war was not the inevitable outcome. He urged Germany to pursue greater strategic autonomy: strengthening its military as the “backbone of conventional defense in Europe” and reducing technological dependence on the US to avoid external interference in domestic affairs.

Steinmeier’s role as president is largely ceremonial, so his comments do not represent official German government policy. Chancellor Friedrich Merz has taken a more cautious line, avoiding direct condemnation of the war’s legality while emphasizing that Iran should not be shielded by international law. German media noted Steinmeier’s remarks as among the strongest public rebukes from a major European figure.

This comes amid reports of a US-Israeli offensive involving strikes on Iranian nuclear and military targets, now in its third week as of late March 2026. The Trump administration has framed the action as necessary to neutralize an existential threat, while critics including some US intelligence voices referenced by Steinmeier question the “imminent threat” narrative.

Iran has vowed not to surrender, and the conflict has driven up oil prices and heightened global tensions. Steinmeier’s intervention highlights deep European unease with unilateral US action under Trump, echoing longstanding transatlantic frictions over Iran policy, defense spending, and alliance reliability. It also fuels debates in Germany about “strategic sovereignty” — reducing over-reliance on Washington.

Whether this rhetorical split translates into concrete policy shifts in NATO, sanctions, or European defense initiatives remains to be seen. For now, it underscores how quickly Trump’s return has strained relations with traditional allies, even as the military campaign continues.

German Chancellor Friedrich Merz (CDU) has adopted a cautious, pragmatic stance on the US-Israeli military campaign against Iran, distinguishing his position from the sharper condemnation by President Frank-Walter Steinmeier. While Merz shares the goal of neutralizing Iran’s nuclear and ballistic missile programs and ending the “terror” of the regime, he has increasingly distanced himself from the execution of the war, emphasizing non-participation and the lack of a viable strategy.

Merz has repeatedly stated that “this is not our war” and Germany will not participate. He stressed that the US and Israel did not consult Berlin beforehand, adding that Germany “would have advised against” the current course of action. The conflict is explicitly “not a matter for NATO.”

Shared objectives but criticism of approach: He agrees with Washington and Jerusalem that Iran must no longer pose a threat and has condemned the Iranian regime harshly. However, he has voiced growing concerns about risks, escalation, and the absence of a “convincing plan” or “joint exit strategy” for ending the conflict swiftly.

“Merz has called for developing a post-war agenda focused on regional stability, preserving Iran’s territorial integrity and state functionality to avoid chaos that could harm Europe, and allowing the Iranian people to determine their future. He warned against an “endless war” or the collapse of the Iranian state.

He has spoken directly with President Trump including raising concerns about potential strikes on Iranian power plants and supports efforts toward a ceasefire, while noting the economic fallout for Germany.

Early in the conflict, Merz was relatively supportive, describing the strikes as aimed at ending Iran’s “destructive game” and avoiding lectures on international law. As the war has dragged into its third week with wider regional effects, his criticism has sharpened: highlighting lack of consultation, risks of escalation, and the need for a clear endgame.

This contrasts with Steinmeier’s March 24 speech, which labeled the war a “breach of international law” and a “politically disastrous mistake” with no reason for Europe to align with Trump’s worldview. Merz has deliberately avoided such legal judgments, focusing instead on practical and strategic concerns.

With oil prices elevated and global tensions high, Merz continues to push for a rapid political resolution while ruling out direct German entanglement. Whether this balance holds as the conflict evolves — particularly around issues like the Strait of Hormuz — will be a key test for his government and EU cohesion.
