L-BTC Trading Reopens on SideSwap With Reserves Covering Only 85%
SideSwap reopened all of its L-BTC markets on Sept. 10 after the Liquid Network resumed block production in a controlled mode, while Liquid Federation peg-ins and peg-outs remained suspended. Readings at 22:55 UTC showed 4,229.33 L-BTC outstanding against 3,601.47 BTC at the cited federation reserve address, implying roughly 85.15% coverage and a shortfall of about 627.85 BTC.

Nasdaq Invests $100M in Kraken Parent Payward for Tokenized Equities Push
Nasdaq will invest $100 million in Payward, the parent company of crypto exchange Kraken, in a deal that values Payward at roughly $21 billion. The partnership is aimed at advancing tokenized equities and always-on, around-the-clock trading markets.

OpenAI claims 10,000-agent model solved Navier-Stokes, reigniting AI safety fears
OpenAI announced on September 8 that an internal model coordinated roughly 10,000 AI agents to solve the Navier-Stokes existence and smoothness problem in 88 hours, a result later formalized in the Lean proof assistant. The claimed proof—that smooth fluid motion can develop a singularity in finite time—remains unverified by independent mathematicians and the Clay Mathematics Institute.

L-BTC Trading Reopens on SideSwap With Reserves Covering Only 85%
This week
SideSwap reopened all of its L-BTC markets on Sept. 10 after the Liquid Network resumed block production in a controlled mode, while Liquid Federation peg-ins and peg-outs remained suspended. Readings at 22:55 UTC showed 4,229.33 L-BTC outstanding against 3,601.47 BTC at the cited federation reserve address, implying roughly 85.15% coverage and a shortfall of about 627.85 BTC.
Why it matters
L-BTC 与 BTC 的 1:1 锚定是 Liquid 侧链的核心价值主张，而 peg-out 暂停后，市场价格已不再能保证按面值赎回，持有者无法确定能收回全部价值。这使个人用户资金、在 Liquid 上发行和结算资产的机构，以及托管 L-BTC 的交易所直接暴露于风险之中，也令联邦制侧链的信任模型受到更严格的审视。

This week
Nasdaq will invest $100 million in Payward, the parent company of crypto exchange Kraken, in a deal that values Payward at roughly $21 billion. The partnership is aimed at advancing tokenized equities and always-on, around-the-clock trading markets.
Why it matters
This is one of the clearest signals yet that a top-tier traditional exchange operator sees tokenization and 24/7 market structure as strategic rather than experimental. It accelerates the convergence of crypto market infrastructure with mainstream equities trading, affecting exchanges, brokers, custodians and tokenization platforms alike.

The claimed proof—that smooth fluid motion can develop a singularity in finite time—remains unverified by independent mathematicians and the Clay Mathematics Institute.
Why it matters
The achievement demonstrates that frontier AI can carry out autonomous, large-scale mathematical research far beyond what public models can do, intensifying debates about economic concentration and the risks of recursive self-improvement. It also underscores the widening gap between private and public AI tools, which could shape the future of AI safety, comp

22-Year-Old Crypto Ringleader Pleads Guilty to $245M Racketeering Scheme
This week
Malone Lam, a 22-year-old ringleader, pleaded guilty to heading an international social engineering scheme that stole approximately $245 million in cryptocurrency. The guilty plea marks a major breakthrough in the high-profile crypto crime case.
Why it matters
This case underscores the growing scale and sophistication of social engineering attacks targeting cryptocurrency holders, and it demonstrates how law enforcement is using racketeering charges to pursue digital-asset criminals. The outcome could heighten scrutiny on security practices and contribute to stricter regulatory and legal precedents across the cryp

Liquid Network hackers steal $320M in Bitcoin, return most after patch
This week
Attackers exploited a vulnerability in Liquid Network's Elements software to mint unbacked L-BTC and drained roughly 4,000 BTC (~$320 million) from its reserve. About 3,400 BTC were returned on Sept. 7, and Blockstream is negotiating to recover the remaining ~600 BTC after patching bridge nodes and preparing an emergency update.
Why it matters
This is one of the largest exploits involving a Bitcoin sidechain and directly tests how much trust users place in federated pegs and wrapped Bitcoin products. It shows that transaction-validation failures can jeopardize user funds even when no private keys or federation nodes are compromised.

Liquid Hackers Return $270M in Bitcoin After $320M Theft
This week
Hackers who breached the Liquid exchange returned about $270 million in Bitcoin after initially stealing roughly $320 million, according to the report. The partial return leaves approximately $50 million in stolen crypto still unaccounted for.
Why it matters
A breach of this size at a cryptocurrency exchange reveals custodial risk and can seriously undermine user confidence in centralized platforms. Partial restitution limits the damage, but the unresolved remainder and the security failure itself may invite stricter regulatory scrutiny and push more users toward self-custody.

Revolut hands passports and Bitcoin data to fake government request
This week
Revolut disclosed that it turned over sensitive customer data — including passport and driver's license copies, verification selfies, IBAN and wallet reference numbers, and full Bitcoin transaction histories — after receiving a fraudulent information request sent from a legitimate government agency's email domain. A Revolut spokesperson called it "a sophisticated external impersonation scam," said a "limited" number of customers were affected, and stated that its systems and customer funds were unaffected, while de
Why it matters
The leak links real-world identities and residential addresses directly to onchain transaction histories, which is exactly the combination that enables physical targeting of crypto holders, and it intensifies scrutiny of how fintechs and exchanges store and release KYC data. Because Revolut is weighing an IPO and recently launched its EURR stablecoin, the in

Blockstream Refuses Ransom After Liquid Bitcoin Exploit
This week
Blockstream publicly refused to pay a ransom for roughly 598.5 BTC (about $47 million) still held by attackers after an exploit on the Liquid Network sidechain that drained around 4,000 BTC, worth roughly $320 million, on Sunday. The attackers returned 3,400 BTC (about 85%) on Monday, and Liquid resumed producing blocks and processing transactions on Thursday with peg-outs still disabled as a precaution.
Why it matters
This is one of the largest confirmed losses on a Bitcoin sidechain, and the reserve backing Liquid's L-BTC fell as low as 197 BTC, raising questions about the security assumptions of federated bridges that many exchanges and traders rely on for fast, confidential Bitcoin transfers. Blockstream's refusal to pay also sets a public precedent for how infrastruct
