Aave announced that its bug bounty program has been updated to better align rewards with the risk status of each part of the ecosystem and to simplify the review process. The maximum reward for critical vulnerability fixes for Aave V4 and Core Aave V3 has now been increased fivefold.

According to informed sources, Payward, the parent company of the cryptocurrency platform Kraken, is conducting a new round of capital financing at a valuation of $20 billion, to which Kraken declined to comment.The company has recently significantly increased its merger and acquisition spending—acquiring the stablecoin-focused payment company Reap for $600 million and the digital asset derivatives platform Bitnomial for $550 million, both transactions conducted at a $20 billion valuation.Its largest transaction was the $1.5 billion acquisition of the U.S. retail futures platform and CFTC-registered futures commission merchant NinjaTrader in 2025, which provided Kraken with a significant foothold in the U.S. derivatives market.Regarding IPO progress, Payward secretly submitted an S-1 registration statement draft to the U.S. SEC on November 19, 2025. Although reports in March 2026 indicated that the company paused its IPO plans due to unfavorable market conditions, sources stated that the company still intends to go public, but may wait for market improvements.At last week's Consensus conference in Miami, Payward co-CEO Arjun Sethi stated that the trading platform is "80% ready" for an IPO.Additionally, Deutsche Börse (DB1) purchased approximately 1.5% of Payward's shares for $200 million through a secondary share sale in April 2026, valuing Payward at $13.3 billion (lower than the previous financing round's valuation of about $20 billion).In November 2025, Kraken completed an $800 million financing in two tranches to push traditional financial products onto the blockchain, with investors including Jane Street, DRW Venture Capital, and Tribe Capital. Subsequently, Citadel Securities also made a strategic investment of $200 million at a $20 billion valuation.

According to Lookonchain monitoring, four wallets possibly associated with Paradigm Capital deposited 11,615 ETH (27.29 million USD) into FalconX three hours ago.

According to Cointelegraph, Colombian President Gustavo Petro has publicly stated that Colombia should follow the example of Venezuela and Paraguay by actively attracting Bitcoin mining investments, and pointed out that the undeveloped renewable energy along the Caribbean coast is a core advantage for promoting mining development.

According to Onchain Lens monitoring, Paradigm Capital deposited 2,436 ETH, worth 5.75 million dollars, into Coinbase Prime in the past 2 hours.

Kraken co-CEO Arjun Sethi stated at the Consensus Miami conference that the preparations for KrakenIPO are about 80% complete, and the company has submitted an application to the U.S. Securities and Exchange Commission, currently waiting for the right market window.Kraken also announced a partnership with MoneyGram, where both parties will collaborate on scenarios involving the exchange of crypto assets and cash to address the "last mile" cash access issue. MoneyGram currently has approximately 500,000 retail locations worldwide. Executives from both sides stated that stablecoins are expected to reduce costs and efficiency losses in payment systems, especially in regions with weaker financial infrastructure.

Concerns about quantum computing in Bitcoin always revolve around a "Satoshi-related problem." If a sufficiently powerful quantum computer emerges, millions of Bitcoins stored in old wallets with exposed public keys may face the risk of being stolen, including approximately 1.1 million Bitcoins that are allegedly owned by the anonymous creator Satoshi, currently valued at about $84 billion.Senior developer Jameson Lopp and five other developers formally proposed this plan through BIP-361 in mid-April, which aims to gradually phase out addresses vulnerable to quantum attacks over a five-year timeline and freeze any coins that fail to complete the migration. However, this proposal creates another issue: Satoshi and all other long-dormant holders would have to publicly "reveal themselves," or risk losing access to their assets.Dan Robinson, a general partner at Paradigm, released a proposal on Friday that suggests a way to circumvent this trade-off, with the core concept being "Provable Address Control Time Stamps" (PACTs). The main idea of PACTs is not to move coins, but to timestamp ownership proofs on specific dates, without disclosing any information externally until the wallet owner truly needs to spend.If Bitcoin later implements a soft fork to freeze coins vulnerable to quantum attacks, the protocol could include a rescue path that accepts STARK proofs (a type of zero-knowledge proof that remains secure against quantum computers), proving that the holder created their commitment before the existence of quantum hardware. When the holder wishes to spend, they submit this proof, and the network releases the corresponding coins. This redemption process will not reveal any information about the address, amount, or even the original timestamp creation time.

Paradigm general partner Dan Robinson proposed the "Proof of Address Control Timestamp" (PACTs) mechanism, aimed at providing a protection path for Bitcoin addresses against potential threats from quantum computing.This solution allows holders to generate address control proofs through BIP-322 and create on-chain commitments using a random salt value, completing time anchoring with OpenTimestamps to establish ownership proof without disclosing wallet information. If quantum-vulnerable addresses are frozen in the future through a soft fork, users can submit STARK zero-knowledge proofs to unlock their assets when spending. This mechanism also provides a potential recovery path for wallets derived from BIP-32, but its implementation still relies on Bitcoin introducing STARK verification capabilities and gaining community consensus.

Researcher Dan Robinson from Paradigm proposed a new scheme called PACT (Verifiable Address Controlled Timestamp), aimed at protecting long-dormant bitcoins, including Satoshi's early addresses, from future quantum computing attacks.This mechanism allows users to prove their control over an address through a timestamp without the need to transfer assets or expose on-chain behavior. Once future quantum attacks occur, assets can be recovered in a quantum-resistant version of the Bitcoin network based on that proof. Compared to mandatory migration schemes (like BIP-361), PACT avoids the privacy exposure issues caused by actively transferring assets, providing long-term holders with a more flexible preemptive protection path.

According to MLM monitoring, Paradigm has transferred all 2.14 million HYPE to the Coinbase Prime address in the past two days, with a total value of approximately 86 million dollars based on current prices. This large transfer has attracted market attention, as institutional funds moving to Coinbase Prime may be related to custody, market making, over-the-counter trading, or potential sale arrangements, but the specific use has not yet been disclosed.

Nic Carter, a partner at Castle Island Ventures, published a lengthy article on the X platform pointing out that the quantum computing "canary warning" mechanism cannot provide sufficient buffer time for BTC. Classical computers can currently crack approximately 117 to 130 bits of the Elliptic Curve Discrete Logarithm Problem (ECDLP), and results below this threshold are often questioned for "classical cheating" or pre-set answers, thus failing to form an effective signal.Nic Carter believes that once quantum computers truly break this classical limit, the time left for a direct attack on the 256-bit secp256k1 curve used by Bitcoin may only be a matter of months, while the migration to post-quantum (PQ) signatures after Bitcoin's completion could take years. Whether setting up quantum cracking bounty addresses or relying on Satoshi's early dormant addresses as on-chain warnings cannot guarantee sufficient early detection of risks. Therefore, the truly feasible approach is not to wait for clear warnings but to immediately begin preparations for post-quantum migration. Previously, BitMEX Research proposed a quantum freeze alternative: the "canary address" trigger mechanism.

According to CNBC, the crypto data and research platform Blockworks announced the completion of its Series A extension financing, with a post-money valuation of $192 million. This round was co-led by Parafi Capital and Reciprocal Ventures, with participation from several institutions including Coinbase Ventures, Advancit Capital, and MoonPay. Over 20 founders and operators from projects such as Solana, LayerZero, Pyth, EigenLayer, Kraken, Arbitrum, and Polygon also participated personally, though the specific financing amount has not been disclosed.The company stated that the crypto market has grown to a trillion-dollar scale without the infrastructure of traditional capital markets, but still faces issues such as data fragmentation, inconsistent disclosures, and a lack of communication mechanisms for investors. Blockworks aims to fill this gap through a "data + disclosure + investor relations" integrated framework.

According to The Wall Street Journal, Parallel Web Systems, an AI infrastructure company founded by former Twitter CEO Parag Agrawal, has completed a $100 million Series B financing round, with a post-money valuation of $2 billion.This round was led by Sequoia Capital, with participation from existing investors such as Kleiner Perkins, Index Ventures, and Khosla Ventures. Parallel provides efficient web search and access control infrastructure for "long-cycle" AI agents, having raised a total of $230 million, with around 50 employees, serving over 100,000 developers and enterprise clients. The current focus is on expanding the sales, marketing, and R&D teams, continuously laying out the enterprise-level "AI agent web" scenario.

The Korean National Tax Service has initiated preparations for the taxation of virtual assets, aiming for formal implementation in January 2027, and is preparing for comprehensive income tax declarations in May 2028.According to the current income tax law, income from the transfer and leasing of virtual assets will be classified as "other income," with a tax rate of 22% applied to the portion of annual income exceeding 2.5 million won, affecting approximately 13.26 million people. The Korean National Tax Service plans to obtain data from exchanges such as Upbit, Bithumb, Coinone, Korbit, and Gopax starting next year to improve the tax collection infrastructure and promote the launch of a comprehensive analysis system for virtual assets within the year. However, controversies surrounding the taxation standards and the risk of capital outflow continue.

Supported by Paradigm, Succinct Labs has released the iPhone camera app ZCAM, which generates "digital fingerprints" for photos and videos using cryptographic technology to address the forgery risks posed by AI-generated content.ZCAM can sign images at the moment of capture, creating an immutable record and binding the content to the capturing device, allowing users to independently verify whether the material comes from a real device, whether it has been tampered with, or whether it was generated by AI. Unlike solutions that rely on AI detection, Succinct chooses to start from the hardware layer of the device, generating a unique cryptographic signature for each shot. The company states that existing AI detection tools are prone to failure, while this solution can enhance the reliability of authenticity verification. Similar projects include World, which aims to reduce risks by distinguishing between real human and AI identities.
