According to CryptoQuant analyst Arab Chain, the number of Bitcoin miner deposit transactions has significantly decreased recently, with the current reading at approximately 8,138 transactions, one of the lowest levels in history. This data once exceeded 100,000 transactions by the end of 2025, reflecting a large amount of Bitcoin deposited by miners, which is usually associated with selling intentions or profit-taking. However, since the beginning of 2026, this indicator has shown an overall downward trend, with no clear peak.The current selling pressure from Bitcoin miners has significantly eased, which may provide additional support for the market. The decrease in transaction numbers not only indicates a reduction in deposit amounts but also suggests a lower frequency of transfers to exchanges, reflecting a more conservative behavior among miners.

According to The Block, cryptocurrency mining company MARA's CEO Peter Thiel announced the establishment of a nonprofit organization, the MARA Foundation, dedicated to the long-term health, resilience, and adoption of the Bitcoin protocol. The foundation will support the development of anti-quantum tools (such as PQ wallets and the BIP 360 proposal), believing that while quantum computing is not an immediate threat to Bitcoin, network upgrades take time, and early preparation is crucial.The foundation will also allocate resources to ensure Bitcoin's security budget, support the development of a robust and healthy Bitcoin transaction fee market, and launch a global multilingual education program, expand access to self-custody tools, and engage in advocacy work aimed at policymakers and activists.

The Solana Foundation stated that its core development team Anza has reached an agreement with Firedancer, a subsidiary of Jump Crypto, on a potential post-quantum solution, planning to introduce a new digital signature scheme called Falcon.Although the threat of quantum computing is not expected to materialize for several years, Solana has developed a phased upgrade roadmap. This plan includes ongoing research into Falcon and other alternatives, introducing post-quantum solutions for new wallets when necessary, and ultimately completing the migration of existing wallets. Currently, the quantum-resistant primitive Winternitz Vault, developed by Blueshift, has been running on Solana for over two years. The Solana Foundation stated that the network's high-speed, low-latency design can accommodate such solutions, and the migration is not expected to have a significant impact on performance.

Solana's official article on the potential impact of quantum computing on blockchain reiterates that the quantum threat is still years away, but the Solana ecosystem has already conducted thorough research and technical preparations in advance.The independent verification client development teams Anza and Firedancer (which together represent a large portion of the network's staking share) have unanimously concluded after independent research that a compact signature scheme suitable for high-throughput blockchains is needed, and they have jointly selected the Falcon scheme. Both parties have published their initial implementation code on GitHub.In addition, the Solana Winternitz Vault developed by Blueshift has been operational in the ecosystem for over two years, providing a direct quantum-resistant path. Earlier this year, Google Quantum AI listed this Vault as a leading example of forward-looking post-quantum work in its white paper.Solana's current quantum roadmap includes ongoing quantum research and evaluation of Falcon and alternative solutions; adopting post-quantum solutions for new wallets when quantum becomes a credible threat; and migrating existing wallets to the selected solution. The official statement indicates that the migration work is manageable and can be completed quickly when the time comes, with network performance expected to remain largely unaffected.

CryptoQuant analyst Darkfost posted on the X platform that Binance attracted a total of $6 billion in stablecoin inflows in March and April, with nearly $3.5 billion in net inflows in April, contrasting sharply with the previous net outflow of about $7.6 billion.Despite the escalating tensions between the U.S. and Iran increasing market uncertainty and concerns about rising inflation being unfavorable for risk assets, the trend of stablecoin inflows has clearly shifted. The analyst pointed out that when inflows to major exchanges exceed outflows, it indicates that some parts of the market are beginning to reposition themselves to participate in the gradual recovery over the past two months. If this trend continues, it may provide support for a short-term positive market.

CryptoQuant CEO Ki Young Ju stated that the recent rise in Bitcoin is mainly driven by the futures market, while on-chain spot demand remains negative.He pointed out that, based on historical experience, bear markets typically require a synchronized recovery of both spot and futures demand to potentially end.

CryptoQuant analyst Axel Adler stated that after the release of market pressure in the spring, the selling pressure from short-term holders (STH) has significantly eased. The Bitcoin market repair is still ongoing, and the current price is close to the cost line of short-term holders. The key trigger for the subsequent trend lies in whether it can effectively stabilize above the short-term holder cost basis of about $83,000. Only by breaking through and stabilizing above this level can the market further validate the actual selling pressure strength of short-term holders and whether it will suppress the price drop again.

According to CoinDesk, while quantum computers cannot disrupt the Bitcoin mining mechanism or the blockchain ledger, they may potentially crack the elliptic curve encryption system that protects wallet ownership through Shor's algorithm. Currently, about 6.9 million BTC (approximately one-third of the total supply) face potential risks due to public keys being visible on-chain, including around 1 million early holdings by Satoshi Nakamoto; transactions generated after the Taproot upgrade in 2021 are also affected due to public key exposure.Ethereum has established a formal quantum resistance migration plan since 2018, with 4 full-time teams and over 10 independent development groups, and has launched a dedicated progress website at pq.ethereum.org. In contrast, Bitcoin currently lacks a unified response roadmap, and the existing BIP-360 proposal and BitMEX Research detection scheme have not received widespread support from core developers. Notable Bitcoin advocate Nic Carter pointed out that Bitcoin's response is "the worst," while Blockstream CEO Adam Back believes that current quantum systems are still in the laboratory stage, but he also agrees that optional upgrade solutions should be deployed in advance.Analysts point out that Bitcoin's anti-centralization governance culture makes coordinating large-scale security upgrades extremely difficult, and how to handle historical legacy issues such as Satoshi Nakamoto's holdings is particularly challenging. A related paper from Google warns that once quantum attacks become a reality, the window for response may have already closed.

Project Eleven today awarded the Q-Day prize to researcher Giancarlo Lelli, who successfully derived a 15-digit elliptic curve private key from a public key using publicly accessible quantum hardware, marking the largest scale demonstration of its kind to date, a 512-fold increase from the 6-digit demonstration in September 2025.Lelli used a variant of Shor's algorithm for the elliptic curve discrete logarithm problem, which is the mathematical foundation of the Bitcoin signature scheme, with the awarded hardware featuring approximately 70 qubits. Currently, no known quantum computer can crack real Bitcoin wallets, and the security of Bitcoin's 256-bit elliptic curve remains far beyond current quantum capabilities. Notably, Google lowered its resource estimates for ECDLP-256 on March 31 and set a target for the migration to quantum cryptography after 2029, followed by Cloudflare, and the UK's NCSC also set migration milestones from 2028 to 2035.On-chain data shows that approximately 6.93 million BTC are at potential quantum risk due to exposed public keys. The Bitcoin community has proposed BIP 360 and BIP 361 to promote the migration to quantum-resistant output types, but the coordination challenges of a decentralized network remain the biggest hurdle.

CryptoQuant analyst MorenoDV_ tweeted that if Bitcoin can rise above and hold the $80,000 mark, this position will turn from resistance to support; conversely, if it encounters rejection and falls back, it will confirm $80,000 as a significant selling pressure area, potentially extending the adjustment period into the second quarter.Currently, the realized price for BTC ETF investors is about $76,400, which is close to the spot price (around $76,300), marking the first time since January 30 that it has approached the breakeven point; short-term holder whales have a realized price around $79,600 and are currently facing an unrealized loss of about $9.4 billion.MorenoDV_ pointed out that historically, when these trapped funds are finally released, it often triggers significant selling pressure. Bitcoin is currently fluctuating in the $76,000-$80,000 range, where $80,000 is not only an important psychological level but also a common breakeven and release threshold for these two major groups.

Former Jump Trading senior quantitative researcher Yiming Zhang has received startup funding support from hedge fund giant Millennium Management after leaving the firm and will conduct business as an external manager in the future.Yiming Zhang worked at Jump for 17 years and was one of the key members of the core strategy department. Due to non-compete clauses, his new role is expected to officially start after the restriction period ends. Industry insiders point out that Millennium Management has been expanding its footprint in recent years by providing funding support to external teams, becoming one of the important "incubators" in the hedge fund sector.

According to on-chain analysis platform Nansen, in the past 24 hours, whale and celebrity wallets have continued to accumulate HYPE, while exchange supply has decreased by 22.86% during the same period. Specifically, the high-balance address [Adeub6BN] made five consecutive purchases in one afternoon, with each transaction amounting to between $51,000 and $99,000; the address lajay.sol made another purchase of about $66,000 eight hours ago; Token Millionaire [GJvewfRj] directly withdrew HYPE from the Meteora liquidity pool.

The "Quantum Computing and Blockchain Independent Advisory Committee" established by Coinbase has released its first position paper. The core conclusion of this position paper is that the core infrastructure of Bitcoin is fundamentally secure. Quantum computing does not pose a substantial threat to Bitcoin mining, hash functions, and the historical records of the blockchain. The real vulnerability lies at the wallet level, and Ethereum has laid out a clear roadmap to address this issue in the near future.Previously, Coinbase announced the establishment of the Quantum Computing and Blockchain Independent Advisory Committee in January this year, with committee members including researchers from Stanford University, the University of Texas at Austin, and the Ethereum Foundation.

According to Decrypt, Coinbase's Quantum Computing and Blockchain Independent Advisory Committee released a report on Tuesday stating that proof-of-stake (PoS) blockchains may face a greater risk of exposure to future quantum computing attacks, as the cryptography relied upon by the validator signatures that protect these networks could ultimately be cracked by sufficiently powerful quantum computers. The report points out that PoS networks like Ethereum and Solana rely on cryptographic signatures—Ethereum validators use BLS signatures, while Solana validators and users use Ed25519 signatures—to help the network reach consensus on blocks and maintain consensus.The advisory committee stated, "PoS chains have exposure risks in the signature schemes used by validators to protect the network, which means that the challenges faced by PoS are not just about upgrading wallets; parts of the core consensus mechanism itself may need to be redesigned." The report mentioned recent work by Ethereum developers, including a proposal by co-founder Vitalik Buterin in February to replace BLS validator signatures, KZG commitments, and ECDSA wallet signatures with quantum-resistant alternatives.The committee also listed the digital signatures used in cryptocurrency wallets as another major long-term vulnerability, estimating that about 6.9 million bitcoins belong to the category where the public keys are already visible on-chain. The report stated that the current cryptocurrency system remains secure, as quantum computers capable of breaking modern cryptographic signatures do not yet exist.

The Coinbase Quantum Computing and Blockchain Independent Advisory Committee has released its first position paper stating that sufficiently powerful quantum computers may be able to crack the encryption mechanisms used by mainstream blockchains to protect digital assets in the future. However, such devices do not currently exist, and encrypted assets remain secure for now. The industry should begin preparing for quantum resistance upgrades starting now.The document points out that there are currently no substantial risks associated with Bitcoin mining, hash functions, and on-chain historical records; the main vulnerability lies in the digital signatures at the wallet layer. Ethereum has proposed a clearer migration roadmap, and Solana, Algorand, and Aptos have also begun to provide or plan quantum resistance solutions.

ChainCatcher reported live that Justin Sun, the founder of TRON, shared a keynote speech titled "From TRON to B.AI: Infrastructure as the Game-Changer in the AI Era" at this year's 2026 Hong Kong Web3 Carnival.He introduced that TRON currently supports about 86.4 billion USDT, with other stablecoins bringing the total close to 90 billion dollars, and the global account number has reached 376 million, making it one of the largest stablecoin settlement networks in the world. He emphasized that the most important aspects of financial services are stability and security, rather than being cheap.He pointed out that the existing payment systems are not compatible with AI, as bank accounts require human identity for opening, and each payment needs manual authorization, which cannot support high-frequency decision-making by AI. B.AI is building the underlying financial infrastructure for AI agents, allowing each AI to operate without becoming human, managing keys and on-chain wallets through cryptography to complete payments, and can anonymously call the world's most

Ripple officially announced its quantum resistance roadmap, with the core goal of making the XRP Ledger (XRPL) quantum-resistant by 2028. The roadmap primarily addresses the potential attack mode of "harvest now, decrypt later," where attackers collect encrypted data now and wait for future quantum computers to mature before cracking it.The entire plan will be implemented in four phases:Phase 1: Q-Day Emergency Preparedness (Already Started). Establish a Q-Day emergency response mechanism. If the existing classical encryption system is suddenly compromised, the network will immediately stop accepting traditional public key signatures, forcing a migration to quantum-safe accounts. At the same time, explore asset ownership verification solutions based on Post-Quantum ZK-proofs, allowing existing account holders to safely recover funds in emergencies without exposing vulnerable keys.Phase 2: Risk Assessment and Algorithm Testing (First Half of 2026). Conduct a comprehensive assessment of the impact of post-quantum cryptography on the performance, storage, and bandwidth of the XRP Ledger network. Collaborate with Project Eleven to conduct validator-level testing and Devnet benchmarking, deploy NIST standardized ML-DSA quantum-safe signature schemes, and develop prototypes for post-quantum custodial wallets. Core engineer Denis Angell has already deployed ML-DSA signatures on XRPL's AlphaNet.Phase 3: Devnet Hybrid Integration (Second Half of 2026). Parallel integration of candidate post-quantum signature schemes with existing elliptic curve signatures on the developer network (Devnet), allowing developers to test performance and system impacts without affecting the mainnet. At the same time, explore post-quantum zero-knowledge proof primitives and homomorphic encryption technologies for Confidential Transfers to enhance the privacy and compliance capabilities of tokenized real-world assets on XRPL.Phase 4: Full Mainnet Upgrade (Target 2028). Submit a formal protocol amendment, which will be fully enabled on the mainnet after being approved by validator votes, to implement native post-quantum cryptography. Focus on production-ready optimization: throughput tuning, validator reliability assurance, and coordinated migration of the ecosystem, ensuring a complete transition without affecting network speed and settlement finality.

Sonic elaborates on its technological path towards the "post-quantum era," pointing out that most current PoS public chains rely on elliptic curve signatures (such as ECDSA, Ed25519), which are at risk of being cracked once quantum computing (like Shor's algorithm) matures.Sonic states that the industry is exploring post-quantum cryptographic solutions (such as hash-based XMSS, SPHINCS+, and lattice-based Dilithium, Falcon), but mainstream consensus mechanisms generally rely on BLS aggregate signatures and threshold signatures, making the transition to post-quantum systems face challenges in performance, bandwidth, and architectural reconstruction. In contrast, Sonic's SonicCS consensus protocol does not rely on aggregate signatures or global randomness, but instead uses single-node signatures and hash functions to construct a DAG structure. Therefore, when switching to post-quantum cryptography, only the signature algorithm needs to be replaced to complete the upgrade, without the need to adjust the consensus logic or network structure. Sonic emphasizes that this design will significantly reduce the complexity of future migrations to post-quantum security, enabling the network to have stronger adaptability when quantum computing threats arise.
