According to The Bitcoin Historian, billionaire Jack Dorsey's cryptocurrency financial application platform Cash App officially launched its Bitcoin reserve proof feature this week, verifying that over 60 million users' Bitcoin holdings on its platform are fully backed 1:1.The market views this move as an important step for the cryptocurrency industry in terms of transparency, user trust, and self-custody standards, and it is also seen as a positive signal for promoting the long-term healthy development of the industry.

According to Cointelegraph, Aptos recently launched the privacy token Confidential APT on its mainnet, which is pegged to APT at a 1:1 ratio. It uses zero-knowledge proofs to hide token balances and transfer amounts while maintaining wallet address visibility and transaction verifiability.Sherry Xiao, founding engineer of Aptos Labs, stated that the token aims to address the long-standing contradiction between blockchain privacy and compliance transparency, and can solve issues related to the public exposure of sensitive information such as on-chain salaries, treasury operations, and trading strategies. On the compliance front, the activation of the audit key must be approved through on-chain governance voting. The launch of Confidential APT stemmed from a governance proposal that was nearly unanimously passed. Xiao expects individual user adoption to be faster than that of enterprises, and if the mainnet operates stably for six months with good transaction volume, it will help shorten the sales cycle for enterprises.

According to official news, Block has released a proof of reserves, stating that by the end of the first quarter of 2026, the company holds a total of 28,355.05 bitcoins, valued at approximately 2.2 billion dollars. Among them, customer holdings are 19,357.16 bitcoins (approximately 1.5 billion dollars), and the company's treasury holds 8,997.89 bitcoins (approximately 696 million dollars).

The blockchain interoperability protocol Hyperbridge disclosed details of the previous DOT attack incident, resulting in a loss of approximately $237,000. The root of the vulnerability lies in the HandlerV1 contract's VerifyProof() function, which lacks input validation and does not verify the leaf_index leafCount, allowing attackers to forge Merkle proofs.Using this, the attacker gained administrator privileges for the DOT token bridging contract on Ethereum, subsequently minting 1 billion bridged DOT (which is about 2800 times the legitimate circulation of approximately 356,000) and cashing out on decentralized exchanges. Hyperbridge stated that it is currently working with security partners to trace the funds, and cross-chain functionality will remain suspended until the investigation is completed.

According to monitoring by BlockSec, the HandlerV1 contract managed by Hyperbridge has a Merkle Mountain Range (MMR) proof replay vulnerability on the Ethereum network, resulting in a loss of approximately $242,000. The vulnerability arises from the proof not being bound to the request, allowing attackers to replay historically valid proofs and combine them with new forged requests to perform actions such as changing administrator permissions.In a specific case, the attacker changed the administrator of the Polkadot (DOT) Token and then exploited the permissions to mint additional DOT for profit. Related attack transactions have been observed, including changing the administrator and minting of DOT Token (loss of approximately $237,400), changing the administrator and minting of ARGN Token (loss of approximately $3,800), and host withdrawals, among others.Previously, it was reported that the Hyperbridge gateway contract was attacked, resulting in the minting and dumping of 1 billion DOT on Ethereum.

In response to Binance founder Zhao Changpeng (CZ) proposing a bet of $1 billion (or any amount) regarding the claim of "already officially divorced," OKX Star stated that as the CEO of OKX, he cannot participate in such public bets due to the company's compliance culture, and gambling is also illegal for UAE citizens.He emphasized that to verify whether CZ is officially divorced, it is sufficient to show whether Binance's shares have been legally divided from his ex-wife, without the need for a betting proof. Furthermore, the division of marital property after a 20-year marriage is not only a legal obligation but also a basic moral responsibility. He has no interest in CZ's private life but reserves the right to question and clarify any false statements about himself made in the book and public interviews.Previously, CZ demanded an apology from Star and stated that if the bet is not accepted within 24 hours, it would prove who is misleading the public.

Cysic officially announced the open-source Graph-First zkVM proof framework Venus. Venus is built on top of ZisK, abandoning the traditional HAL model that treats the proof process as a series of isolated backend functions, and encoding the entire ZK proof process into a global computation graph, decoupling logic from hardware execution.Tests show that Venus improves end-to-end proof time by over 9% compared to the existing ZisK 0.16.1, significantly reduces CPU-GPU synchronization overhead, and is compatible with GPU, FPGA, and even ASIC.Cysic has been listed as an integration partner of Ethproofs and will directly operate as an Ethereum zkEVM node. The ZisK zkVM that Venus is based on uses a custom instruction set and is one of the five major zkVMs explicitly listed as candidates in the official discussion of the Ethereum EIP-8025 upgrade, allowing Cysic to directly enter the core track of the Ethereum L1 proof market.

The decentralized zero-knowledge proof verification layer Aligned updates the ALIGN token economics, with a total supply of 10 billion tokens and an initial circulation of approximately 16%.Of this, 23.5% will be allocated to the team (40% cliff unlock after 12 months, with the remaining portion unlocking linearly over 18 months), 19.71% will be allocated to investors, 18% will be allocated for the ecosystem (3.23% unlock at TGE, 6 months cliff unlock, with the remaining portion unlocking linearly over 24 months), 16.61% will be used for future reserves (40.24% unlock at TGE, 6 months cliff unlock, with the remaining portion unlocking linearly over 24 months), 11.4% will be allocated to the foundation (37.83% unlock at TGE, with the remaining portion unlocking linearly over 30 months), 8.74% will be used for airdrops (44.36% unlock at TGE), and 2.04% will be used for community sales (32.72% unlock at TGE).

Citi, PwC, and Solana have jointly completed a proof of concept (PoC) for trade finance tokenization—suppliers can issue tokenized payment vouchers to be sold to banks at a discount for instant settlement instead of waiting for months.Traditional financial giants have sent another signal to explore RWA (real-world assets) on the Solana chain.

Binance announced the 40th proof of asset reserves, with a snapshot date of March 1. User assets continue to maintain a reserve ratio of at least 1:1. The BTC assets are approximately 631,000 coins, a decrease of 8,004 BTC from February 1; the ETH assets are approximately 3.87 million coins, a decrease of 307,203 ETH from the last report; the USDT assets are approximately 36.4 billion coins, a decrease of about 360 million USDT from the last report.

Mitsubishi UFJ, with an asset size of $30 trillion in Japan, announced that it will use AI for loan reviews and conduct a joint stablecoin proof of concept with three major banks.

According to The Block, a16z Crypto criticized the colloquial use of the term "ZK" in certain developer environments in a blog post about its Jolt zkVM. The article pointed out that most zkVMs do not actually possess zero-knowledge properties unless expensive "wrapping" programs are applied. The author also mentioned that "zk" often becomes synonymous with "conciseness," meaning "short proofs that verify quickly," rather than true zero-knowledge privacy.As the community's focus on privacy grows, the misuse of this terminology is becoming a real issue. a16z's open-source Jolt zkVM launched a major upgrade on Tuesday, natively supporting zero-knowledge proofs. Jolt employs the NovaBlindFold folding scheme to create blinded proofs to prevent information leakage, making it suitable for privacy applications, with the zero-knowledge proofs generated after the upgrade only increasing by about 3 KB compared to the original non-ZK proofs.

SlovakBitcoin developer and RustBitcoin library maintainer Martin Habovštiak has released a proof of concept that writes a 66 kB TIFF image file to the Bitcoin blockchain through a single transaction without using OP_RETURN, Taproot, or OP_IF. The transaction can be publicly verified on-chain and can be decoded into a complete image file.This experiment is seen as a direct challenge to the "anti-spam" soft fork proposal BIP-110, promoted by Luke Dashjr. BIP-110 is a successor to BIP-444, which aims to limit the scale of on-chain data writing, with some supporters arguing that such data storage practices deviate from Bitcoin's core positioning as a "currency."

At the "Build and Scale in 2026" themed forum held by ChainCatcher in Hong Kong, Michael, co-founder & CEO of the ZK verifiable computing platform Brevis, delivered a keynote speech on "The Infinite Computing Layer Where Everything Can Be Computed," sharing how ZK technology is driving a fundamental transformation in the blockchain computing paradigm.Michael pointed out that the current on-chain computing costs are high and the speed is slow. The "verifiable computing" paradigm proposed by Brevis can offload heavy computations to off-chain, requiring only low-cost verification on-chain, achieving decoupling of computation and verification while supporting privacy protection scenarios.The speech showcased the performance breakthroughs of Brevis's core product, Pico ZKVM: its latest generation, Pico Prism, can complete Ethereum block proofs in an average of 6.9 seconds, with 99.6% of blocks completed within 12 seconds, achieving real-time proof (RTP) for Ethereum for the first time. Currently, Pico ZKVM, as an "on-chain ZK data co-processor," has been applied in various scenarios such as privacy-preserving incentive distribution, high-performance DeFi, and trustless on-chain data computation, providing Rust programming support for developers with zero ZK development experience.Michael predicts that in the next 10 years, 99% of blockchain computing will occur off-chain, verified through ZK proofs. Brevis is driving this process through its verifiable computing infrastructure.

According to The Block, CFTC Chairman Michael Selig stated in a Washington Post article that the Commodity Futures Trading Commission is charting a new course and has announced the launch of a new initiative called Future Proof, aimed at modernizing the regulatory approach to digital assets.Michael Selig mentioned that the derivatives regulatory body needs an upgrade and plans to conduct a comprehensive review of existing rules, with the goal of adopting what he describes as a minimum effective dose of regulation. He pointed out that decades-old rules designed for agricultural futures contracts are not suitable for emerging products or trading venues, and just as American businesses modernize the traditional financial system by leveraging new technologies, the CFTC must upgrade its approach to unleash innovation.Michael Selig, appointed by Donald Trump, took office last month and stated that if Congress passes legislation on the market structure for digital assets, the CFTC will take on a broad new set of responsibilities and ensure that these markets thrive domestically through a tailored regulatory framework, maintaining the leading position of the U.S. market. Currently, lawmakers are debating a bill to expand the CFTC's jurisdiction over the digital asset industry.

According to CoinDesk, Hsiao-Wei Wang, co-executive director of the Ethereum Foundation, stated in an interview with CoinDesk that Ethereum is steadily moving towards making zero-knowledge cryptography a core component of the network in the future. Hsiao-Wei Wang described zero-knowledge as part of Ethereum's mid-term roadmap and noted that several breakthroughs have been achieved in the past year or two.While the current upgrade focus remains on improving Layer 2 network execution and Blob space, zero-knowledge as a protocol-level feature has become increasingly feasible. Ethereum researchers have released a native zkEVM plan that allows the network to use zero-knowledge proofs to validate transactions by default. This technology can significantly reduce the workload required to secure Ethereum, achieving scalability without sacrificing decentralization or reliability. Hsiao-Wei Wang emphasized that even as the network continues to evolve, resilience, security, censorship resistance, and neutrality remain core to Ethereum.

The Ethereum L2 network Starknet released an analysis report on the short-term mainnet outage that occurred this Monday, stating that the cause of the incident was the inconsistency between the execution layer (blockifier) and the proof layer: under specific cross-function calls and rollback combinations, the execution layer incorrectly recorded a state write that had been rolled back, leading to abnormal transaction execution. The related transactions did not receive L1 finality confirmation. This incident triggered a block reorganization, with approximately 18 minutes of on-chain activity being rolled back.This is the second major interruption since 2025, following a September incident where a sequencer vulnerability caused an outage of over 5 hours and rolled back about 1 hour of on-chain activity.
