Bitmine officially launches institutional-grade Ethereum staking platform MAVAN

Bitmine, a Nasdaq-listed Ethereum treasury company, announced the official launch of MAVAN (Made in America Validator Network), an institutional-level Ethereum staking platform, aiming to provide institutions with high-security, high-performance and high-resilience staking infrastructure. MAVAN combines local verification nodes in the United States with a global distributed architecture, which not only meets the needs of institutions with local compliance infrastructure requirements, but also supports global customer access. The platform was initially used to support Bitmine's own Ethereum asset allocation and will be open to institutional investors, custodians and ecological partners in the future. As of March 24, 2026, Bitmine has pledged approximately 3.1426 million ETH (approximately US$6.8 billion).

Ethereum Foundation launches post-quantum security resource platform

On March 24, the Ethereum Foundation announced the launch of a post-quantum security resource platform to showcase Ethereum’s research progress and roadmap in the direction of post-quantum security. The project is led by the post-quantum team and the cryptography team, and is jointly promoted by the protocol architecture and coordination team. Related research has continued for more than 8 years. The platform covers the impact of post-quantum on various protocol layers, complete roadmap, open source code and specifications, etc. Currently, more than 10 client teams have participated in relevant development network testing.

The European Central Bank paper questions the degree of decentralization of DeFi governance tokens

On March 27, the European Central Bank staff paper pointed out that DeFi protocol governance tokens are highly centralized, and about half or more of the governance token holdings of Aave, MakerDAO, Ampleforth, and Uniswap are related to the protocol itself or the exchange. The main voting participants are mostly delegates, and in many cases these representatives cannot be identified or associated with token holders. The study questions whether DeFiDAO is decentralized enough to be excluded from the MiCA regulatory framework and provides a regulatory reference for policymakers.

ARK Invest introduces Kalshi prediction market data: used for investment decisions and risk hedging

On March 27, ARK Invest, an investment institution owned by Cathie Wood, announced that it will use data from the prediction market platform Kalshi to guide investment decisions and hedge risks. ARK said it will use Kalshi in three ways: first, to provide "continuously updated expectations" supplements for fundamental and quantitative analysis; second, to obtain real-time market expectations through indicators such as trading volume; third, for event-driven risk management, including hedging specific results affecting the investment portfolio as well as macro and industry risks. Cathie Wood pointed out that introducing prediction markets into the institutional investment process is a natural extension of financial research innovation and can help quantify uncertainty and improve the quality of decision-making. Nick Grous, ARK Research Director, said that the prediction market can more purely reflect the risk expectations of key economic and corporate events.

Coinbase joins forces with Better to launch crypto mortgage mortgage, supporting BTC and USDC for mortgage purposes

Coinbase announced that it has cooperated with Better, an American online mortgage platform, to launch the first compliant crypto mortgage mortgage product, which allows users to use the Bitcoin or USDC in their Coinbase accounts as collateral to pay for the down payment of a home. The relevant mortgages are issued and managed by Better and have the same legal protection as traditional compliant mortgages. It is reported that the product structure is a "dual loan model": one is a standard mortgage loan, and the other is a down payment loan mortgaged with crypto assets. The interest rates and terms of the two are the same. Users only need to bear a combined monthly payment. The mortgage assets will be hosted in the Coinbase Prime account and will be returned after the loan is repaid, and the mortgage terms are not affected by BTC price fluctuations.

CastleIsland Ventures: Elliptic curve cryptography is about to be eliminated, and developers should realize as soon as possible that cryptographic algorithm variability should be built into the network

On March 26, Nic Carter, co-founder of CastleIsland Ventures, posted on the X platform that elliptic curve cryptography (ECC) is on the verge of being eliminated. Whether it is 3 years or 10 years, this era is over and we must accept this fact. The only thing that matters is how quickly blockchain developers realize that they need to introduce mutable cryptography into the network. This will of course require a complete reimagining of how these systems work. Today, encryption mechanisms are hard-coded into the system, but this will have to change. Ethereum people have realized this. Others still seemed paralyzed by fear. Unless things change quickly, the price of ETH/BTC will begin to reflect this divergence in priorities.

Google: We are developing a post-quantum cryptography migration timetable with the goal of completing it in 2029

On March 26, Google announced the 2029 time node and plans to complete the migration of post-quantum cryptography (PQC) to ensure data security in the quantum era. Google said that last month we called for building security for the quantum era before future quantum computers can break existing encryption algorithms. This new timetable is formulated to adapt to the migration needs of the post-quantum cryptography era after comprehensive consideration of quantum computing hardware research and development progress, quantum error correction technology, quantum decomposition resource measurement and other factors. Quantum computers will pose a major threat to current cryptographic standards, especially encryption algorithms and digital signature technology. The threats faced by encryption algorithms already exist, that is, "store first, decrypt later" attacks; while digital signatures face future threats, and the transition to post-quantum cryptography needs to be completed before the advent of quantum computers (CRQC) that pose actual cryptographic threats. That’s why we’ve adjusted our threat response model to prioritize the migration of post-quantum cryptography to our authentication services—a key step in upgrading cybersecurity and digital signatures. We recommend that other technical teams adopt the same strategy.
