Analysts warn future quantum machines could disrupt both cryptography and mining economics Concerns over quantum computing and Bitcoin are evolving beyond fears of hacked wallets. New analysis suggests that sufficiently powerful quantum computers could threaten not only private keys, but also Bitcoin’s mining and security model, raising broader questions about the network’s long-term resilience. How Quantum Computing Could Challenge Bitcoin Bitcoin relies on two critical cryptographic systems: Elliptic Curve Digital Signature Algorithm (ECDSA) for transaction security and SHA-256 for proof-of-work mining. Advanced quantum computers running Shor’s and Grover’s algorithms could, in theory, weaken both. This creates two distinct risks: the…

Second blob-only upgrade expands rollup capacity and supports lower transaction costs Ethereum’s scalability received another upgrade after developers implemented the second Blob Parameter-Only (BPO) hard fork, increasing the network’s blob limit from 15 to 21 blobs per block. The change, activated at 1:01:11 UTC, marks another step in Ethereum’s long-term plan to scale efficiently while maintaining network stability. What the Blob Limit Increase Means for Ethereum Blobs are data units designed to help layer-2 rollups batch transactions more efficiently. Each blob holds 128 kilobytes of data, allowing Ethereum to now process up to 2,688 KB per block. This enables rollups…
Investor feedback delays exclusion, but broader index rule changes remain under review Michael Saylor’s Strategy received short-term relief after MSCI confirmed it will not immediately remove digital asset treasury companies from its global indexes. The decision sparked a sharp after-hours rebound in Strategy’s shares, highlighting how closely markets are watching index eligibility for crypto-heavy firms. MSCI said it will continue including digital asset treasury companies, defined as firms where digital assets account for 50% or more of total assets. The index provider cited strong investor feedback and the need for additional analysis before making structural changes. However, MSCI also signaled…
Protocol flaw led to asset duplication, network halt, and governance-led recovery The Flow Foundation has released a detailed breakdown of a December 27 protocol-level exploit that resulted in approximately $3.9 million in confirmed losses. The incident stemmed from a technical flaw that allowed counterfeit tokens to be duplicated on the network before being contained. According to the post-mortem, the attacker exploited a vulnerability in Flow’s Cadence runtime. The flaw allowed certain assets to be duplicated instead of properly minted, bypassing supply controls. Importantly, the exploit did not drain or access existing user balances, but instead created illegitimate assets onchain. Validators…
Decentralized messaging app gains traction as users prepare for possible internet shutdown One of the developers behind Bitchat, a decentralized messaging app linked to Jack Dorsey, has publicly dismissed Uganda’s threat to block the platform ahead of the country’s upcoming presidential election. The response comes as downloads surge amid fears of a potential nationwide internet blackout. Uganda’s communications regulator recently stated it has the technical capability to disable Bitchat, downplaying the app’s impact. The warning followed reports that opposition supporters were installing the app as a contingency tool, recalling past elections when authorities cut internet and social media access. Bitchat…
Bankers warn yield-bearing stablecoins threaten deposits and local lending A coalition of US community banks is calling on lawmakers to amend the GENIUS Act, arguing that a regulatory gap allows yield-generating stablecoins to compete unfairly with traditional bank deposits. The push highlights growing tension between banks and crypto platforms as stablecoin adoption accelerates. In a letter sent to the US Senate, the Community Bankers Council, representing more than 200 community bank leaders, urged legislators to tighten stablecoin rules. While the GENIUS Act explicitly prohibits stablecoin issuers from paying interest, the group argues that some firms are bypassing this restriction by…
New benchmarks provide regulated exposure to stablecoin and real-world asset infrastructure MarketVector Indexes has introduced two new investment benchmarks focused on stablecoin technology and real-world asset (RWA) tokenization, alongside the launch of two exchange-traded funds (ETFs) from Amplify ETFs. The move reflects accelerating institutional interest in blockchain-based financial infrastructure as adoption continues to expand. Stablecoin and Tokenization Benchmarks The newly launched MarketVector Stablecoin Technology Index tracks companies involved in stablecoin issuance, payments, and settlement systems. In parallel, the MarketVector Tokenization Technology Index focuses on firms building platforms and infrastructure that support tokenized real-world assets, such as blockchain-based representations of traditional…

US investors receive cash rewards as Grayscale’s Ethereum Trust ETF becomes the first spot crypto fund to offer staking payouts. Grayscale has announced its first staking rewards distribution for the Ethereum Staking ETF, marking a milestone as the first US-listed spot crypto ETP to pay out earnings from on-chain staking activity. Shareholders of the Grayscale Ethereum Trust ETF (ETHE) will receive approximately $0.08 per share, with eligibility based on holdings recorded at market close. Grayscale enabled Ethereum staking for its funds in October 2025, utilizing institutional custodians and third-party validators. Unlike typical Ether rewards, the payout is converted to cash…
Pilot project explores sustainable greenhouse heating using liquid-cooled mining servers Bitcoin mining hardware maker Canaan has launched a 3 megawatt proof-of-concept project in Canada that combines cryptocurrency mining and commercial agriculture. The initiative aims to demonstrate how waste heat from high-density computing can be reused to support year-round tomato production in cold climates. The pilot is located at a greenhouse facility in Manitoba and uses 360 liquid-cooled mining servers deployed across four containerized modules. Instead of releasing excess heat into the air, the system captures it through a closed-loop heat-exchange process and redirects it to preheat water for the greenhouse’s…
