French Bitcoin treasury company Capital B has acquired 376 Bitcoin (BTC) for 25.3 million euros ($29.5 million), bringing its total holdings to 3,521 BTC.The purchase was funded after Capital B completed roughly 30.1 million euros ($35 million) in capital raises, including a private placement backed by investors Adam Back and TOBAM, according to a Monday announcement.The company bought the Bitcoin at an average price of 67,182 euros apiece, with Swissquote Bank Europe executing the purchase and Taurus providing custody.Capital B has spent a total of 309.4 million euros acquiring its Bitcoin treasury, at an average cost of 87,878 euros per BTC. The purchase moved the company to 25th among publicly traded companies by Bitcoin holdings, according to BitcoinTreasuries.net.The latest acquisition was Capital B’s largest since September 2025, when it purchased 551 BTC for 54.7 million euros. The company also holds 61 BTC for operational purposes, which it keeps separate from its treasury reserve and excludes from its Bitcoin-related performance metrics.Related: Satoshi-era Bitcoin wakes after 16 years of dormancy as 600 BTC movesTop BTC treasury firms continue accumulatingWhile companies including K Wave Media and Sequans Communications have moved to unwind their Bitcoin treasuries, others are continuing to accumulate.Japan-based Metaplanet acquired 2,823 BTC during the second quarter for about $222 million, bringing its holdings to 43,000 BTC. The company paid an average of roughly $78,850 per Bitcoin during the quarter and now ranks as the third-largest publicly traded corporate Bitcoin holder, behind Michael Saylor’s Strategy and Twenty One Capital, according to BitcoinTreasuries.net.In August, Sweden-based H100 Group more than tripled its Bitcoin holdings after acquiring Norwegian companies holding 2,455 BTC. The all-share deal lifted H100’s treasury to 3,506 BTC, making it Europe’s second-largest publicly traded corporate Bitcoin holder at the time. Capital B’s latest purchase puts it 15 BTC ahead of H100, though both remain behind Germany’s Bitcoin Group SE with 3,605 BTC.Strategy, the world’s largest corporate Bitcoin holder, also resumed buying in August after a two-month pause, acquiring 4,603 BTC for $370 million. The purchase brought its holdings to 845,050 BTC, acquired for a combined $63.3 billion.Top 30 Bitcoin treasury companies.

Pineapple Financial has moved more than $1 billion in residential mortgage records onto Injective, a layer-1 blockchain focused on financial applications, as part of a broader effort to migrate its historical loan portfolio onchain.Pineapple plans to eventually migrate more than 29,000 funded mortgages worth over $10 billion onto the network, Injective said Friday. Each mortgage is represented by an onchain record tied to the underlying loan file, rather than being repackaged as a new mortgage security.The records contain more than 500 data points, including loan-level information designed to support verification, audit trails and risk analysis. Pineapple’s dashboard shows that the migration now includes 2,079 mortgage records, up from 1,259 when the initiative launched in December 2025.PAPL0, which tracks the mortgage records onchain, has an asset market cap of about $1.1 billion, up 48.2% over the past nine months, according to Token Terminal data. The tokens represent mortgage records rather than ownership of the underlying loans.PAPL0 market cap on Injective.

Pineapple stakes INJ from the treasury, with Kraken serving as a primary validator for the holdings.Related: The 5 types of real world assets being tokenized fastest onchainReal estate tokenization gains momentumReal estate has become a growing focus of the push to bring traditionally illiquid assets onchain, where tokenization can make property or investment interests easier to divide, transfer and access.In June, Apex Group joined Goldman Sachs, Archax and LRC Group on a tokenized real estate fund whose shares are issued as digital tokens through Goldman Sachs’ Digital Asset Platform. The structure gives investors blockchain-based ownership of fund shares, rather than simply recording property data onchain.Dubai has also expanded its real estate tokenization efforts. In February, the Dubai Land Department launched the second phase of a pilot after about $5 million in property had been tokenized, with transactions recorded on the XRP Ledger.However, tokenized real estate still remains a small part of the broader real-world asset (RWA) market. The sector has about $226.5 million in distributed value, up 11.7% over the past 30 days, compared with $38.8 billion across tokenized RWAs tracked by RWA.xyz.Tokenized real estate.

Post-quantum infrastructure company QuFi Network has launched a verification platform designed to protect digital assets against future quantum computing threats without requiring changes to existing blockchain settlement networks.The platform separates verification from settlement, using a decentralized network of nodes to validate transactions with post-quantum cryptography before they are settled on existing blockchain networks.QuFi also launched uBTC, a proof-of-concept that applies the verification system to Bitcoin (BTC) and is currently operating on Bitcoin Testnet4. The uBTC system verifies BTC collateral and generates cryptographic proofs governing how value moves between settlement environments, while redemptions ultimately settle as standard Bitcoin transactions.The platform uses three post-quantum cryptographic standards — ML-DSA-65, SLH-DSA and ML-KEM-1024 — for digital signatures and secure key exchange.QuFi said the external verification layer is intended to avoid the added storage, bandwidth and computing demands that can come with adopting larger post-quantum signatures directly on individual blockchains.Related: Crypto’s first quantum attack will look like unexplained breach: Quantus founderCrypto ramps up quantum defensesThe platform arrives amid a series of recent efforts to prepare blockchain networks for potential quantum computing threats.In August, StarkWare tested a quantum-resistant Bitcoin transaction on mainnet without requiring a fork. However, the transaction took hours of computation and cost roughly $150 to $200, and its nonstandard format required direct submission to a miner.Jonas Nick announces the BIP SHRINCS proposal on Aug. 26. Source: Jonas NickThe same month, banks and regulators across Europe, the Middle East and Asia joined a pilot testing post-quantum wallets and onchain transfers using ML-DSA-65, one of the same cryptographic standards incorporated into QuFi’s platform. Meanwhile, the Ethereum Foundation dropped the Poseidon hash function from its planned post-quantum architecture in favor of established alternatives such as SHA or BLAKE.Bitcoin developers are also exploring protocol-level defenses. In August, Blockstream researchers published a Bitcoin Improvement Proposal for SHRINCS, an experimental post-quantum signature scheme designed to reduce the size and performance costs associated with quantum-resistant signatures.The approach comes with trade-offs. SHRINCS uses stateful signatures to reduce their size, requiring wallets to track previously used signing keys. The scheme remains in an early stage without a completed security proof, and its design adds complexity and potential user failure modes.Magazine: Bitcoin’s new quantum defenses, 18.9M SOL cancelled: Hodler’s Digest
