Capital One Seeks Blockchain Patent for 'Collaborative' Authentication Tool
In a patent filing released Thursday, Capital One set out a blockchain system its says allows secure user authentication across multiple platforms.

U.S. banking giant Capital One is working on using blockchain technology to usher in more convenient and secure user authentication methods for instances such as banking security.
In a continuation of a patent application submitted to the U.S. Patent and Trademark Office (USPTO) back in June 2017, Capital One sets out a blockchain system that will receive, store and retrieve encrypted user authentication data, according to a filing released Thursday.
The proposed idea is described as "a distributed, non-reputable record of authentication interactions" that allows users to authenticate themselves across multiple platforms, but limits how much personal information is shared between them.
In effect, the method retrieves identification data on a user when they commence the authentication process (assuming the user has a profile set up). The system will authenticate or reject the user based on the received authentication information, but the user data itself is kept securely on the blockchain.
The claimed invention is said to potentially reduce "time and resource burdens" for institutions when on-boarding new clientele. Furthermore, the filing adds, it would be a boon for users that may "resent" having to repeatedly authenticate themselves as they move between different institutions.
Thus, Capital One says, both institutions and clients "may therefore benefit from a collaborative authentication system that handles authentication interactions for multiple institutions."
One business-focused use case for the invention is stated as fulfilling "statutory or regulatory requirements, such as 'Know Your Customer' requirements," which most financial institutions around the world are legally mandated to abide by to reduce the risk of money laundering.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.
What to know:
- KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
- This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
- Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
- Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
- Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Gold tops $5,000 as bitcoin stalls near $87,000 in widening macro-crypto split: Asia Morning Briefing

Bitcoin’s onchain data points to supply overhang and weak participation, while gold’s breakout is priced by markets as a durable macro regime shift.
What to know:
- Gold’s surge above $5,000 an ounce is increasingly seen as a durable regime shift, with investors treating the metal as a persistent hedge against geopolitical risk, central bank demand and a weaker dollar.
- Bitcoin is stuck near $87,000 in a low-conviction market, as on-chain data show older holders selling into rallies, newer buyers absorbing losses and a heavy supply overhang capping moves toward $100,000.
- Derivatives and prediction markets point to continued consolidation in bitcoin and sustained strength in gold, with thin futures volumes, subdued leverage and weak demand for higher-beta crypto assets like ether reinforcing the cautious tone.
