A weekly analysis of who, how, where and why blockchain and digital assets are being used globally in various industries
Wall Street’s blockchain surveillance problem: every trade is public - Wall Street’s rush onto transparent blockchains has created a surveillance nightmare: every transaction, wallet balance and trading pattern is permanently public. MEV bots, such as jaredfromsubway.eth, extracted millions via sandwich attacks in 2025, whilst analytics firms map institutional flows with chilling precision. Competitors track treasury positions, OTC desks and client relationships in real time, but, despite zero-knowledge proofs and private chains (Kinexys, Aztec), adoption lags due to technical friction and regulatory caution. Without privacy standards, institutions risk handing rivals a free intelligence feed, potentially stalling high value blockchain use.
Coinbase reintroduces token sales in the US with safeguards - seven years post-crackdown, the regulated “ICO 2.0” has arrived via Coinbase, trading Telegram hype for institutional KYC and mandatory lockups. Yet, structural inequities persist: VCs retain private-round discounts whilst “anti-flip” measures remain porous. And, as the SEC pilots T0 settlement with DTCC, the wall between crypto capital and Wall Street plumbing is collapsing. Banks now face a critical choice: adapt to Coinbase’s gatekeeping or lose the primary issuance and secondary trading of tomorrow’s on-chain assets.
Why 2026 financial systems must plan for smart contract failure – Blockchain-powered smart contracts remain vulnerable to logic flaws, oracle manipulation ($8.8billion losses in 2025) and emergent risks, turning localised bugs into systemic threats. Immutable code amplifies failures; resilience demands circuit breakers, pausability modules, modular design, hybrid governance and coordinated recovery frameworks. Financial systems must design for inevitable failure, embedding safeguards to contain damage and enable ethical reversibility.
Copy trading: why is the market growing so fast? - copy trading lets you mirror professional traders automatically, select who to follow, adjust allocation and stop anytime, whilst retaining full control and responsibility for your account. No one else accesses your funds. It democratises elite strategies via AI and enables 24/7 trading allowing profits in rising and falling markets. As traditional funds grapple with high costs, tokenisation and AI agents are shifting the future toward low-fee, always-on, intelligent investing.

Fasinating breakdown of how transparency became a double-edged sword for blockchain adoption. The MEV bot exploitation really shows that what was supposed to be a feature (public ledgers) turns into a strategic liabilty when every institutional trade becomes free competitive intelligence. I worked on a project where we tried zero-knowledge implementation but the performance overhead was brutal.
