Blockchain.com

Ben Reeves, Nicolas Cary, and Peter Smith built Blockchain.com at a moment when Bitcoin was still a fringe experiment followed by a small community of developers and cryptographers. What began as a blockchain explorer — a tool for visualizing transactions on the Bitcoin network — evolved over more than a decade into one of the world's largest crypto platforms, with over 80 million wallets created and a product suite spanning consumer and institutional services. The original problem Blockchain.com solved was a lack of transparency: there was no simple way for anyone to verify what was happening on the blockchain, making it difficult to build trust in the system. The explorer made that information accessible, contributing meaningfully to the credibility and understanding of the nascent ecosystem. From that data platform, the company expanded into custodial wallets — allowing users to store, send, and receive cryptocurrencies — and then into exchange, yield products, and institutional services. The business model layers multiple revenue streams: trading fees, exchange spreads, and institutional products — primary exchange, custody, lending — where volumes and margins are higher than in retail. The customer base is correspondingly dual: consumers looking for straightforward wallet access and a fast entry point into crypto markets, and institutional operators seeking liquidity, regulated custody, and market infrastructure. Blockchain.com has navigated multiple crypto market cycles — the 2017 bull run, the 2018 collapse, the 2020-2021 surge and subsequent correction — maintaining relevance through the depth of its brand and the historical value of its on-chain data. Headquartered in London, it is one of the few crypto operators with a consolidated regulatory presence in Europe, an increasingly valuable asset in a sector where compliance has become a clear dividing line between serious long-term players and purely speculative ones.
