Dark Web

The Dark Web is a small, encrypted layer of the internet reachable only through anonymizing software such as TOR, which routes traffic through multiple relays to hide a user's location and identity. Unlike the "deep web" (any page simply excluded from search indexes, such as a private banking portal), the Dark Web is deliberately hidden and often hosts marketplaces, forums, and services that operate outside normal legal oversight.

Cryptocurrency became central to this ecosystem because it lets buyers and sellers transact without a bank intermediary. Early darknet markets such as Silk Road, shut down by the FBI in 2013, settled almost every trade in Bitcoin, using multi-signature escrow wallets to hold funds until a buyer confirmed delivery. Later takedowns of markets like AlphaBay and Hydra showed the model was resilient rather than fragile: vendors and buyers simply migrated to successor platforms, and total darknet market cryptocurrency flows kept growing, reaching an estimated $2.6 billion in 2025 according to blockchain analytics data.

Because Bitcoin's ledger is public, investigators increasingly trace transactions back to real-world identities once funds reach a regulated exchange that requires identity verification. This pushed many markets toward privacy coins like Monero, whose ring signatures and stealth addresses obscure sender, receiver, and amount far more effectively than Bitcoin.

Not all Dark Web activity is illicit: journalists, whistleblowers, and users facing censorship also rely on it for anonymous communication, which is why access itself is not illegal, only what is bought or sold there.
