Europa was developed by Calle, creator of the Cashu electronic money protocol.
Payments go directly to the operator via Lightning or Cashu, without an intermediary.
Calle, the developer behind the Cashu protocol, launched this May 28 in Europe, a decentralized VPN marketplace built on Nostr. The platform allows independent operators to list their servers, set their own prices and receive payments directly in Bitcoin, either through the Lightning Network or Cashu, without the platform intervening in the transaction.
According to the official site of the Europa projectthe user browses the directory, chooses an operator and pays once for the time or amount of data needed: an hour, a day, a gigabyte. Once payment is confirmed, the operator delivers a standard WireGuard or OpenVPN configuration file. When the package runs out, the connection is closed without additional charges or automatic renewals.
Europe It does not store payment data, does not store cards, and does not require the user to create an account to purchase access. The optional registration on the platform works only to publish recommendations and reports, and is done through a Nostr identity, compatible with other applications in the ecosystem.
Street, who spread the news on Xis the pseudonym of the Austrian developer who created Cashu, an “electronic cash” protocol built on Bitcoin that allows private transactions inspired by David Chaum’s digital money system. His previous work in financial privacy is the direct antecedent of the Europa tool.
Independent operators and reputation in Nostr
The project proposes a model where each operator manages its own infrastructurewrites its own no-logs policy and responds directly to its users. Europa functions as a directory, not as an intermediary: it does not touch the money or guarantee the operators.
The reputation system, according to the site, runs on public Nostr events. Recommendations come from accounts that the user already follows, not from editorial ratings nor paid positioning. Europa explicitly warns that operators are not its employees and that it is up to the user to evaluate who they trust.
The protocol is in the public domain under license CC0 and the source code is available under the MIT license, allowing third parties to build alternative directories on the same basis.
The developer from Europe argues that this is architecturally relevant: if the platform makes bad editorial decisions, users can migrate without losing access to the underlying market.
