In 2020 79% of companies on the web have suffered from DNS-based attacks*, it generally results in application downtimes, stealing of sensitive information, and often brand damage. Those numbers are a direct consequence of the Domain Name System (DNS) architecture inherited from the 20th century. It is very prone to hacks because it relies on a chain of centralized and fallible services and operations: registrars, DNS servers, TLS certificate authorities, DNS lookup request etc. The dappy network is a public and decentralized alternative to the regular web and DNS. Dappy browser implements a zero-trust strategy. It does not ever interact with a unique private service, but rather it connects to a network of independent agents, and has a consensus layer at the browser level. The system is backed by blockchain technology and offers superior levels of trust, integrity and security than those of regular web.

Ultra secure web applications and name system
  • Javascript has no network access by default, authorized servers must be explicitly declared (whitelist).
  • HTTPS only (HTTP + encryption with TLS).
  • No DNS, the name system is on the blockchain.
  • No certificate authorities, encryption certificates are on the blockchain.
  • Network of independant agents, with no attack point and no leader for "DNS" lookups and blockchain requests.

Multiple requests performed with Dappy
New paradigm for request, with no single points of failure

Legacy web relies on a chain of trusted centralized services (DNS servers, domain name registrars, certificate authorities etc...) . The dappy network is decentralized, just like a blockchain platform, many agents who don't trust one another necessarily, are co-responsible of file distribution. There is no unique trusted services.

Many services into one

A Dappy user delegates the network and server security to the Dappy network members who are co-responsible of the platform. He does not own a physical server. The ownership of a name replaces web hosting, encryption certificate (TLS) and domain name.

Decentralized name storage and management
Name system on the blockchain

Dappy is an alternative to the DNS system, domain seizing is not possible because the ownership of a name is recorded on the blockchain. Purchase, expiration and resale are handled by the smart contract, in a decentralized manner.
