Introduction to Sirr
Sirr is a decentralized encrypted messaging application with built-in wallet functionality. It combines end-to-end encrypted messaging with blockchain technology to provide anonymous, secure, and censorship-resistant communication.
What is Sirr?
Sirr exists to make communication untraceable. It's an encrypted communication tool with anonymity and security as its first principles. We advocate for "Communication Freedom" and "User Sovereignty"!
Key Characteristics
- Anonymous: No phone number or personal information required
- Secure: OpenPGP end-to-end encryption
- Encrypted: All messages are encrypted by default
- Censorship-Resistant: Decentralized architecture with no single point of control
Why Sirr is More Secure Than Other Messengers?
Sirr is not just an "app" - it's a decentralized encrypted communication infrastructure.
No Central Server
Unlike WhatsApp and Telegram, Sirr has:
- No central server storing user data
- No core node that can be shut down
- No storage of user profile information or communication content
Anyone Can Run Communication Nodes
Ultimate privacy - anyone can run a Sirr communication node, forming a truly distributed communication network. All your data can be stored on your own cross-border node, beyond anyone's censorship.
Seamless Cross-Node Communication
Users on different communication nodes can communicate freely and seamlessly across servers, without needing to know which node the other party is on.

OpenPGP: Verifiable Security
Sirr uses the OpenPGP encryption standard, which has a proven track record:
- Born in 1991: OpenPGP was first released in 1991, based on the revolutionary Pretty Good Privacy (PGP) encryption program
- Widely Adopted: Widely used in global email encryption and file encryption scenarios
- Battle-Tested: Over 30 years of verification by the global cryptography community
- Highly Secure: Not a single plaintext leak due to encryption being cracked
OpenPGP uses public-private key pair encryption technology:
- Only the recipient can decrypt messages using their private key
- Even if the encrypted content is intercepted, it cannot be decrypted
