Butterfly is a decentralized communication protocol built on Bluetooth Mesh × Proof of Connection (PoC).
It enables people to create verifiable real-world social connections without relying on the internet, centralized servers, or traditional identity systems.
Butterfly is not a social app.
It is a foundational protocol layer that turns real-world interactions into verifiable, composable Web3 primitives.
Core Technology: Bluetooth Mesh + Proof of Connection
Butterfly is powered by two fundamental components:
1. Bluetooth Mesh Networking
Butterfly forms ephemeral, peer-to-peer mesh networks between mobile devices, enabling:
- Internet-free communication
- Serverless coordination
- Naturally decentralized node topology
- Physical-world proximity as a trust anchor
For the first time, human interactions can be captured and validated cryptographically—without central authority.
2. Proof of Connection (PoC)
PoC is Butterfly’s native cryptographic primitive.
It verifies that:
Two users were physically present and connected within a specific time, distance, and signal band.
PoC functions as:
- A foundational identity primitive for Web3 social
- A building block for decentralized social graphs
- A sybil-resistant “real human” proof
- A proximity-based trust layer for apps, games, wallets, or L2s
- A new RWA category: Real-World Social Connections
Data Architecture: Verifiable, Composable, Trust-Minimized
Butterfly does not output accounts or profiles.
It outputs atomic connection events that external systems can consume or compose.
This includes:
- Connection Hash
- Timestamp
- Device Signature
- Mesh multi-hop path
- Proximity and signal proofs
- PoC validity proofs
- Optional zk-compressed variants
The result is a privacy-preserving, interoperable social graph engine that developers can build upon.
Privacy & Security by Design
Butterfly’s architecture is built around cryptographic privacy:
- No centralized data storage
- All events encrypted locally
- Only the user can access their structured PoC data
- Support for zk-friendly proof compression
- Graph generation without identity exposure
- Non-reversible, non-linkable proof layers
Butterfly validates connections—without revealing identities.
A Composable Protocol Layer for Developers
Butterfly is designed as a protocol, not a product.
Any Web3 application can integrate PoC-based logic to unlock real-world context.
Butterfly can power:
- Decentralized social networks
- Wallet reputation systems
- DID frameworks
- On-chain games and mini-apps
- Growth and loyalty protocols
- Sybil-resistant reward systems
- L2 or app-chain user verification
- Proximity-based interactions
Developers can combine PoC with their own logic to create new forms of social experience or trust models.
Why Butterfly Matters
Web3’s core challenge in social has never been UI—it has always been:
- distinguishing real humans
- verifying physical interactions
- establishing trust without identity exposure
- creating a social graph that cannot be faked
Butterfly provides the missing primitive:
a decentralized, privacy-preserving layer for real-world social connections.
No platforms.
No centralized graphs.
Only verifiable interactions that users own.
Butterfly is building the communication substrate for the next era of Web3 social—
a world where connectivity itself becomes a cryptographic resource.
