How Sign Works
No Central Control
Sign operates on a decentralized network of nodes distributed globally, free from control by banks or governments.
These nodes collaborate to verify attestations and token distributions, ensuring system transparency and attack resistance, giving users greater autonomy and enhancing network resilience.
Blockchain Core
Sign's infrastructure is built on an open, immutable digital ledger that records all attestations and token distributions.
Transactions and attestations are grouped into blocks, linked through cryptographic hashes to form a secure chain.
Anyone can view the records, establishing trust without intermediaries.
The omni-chain architecture enables cross-chain interoperability, further enhancing performance and accessibility.
Ensuring Fairness
Sign Protocol utilizes smart contract-based verification mechanisms to validate attestations and prevent fraudulent credential claims.
Validators maintain network security through running nodes and processing attestations, contributing to the integrity of the credential system.
Its innovation includes cross-chain attestation compatibility and efficient token distribution management.
Secure Transactions
Sign employs public-private key cryptography to protect transactions and attestations:
- Private keys (similar to secret passwords) are used to sign attestations and authorize token distributions
- Public keys (similar to account numbers) are used to verify ownership and authenticity
This mechanism ensures fund security and maintains verifiable transparency in credential verification.
The platform supports multiple blockchain standards including ERC-20, BEP-20, and BASE, enabling flexible deployment across different ecosystems.
Circulating Supply Overview
As of January 20, 2026, Sign's circulating supply stands at 1.2 billion tokens, with a total supply of 10 billion tokens. The circulating supply represents 12% of the total supply, indicating a controlled release mechanism. The token operates across multiple blockchain networks including Ethereum, BNB Smart Chain, and Base, utilizing ERC-20, BEP-20, and BASE standards respectively.
