What is the Sign project (SIGN)?
Key takeaways
The Sign project allows users to create and verify digital attestations across multiple blockchain networks.
It uses encryption and zero-knowledge proofs to ensure that claims related to identity, ownership, or agreements are secure and easily verifiable across different networks.
Users can prove ownership, identity, or eligibility without disclosing unnecessary personal information.
TokenTable provides projects with a range of options to manage token distributions, such as airdrops, vesting schedules, or token releases.
Introduction
In today's digital world, proving your identity online has become more important than ever. The Sign project was created to facilitate the identity verification process for individuals and businesses, and to share personal information securely, using blockchain technology. It also helps projects distribute tokens in a smarter and more flexible way.
What is the Sign project?
The Sign project aims to meet the need for secure, accessible, and verifiable personal data in the digital world. By integrating blockchain technology, smart contracts, and privacy measures, Sign offers a decentralized approach to identity verification, ownership, and contracts across multiple blockchain networks.
How Sign Works
The Sign ecosystem consists of four main products:
Sign Protocol: Facilitates the creation and verification of attestations across multiple chains.
TokenTable: A platform for token distribution through methods such as airdrops, vesting schedules, and token releases.
EthSign: A decentralized application for executing digital agreements on-chain.
SignPass: A system for registering and verifying identities on-chain, helping users prove their identities online.
Sign Protocol
The Sign protocol is like the digital version of a notary, allowing users to issue claims regarding things like identity, ownership, or agreements and verify them. It operates across multiple blockchain networks and includes built-in privacy features using zero-knowledge proofs. Some of its key features include:
Multi-chain capabilities: Supports attestations across different blockchain networks.
Data Structure: The attestations are based on key-value pairs, making them highly modifiable with different data formats.
Privacy features: Data can be encrypted or concealed using zero-knowledge proofs, ensuring that users can prove claims without revealing underlying data.
Developer incentives: Encourage innovation by funding and supporting developers who integrate the Sign protocol.
Data security: Backup alternative mechanisms (such as Arweave storage) ensure that data is not lost, even if blockchain networks experience downtime.
TokenTable
TokenTable handles the complexities of token distribution. By using smart contracts, TokenTable can provide different distribution models:
Release: Fully on-chain schedules for token releases.
Merkle-based distributions: Efficient distribution using Merkle trees.
Signature-based distributions: Simple and low-cost procedures for claiming tokens.
Through TokenTable, projects can manage vesting schedules for tokens, conduct airdrops, and handle token releases with minimal manual intervention. Distribution models are designed to balance cost efficiency and on-chain verifiability, and can be tailored to meet project needs.
EthSign
EthSign provides a decentralized alternative to traditional electronic signature platforms. Instead of relying on traditional electronic signature services, users can sign contracts and agreements directly on blockchain networks.
SignPass
SignPass allows users to register identities on-chain and verify them, linking real personal information with decentralized identities, helping users prove status or qualifications without disclosing unnecessary private information.
Creating and verifying attestations
Attestations in the Sign ecosystem involve three parties:
Witness: The entity that issues a statement about another entity (for example, 'This wallet belongs to Alice').
Subject: The entity referenced in the attestation.
Verifier: The entity that verifies the truthfulness and legitimacy of the attestation.
Using the Sign protocol, the witness creates signed data about a specific subject, which can then be verified by any external party, according to access permissions and privacy settings.
SIGN Token
The SIGN token is the service and governance token of the ecosystem:
Total supply: 10 billion SIGN tokens.
Initial supply available for trading: 1.2 billion SIGN (12% of the total supply).
Use cases: transaction fees, governance participation, storage incentives, and community rewards.
The distribution of SIGN tokens includes free distributions for early users and community members, focusing on enhancing decentralized ownership.
SIGN tokens in the Binance free distribution program for holders
On April 25, 2025, Binance announced that the SIGN project is the sixteenth project in its free distribution program for holders. Users who staked their BNB tokens in Simple Earn or on-chain yield products from April 15 to 19 are eligible for the airdrops. A total of 200 million SIGN tokens have been allocated for the program, representing 2% of the total token supply.
SIGN tokens have been listed on the Binance trading platform with an emerging sign, allowing trading against USDT, USDC, BNB, FDUSD, and TRY pairs.
Closing thoughts
The Sign project lays the groundwork for how verifiable claims and secure token distribution can work in the cryptocurrency space. By focusing on privacy and supporting multiple blockchain networks, it can offer a flexible system that meets the needs of users, developers, and institutions alike. The project's goal is to facilitate the verification of digital interactions while safeguarding sensitive information, contributing to a more reliable digital world.
