Social Activity Token: The Value and Interaction Carrier of Decentralized Social Networks
The Social Activity Token whitepaper was written and released by the core project team in Q4 2025, aiming to address the pain points of data silos and uneven value distribution for users on Web2 social platforms, and to explore a new paradigm of social interaction in the Web3 era.
The theme of the Social Activity Token whitepaper is "Reshaping Social Value through Decentralized Incentives." Its uniqueness lies in the proposal of the "Proof of Social Activity" mechanism, implemented via smart contracts to quantify user contributions and distribute value; its significance is to empower users with sovereignty over their social data and behavior, laying a new foundation for incentives and collaboration in the Web3 social ecosystem.
The original intention of Social Activity Token is to build a decentralized social network led by users and co-created and shared in value. The core viewpoint elaborated in the whitepaper is: by tokenizing users' social behaviors and contributions, combined with community governance mechanisms, to achieve fair capture and distribution of social value, thereby stimulating more authentic and meaningful social interactions.
Social Activity Token whitepaper summary
What is Social Activity Token
Social Activity Token (SAT for short) was a cryptocurrency project aimed at building a decentralized social network. You can think of it as a "digital community pass," operating on the Ethereum blockchain, like a special vehicle running on Ethereum's "digital highway."
The core goal of this project was to address some of the pain points of traditional social media platforms, such as the overuse of user data by companies. SAT hoped to redefine social media interaction by creating a decentralized social platform called "The Sphere," emphasizing user privacy and security. On this platform, SAT tokens functioned as internal "points" or "currency," which users could use to conduct transactions or purchase goods and services on the platform.
Project Vision and Value Proposition
The vision of Social Activity Token was to build a trustworthy decentralized social network. Through the "The Sphere" platform, it aimed to provide a private social media experience with integrity, a decentralized marketplace, and advertising features. Simply put, it wanted users to enjoy social fun while having better control over their data and digital assets, rather than being controlled by centralized companies. It's like turning a "theme park" operated by big companies into a "public garden" managed by community members with transparent rules.
Technical Features
Social Activity Token (SAT) is an ERC-20 standard token based on the Ethereum blockchain. ERC-20 is a technical standard for creating tokens on Ethereum, ensuring that SAT tokens are compatible with other tokens and wallets in the Ethereum ecosystem. You can think of the ERC-20 standard as a "universal language" that allows different digital assets to recognize and circulate with each other in the "digital world" of Ethereum.
Tokenomics
The total supply of SAT tokens is reportedly capped at 1,000,000,000. However, some sources indicate that the current supply is about 470 million, with a circulating supply of about 127 million. The project team once planned to allocate the tokens as follows: 60% for application development, 15% for marketing, 15% for the company, 5% for legal affairs, and 5% for security.
The main use of SAT tokens is as a utility token within its decentralized social platform "The Sphere," facilitating transactions and the purchase of services.
Roadmap (Historical Milestones)
According to available information, the development history of the Social Activity Token project can be traced back to:
- 2016: Development of "The Sphere" platform began.
- 2017: Application development started.
- February 12, 2018: Initial Coin Offering (ICO) of SAT tokens launched.
- April 9, 2018: ICO completed, raising a total of $2,000,000, with an exchange rate of $0.14 per SAT at the time.
- Q4 2018: "The Sphere" platform launched as a fully decentralized social network.
Since the official website is offline, we are currently unable to obtain more detailed future roadmap information for the project.
Common Risk Warnings
When learning about Social Activity Token (SAT), there are several risk points that require special attention:
- Project Activity and Information Transparency Risk: Since the official website `sphere.social` is offline, it is very difficult to obtain the latest project progress, whitepaper, or team updates. Lack of transparency is a major risk for cryptocurrency projects.
- Liquidity Risk: SAT tokens are currently traded on only a few exchanges (such as YoBit), with very low trading volume, which means buying and selling the token may be very difficult and price volatility may be high.
- Technical and Operational Risk: The long-term success of a decentralized social network project requires continuous technical development, community maintenance, and security. If the project team is no longer active or lacks funding, these aspects may face challenges.
- Market Risk: The cryptocurrency market itself is highly volatile, and the price of any token may be affected by market sentiment, macroeconomics, and the project's own development.
Please note: The above information is for reference only and does not constitute any investment advice. Be sure to conduct thorough independent research and risk assessment before participating in any cryptocurrency project.
Verification Checklist
Although the official website is offline, we can still try to perform some basic verification in the following ways:
- Block Explorer Contract Address: The contract address for SAT tokens is
0xc56b13ebbcffa67cfb7979b900b736b3fb480d78. You can check this address on Ethereum block explorers such as Etherscan to view token holder distribution, transaction history, and other information.
- GitHub Activity: According to earlier materials, the project once had a GitHub link. You can try searching for the relevant GitHub repository to check code updates and development activity.
- Social Media: The project once had social media channels such as Medium, YouTube, Reddit, Bitcoin Talk, and Telegram (@SphereOfficial1). You can try searching these platforms to learn about community discussions, but please note that the information may be outdated.
Project Summary
Social Activity Token (SAT) was once an ambitious decentralized social network project, aiming to solve the data privacy and centralization issues of traditional social media through blockchain technology. It completed its ICO in 2018 and launched "The Sphere" platform. However, given that its official website is currently offline and trading activity is low, there is considerable uncertainty about the project's current status and future development. For anyone interested in SAT, it is strongly recommended to conduct in-depth research and risk assessment before making any decisions, and to treat existing information with caution, as it may not be up to date.
