POA Network Overview and Core Mechanism
POA Network (POA) is a public, open, and permissioned blockchain network built on the Ethereum protocol. Launched on March 6, 2017, its core feature is the adoption of the Proof of Authority (PoA) consensus mechanism. Unlike Proof of Work (PoW) or Proof of Stake (PoS), validators in the PoA mechanism are pre-selected, publicly identified, and vetted entities. This mechanism aims to achieve higher transaction speed and scalability by sacrificing a degree of decentralization, making it one of the early explorers of Ethereum sidechains to support smart contracts and decentralized applications (dApps).
Technical Features and Development History
As an Ethereum sidechain, POA Network provided an Ethereum Virtual Machine (EVM)-compatible environment, allowing developers to build using familiar Ethereum standards while benefiting from the performance enhancements brought by the PoA mechanism. Its main technical features included:
- EVM Compatibility: Allowed easy migration of smart contracts and dApps from Ethereum.
- High Throughput: The PoA mechanism achieved faster block confirmation speeds and higher transaction processing capacity by reducing the number of validators and using a pre-selection mechanism.
- Interoperability: POA Network aimed to enable asset and data flow between different blockchains. A significant milestone was the launch of the POA20 standard in 2018, which implemented the first cross-chain bridge, allowing fast transfers of POA tokens between the Ethereum mainnet and other blockchains.
- Block Explorer: In October 2018, POA Network launched BlockScout, the first fully functional open-source Ethereum block explorer, enhancing network transparency.
Project Transformation: Integration into Gnosis Chain
POA Network underwent a significant transformation during its development. According to public information, the project was integrated and transitioned into Gnosis Chain (formerly xDAI Chain) around August 2024. This transition marked the end of POA Network as an independent entity, with its technology and community resources merged into the Gnosis Chain ecosystem. Consequently, the independence and activity of the POA token have significantly decreased.
POA Token Issuance and Current Status
POA is the native token of the POA Network, used within the network to pay transaction fees and incentivize validators. Here are key data points regarding its issuance and current status:
- ICO Issuance: The POA token ICO took place on November 16, 2017, with an issuance price ranging from approximately $0.07 to $0.07961, raising about $12.6 million to $12.64 million.
- Total Supply: The maximum supply is approximately 252,460,800 POA.
- Historical Price: The all-time high price for POA token reached $1.87 (January 12, 2022).
- Current Status: As of September 11, 2026, the current price of POA token is approximately $0.0006 to $0.0007, a drop of over 99.96% from its historical high. Its 24-hour trading volume is extremely low, typically only a few hundred dollars, and the circulating supply is shown as 0 or extremely low in some data sources.
Investment Outlook and Risk Warning
Given that POA Network has transitioned and integrated into Gnosis Chain, the market activity of the POA token has almost dried up, lacking effective trading. Its price has fallen sharply from its historical high and has performed poorly over the long term. The current extremely low trading volume and market capitalization reflect low market recognition of its value and extremely poor liquidity.
Some market analyses previously made predictions about POA's short-term price movements, but the reference value of these predictions has been greatly diminished after the project's transformation and drastic changes in the market environment. Given that the token no longer has an active trading market, there are currently no reliable active trading channels for this token. For any individual seeking investment, the POA token is currently an extremely high-risk asset with almost no investment value.
