Welcome to the Polis Chain, home of the Polis Project and its amazing community. We hope this helps you to get started, see you on our chain!
The Polis Chain is the evolution and the current home of the Polis Project. It is a EVM compatible blockchain that focuses on secure and fast payments. It relies on a system of 19 validators that are elected through the POSDAO consensus mechanism, and that append blocks to the blockchain through the use of Open Ethereum's implementation of Authority Round (AuRa).
The POSDAO consensus algorithm is smart contract based and allows POLIS token holders to either stake their coins to create a validator candidate, or delegate their stake into a candidate/validator to show support. The POSDAO algorithm chooses the 19 validators from the candidate pool with the most staked amounts at the end of each epoch (120960 blocks, a week). The selected validators will be tasked with keeping the chain secure for the next epoch, receiving transaction fees and block rewards as an incentive for their work.
Here you will be able to find the codebase for the Polis Chain.
Polis is the main asset on the Olympus Network. It allows users to pay for transaction fees, as well as transferring value stored in Polis within the network. As the Polis Chain is EVM-compatible, meaning it is capable of executing smart contract code, executing this type of code requires the executor to pay some fees, which are tightly related to the code being executed, this fee can also only be covered in Polis.
At the beginning of the project Polis was running on a proof of work, DASH fork, that then switched to its own Proof of Stake implementation in 2018. At the beginning of 2021, Polis became a BEP20 token on the Binance Smart Chain to take advantage of the ever-growing supply of DeFi projects, and finally, in September 2021 it became its own chain again.
If you have Polis from any of the above mentioned periods and protocols you are eligible to have your funds migrated into the new chain. Please consider reading our migration guide and consider joining our Official Discord Server to request official support.
