General Information
Block Size | Block Speed | Gas price | Patchset | Native token | Network ID |
~17,000,000 Gas | 5 sec | 1 -10 GWei | Berlin | POA | 99 |
To mitigate an ongoing denial-of-service attack, validators decided to increase the gas price to a range between 1-10 Gwei. Each validator can determine their own value within this range.
