During the launch of the Fractal mainnet, UniSat encountered a technical challenge. Specifically, block height 2 was incorrectly used as a merged mining block, contradicting the current node strategy that requires blocks 1 and 2 to be unpermissioned mining blocks. In response to this issue, UniSat's founder and CEO, Lorenzo, took immediate action, noting that the team is working diligently to resolve the problem. He stated that UniSat's development team is actively addressing the issue with node behavior to ensure system operation's normality and stability. It is expected that UniSat will soon release a new node version to solve the current problem and enhance user experience. This incident highlights UniSat's meticulous approach to technical details and its high regard for user interests.
