According to Ai 姨, Ethos' credibility scores, which are crucial for its product offering, are dynamically adjusted based on three key components: EVM address interaction history, Twitter profile, and inviter reputation. The initial score is set at 1200 points, but using a new address or a newly registered X account linked to Ethos may result in a reduced initial score. Additionally, the reputation of the inviter can influence the initial score positively.
