#DiversifyYourAssets
To answer your question about whether Node number 4 that you purchased has been "unlocked", I assume you are referring to the distribution of the associated tokens (such as $CARV if you are talking about the CARV project) or its release from the vesting period. Since you did not specify the project explicitly, I will assume you are talking about the CARV project based on the context of your previous question, and I will explain the situation accordingly. If you are referring to another project, please clarify.
Regarding the CARV project:
Purchase Date: If you purchased Node number 4 a year ago (around April 2024), this means you participated in the node sales that started in May 2024 (the public launch was in June 2024, with an early sale for whitelisted participants on June 3, 2024).
Vesting and Distribution Schedule: According to CARV project information, the node rewards you with $CARV or veCARV (a non-transferable token used in governance that can later be exchanged for $CARV).
The allocated percentage for node operators is 25% of the total supply (1 billion $CARV), and it is distributed over 4 years after the Token Generation Event (TGE).
Approximately half (50%) of these tokens are unlocked in the first year, with a reduction of 25% every 6 months.
