As of my latest update, there is no specific, widely available information on a "Blum Airdrop" event. It's possible that the airdrop you're referring to could be related to a new or upcoming project, or a lesser-known one.
Airdrop events typically have an official announcement or listing on the project's website or their social media channels. I recommend checking the following for up-to-date information on any airdrop:
Official Blum website or social media (Twitter, Telegram, Discord, etc.)
Crypto Airdrop aggregator websites (such as Airdrop Alert, CoinMarketCap, or CoinGecko, which often list active airdrops)
Crypto news websites (such as CoinDesk, The Block, or similar outlets that report on cryptocurrency events)
If you have more specific details (like the full name of the project), I can try to assist you further.
