The listed addresses hold an estimated 3.7 million BTC, valued at about $285 billion, according to Sani, the founder of Bitcoin onchain analytics platform Timechain Index.

The founder also noted that most of the old Satoshi-era tokens are currently sitting in Pay-to-Public-Key (P2PK) output formats, while the plaintiffs only sent legal notices to the corresponding hashed public key under Pay-to-Public-Key-Hash (P2PKH) formats, which often hold no value.

This could undermine the claim that proper notice of abandonment was given to the holder, since plaintiffs sent the legal notices to the empty P2PKH addresses, while the actual BTC balance sits in unnotified P2PK scripts.

Castle Labs' lead research analyst agreed, adding that the messaging attempt was “structurally defective” because it was sent to the address formats no longer used by the targeted wallets. Sending a small transaction via the OP_RETURN function would be “similarly ineffective” as it only works with active recipients monitoring their wallets.

The over 39,000 wallets named in the lawsuit hold Bitcoin that are considered dormant, or lost, meaning that they haven’t been circulating onchain for multiple years.
