According to Cointelegraph: Ocean mining pool has denied allegations made by Bitcoin wallet provider Samourai Wallet concerning the censorship of certain Bitcoin transactions. Samourai Wallet accused Ocean of censoring Whirlpool CoinJoin and BIP47 notification transactions starting from December 6. They also implicated Block and X (previously Twitter) co-founder Jack Dorsey, who is an investor in Ocean, in an alleged "hostile action".

Samourai Wallet further accused Luke Dashjr, Bitcoin Core developer and Ocean founder, of having previously implemented transaction blacklists and censorships, suggesting a long-standing intention to do so. The wallet provider criticized Dashjr's enforcement of a 46-byte limit to the OP_RETURN function instead of 80 bytes, alleging that this change allows Ocean to exclude privacy-enhancing transactions.

Dashjr has rejected these claims and suggested that the issue may lie in a bug in Samourai Wallet's software rather than being an intentional policy implemented by Ocean. He asked the wallet provider to address the issue "on their end". The allegations have sparked a debate within the crypto community, with some siding with Samourai Wallet and others suggesting that they should address the purported bug in their software.

The wallet provider maintains its accusations and asked the crypto community not to allow Dashjr and Ocean to evade responsibility.
