Thank you. The first one is presumably all Satoshi though, not multi-sender, given the block numbers of the 50 coins from coinbase that led to the 1, the 10 and the 50 (Hal started mining at block 78) and there is the Patoshi pattern to allow guessing Satoshi's blocks.

<p>Is there a claim for the earliest multi-sender transaction?</p>
<p>Maybe Satoshi and Hal tested it?</p>

I think amaclin's answer illustrates that we can't easily distinguish between multi-sender transactions and single-sender multi-input transactions with certainty. It might have been better to ask about what murch called *"obvious coinjoin transactions"* in murch's answer to your earlier question on this theme.

Obviously my question requires some extra knowledge on top of transaction data, which is usually not available, but for very early transaction I expect some comments on forums to provide the extra data.

Is there a claim for the earliest multi-sender transaction?

Maybe Satoshi and Hal tested it?
