You want to look at the arrival times that are logged by various entities. You can e.g., get it via the mempool.space API, and 0xb10c has a repository where he collates block arrival times from various nodes (unfortunately, it was last updated three months ago, so these blocks are not found there yet).

Likely yes, but impossible to know for sure. The block after that was found by Foundry USA. It would seem that they happened to receive the SBI Crypto block first.

The MARA block was found at 00:54:09 UTC.

The SBI Crypto block was found at 00:54:32 UTC.

Miners can of course have an inaccurate clock but let's check:

 of both SBI Crypto and MARA tends to be very close to UTC:

So it is likely that the times are indeed correct.

Even though the MARA block was found 23 seconds 

 the SBI Crypto block, MARA still lost the block race.

EDIT: On second thought, looking at the block template update intervals: (

) MARA and SBI Crypto both update their block template in ~30 second intervals. A 23 second difference is still within that time frame. So hard to say when exactly these blocks were found.

Or it was the next block found that determined the outcome?

The next block always determines the outcome.

Likely yes, but impossible to know for sure. The block after that was found by Foundry USA. It would seem that they happened to receive the SBI Crypto block first.

But sure, let's investigate a bit:

The MARA block was found at 00:54:09 UTC.
The SBI Crypto block was found at 00:54:32 UTC.

Miners can of course have an inaccurate clock but let's check:

The `ntime` of both SBI Crypto and MARA tends to be very close to UTC:
https://stratum.work/template/SBI%20Crypto
https://stratum.work/template/MARA%20Pool

I used https://www.epochconverter.com/hex to convert the hexadecimal `ntime` to a human readable format.

So it is likely that the times are indeed correct.

Even though the MARA block was found 23 seconds **before** the SBI Crypto block, MARA still lost the block race.

EDIT: On second thought, looking at the block template update intervals: (https://stratum.work/timing) MARA and SBI Crypto both update their block template in ~30 second intervals. A 23 second difference is still within that time frame. So hard to say when exactly these blocks were found.

The next block always determines the outcome.
