What data does the bitcoin community & blockchain if truth be told log concerning the miners themselves, comparable to hardware-specs/OS/hashing-rate/and so forth.?
None of this is logged. Miners might make a selection to make themselves publicly identified, and/or to put up stats/details about their mining setups. However none of this is completed on the community/blockchain degree, in truth the bitcoin protocol calls for no data from miners. Some miners make a selection to incorporate some figuring out data within the coinbase transaction extranonce, however there’s no requirement to take action, and in addition no explanation why to think that the guidelines printed there may be in truth fair, in any case.
So far as the bitcoin community is anxious, a miner merely must put up a legitimate block to the community to be able to prolong the chain.
So in case you travelled again in time and sought after to take part as a miner, you could possibly simply wish to post a legitimate block to the community, which might be imaginable although you have been the use of fashionable ASIC {hardware}. All upgrades to the bitcoin community were backwards-compatible comfortable forks, so that you would not have a lot bother growing a traditionally legitimate block (although it’s essential to simply run legacy device to create block templates, that it’s essential to then hash on the use of your fashionable {hardware}).
Notice: for the reason that the legacy community would not pay attention to soft-fork rule adjustments, you’ll in all probability should be cautious concerning the kinds of transactions integrated to your block. As an example, in case you integrated a transaction that integrated segwit outputs, the opposite community nodes would not perceive the (fashionable) regulations governing the spending of the ones transactions (ie, they might most likely be stolen because of being ‘somebody can spend’ within the eyes of legacy nodes).
Would somebody even understand that one thing was once atypical?
Given the many-orders-of-magnitude enhancements that fashionable ASICs have over legacy {hardware}, we might be expecting that the time-travelling miner may most likely discover a majority of blocks extraordinarily briefly, till the community issue adjusted to account for this. After a problem adjustment, the time-travelling miner would nonetheless assumedly discover a majority of blocks, however on the anticipated charge of 10 mins on moderate. Different miners at the community would understand, since their percentage of blocks could be a great deal decreased (although it would not essentially be transparent that this was once because of a unmarried new miner contributing an enormous quantity of hashpower).
If the time-travelling miner sought after to hide their place of energy, they may merely cycle their mining setup off and on, to be able to now not win ‘too many’ blocks.
