^ here is your issue
meaning the rest of your topic post is about DISTRIBUTION not decentralisation.
imagine a bug needing a recall of devices. or a firmware update. if everything is core then the recall/update ends up coming from a single central point
its the same as demanding all computers only run microsoft
As far as I know, the Bitcoin core is reliably verified and no errors are detected there and will not be detected with high confidence.
As for mining, you can make a separate game with a mining unit for those who want it, but it is better to do mining on the game server. Hardware requirements for mining and game server are similar, and it is quite possible to combine it.
Although there is another option (I wrote about this earlier), you can make mining distributed over a large number of gamers (pool of gamers-miners)
In order to stimulate gamers to give the mining unit in the game to work, while the gamer does not play, you can make a special bonus that is spent while the player is playing and recovering, while the player is not playing, but the game is not closed.
1. first of all you trusting a team does not give reason to only have one. infact trusting a team and denying an option for more than one team is centralisation at its essense.
nothing wrong with you trusting one team. but denying other teams as an option is not decentralisation
oh and...
core announced a mega bug in their code that would DDos all core node at once running 0.14+ just a month ago.
2. oh your are mentioning the consoles have to connect to a server.. that again is echos of pools and centralisation..
this topic seems to sound less and less like a decentralisation effort. and more so just a way to sell games consoles..
3. within days of releasing consoles that can mine. someone with $10000 would buy a 50 consoles and hook them up as a pool
within a week someone with $1m will hook up 5000 consoles as a pool. and within a month you would see bigger investors with enough stock to have 500,000 consoles linked up as a pool. thus. all the idea of 'console' mining is doing is causing hashrate drama for a month before its back to usual of pool mining again.
4. oh and even PoS is becoming pooled. so dont think that console mining will be distributed for long, because PoW and PoS will always end up being pooled once it meets a certain threshold of greed/need.
think about it if a block is 12.5btc($63k) but only one 1 winner every 10 minutes. as soon as lets say 1million people want to mine. each user has to wait for "luck" of between 1-1mllion blocks to get $63k
they will naturally prefer to increase the odds and get a more regular income by pooling rather that a one in 20 year chance for just a one time win of $63k
5. people have already planned out putting a single asic chip into a LED WIFI controlled light bulb. thinking 'every house can mine'. problem was that other people already planned to snip off the LED filament end. and just have a rach of the asic bulb screw ends running
