A solo Bitcoin miner just won block 718214 reward worth 6.25 $BTC

[mynonce]

A solo Bitcoin miner with only ~100 terahashes per second (TH/s) of computing power has become the unlikely winner of the block mining race on the Bitcoin network. By successfully mining block 718124, the lucky miner secured the 6.25 BTC block reward plus 0.10461270 BTC fees. Congratulations!

I read about this earlier, it’s a once in a lifetime occurrence to be honest. The chances of a solo miner repeating this are miniscule. Congrats to this lucky pleb though, he had a very good day

Yes, the chances were ~ 1 in 30 years. But he/she/they kept mining ... wow.

[willi9974]

Yes nice hashrate, we hit last year two blocks on this Solo Pool.
But we used 20PHs nicehash rentals.

Best regards

[franky1]

actually its not solo mining..

what you have to realise is that with all pools. each asic can go through its nonce and timestamp extra nonce permutations every ~1 second/thash. and so pools then use the 'coinbase' transaction as an extra-extra nonce by giving each 110thash asic unique hashes to then 'work' through per 0.x second of hashing cycle.

no pool ever needs 1millions asics to compute on one 'work hash' to combine together to get a single winning hash.
instead its the large farms of asics all given lots of 'work' to churn through where only one asic comes up with a win for the pool.

all that ck pool does differently is instead of taking 100% of the reward for the pool, and change the coinbase using its own address and new output of randomness.. as extra-extra-nonce
 and after a win, then separately divide up the winnings based on shares.

it instead(the pool) sets up the coinbase extra-extra-nonce using the workers address, giving the asic 98% pool 2% of the win.

every block solution ever found, is found by a single asic.
its just the payout terms are different per pool.
ckpool just rewards that asic. rather then take 100% and share to all asics.

its just simple math.
instead of an asic getting 0.00006342% per block in one pool
its getting 98% per every 1576800th block

the work is the same no matter the pool. its just the payout arrangement is different

[Bitcoin_Arena]

I am not sure how many ASICs he had in his farm to produce such hashing power, but it makes me wonder how long he had been running the miners minus any rewards while paying for the electricity bills.

He's one guy who really had a lot of faith. Damn! It's just like winning a lottery after years of trying and never giving up.

the pool of miners was pushing 43 petahash. meaning it has 390 asics of 110thash
https://solo.ckpool.org/pool/

with bitcoins network hashrate of 165exa, its estimated that a ck pool will find a block every 26 days.
meaning every 26 days one of ck pools 'workers' asics will win 98% of that block. and ck himself gets 2%

meaning. everyone has to mine for 27 years for everyone to get a win(if workers are on 'fair' balance of random probability)
the workers do not share each win per block solved every 26day. instead per block solved goes to the specific solver.
. again in every pool there is always a specific solver(1 asic with the answer), but in most pools they all share the win even if the others never solve a block.

again. the reward sharing is the only difference, its not like other pools where everyone shares 0.0xxxx% per block found even if it was their asic that was the solver.
its that no one shares the winning apart from the block solver.

again
in all pools every block solved hash is down to one asic finding the special number out of the pool. all thats changed in ck is who gets the reward

What a lucky solo miner who got that much lucky at this time when there are big mining pools having heavy ASIC machines with so much computing power.He really got all his expenses covered with the rewards of 6.25 btc and if he holds them for long he is already sitting on the piles of funds.Great chance for him.

Oh my freaking goodness! How lucky is that solo miner. 6.25 BTC x $43k as of today = $268,750.

In the Philippines, it’s worth like 13.4 million pesos, which can be good enough to buy a big land! He landed the jackpot. I bet that solo miner is super duper happy now!

Lucky pleb: *cackles in a 1-acre mining farm*

[kaya11]

Oh my, what a lucky hit. His faith in that is incomparable. I thought solo mining isn't possible anymore as gigantic mining facilities are increasing. I have been relieved of stress, planning to sell my rigs but this came to me and decided to continue.

[stompix]

I am not sure how many ASICs he had in his farm to produce such hashing power, but it makes me wonder how long he had been running the miners minus any rewards while paying for the electricity bills.

Pretty easy, the hashrate is there it was 60th/s for 7 days and spiked to 110th/s so he must have either to s17e m20 models or twice as much in s15. Power bill of course it's according to electricity costs, take 10 cents per kWh and s17e and you have 5000$ a year.
Maybe someone who has upgraded his gear and left a few of the older ones on separate settings, I'm nearly my max allowed power for the contract if I could fit an s9 in it without going over probably I would let it mine some way, it cost you nothing extra and if you hit the jackpot that's it, the amount you gain from normal mining is peanuts anyhow.

[noorman0]

Someone else who is also quite lucky.
https://mempool.space/block/0000000000000000000859aae6845872298f1b9683e222bc77bcd7996d01f99f

Another solo miner (who had only been mining 2 days!) just mined a block worth 6.25 #Bitcoin.
The odds of this happening are 1 in 6,000

[Leviathan.007]

I do not want to talk too philosophically, but this shows nothing is impossible in this world and there is a possibility for anything that happened to this guy may not happen ever again and if you consider his/her luck between all the miners he was the one who had the chance and between all these blocks mined during these years he got the reward from this block and this show how lucky he is, but still he didn't have low hash rate power and 100 terahashes is still not low for a solo miner as far as I know.

[stompix]

but still he didn't have low hash rate power and 100 terahashes is still not low for a solo miner as far as I know.

100TH/s is single s19j or M30s+, if you go further down the line about 6 old s9 that was released 6 years ago, which in bitcoin terms would he half of a lifetime. So it's low, almost as low as you could possibly count something as mining and not calling it hobby or heater replacement.

Someone else who is also quite lucky.
https://mempool.space/block/0000000000000000000859aae6845872298f1b9683e222bc77bcd7996d01f99f

Lol, again ~100TH/s 

[dothebeats]

What are the chances? Perhaps that guy must have been doing all of these for the lulz and stuff and wasn't really expecting that they'll solve the block. 100 TH/s is so small in today's standards, that hitting something huge with it is almost impossible. Then again, this just shows you that every miner in the network is accounted for, no matter how small their contributions are. It's just that most of the time, those with lots of exerted output will be rewarded, as the system is designed that way.

[herurist]

actually I'm still not sure about the thing that solo said but whatever it is he is a very lucky person.
that's over $250,000 at current prices.
frankly I envy this person But this is the gift and congratulations your luck this year is very good and this is the luckiest thing in your life I think

[odolvlobo]

People are making this out to be some kind of miracle, but it is not.

Consider the Powerball lottery. The odds of winning it are 1 in 300,000,000, yet somebody always seems to win. That's because of the number of people that enter.

It all comes down to math. So let's do the math.

Let's assume that there are only 100 solo miners, each with 120 TH/s. That's a total of 12 PH/s. The total hash rate is 180,000 PH/s, so the probability of one of these miners winning a block is 0.000067. That is quite low; however, there are 52560 blocks each year.

The probability of one of these solo miners winning at least one block in a year is 1-(1-0.000067)⁵²⁵⁶⁰ = 3%.

It's low, but it is not a miracle. Furthermore, if we assume there are 1000 such miners, then the probability is so close to 1 that it would be a miracle if one of them didn't win a block.

[kano]

...
   "shares": 951786693123,
...

That's the only number that you can use to reliably determine the 'luck' (since the hash rates are calculated from shares but also vary over time)

Alas the pool doesn't keep proper luck statistics, so you can only get an approximation of the probability.

Anyway, since Network Diff is 'currently' 24,371,874,614,345.6
and their effort was 951786693123
then an approximation of their luck is 1 chance in (24,371,874,614,345.6 / 951786693123)
or about 1 chance in 25.6 or inverted - 3.9%
So nothing like the completely incorrect numbers being bandied around twitter by twits

However, the luck and chances are better than that, since difficulty has been rising for quite a while, so some or most of those shares would have been in a lower difficulty period and thus have higher luck in the final calculation.

--

The second user who got a block was also nothing like the incorrect luck numbers bandied around twitter by twits.
Their shares were something like "2,4xx,xxx,xxx" and again that number in relation to current network difficulty of 24,371,874,614,345.6
give roughly 1 chance in 10000 or 0.01% chance

This second calculation is all within a single difficulty change so more likely to be accurate.

--

So in all, yes lucky, but no, nothing like the random numbers people have been saying.
Does that pool owner even understand maths and statistics?  
(well he is a medical doctor, with no recognised computing qualifications at all)

again to emphasise. a CK solo pool is not actually solo.. its a pool. and in all pools the solved hash is always solved by 1 asic within the pool. no matter how the pool is described.

the only difference of CK pool is that the asic in question gets 98% rather then sharing the reward between all asics


in lottery analogy.
ck pool and antpool are both names of lottery syndicates (groups of people buying lotto tickets where only one can win)
if antpool has a winning ticket, he pays out 99% to all ticket buyers, the buyer of the winning ticket doesnt get 99% but a shared small %. and the others in the syndicates get the same small% even if their ticket was not a win.
if ck pool wins, he pays out 98% to just the buyer of the winning ticket everyone else doesnt get a shared small %

but in both cases. the lotto system runs by only 1 lotto ticket number wins per game.

the CK 'solo^TM is not true solo where an asic works outside of a pool and gets to form its own block headers of only its control and reward,
