Topic: A solo Bitcoin miner just won block 718214 reward worth 6.25 $BTC - page 3. (Read 859 times)

With the current exchange rates, it is like $270,000. I am not sure how much he/she might have spent on the mining equipment, but it should be lower by a magnitude of 100x-1,000x. So this reward is like hitting a lottery jackpot. LOL.. how this miner would have felt after coming to know about the reward? BTW, a few other factors might have contributed to his luck. China hashpower is completely wiped out due to hostile government action. And then there is the ongoing unrest in Kazakhstan, which has knocked out another 15% of the global mining contribution.

solo.Ckpool
is "buzzworded" as solo. but not actually solo..
its configuration is not that the USER has to have a bitcoin node to look at its mempool and collate transactions into a block and create its own blockheader and coinbased rewarding itself. and then independently going through all the possible nonces, extra-nonces and extra-extra-nonces of its own solo block

instead ckpool:
collates the transactions and manages which asic gets which work.
sets the reward arrangement
deciding to only pay itself 2% and the wining asic 98% (instead of collecting 100% and later sharing to all asics)
ckpool does send new work for the block template ck pool creates.


ck pool users:
just need to connect their asic to ck pool with a username and password and start hashing

as the ckpool websote itself says:

its not solo because the 'stratum' is managed by the pool. not by the user
its not solo because that requires the user to have a bitcoin node to collate the transactions and create a template themselves.

the onlything 'solo' about it is the payout(if your luck) is 98% 'solo'
but the block template management is very much pooled

You are referring to the BetterHash and Stratum V2 protocols that give the hashers more control over what transactions go into the blocks.

Regardless, whether or not the hashers are working on the same block with the same coinbase is irrelevant. The basis of a pool is that if anyone in the pool finds a block, everyone in the pool shares the reward. If that is not the case, then it can't be considered to be a pool.

there are only so many nonces, and (timestamp) extra-nonce
an average asic can run through these in seconds.
a pool needs to adjust coinbase data(extra-extra-nonce) to give more varied work over the ~many minutes of a block solve session. and do this for each asic.

a pool of say 13,000 asics will have 13,000 'new work' with different coinbase every few seconds, meaning over the average ~10min blocksolve session thats probably about 4million different 'work' with different coinbase extra-extra-nonce

each asic gets a basic template of their owners blockheader including owners address. so that there is some variance to the work they all do as a pool
EG if all asics didnt have one of the outputs different from other asics and the OP_Return started at 1 to a for all asics. they would all be doing the same work as each other at the same time(waste of time).

ckpool example:
COINBASE (Newly generated coins)        38HRDQeecdfQnCyrnLEtKJGnEsrLG3XUCt      6.14274623 BTC
                                                           1PKN98VN2z5gwSGZvGKS2bj8aADZBkyhkZ  0.12536216 BTC
                                                           OP_RETURN ?x?x?x?x?x?x?x?x?x                  0.00000000 BTC
and each few seconds. the pool changes op return for more variance to work on

in other pools, its the same thing, all thats different is the payout
COINBASE (Newly generated coins)        1PKN98VN2z5gwSGZvGKS2bj8aADZBkyhkZ  6.26810839 BTC
                                                           OP_RETURN ?x?x?x?x?x?x?x?x?x                  0.00000000 BTC
                                                           OP_RETURN ?x?x?x?x?x?x?x?x?x                  0.00000000 BTC

in pools that pay out to a pool owner only(later shared). their 'variance' in this example is instead of using a asics address as one output they use a random op return per asic(like an asic ID, unique to each asic). and then another op return as a an extra-extra-nonce to give that asic more work every few seconds

some pools just have one op return(small pools) and allot 1-> xtrillion to one asic. and then xtrillion -> x*xtrillion to another asic, within the range of the limit of how much entropy the op return allows(large number)
and if the pools asics work through all this variance then the pool can do different tricks by changing the transaction arrangements(order)

but in all cases. its not the asic or its user making these coinbase adjustments or blockheader hashs to then give the asic work to churn through. its the pool that is making these header/coinbase adjustments,
all thats different between usual pools and ck pool is the payout. ck gets 2% fee. and pays rest to one user. other pool gets 100% and pays out to all users

but they all work based on the data management done by the pool

Are you sure about this?
I heard that the newer versions of stratum allow each miner some kind of flexibiliity

Not a pleb anymore, that much bitcoin can easily turn someone's life around for better or for worse. I am not that good with technicals though so I don't get why they have this kind of reward in the first place. Can someone explain to me the technicals behind this stuff in a dumbed down fashion?

A mining pool is referred to a server where miners share the same work and get paid for their contribution. In CK pool (regardless of the name) the work is not shared, so it can't be called a mining pool. In a mining pool, all miners are working on the same exact block with the same exact coinbase.
In CK pool each miner is doing its own work on its own block with their own unique coinbase. CK pool is just providing a node and "header production" service!

solo.ck is actualy a pool.

heres its own pool stats


here it explains within the POOL there are 2050 users with about 5-6 asics on average each
also worth noting that the average actual hashrate breaksdown as being only 2thash each, so some people are using some very crappy old asics on CK solo pool

oh and one last point. dont rely on blockchain.info's "network hashrate" or things like the btc.com pool hashrates. as those numbers are based on math of (time,difficulty,blocks found) rather than actual hashrate provided by the pool direct (such as my link shows)
ck pool is averaging at like 1200% luck for its actual hashrate right now.
its actually performing at 30peta.. but its luck of block finds is as if its performing at the math of 360peta (network guess hashrate)
...
now again to explain.
each asic owner(user) is not forming its own blockheader and adjusting its own reward share to itself. being proper solo

instead the CK pool is managing the block headers and setting the reward share. where it gives itself 2% and the uses the coinbase as an extra-extra-nonce which each user has a coinbase address, thus giving each user on the pool a variety of nonce and extra nonce to work through that are not the same hash permutations as another user
(all pools do this extra-extra-nonce varience)

all pools are collective. and change a coinbase per user/asic to give each asic varied work compared to other users.
and in all pools, a winning hash is always found by one asic

all thats different is instead of CK taking 100% and in a separate later transactions split the reward over all users. ck takes 2% for himself and then lets the winning hash user get the 98%

Now that's what I call a lucky winner. Didn't think the odds were THAT small actually (not that 1 in over a million is small) but I suppose this already pays out his cost, wonder how what his profit margin's been across all those 262 blocks found?

Anyone knows what the record is for solo block found with the most improbability (or lowest odds)?

Indeed the CK solo pool is not actually a pool.
I don’t know if it a known thing, they have a support thread here on bitcointalk.

[∞ YH] solo.ckpool.org 2% fee solo mining 262 blocks solved!

Here instead, the list of the recently minted blocks:

This is not the only one incident of solo miner solving the puzzle and getting block rewards of 6.25 btc at this time where many big mining farms are your competitors and recently there was another that happened again :


There are so many talks about them but the chances of this happening in actual is very rare but for some people might get confused that the solo miners have small setup but in actual he might be using some good hardwares that have helped him to be lucky.

But two cases in a row is indeed arousing some curiosity among members as well as miners also.

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,

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)

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.

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

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.

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.


Lol, again ~100TH/s 

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.

Someone else who is also quite lucky.

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.
