Topic: Last block not mined by a pool? (Read 135 times)

that block reward went to a address 3KZDwmJHB6QJ13QPXHaW7SS3yTESFPZoxb
that address has received over 1600btc in 7 months

thus it is a pool or a asic farm with alot of hashpower. it just did not announce its name/brand/company to the explorers tags

based on some basic math of ~200 days and 1600btc. thats more then 1 block a day. meaning about 1% of the hashrate of the network was used to get those block rewards
..
technically there are pools(well lets just call them self managed asic farms) where they do not host for outsiders. where they only operate for their own devices.
..but now we are getting into the semantics of where is the line of whats defined as "solo"


...
as for those shouting about the CK pool.. no its not a real solo mining, because its still uses a pool with a pool manager.. and so its not a solo effort where people make their own individual blocktemplates and transaction selections.. its instead simply that the CKpool manager does the transaction selection and hosts communications with the workers and its ck pool that assigns that each of its workers gets a header with a coin reward that rewards the pool worker the majority of funds.. but the ckpool manages the rest.. so not really "solo"

in short there is still a pool involved.. its just the reward share which handled differently

the last time someone(home hobbiest) actually solo mined (ran their own software to make a blocktemplate, collate transactions, set their own reward address and broadcast the result to the network from his own node.. .. with no pool/server/manager remotely).. was a long long time ago

After reading your reply, now I'm sure that luck even works for the miners. That guy was truly lucky because it's almost unbelievable that a person could find a block with that low hash rate. It's really inspiring to know that, and thanks a lot for sharing that information. I'm sure that many people will get inspired by that because if someone with 0.000004% chance can find a block then anyone who's lucky enough can find a block with low hash rate.

I must say that such people are truly one in billions and are among the luckiest people of the world. I think there might be few more such cases, but even this one proves that luck really works, and even a miner could be lucky enough like the one in that example.

So we only need 365 of such users globally to mean a solo block every day on average.

It's not that uncommon for people to solo mine. It is essentially playing the lottery. Many will never find a block. A lucky few will and hit the jackpot, figuratively speaking.

ckpool, which is not a pool at all and actually a collection of solo miners, currently has around 2,500 miners with 0.01% of the hashrate: https://poolbay.io/mining-pool/15/solo.ckpool.org.

Here's an example of one such very lucky miner: https://nitter.it/ckpooldev/status/1485586948844826629#m. He only had 8.3 TH of hashrate, which was around 0.000004% of the total hashrate at the time. This means he had a 1 in 25 million chance of successfully finding a block. At an average of 144 blocks a day, it would have taken him ~476 years to be successful. Yet he found a block.

I just checked the blockchair.com and the information was accurate. The block was mined by a single miner, but I was thinking that how a solo miner could possibly do that in current difficulty? Either the miner is rich enough to have very high hash rate that he/she doesn't need a pool for mining of a block or it can be purely a sign of luck. Because as we all know that the difficulty changes every 2 weeks, and that might be helpful for solo miners if it reduces sometimes.

Someone with proper knowledge about it should clear out my mind that how is that possible? And, what's probability for a solo miner to mine a block in current difficulty level. Even in current difficultly level a solo miner with 7524 TH/s hash rate would require almost a year to mine a block. I have checked that using Cryptocompare Bitcoin mining calculator, but I'm not sure if that is correct in the calculation or not. Can someone please reply with a proper answer to clear my doubts about this?

You can do that on the Blockchair.com explorer. Just set the filter for "Guessed miner" to "unknown".

According to Blockchair.com, the most recent block mined by an individual miner, not associated with a mining pool, is: https://blockchair.com/bitcoin/block/792771

I'm curious to know which block was the last one mined by a miner that is not a pool. Is there a way to filter out the pools on mempool?
