smallest hashrate to mine a block in the past 3 years

Anyone got info on the lowest hashrate that actually managed to mine a block in the last three years?

Since we can only estimate the hash power of some mining pools and there are many unknown miners with unknown hash rate, it's impossible to answer to your question. It's possible that a solo miner has found a block with a very low hash power, but we can't know how much hash rate is owned by any of individual miners.

Do you perhaps mean what is the block that dropped the hash rate the most in the last 3 years? That's 689,472, which dropped difficulty by about 28%, from 19,932,791,027,263 to 14,363,025,673,660. Otherwise, if you're asking how many hashes it took the least to solve a block, then that's unknown. In the end, it only takes one hash to solve a block.

Earlier this year a Compac-F running 350GHs hit a block on the -ck solo pool. That low enough for you?

IIRC he had about 1.75th worth of them say five sticks. Pretty good I would say.

Actually, I hit with 9 Compac F sticks attached to a HP Omen PC... Hence the name "TheOmen" but nothing more than a simple Windows PC a few high power hubs and some USB miners. My total BTC farm hashpower at that time was between 8.2 - 9.2Th but the system that hit was running 9 Compac F sticks totaling about 3.4-3.6TH.

Thus you are likely the luckiest block hitter in the last 3 years. To scale the luck my mine has had 1.5ph to 2.0 ph last 3 years and we have not hit a block. we don't mine solo we mine pps and even with 200x the hash for last 3 years no block and about 1.13 1.03 5.00 7.23 coins to his 6.3 or so for the 1 block

They say even a blind squirrel gets a nut once in a while

Well ... every single block is found by a single miner. Each block found on each pool is also found by one account on that pool. It doesn't really mean much to say that someone with a low hash rate found a block, since in reality that is how blocks are found. Or to put it another way One of Sledge's 390GH/s CompacF ferraris found a block ... and that is a single chip miner.

How do you know your miners didn't hit any block when mining to those PPS pools? it's pretty hard to keep track unless you use monitoring software that gives you alerts when one of the miners hits a block, the miner log itself would reset with every reboot so your miners could very well have hit a couple of blocks without you knowing.

I check a lot. but it is possible i missed one.

Oh you have no idea. I still laugh about me almost falling out of bed when I saw my wallet balance!

I think it is awesome someone hit with the USB stick miners! Just curious, have you added more compacs since then? Are you getting any of the new R909 pod miners? Do you have any of them mining on kanopool as well to diversify or just put them all on ckpool for a higher hash rate?

I'm currently running 40 Compac F's and 9x 2 Pacs on a private pool which is under development.  I do use CK'S and Kano's pools however both as backup pools. Both are great options. I'm not running any R909's at this time. I am however running several Apollo BTC's as well as and an ever expanding number of S19 Pros. Gotta keep hope alive!!!!

That's awesome.  Would love to see a picture or video of all that.  What is the total hashrate with all that running?

Pi3 = 10 x Compac F's = 3.75 Th/s Pi2 = 15 x Compac F's = 5.7 Th/s Pi1 = 15 x Compac F's = 5.7 Th/s Apollo1 = 6 x Apollo BTC (On Balanced) = 15Th/s Apollo2 = 6 x Apollo BTC (On Balanced) = 15Th/s Apollo3 = 4 x Apollo BTC (On Balanced) = 10Th/s Apollo4 = 6 x Apollo BTC (On Balanced) = 15Th/s Single Apollo = 1 x Apollo BTC (On Balanced) = 2.45Th/s S19APro110Th = 7 x 110Th = 770Th/s S19JPro104Th = 3 x 104Th = 312Th/s Adding this week or early next: 1 x S19APro 110Th = 110Th/s 6 x S19JPro 104Th = 624Th/s So if all goes well next week I should be pushing about 1.88Ph/s

WOW!  Is all of that solo mining or is any of it participating in other pools that have frequent payouts?

Currently all solo on a pool that's under development.

I have been asked to not give info out on this pool so I will say 1 thing I am pointing 1 s19 pro to his pool.

Actually I think its important to note that the pool which is under development is a joint effort between myself and another member of the forum.
