I mined PoW and now do PoS. I love it. Now I'm wodering if any PoS mined coin has segwit?

I still love PoW but it's almost useless for small start up coins. For bitcoin PoW works amazingly. I think bitcoin should remain PoW for as long as possible. At some point I would assume it has to switch to PoS but maybe not.

Another scenario might be where a bunch of PoS blockchains with fast transactions form in addition to bitcoin. Those blockchains would sync again for more security on the PoW bitcoin blockchain.

Electricity rates don't centralize mining, infact the difficulty of gpu mining can't be centralized , even if you have the large investment budget you can't setup a gpu mining farm like what we see in asics farms , gpu is the best and most healthy mining requires alot of effort,handling and experience , not just a plug and play , some hardware knowledge and calculations is required , and i wish bitcoin can be gpu minable again.

Why couldn't you set up a large, industrial warehouse full of GPU's? One, with a big budget and low cost power, can not only get bulk discount on the GPU's but mine at a lower cost than the home-miner. Seems to me that even GPU mining would become centralized like this ASIC era.

still makes sense to use GPU power for ETH and ZEC mining, and yes, I do wish BTC could be mined on GPUs again but that is just wishful thinking. lol.

cpu coin are also bad, and worse than asic, because a random dude could use aws instances to own a large amount of hash in no time and centralized the mining activity
Well, is a GPU coin also bad then? A random dude can use AWS GPU instances to own a large amount of hash in no time.

no they are not as efficient as cpu aws instances, they are far worse, inf act you don't see it often used, instead aws instaces are perfect for cpu coin, but they will centralized the hashrate too much and kill the coin

I can't comment on mining cryptocurrency with AWS, but I've had a lot of luck running hashcat on Amazon P2 instances.

i don't care about miners and their investments in hardware. i care about the health of bitcoin itself. if a pow change improves that then i'm all for it, but i don't really see how centralisation can ever go away now so it's kinda pointless.

if a pow change allows a downgrade in machinery then deep pockets buy more of that machinery than anyone else.

the industrial miners would still have the cheapest power, premises and labor.


You're first mistake was going to /r/bitcoin and expecting something coherent. Stay away from that place. It is nothing but garbage. If you really want to stick to reddit, go to /r/btc.

did you write that for a bet?

Its was far more disturbing when asics first came online, i regret that pow change didnt happen in start. I know a lot of people have they money
in asics and for that reason dont want algo change, but as it is, whole bitcoin community is in the hands of few asic producers, which is one of the worst scenarios possible.

Holy crap,someone gets it!!! CENTRALIZATION,you guys cry about it,but buy right into it!!!

Let the Corp miners have Bitcoin,mining at home has been over for awhile now,get some GPUs & lets get an ASIC resistant coin going along with Bitcoin  Wink

Here's hoping the algo change DOES happen to Bitcoin & we can go back to a time where EVERYONE had a chance to mine & take part in Bitcoin  Cool

If we could restart, how would you change it to prevent centralization? Centralization is largely due to low cost power, ASIC's and access to ASIC's aside.

asic are indeed the culprit, and always lead the centralization, because when you have something that hash so fast and can be produced by the same company who hold the big farm, you now that this is not decentralized anymore

cpu coin are also bad, and worse than asic, because a random dude could use aws instances to own a large amount of hash in no time and centralized the mining activity

the only good solution is always and only be the gpu mining, and to prevent asic indefinitely you can just change regularely the algo, maybe the code need to be done in a way to not force an hard fork everytime you want to change the algo to prevent asic mining

One can imagine increasing the block size limit from 1MB to 2MB (or any other value) whilst capping the size of transactions to say 1MB.

My understanding after 6 months involved in the space is that bigger blocks lend towards greater centralization due to increased costs of running nodes etc (storage, bandwidth).

For this fact alone I would never support a block size increase if there were other viable options available.
That certainly would be a problem with a substantial size increase, but there is another more immediate problem even at only 2MB blocks - the quadratic sighash scaling problem. It's possible to DoS the network with transactions that are very heavy handed in input/outputs for their size leading to block verification that can take a very long time to complete. The 1MB block that took 25 seconds to verify a while back on fast hardware was an example of that in action at only 1MB blocksizes. The code that does the verification is much more efficient now but still would have taken 11 seconds to verify. Double the size of that and you have a block that takes almost 45 seconds to verify. 6MB blocks and you have blocks that can take longer than the average time between blocks of 10 minutes. Slower hardware would hit that limit at even smaller block sizes. Segwit transactions scale linearly with signature hashes so 1MB of signatures for segwit transactions are a lot faster than 1MB of normal transactions, and linearly for 4MB of transactions, which is the maximum possible allowed with segwit as currently coded. That 4MB of transactions would take less than 1MB of normal transactions to verify. Note that most blocks are NOT that sighash heavy but the fact remains that it is a mechanism to DoS the network.

Holy fork, that's scary. Thanks for this info CK, well explained.

I think POW will never work for crypto coins.


edit

fucked up POS WILL NEVER WORK

Just a minor fuckup, never mind  Cheesy

Overly specialized hardware is the problem. Still remembering FPGAs? Probably you do. Or GPUs?
I know this is hard to swallow.

the problem is that LN alternative are also centralized with their HUB, at least from what i understood, it seems that you can't preserve the current decentralization if you want to fix the block limit/scaling issue

if they cna coem up with something better would be better but there is no time anymore, now the choice is based on what is less worse, not on what is ideal
I didn't say anything about LN. Most people think all the transactions will go to LN which is also completely wrong. To start a lightning channel one must create a regular transaction and then only can LN transactions occur, BUT LN will only work for microtransactions. It's not going to be possible to use it for transactions larger than .042 btc. There will still be heaps of on-chain transactions and consequently transaction fees for miners. If LN increases the userbase of bitcoin dramatically by making the proverbial 'cup of coffee transactions' possible by the general public without dumping them all into the blockchain, the overall transaction fees ending up in miners' pockets will go up substantially anyway. Furthermore, most types of LN transactions can still be implemented even without segwit so it's not like signalling segwit is voting for LN. Even if segwit doesn't get activated, LN will be implemented.

Read more about some of the most common misconceptions about LN and mining here:
https://medium.com/@rusty_lightning/miners-and-bitcoin-lightning-a133cd550310#.skccp131t

If miners weren't so quick to jump to conclusions and make wild accusations BU would never have even been considered and subsequently the threat of a hard fork and PoW change wouldn't ever have been discussed. Either way I doubt a hard fork and PoW change are going to happen anyway.

in the past i remember they said that they were prone to increase the size of the block to 2mb, apparently they changed their mind later...
It's okay to change your mind once you investigate the change and see that it is actually a bad idea to implement it. Too many people are obsessed with a plain block size increase as being some kind of simple change that carries with it no dangers, which we know now is actually completely wrong.

My understanding after 6 months involved in the space is that bigger blocks lend towards greater centralization due to increased costs of running nodes etc (storage, bandwidth).

For this fact alone I would never support a block size increase if there were other viable options available.
