Step-by-step Guide for StratumV2 Solo mining on  DEMAND

download (or build) patched bitcoind binaries from here https://github.com/Sjors/bitcoin/releases/tag/sv2-tp-0.1.2
⛏️⛏️After, click on bitcoin-sv2-tp-0.1.2-x86_64-linux-gnu.tar.gz to download the patched bitcoind that support StratumV2 (this is the Linux binary)
⛏️⛏️https://github.com/Sjors/bitcoin/releases/download/sv2-tp-0.1.2/bitcoin-sv2-tp-0.1.2-arm64-apple-darwin.tar.gz (this is the MAC binary)
run the patched bitcoind with this command:
⛏️⛏️ ./bitcoind -sv2 -sv2port=8442 (you MUST use this port otherwise the proxy will not work)
⛏️⛏️you can add other flags if you need them
⛏️⛏️the node will not enter a ready state for mining until any block is found on the network.
⛏️⛏️⛏️Note: Once you launch the node and the chain is synced, you'll need to wait for a new block before launching the proxy.
wait for the chain to sync
download or build demand all in one proxy from here https://github.com/demand-open-source/stratum/releases/tag/DEMAND
⛏️⛏️Click on Release (right hand side) to find the proxy
⛏️⛏️This is the proxy: demand_all_in_one_sv2-x86_64-linux-gnu and download
⛏️⛏️⛏️NOTE: only available for MAC and LINUX
Once downloaded, run or execute it with ./demand_all_in_one_sv2-x86_64-linux-gnu -a bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh <- this would be your valid bitcoin address where you would receive your mining reward
⛏️⛏️Multiple miners are able to mine to one address
Run it
As soon as you see INFO demand_solo_all_in_one::translator: Connected to Upstream! ....\
⛏️⛏️ point your miners to ip_address_of_the_machine_running_the_proxy:34255

Congratulations miner! You are now helping maintain bitcoin mining healthy and decentralized with StratumV2 DEMAND.

You may enter the command - - help for other options

You can skip all this and solo mine sv1 with this endpoint: mining.dmnd.work:1000

Thank you
DEMAND team

We have released an sv2 proxy called demand_all_in_one the binaries are available here:
https://github.com/demand-open-source/stratum/releases/tag/DEMAND

You can use it for testing the demand job declaration functionality, for now only available on the solo pool.

Since is not yet stable the proxy  fallback   to ckpool if it the user hash rate that read from the pool is 0 for more than 3 minutes.

In order to try block declaration you have to run a TP https://github.com/Sjors/bitcoin/releases/tag/sv2-tp-0.1.2

the is a patched bitcoin node so you run like it but you have to add the sv2 options
-sv2 -sv2port=8442  -sv2interval=30 -sv2feedelta=2000 port must be 8442

otherwise the proxy will not work
when the TP is ready you chain as synced and you see in the log sv2 thread start you can launch the proxy
the proxy require only one argument the address of your solo pool proxy_bin -a [address] for example demand_all_in_one_sv2-x86_64-linux-gnu  -a bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh

then you can point your miners to ip_of_the_pc_that_is_runing_the_proxy:34255`

Well stratum is about 15MB a day - to compare to

Since it's related to it, under the suggestion of @neutraLTC, I share my work also under this topic.

I'm going to build a testing & benchmarking tool to evaluate Stratum v2 (SRI) protocol performances in different mining scenarios.
I made a draft documentation of the tool here: https://docs.google.com/document/d/1uckx4os7laxKkJIc8QBOm5HlQuKcEHkvQa4szlAqcM8/edit#heading=h.c4oi55seebkm.
I'd love to get as many feedback as possible from miners and pools operators. My goal is to validate the tool docs, especially the metrics mentioned there, before starting to build it.

I also created a survey to collect feedback and suggestions here: https://47r5o81bk9b.typeform.com/to/bBgHVBl3.
Feel free to share it with miners/pools you know, it would be really appreciated 🙏

Thank you

One of the things that StratumV2 CAN do is allow the individual miners to create their own block template. So you as a miner can submit a block that you want when you find a share that will mine a block.
(not a 100% accurate way of describing it but it works for this explanation) The other miners and the pool have zero say as to what is included in the block that you submitted.

Now.
1) It's a feature of Stratum V2 the pool does not have to support it.
2) As others have pointed out the block that the core client comes up with will maximize fees.

This all sounds crazy to me. Maybe I just don't get it

It's gonna be the pool that ends up censoring the transactions surely? Individual miners, or even large farms of miners aren't going to give a fuck about what transactions go in where, they just want the maximum reward for spending all that money on equipment and electricity right?

If it was up to the invdividual miners, say if there are 1000 miners on a pool and 50% of them could not accept a midgetpornmeme transaction and 50% could, or even if there is one pool that doesn't accept a particular transcation but another 4 pools do, I mean whats changed?

So the pools are going to end up doing it, but will it make any difference, and if not why bother doing it unless its just to promote your own pool/code/software and cut some extra profit somewhere on the side for yourself as a company.

Maybe the pool will have a page where you can vote, but then who controls what the other pools do, if they all vote the other way then it doesn't matter.

The idea is fine, it is doable, but, a big but would be the miner's actual reward that you can take to pay other miners, if a miner has a hashrate of say 1ph, that earns him 0.1 btc a day, then he sends a block template that loses 1 btc, even if they take his entire reward it won't cover the losses.

So the pool caps this by doing
If (X - Y =< Z )
{accepted}

Else {reject}

Z could either be his hashrate payout or other collateral.

It is doable, but it is a lot of work which could be avoided, so i don't think many pools will even consider doing it.

For pooled mining it also depends on where fees are at the moment and how much is being given up.
Going from 5 to 0.5 is a big deal
Going from .1 to .99991 when spread across a few hundred miners is not even a worry.
What would be is going from X to 0 because someone made a mistake with the template and mined an empty block.

Everyone has their own pain point.

Makes you wonder if you can code the pool to say the optimal block was X but you did Y his cost Z. So now your reward is lowered by Z and given to the other miners.
This way if you paid me to mine your TX I keep the money and nobody else at the pool can complain since they got paid.

Just a thought.

I don't -- i won't try to force anyone not to use it, all am saying is, as a miner I would NOT use a pool that allows human beings to generate their own biased template that would result in a loss of profit for me.

I also explained scenarios of which I would engage in creating my own templates, if all pools are forced to ban certain listed addresses, and said pool would pass the responsibility to me to un-censor those addresses, I would, I would also accept it if another miner does it for the sake of fighting forced censorship, but doing so for any other reason means you are guaranteed to make me lose profit and I do not want to lose money, I also don't know many people who are willing to.

The moment a miner sees his pool making 0.5 btc on fees while there is a potential of 5 btc sitting on their mempool, it would be pretty hard to keep the miner, no sales pitch in the world would fix that, money lost is money lost.

Solo pool, ya great idea -- not solo, i would pass.

Again, i am only stating my opinion, if others are willing to use pools that give users the ability to create transaction biased blocks, be my guest, this would allow the pool is use (that uses default block template) to make even more profit.

You are not the others. This is the difference between a market, and a free market. You can choose not to buy the cheapest thing, or not do the highest profit trade. You may simply like the other stuff and nobody can force you to get the "most profitable" if you don't want to.

This is giving people choice, you are free to use it or ignore it. Nobody forces you what template you like. The pool can enforce their own preferences or leave it entirely to the miners.

You seem to not get the "optional" and "proposal" parts of block templates. What, do you think if the humans don't make a choice, there won't be anything? If you don't pick anything the usual still occurs. But now people are allowed to bias it as they see fit. To each their own, a truly free market.

As a miner solo with your node you always had this power, but the pools seized this, now its returning back to them. How can you even oppose this?

Sorry, you won't maximise your profit.
This is not some old guy getting pennies to manage cheap funds.
You are replacing good block fees with lower fees - that's a loss.

For the case were people are trying to save on txn fees, they wont save on fees if they pay you more than blocks currently require.
So in these cases (the vast majority) you are losing out.

You wont be getting more unless you are deceiving people.
Anyone can adjust their transaction to get it into a block.
RBF has been available for all transactions for a while now.
Child pays for Parent has been around way longer even.

Hoping people are ignorant of this and hoping they will pay you a fortune coz you won't tell them ... yep help make bitcoin look bad.
Yep most people will do anything for money ...

Free market code selected transaction blocks is also perfect democracy, it's superior to human democracy, the code doesn't know who you are, whether you are sanctioned by the U.S, or anything about your transactions, it checks a set of rules to validate the transaction and if everything checks out -- you are in.

people-selected transaction blocks are subject to being biased because human beings are just emotionally driven creatures, a U.S based miners could ban all known Chinese addresses just for political bullshit, the Chinese miner could do the same to the American miner, and the list goes on, eventually, the nation/people with the most hashpower could end up censoring nations with less hash power or none at all, pretty much how the U.S sanctions other countries today.

Not saying they will always end up in a censorship -- but they can, unlike how things are with code based democracy.

Why replace code democracy with human democracy? any person who is rational enough and is driven by a business mentality would reject this, as a miner I want my pool to extract the most fees possible without being biased, I wouldn't give my hard-earned hashrate to someone with an unstable brain who would reject a transaction that pays 1000 sat per byte for whatever political reason while accepting other transactions with 1 sat/byte.

For a solo pool, it would work great, for PPLNS (bad idea) PPS+ (bad idea since the transaction fees are still going to be paid in PPLNS), and FPPS ( a bad idea for the pool -- miners won't be affected since fees are paid ).

Giving people freedom to censor transactions, is, obviously, still censorship.
Trying to put a marketing spin on it, doesn't change that.

Pools have this ability, but most of them realise the stupidity of reducing their income if they were to do this.
V2 opening bitcoin to censorship by default, so that govt's can more easily enforce rules on bitcoin mining, sounds like a really bad idea to me ...

Just so you know, I'm not the operator of Braiins Pool nor i can make any decisions about it, but you are in yours. I think people being able to propose their templates is democracy which is the very opposite of censorship. If anything, it is moving down to the miners the choice of what block templates they like. Ocean and Demand by adopting V2 and experimenting with the block template proposal are showing the way for decentralization and freedom in my own personal opinion.

Because you are the sole owner of it, yes, you have the power to provide the same level of democracy. Its only unfortunate that you require registering an account for solo mining, but lets leave your own pool stuff in your own thread. I applaud Demand here.

Delusioins dude

Your V2 transaction bias is the same idea as what Luke wanted with GBT instead of Stratum.
You're not even original.

No one ever implemented it in GBT (not even Luke) and GBT died.
Why? Coz it's censorship - a bad idea against the ideals of Bitcoin.
Bitcoin core simply gathers all transactions available and ensures you get the best fees in your block.

Wanting transaction bias - i.e. censorship of transactions - removing transactions you don't like - will mean lower fees on PPLNS pools.
I bet you wont point out on your pool that with V2, any blocks found will only contain the transactions allowed by the miners of the blocks found.
Your marketing spin (lies) will mean most your miners wont even realise this.
Though if your pool is already censoring transactions, I guess it doesn't really matter.
But even if you are not already doing it, it will be soon enough.

Which was why I said

If you are REASONABLE in what you ask in terms of cost for acceleration you will get some people.
NO, you are not going to make tons more, but you will have the ability to make more coin.

You even said it yourself they are "mostly irrelevant" that is not "totally irrelevant"

I used to work with a commodities broker who went after the little sales more or less on his own time (not company time) everyone else looked for the whale. He took all the little trades he could get that generated pennies in terms of extra pay for him. Could probably made more as a dishwasher at the bar vs what he made doing this. BUT every once in a great while, since he did do these small trades a big one happened to come through one of those clients or friends of a client or so on.

So yes, for months and months like him you could be accelerating penny TXs for a few more pennies, but then someone who did fuck up and made a non RBF low fee TX is going to show up on your doorstep and ask for help and pay you a nice fee. Not a way to make a living, but a nice way to at times make more.

But, you have your pool you can run it your way. Others have their pools, they can run it their way.

I wish @neutraLTC best of luck and hope they succeed.

Imagine miners not wanting to push spam to the blockchain, this coming from the guy that falsely accused another person of c p, and said c p is being pushed spearheaded by the exploit publicly demonstrated by ordinals but followed by others...

In the end, you are against freedom, of people wanting to propose their own template blocks. You have for years been saying bad things about V2 and not even bother to see the code, which is even in your favorite game/meme social media known as Discord.

It happened exactly like i told you a couple years ago, keep looking the other way and saying falsehoods and lies. V2 is here to stay and is being adopted. That you are too lazy to do it in your pool, no one cares.

No, I'm correct.

As I said, and will repeat, "maximise the fees in your block"

However, what you completely failed to point out was the fact that your non-block payments are ever so rare transactions.
They exist coz someone either underpaid the transaction fee, or simply wanted to pay less than the current block requirement.
If they paid the right fee they will be in a non-bias block.

So since these are so rare, and one of the two causes is people trying to pay less block fees, you aren't gonna be making it rich trying to find them.

Bitcoin is currently around 1/2 million transactions a day, these rare 'mistake' transactions and 'I want it cheaper' transactions are mostly irrelevant.
On top of that the 'I want it cheaper' transactions are clearly not gonna work to your advantage.

Ya I was talking about the general usage of it, not in regards to solo mining or this particular pool.


if 1 user gets lucky to hit a block that has a potential of 3 BTC in fee rewards but then because he is stupid or gets paid for doing so -- the other miners would end up losing profit, I mean if a single entity (a pool) can make you lose profit, it's only going to be worse when thousands of other users can do the same, I personally wouldn't use any pool that allows this -- I doubt anyone in their right mind would.

Transaction-biased blocks are only good for one purpose, the pool won't be able to censor certain transactions, but for this to actually work, other miners need to have a say in this, they need to accept the block template proposed by each other and to evaluate it otherwise, it will certainly fail and nobody would use them.

Yes, but here there are 2 things to keep in mind.
1) For now it's a solo pool so it's just you.

2) If they do go to a PPLNS or whatever in the future, this part of StratumV2 means the the miners, not the pool, control what goes into the block. So if I pay you to mine a TX and you mine it it's between you and the other users of the pool not the pool and it's users.

And yes, VIA probably keeps the fees.
