(Pre-ANN) Patchcoin: A sister cryptocurrency to Peercoin

Today, we are sharing an upcoming project with the Peercoin community: Patchcoin.

The development group is a collective of Bitcoin investors who have worked quietly with Peercoin contributor @noface to build something new and useful. This process has taken several months.

Our project will combine Peercoin’s proof-of-stake strength with a fixed supply cap matching Bitcoin’s.

We view Patchcoin and Peercoin as sister cryptocurrencies – with a shared background, values, and purpose, but each having its own unique characteristics.

The entire supply – all 100% – of this project will be fairly and freely distributed to Peercoin holders. Coins will be distributed through an automated on-chain claims process.

To claim your coins in this new project, ensure that your Peercoins are stored in a personal wallet (not on an exchange) by block 795,000, approximately 17-19 February 2025.

More details will follow on 22 February if that block height has been reached.

Watch patchcoin.org for more information soon.

IMPORTANT: only @patchcoin, @noface, and @arthurwilkins are associated with the Patchcoin project on this forum. All communication will be done publicly through these accounts.

Congrats

An important question was brought up on Discord. Does the claims process support multisignature addresses? A significant number of PPC are stored in multisig addresses, so we’d just like to verify it will be possible to claim using these addresses, or if the coins will need to be moved to a single sig address during the capture time.

Given the occurrence rate of multisig addresses on-chain, they have not been a primary focus during development.
It is possible, but it would come with certain limitations compared to regular addresses and would primarily depend on making such an additional ruleset agreeable.

So would you recommend temporarily moving the coins to a regular address?

Does this mean that airdrop process is not trust-less but depends on an operator?

Yes, that would be preferable at the moment.

It is as trust-less as peercoin itself is trust-less.

I don’t understand. For example why are multisig addresses excluded if they can produce a valid transaction signature?

Because they are, purely based on their current usage on the peercoin blockchain, more of an afterthought. So I treated them as such.
Again, if there is demand, I’ll gladly spend some to ensure they are stable.

What about taproot addresses?

Btw I see two P2SH addresses in the top 10 by richlist at cryptoid.info explorer. Active.

i think they want to do airdrop on only to Peers rather than any other entity or exchange. Make sense.

Thanks @Sentinelrv for the question. We’ve added this to the pre-ANN to clear things up:

EDIT: In response to community questions: we focused on legacy PPC addresses as the most used and stable for the automated claim. If you’re certain you want to receive airdropped Patchcoins, please have your PPC in a normal address such as those in the QT wallet. We may support other address types (multisig, segwit, etc.) but cannot promise it.

There is a decent amount of coin in bech32 addresses, which is the default address format for years now. Legacy P2PKH is outdated and no longer supported by the new HD wallet, which uses sqlite db. You will be excluding anyone who first installed the wallet in the past two years or so. Just a quick search on the explorer:

If you’re using a bech32 address, you can tell by looking at the first two characters. As shown in Peerchemist’s photo example above, these addresses will start with pc. The older P2PKH address type which is currently being supported here by Patchcoin starts with a capital P.

@peerchemist is there currently any way for those on the newer bech32 address type to transfer to an older P2PKH address type, in case it doesn’t get supported?

I do not think people should be bothered with migrating to new addresses for the sake of this process. It is not convenient, and makes you lose out on coinage. It could be forcing people to make a whole new wallet for example, it is complicated. The process should instead accommodate these users and not simply disregard them.

The process is either fair or not fair, there is no in-between.

Can you please explain more about this. In Peercoin, the supply is not fixed, as POS produces new coins - whereas Bitcoin will be fixed after 21 million coins have been produced. How does Patchcoin square the difference? Thanks.

I think this will be good for Peercoin. It will attract attention and most likely drive the price up, which will attract more attention and drive the price up more, hopefully creating a little snowball effect. It’s good timing with Peercoins Flutter wallet with ROAST Coordinator. The extra attention created may also attract some more development for layer 2 smart contract applications. I would love to see a big marketing campaign by Patchcoin promoting POS. I also think the distribution of 100% of the Patchcoin supply to Peercoin holders is a testament to Peercoins sustainability. Maybe some Peercoin holders will sell a portion of the Patchcoin received and buy some more PPC, possibly increasing demand even more and increasing the price again. All this attention to Peercoin from ROAST applications, Patchcoin, POS promotion and imminent price increase will be perfect timing for the incoming industry changes. Exciting times all round.

I am very curious to see how this will work too.

IMO the fairest way to do this would be to offer ≈ 0.714 Patch to every 1 PPC

My maths below…
At block 795,000 the total Peercoin should be ≈ 29,410,000.

So 21,000,000 Patch

21,000,000 is ≈ 71.4% of 29,410,000
Hence ≈ 0.714 Patch to every 1 PPC

My maths could be way off and I guess we will just have to wait and see the white paper to see how it’s going to work.

Hopefully this offer will get some of those old PPC wallets moving and minting again.

There was a discussion on Patchcoin in Discord/Telegram a few days ago. I’m just posting a record of it in here so new people reading this thread have more information. One of the people behind the project (Arthur) was answering questions.

Sentinelrv So fixed supply Peercoin? What is it fixed at, the total supply at block 795,000?

selfwithin Peercoin supply is not fixed. Read Peercoin White Paper. They are talking about Fix supply of Patchcoin.

Looking forward to see thier WhitePaper.

PatchCoin Seems like Proof of stake coin with fix supply with faster UTX. Could be step forward for Smart Contract.

Sentinelrv lol, that’s exactly what I meant.

NPC yawn

HighLow what limited supply?

ppc is inflationary

please let me understand…the development finishes here with PPC and starts with Patchcoin? Or patcoin makes a softFork from PPC chain?

Sentinelrv HighLow, Peercoin developers (with the exception of noface) have nothing to do with Patchcoin.

These Patchcoin guys seem to be launching a fork of Peercoin, but they’re saying their fork will have a fixed supply.

And also they are airdropping their whole supply to Peercoin stakeholders, so you would need to have your PPC in your own personal wallet at the date they mentioned if you plan to claim the airdropped coins. If your coins are on an exchange or somewhere else, I imagine you’re out of luck

Peerchemist Just read the forum post by their guy.

Cybnate Re Patchcoin; Interesting approach a Peercoin/Bitcoin hybrid of kinds. Didn’t NXT/Ardor do the same thing 8+ years ago? Not sure about the deflationary aspects of it, unless there is some really good utilisation or liquidity. Will be interesting to see how this works out. Sounds like a friendly fork, so popcorn is out.

selfwithin Keywords is bitcoin investors ….

MattLM How do you secure PoS without supply inflation?

peerchemist Block producer gets the txn fees?

MattLM Maybe. Little good if tx fees are low to nonexistent.

peerchemist Yup

Cybnate Yep, called forging. You will need good utility or liquidity to be successful indeed.

peerchemist Isn’t ethereum (and hundreds of clones) basically this? You need to be an app chain to survive, basically.

But then again people expect this same thing will sustain bitcoin after the block subsidy stops.

Cybnate Utility is one, another common way to create demand is to somehow put an incentive to turn those transaction fees into demand for the coins.

selfwithin To create demand you need be listed on major exchange. That is it.

exchange will add new user Every years are more people adope crypto.

Arthur This is the critical issue we see too. Bitcoin will one day be forced to solely rely on transaction fees, except they will have to cover the capital and operating costs of their mining infrastructure. Bitcoin will not be able to compete on cost with proof-of-stake coins.

While it’s a far off problem for Bitcoin, its energy waste will become more of an issue in the near future, as AI demands force countries to eliminate their biggest sources of energy waste. We think there may be increasing demand for proof-of-stake coins soon.

We’re introducing Patchcoin as a competitor to Bitcoin, not Peercoin. As evidenced by giving away 100% of the supply. Cybnate is right that our intentions are friendly.

Cybnate Hmm, when coin has fixed supply and demand comes from forging somehow, the value will go up typically. That will create liquidity and the exchanges will come automatically

Arthur and thank you Sentinelrv for clarifying: we are not associated with the Peercoin team, and will continue to make that clear in our eventual announcement

Cybnate In response to Arthur, that Bitcoin is not sustainable long term is clear, but that is likely to be some time away. You might be right that Bitcoin may not be able to compete for the energy required. However that could also increase the price even further in a free market. Hard to tell. Anyway looking forward to your whitepaper, economic model.

Arthur We’re looking forward to sharing more soon, thank you

peerchemist It’s important that it’s never boring around here :rofl:

selfwithin They have cool logo.

Arthur All we can promise is that 100% of this is going to Peercoin holders, so even if it’s not for everyone, that’s okay. We’re excited to share it.

And we can promise that no government officials or celebrities are going to rugpull anyone on Patchcoin’s release, which hasn’t been the trend in 2025 so far

Cybnate Don’t forget to share what you are going to do with the unclaimed coins :wink:

Arthur Of course. We plan on offering an extended claims period, with the goal of getting the entire Patchcoin supply claimed for free by Peercoin holders. There will be a way to track that in our client wallet. And to prove that there are no developer reserves or secret funds.

If any are left at the end of the claims period, we’ll likely auction them off for a small development fund. But again - we would prefer not reaching that point.

MattLM There will be plenty of unclaimed coins since a good chunk of ppc hasn’t been moved in some time.

Unless it’s a first come first serve with only a fraction of the ppc supply that can claim?

Arthur The specifics we’ll reveal on 22 February or so.

You’re correct that lots of PPC are held in dead exchanges and abandoned accounts, who we wouldn’t want to make claims. The purpose of our claims period will be to get Patchcoin into the hands of the people who are most involved in the Peercoin community.

So if you’re reading this, chances are you’ll be happy once the claim period begins.

backpacker “To claim your coins in this new project, ensure that your Peercoins are stored in a personal wallet (not on an exchange) by block 795,000, approximately 19 February 2025.”

does it include multisig addresses

Jack17 It does sound interesting. Does the ‘Patch’ in Patchcoin mean it is designed to patch Bitcoin fees faults? Does the distribution include flutter wallet coins or QT wallet coins or both?

backpacker flutter wallet is first class non custodial wallet, it cannot be excluded

NPC depends if they have a forked backend

HighLow in short words…Patchcoin is a soft fork of PPC…a PPC with limited supply…ok…thank you…

What are the details of collection? How can I collect my mobile wallet?

Sentinelrv This has always been one of Peercoin’s core arguments, that Bitcoin’s long-term security remains questionable due to the future transition of mining rewards being an inflation subsidy to being solely provided by transaction fees. Many of us don’t believe this transition will be sustainable.

Peercoin, on the other hand, was designed by Sunny King to solve this problem. PoS inflation in Peercoin is continuous, which ensures PoS minters will always have a monetary incentive to continue producing blocks via minting. This is why Peercoin is called the sustainable cryptocoin. It is energy efficient, yes, but the incentive to secure should last its entire lifespan.

And even though Peercoin’s inflation will never end, it is designed to be limited, not severe (only about 2-3% per year, still trending downward).

Bitcoin could also switch to a continuous block reward in order to solve their problem, but then it would become inflationary and their end goal of 21 million coins could not be met.

Even if Bitcoin did switch to a continuous block reward, it would not be able to compete with Peercoin on inflation. Bitcoin would need to produce enough new coins each year to sustain the costs of the entire mining industry. By comparison, Peercoin doesn’t have massive electricity and hardware costs to support due to its reliance on PoS, so annual inflation can afford to be limited.

MattLM Worth pointing out that, currently, Peercoin inflation does not cause dilution for continuous minters, as the minting reward exceeds the supply inflation. Continuous minters are rewarded with an increased share in the network over time.

Arthur This is exactly what we meant in our pre-ANN by “we view Patchcoin and Peercoin as sister cryptocurrencies – with a shared background, values, and purpose, but each having its own unique characteristics.”

Patchcoin and Peercoin will agree on the basic problem: Bitcoin will become unsustainable in the long term because of what you pointed out. And that proof-of-stake is a better solution.

The “unique characteristics” part of our message is where Patchcoin will differ.

We’ve noticed that everyone here agrees that a minor 2-3% PPC inflation is ideal, and that’s great. The widespread agreement is also because everyone who disagrees isn’t here.

Patchcoin is going to give Peercoin holders an opportunity to have it both ways: one cryptocurrency that has inflation (and more ambitious future utility plans), and one cryptocurrency that has a fixed supply. Two for one, at no extra cost to Peercoin holders.

Patchcoin will bring attention to Peercoin’s technology to an entirely new group of users who - like our development team - strongly prefer fixed-supply cryptocurrencies that function more like digital gold.

peerchemist Basically, the ancient crypto-currency or crypto-asset debate.

MattLM I appreciate your perspective Arthur though gold isn’t fixed in circulating supply as it’s continuously mined.

peerchemist Fixed supply something can not be a currency. It can be a an asset, a pet rock.

Arthur Anything can be a currency. But agreed that fixed-supply functions better as a scarce store of value, rather than a reliable medium of exchange.

I don’t expect to see Patchcoin credit cards any time soon because the price will be volatile, just like Bitcoin.

Arthur I think Bitcoin isn’t any different. A portion of the supply is available to users, and a portion remains to be mined. Just like gold on our planet.

The other nice thing about a free claim is that you’re free to sell at any time. For those who prefer Peercoin’s inflation model, you’ll be able to sell Patchcoin and buy more Peercoin.

MattLM Gold supply should continue to increase much beyond bitcoin which has a hard cap (under current rules). I imagine there is still a lot of gold to mine.

peerchemist when you speak of peercoin technology, do you mean something other than the PoS consensus? For example the in-house Flutter Wallet or ROAST and the upcoming APO soft-fork?

I wonder how will patchcoin rules look like? Is it a 1:1 clone? Does it have some tech features not present in peercoin?

Does it plan to track the peercoin tech advancement in the long term, or try to come up with it’s own?

What are the long term plans anyway?
