[I0C] I0coin - The Best Choice In Digital Currency

[kr105]

On merged mining:

Yes, AuxPoW is removed. The v2 fork switches from SHA-256d to BLAKE3 for all hashing (PoW, Merkle trees, addresses, sighash), which makes merged mining with Bitcoin/Litecoin technically impossible.

The security concern is valid, but merged mining was always a double-edged sword. It gave us hashrate we did not earn, from miners who did not care about the chain. A single pool deciding to drop i0coin from their merge-mine list could wipe out most of our hashrate overnight. That already happened several times on the i0coin life. That is basically fake hashrate.

Post-fork security comes from: ASERT difficulty adjustment (reacts to hashrate changes in hours, not weeks), 90-second blocks (faster confirmation, as always), and perpetual tail emission (5 I0C/block forever, miners always have incentive to mine, no relying on fees alone that today are essentially 0).

On quantum:

Merged mining does not protect against quantum attacks. Quantum resistance is about signature schemes and hash functions, not where the hashrate comes from. BLAKE3 is not quantum-proof either, but neither is SHA-256d. When quantum becomes a real threat, the answer is post-quantum signatures. That is a future fork for every chain, not just us. We are just not there yet.

On name and logo:

Staying the same. i0coin is i0coin: same chain since 2011, same identity, same ticker

The fork modernizes the internals, it does not change who we are. Rebranding would erase 15 years of history and confuse everyone who already knows the coin.

The zero-vs-O thing is part of the identity at this point. Anyone who found us has figured it out. We are not optimizing for exchange search UX at the cost of losing what makes i0coin recognizable.

Will miners have enough incentive to actually keep mining versus the cost of electricity considering the price and liquidity is so low on freiexchange which is our only exchange and even that could delist us or the exchange itself might close overnight like cryptopia?It's okay while the developer is back and understandable people may be very enthusiastic to see development right now but what happens if you disappear again for another decade or more and there is nobody able to step in.Not comparing with what happened to Markm but things happen unfortunately and we can see this after Markm situation where the whole Galactic Mileu and stellar token trading has just stopped and the ironic thing was Markm was always talking about fly by night exchanges disappearing overninght leading to these type situations yet it was his own passing that has led to that particular one.

Is there any plan apart from technical development to get some type of community growth behind the coin so there will be more buyers so miners can sell their mining rewards to incentivise mining and money can be raised for further development because at the end of the day if theres no funding behind something there is no incentive even for a developer to hang around long term and if that happens the coin is certainly going to linger on life support at best for another decade.

I am just trying to be realistic here so we don't end up like ixcoin permanently hovering around the sinkhole and yes it would be a shame to let these old coins die considering the rubbish scams that have been created after them getting hyped everywhere.Not sure if iocoin or ixcoin is the oldest but they have been around the same length of time approximately.Both are actually brilliant coins once you get the wallets synced up and in fact iocoin is as fast as lightning.60 confirmation block time is a bit much on freiexchange though although if you withdraw from there it is pretty quick.

[kr105]

Right now, mining i0coin is not profitable in any meaningful way with the mining reward at 0.00002288 I0C and requiring an ASIC to mine. The tail emission (5 I0C/block, forever) means there is always something to mine, and by using a different algorithm means that GPUs will be back on the game, but whether it is worth the electricity depends entirely on price. I can't fix that with code.

What I can do is make the chain technically sound enough that if the coin gets traction, the foundation is solid. Nobody is going to adopt or list a coin running on a decade-old codebase that predates modern security practices. The v2 fork is about making i0coin worth taking seriously again.

Getting listed anywhere requires either paying listing fees (which I'm not doing) or having enough volume/community demand that exchanges see value in listing us. That is a chicken-and-egg problem.

I don't have a marketing plan or a treasury. I'm one developer working on this because I think it is worth doing. That is how these old coins survive: one or two stubborn people who keep the lights on. If it wasn't for MarkM still hosting a node until today, I would never have been able to download and sync the full chain and the situation would probably be much different today.

Community growth that depends on one person hyping things up dies the moment that the person stops. What lasts is having clean, modern code that other developers can actually read and contribute to, a spec that is fully documented, and a chain that just works. The v2 fork, the spec, the code, will be all on GitHub. Anyone can run a node, anyone can review the code, anyone can build on it. That is the invitation. What the community does with it is up to the community, as always.

Can this not be done using a soft fork?Surely a hard fork causes a chain split?So what happens if I am using the original version from the beginning and never updated and continue past all these blocks after the hard fork?I am on a split chain right but the actual original one right?

  Bitcoin had a hard fork that resulted in bitcoin cash/bitcoin gold/bitcoinsv etc so surely I am the original iocoin (like people still on the main original bitcoin/btc chain) so then and all coins after the hard forks i0coin has are actually different coins and I would be able to collect a same number of each with my private key the same way I could claim bitcoin cash and sv or what am I missing here?

What I mean is everytime you hardfork then you are causing a chain to split and the original chain before any split that continues is the actual original chain.

[kr105]

A hard fork means old nodes reject new blocks, yes. If you never update, your node stops at the last pre-fork block. But unlike BTC/BCH where both sides had miners and users, there is nobody really mining i0coin right now to sustain two chains. The old chain would just stop.

A soft fork is not possible here. New header format, new tx format, BLAKE3, new script engine. That can't be made backwards compatible.

Your private keys work on both sides, same as any hard fork. Replay protection is built in (different sighash, fork ID). But if nobody mines the old chain, there is no "other chain" to spend on.

The goal is upgrading the only chain that exists, not splitting it.

I think the developer knows what they are doing cornhodlr as they founded I0coin so know what is best for it. If you have any programming skills or know how to counter quantum attack vectors then maybe you can let us all know here but in the meantime here is an interesting post I read about this earlier.  https://pbs.twimg.com/media/HEtKFFfbQAAJsq3.jpg  https://quantumai.google/static/site-assets/downloads/cryptocurrency-whitepaper.pdf

The day Michael Saylor posts an AI slop video about STRC, Google drops a paper showing they're closer than anyone expected to cracking the encryption that protects Bitcoin and many other blockchain networks. Their quantum computing team figured out how to do it with 20x fewer resources than previous estimates. Here's the breakdown:

> Google compiled quantum circuits that can solve the math problem (ECDLP-256) protecting Bitcoin wallets, Ethereum, and most major blockchains

> A quantum computer with fewer than 500,000 physical qubits could run the attack in minutes. Previous estimates required millions.

> Google's own quantum processors are already approaching the hardware capabilities needed to make this work

> They coordinated with the U.S. government before publishing and used zero-knowledge proofs so third parties can verify the results without getting a step-by-step attack playbook

> Every blockchain that uses elliptic curve cryptography is affected, which includes Bitcoin, Ethereum, and most others

> The fix exists: post-quantum cryptography (PQC), encryption designed to resist quantum attacks. Google has been working on it since 2016.

> Google is recommending crypto users stop reusing wallet addresses immediately, since reused addresses expose more information to potential attackers

> Coinbase, the Ethereum Foundation, and Stanford's blockchain research institute are already working with Google on the transition

> Google set 2029 as their target date for full migration to quantum-safe encryption

> Abandoned wallets with no one to update them remain an unsolved problem

Post-Quantum Cryptography (PQC).

The expected emergence of cryptographically relevant quantum computers (CRQCs) will represent
a singular discontinuity in the history of digital security, with wide ranging impacts. This whitepaper
seeks to elucidate specific implications that the capabilities of developing quantum architectures have
on blockchain vulnerabilities and potential mitigation strategies. First, we provide new resource
estimates for breaking the 256-bit Elliptic Curve Discrete Logarithm Problem over the secp256k1
curve, the core of modern blockchain cryptography. We demonstrate that Shor’s algorithm for this
problem can execute with either ≤ 1200 logical qubits and ≤ 90 million Toffoli gates or ≤ 1450
logical qubits and ≤ 70 million Toffoli gates. In the interest of responsible disclosure, we use a zero-
knowledge proof to validate these results without disclosing attack vectors. On superconducting
architectures with 10−3 physical error rates and planar connectivity, those circuits can execute in
minutes using fewer than half a million physical qubits. We introduce a critical distinction between
“fast-clock” (such as superconducting and photonic) and “slow-clock” (such as neutral atom and ion
trap) architectures. Our analysis reveals that the first fast-clock CRQCs would enable “on-spend”
attacks on public mempool transactions of some cryptocurrencies. We survey major cryptocurrency
vulnerabilities through this lens, identifying systemic risks associated with advanced features in
some blockchains such as smart contracts, Proof-of-Stake consensus, and Data Availability Sampling
mechanism, as well as the enduring concern of “abandoned” assets. We argue that technical solutions
would benefit from accompanying public policy and discuss various frameworks of “digital salvage” to
regulate the recovery or destruction of dormant assets while preventing adversarial seizure. We also
discuss implications for other digital assets and tokenization as well as challenges and successful
examples of the ongoing transition to Post-Quantum Cryptography (PQC). Finally, we urge all
vulnerable cryptocurrency communities to join the migration to PQC without delay.

As far as my research goes, we are the 4th altcoin?

- Bitcoin: January 3rd, 2009
- Namecoin: April 18th, 2011
- Devcoin: July 22nd, 2011
- IXCoin: August 10th, 2011
- I0coin: August 15th, 2011
- Solidcoin: August 21st, 2011
- Liquidcoin: September 8th, 2011
- Litecoin: October 19th, 2011

Is anyone aware of any other altcoin between i0coin and bitcoin?

Nope theres nothing else in between I0Coin and Bitcoin. FairBrix was october and that's the only other one I can remember from 2011 and Litecoin was spawned from that. Namecoin was spawned from the BitDNS idea and Devcoin was for some writers incentive. IXCoin was probably the first pure altcoin developed as simply a currency for transactions with faster blocktimes and different mining reward etc but had a premine issue and I0Coin then came along to address that premine issue. Will you be adding any other new privacy features to I0Coin?

[kr105]

Will you be adding any other new privacy features to I0Coin?

yeah kind of, i'm adding compact block filters so light wallets can check for their transactions without revealing their addresses to the server. also dandelion++ for the network layer so transactions bounce through random nodes before broadcasting, making it much harder to link a tx to an IP.

This is practical and functional and a more complex type of privacy that most other coins have. Anyone really who wants to go full tin foil hat mode could also use tor or a vpn probably with their wallet if they know how to do that too  .

 Would mimble wimble extension Blocks work with I0coin?

[kr105]

No, that is way outside the scope of the current changes. But who knows, maybe we can implement it later on like LTC. I think that private transactions on i0coin should be a good fit for a future L2.

Hopefully, you're not planning to develop a Solana version like your Catcoin has I think, or as many other OG coins planning right now - whether with or without a bridge, where the original developer takes a percentage of the fees and old projects are distorted to enrich themselves. Unfortunately, this seems to be a common trend these days for ripping people off.

Hello, what is the official link for wallet or do we wait for a new wallet release?

This Special Drawing Right and I0Coin convertor is up to date with exchange rates from April 4, 2026.
https://coinmill.com/SDR_XIC.html

Why is I0coin listed on coinmill as XIC?

[cornhodlr]

Hello, what is the official link for wallet or do we wait for a new wallet release?

You can go to https://izerocoin.org and download the current wallet from there.Once you do this and start up wallet then go to https://drive.google.com/file/d/11-D1r5s8267YmOT1VaObrcmVoV8d_JAn/view?usp=sharing and download the blockchain.

Once you have the blockchain downloaded then type  %appdata%  into your search bar on your pc and go into roaming file where you have your iocoin executable files and replace the blockchain folder and anything else with what you have in the downloaded blockchain file and restart your wallet and it should be up to date.

Looks like iocoin is no longer listed on coinmarketcap either.

[wiked1]

Why is I0coin listed on coinmill as XIC?

It has been like that for many years now because they probably used that ticker since it was listed there. Maybe they confused it with another coin but I0C is the correct ticker with a zero between the I and the C

I was watching a video about how Ai will be making the majority of transactions on the internet in a few years and will need digital currencies that are able to do micro transactions many thousands per second or something.Any idea if i0coin would be capable of this?

Well it's definitely a better contender than many coins because micro transactions are impossible on bitcoin these days with the fees alone.
