Thanks! It will be very helpful.

Here is the block explorer, please let me know if you have any issues or suggestions: https://i0coin.network/

Regarding what I'm working on, it will be a hard fork, currently targeted at block 4,704,000 (might change).

In short, the big changes will be moving to BLAKE3 across all hashing layers, AuxPoW/merged mining dropped, header expanded to carry UTXO commitment (fast sync without trust), history root (O(log n) header proofs for light clients), and filter root (BIP-157/158 style private SPV).

Mining retargeted with ASERT (90s blocks). Halvings replaced by 5 I0C perpetual emission.

This will be a complete modernization of the oldest altcoin still running (2011).

Same chain, new rules.

Are you getting rid of merged mining? That would be a big change if so and does I0COIN not kinda depend on the merged mining for security especially with all this quantum stuff being talked about?

Will the name and logo stay the same although the name can be confusing with the zero instead of letter o as someone already mentioned? I think iocoin with a letter o is already taken and of course zerocoin is taken also. Nothing wrong with the name but can be hard for noobs to the coin to find on an exchange not understanding the that the o is a number zero.

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.

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.
