⚡ Neptune Core v0.19.3 is out!
Another step toward letting nodes join the network without downloading every block:
• Nodes can now share archival mutator set data, verified against the chain before it's accepted
• Options to refuse incoming connections or connect only to listed peers
• Earlier rejection of bad-standing peers and tighter block-serving limits
• Mempool fix and updated docs, including an explainer on succinctness

⚡ Neptune Core v0.19.2 is out!
Two days after v0.19.1, the P2P work continues, with a focus on protecting nodes from overload:
• Invalid blocks dropped early, before costly proof verification
• Rate limits on blocks served to peers
• More reliable connections for nodes behind routers and firewalls
• Mempool and mining fixes

So, $NPT is getting interesting.
Imagine a blockchain that doesn't need to carry its entire history around forever.
That's what Neptune Cash is working towards with succinctness, now nearing its final stages.
Think of it like replacing a library of records with a compact mathematical proof.
✅ Major scalability upgrade approaching
✅ Mining infrastructure improving
✅ New Chrome wallet released
✅ Privacy-first, quantum-resistant design
@NeptuneCash is tackling some of blockchain's biggest technical challenges.
Still early. Still risks. But the technology deserves attention.
🛠️ Dev update: succinctness in its final stages
• Succinctness: set to ship as a soft fork that keeps today's throughput limit. Capacity increases follow later by hard fork, preserving the recursive proof chain.
• Security: research and review continue.
• Mining: Lentern.io builds block proposals in as little as 39 seconds, NPTmining.com finds nearly 15% of blocks, and both major pools pay out time-locked coins correctly.
• Wallets: a new community Chrome extension wallet is out.
Coming this week: the succinctness pull request, with an explainer blog post in the works.

If you’re curious about post-quantum projects, I’ve put together the full lineup of post-quantum blockchains. Not financial advice.

Exactly! A few additional catalysts:
1) Ethereum's evolving roadmap increasingly emphasizes privacy, ZK proofs, and post-quantum security. A testament to the forward-thinking design behind Neptune's architecture and technology.
2) Advances in AI-driven cryptanalysis and quantum computing are increasing the need for existing chains to strengthen their cryptographic foundations. Transitioning to quantum-resistant cryptography is no simple feat.
We are early. 🔐 neptune-cash:native

$NPT | Neptune Cash — The Bigger Picture Is Taking Shape.
@NeptuneCash is quietly maturing into something very interesting.
A working, privacy-first blockchain built with quantum-resistant cryptography, zero-knowledge proofs and serious long-term ambitions.
This isn't a narrative I believe will simply come and go. Privacy, security and quantum resistance could become some of the most important foundations of Web3.
Development is progressing, the technology is taking shape, and I believe the market is yet to appreciate the potential.
That's why I've positioned my buy orders on SafeTrade.
I'm looking beyond the next pump. I'm looking at what $NPT could become. 🦁

In the past 4 days...
Google: We've shown that magic state cultivation works on Google Quantum AI hardware.
Quantinuum: We've broken the error-correction world record by 10x.
NVIDIA: We've run a record breaking fault-tolerant quantum computing simulation.
Let's get to work.

🦁 NEPTUNE CASH neptune-cash:native — A PRIVACY LAYER 1 THAT DESERVES MORE ATTENTION
Every cycle, thousands of crypto projects compete for attention. Most are fighting over the same narratives.
But occasionally, you come across something that makes you want to dig a little deeper.
For me, that's @NeptuneCash @CodewordNeptune .
I've been researching neptune-cash:native, and the deeper I go, the more interesting the underlying technology becomes.
Here's why I think it's worth putting on your radar.
1. NOT JUST ANOTHER PRIVACY COIN
Neptune Cash is an independent, open-source Layer 1 blockchain built from scratch.
It combines several technologies that could become increasingly important over the coming years:
• Privacy by default
• Post-quantum cryptography
• zk-STARK zero-knowledge proofs
• Proof-of-Work security
• Programmable transactions
• A roadmap towards blockchain succinctness
The ambition is to create private, programmable digital money without sacrificing security or decentralisation.
And importantly, this isn't just a whitepaper. Mainnet launched in February 2025, and development continues.
2. THE PEOPLE BEHIND IT
Co-founder @aszepieniec Alan Szepieniec is a cryptography researcher with an extensive record of published academic work.
In 2020, he co-authored Transparent SNARKs from DARK Compilers alongside Benedikt Bünz and Ben Fisch.
That research forms part of a broader field of cryptographic innovation explored by researchers associated with Microsoft Research and a16z.
To be clear, this does NOT mean Microsoft or a16z have partnered with Neptune Cash.
It does, however, demonstrate the calibre of research associated with one of Neptune's founders.
That's a meaningful distinction in an industry where technical claims are often much bigger than the technology behind them.
Research:
eprint.iacr.org/search?autho…
3. TOKENOMICS — AN INTERESTING SUPPLY STRUCTURE
NPT has a maximum supply of 42 million coins.
• 42M maximum supply
• 1.98% initial premine
• Proof-of-Work issuance
• Approximately three-year halving intervals
• 50% of mining subsidies immediately liquid
• 50% time-locked for three years
That last point is particularly interesting.
Half of each new mining subsidy cannot immediately enter the liquid market.
This potentially reduces short-term miner selling pressure, although those coins eventually unlock and become available.
Of course, limited circulating supply doesn't guarantee price appreciation. Liquidity and demand matter just as much.
4. THE TECHNOLOGY
Neptune uses zk-STARKs to prove that transactions are valid without publicly revealing the underlying financial information.
Its Triton VM provides the cryptographic foundation for programmable transactions.
The network also separates mining into transaction proof upgrading, block composing and proof-of-work guessing.
One of the most ambitious developments is succinctness, which aims to allow participants to verify blockchain history using dramatically less information.
Full succinctness is not yet deployed, and broader smart-contract functionality is still developing.
If successfully delivered, these capabilities could make Neptune a very interesting competitor in the privacy-focused blockchain sector.
5. WHY I'M ACCUMALATING
Financial privacy is becoming an increasingly important conversation.
At the same time, quantum computing is raising questions about the long-term security of today's cryptographic systems.
Neptune is attempting to address both while building infrastructure for programmable financial applications.
That's an ambitious combination.
But let's be clear: this is an early-stage, high-risk project.
The network has previously required important security fixes, and wider adoption, developer activity, liquidity and delivery of its roadmap still need to be demonstrated.
I'm not suggesting any of this guarantees success.
I'm highlighting a project with serious technical ambitions and a research background that I believe deserves more attention.
6. HOW TO GET neptune-cash:native
Access to native Neptune Cash remains relatively limited.
The routes currently worth exploring are:
• SafeTrade: safetrade.com — NPT/USDT market
• Mining: Participate in the network's proof-of-work mining process
• Approved community escrow: Private OTC transactions using a verified, community-approved escrow arrangement
For escrow transactions, independently verify the authorised service or contact through Neptune's official community before sending funds.
⚠️ Be particularly careful not to confuse native neptune-cash:native with XNT (Neptune Privacy) or wrapped neptune-cash:native on Base. These are not interchangeable native assets.

I've been around crypto long enough to know that great technology doesn't always result in a successful investment.
But I also believe some of the most interesting opportunities are found before the wider market starts paying attention.
Neptune Cash is one I'm researching closely.
The question now is whether the team can turn that technical foundation into real adoption.
Has anyone else been researching neptune-cash:native? I'd be interested to hear your thoughts.

Strong disagree. Lattices have juicy mathematical structure, ripe for AI to attack. And the succinct versions based on module SIS are too new -- only around since 2012.
I recommend waiting another 3-5 years for AI to kick the tires, before entrusting serious $ with it.
DYOR; stay safe.

Sorry @QuantusNetwork, quantus:native is a clean narrative, but @NeptuneCash $NPT already did the harder version of this.
Neptune has been on mainnet since Feb 2025 with zk-STARKs at L1, mutator sets for private transfers that stay succinct, and private smart contracts.
Post-quantum from day one, hash-based, no migration later.
QTC launched Sept 2026 on ML-DSA, no contracts on-chain. Quantum-secure money is the pitch. Neptune shipped the privacy, the proofs, and the fairer issuance first.

Dear @Trezor !
Please support native $NPT @NeptuneCash!
Privacy + post-quantum security matter. NPT aligns with @VitalikButerin’s vision for hash-based cryptography and long-term security in an AI-powered future.

I don't recommend anyone scramble to move their funds to new wallets today. But we should take the risks to cryptography from AI-accelerated math seriously, and minimize our exposure to not just quantum-vulnerable cryptography, but also potentially AI-vulnerable cryptography.
The core new area of risk from this viewpoint is, unfortunately, ML-DSA / FHE / lattices.
(and it's also another reason, along with quantum, why ECDSA might fall even faster than expected, hence the "fresh address" recommendation)
So far most people have been in the mode of thinking "elliptic curves broken, hashes safe, lattices safe". But there is a good chance that the concrete security of lattices will take serious hits from the next two years of AI math.
The basic threat model is: factoring is something that naively takes 2^(n/2) time, but over decades smart people have found and optimized number field sieves, and degraded that to 2^O(n^(1/3)), which is why RSA keys and signatures need to be ~400 bytes (and not 64 bytes). What if there are skeletons in the closet like that, both for elliptic curves and lattices, that we are simply not smart enough to discover - but bots soon will be?
This is a major part of the reason why for the past year ethereum's lean roadmap has been going in the "hash-only" direction: no lattices, no ML-DSA, no Falcon, no lattice-based commitments inside ZK proofs, etc. Signatures in lean ethereum are all hash-based, either WOTS or SPHINCS-.
For signatures and proofs, we already know how to go hash-only. The bigger challenge is for *public-key encryption* - and this goes far beyond blockchains. Secure communication, anonymizing protocols, lots of things need public-key encryption.
And unfortunately there are long-standing mathematical theorems showing why public-key encryption cannot be done with hashes alone. You have to have some kind of trapdoor object that has at least one form of usable "structure" - either group theory (incl. isogenies) or lattices or code-based or potentially in the future even more newfangled and spooky things (local mixing?). But for anything that has structure, you should assume that AI will make at least some progress in breaking that structure. Here, one reasonable inference is that if you want to make something plausibly long-term secure, multiply the key sizes by 10.
To me that's a very plausible world and something not at all extreme to predict. If AI will bring us 50 years of math in 2 years, then that 50 years of math may very plausibly include a "naive factoring -> GNFS" level of improvement to our ability to break lattices. In that world, lattices will still exist, but they will have to be significantly bigger to guarantee the same level of safety.
And at those new larger sizes, hash-based constructions will beat lattice-based constructions on concrete efficiency in every use case where hash-based constructions are possible at all.
Theoretically, of course it's possible that hashes are broken too (eg. P = NP would imply that). But I think P = NP is very unlikely. And intuitively, it's much more likely that a mathematical object has exactly no exploitable structure (like hashes are intended to), than that a mathematical object has exactly ~3 forms of exploitable structure (for elliptic curves: associativity, Schoof, pairings) and not some secret fourth form of structure we have not yet discovered that greatly degrades its security (for elliptic curves, ECDLP and pairing security). Similar for LWE, SVP, RLWE and the zoo of lattice problems.
For this reason, we do not yet see any reason to worry and start padding the byte size of hashes (if we start to worry more, we would pad the round count first before doing anything to the byte size).
Concrete TLDR, my own personal views:
* Hash-based > lattice-based, in those situations where hash-based is possible at all
* For anything lattice-based, be much more paranoid on param sizes. Remember that blockchains are only a small portion of the cryptography story; this point goes far beyond blockchains and applies to eg. access to websites, secure messaging, Tor / VPNs ...
* For privacy protocols, strongly favor NOT putting encrypted notes onchain. Instead, send them offchain through some third-party mechanism.
* If it's not difficult for you, keeping your funds in addresses which have not yet been used to make a transaction is a good idea. If it's easy for you, do it. **But be careful about migrations; I personally have lost more money in botched migrations than I have lost in all hacks combined**.
* For multisig wallets, doing confirmations offchain is better than onchain, because this way the signatures of signer wallets do not get exposed to the public, so if ECDSA falls to AI much faster than expected, at least the multisig "gracefully degrades" to a 1-of-1 where the 1 is whoever was gathering the signatures - a much better place to be than "anyone can take the money"

It's not like there weren't any warnings:
"Unfortunately, the growth of elliptic curve use has bumped up against the fact of continued progress in the research on quantum computing, which has made it clear that elliptic curve cryptography is not the long term solution many once hoped it would be."

Dev update: Neptune's next phase is taking shape 🛠️
More capacity, a smart contract unlock, and proofs built to scale:
• Scaling: trimming the data each block carries so more fits, targeting 5,000 to 10,000 spent coins per block.
• Smart contracts: a key design blocker is solved. Coinbase transactions will accept inputs, opening the door to standing swap orders.
• Succinctness: proof trees keep the chain's proof efficient as blocks get busier, with proving split to run in parallel.
