NEAR Protocol becomes first major blockchain with post-quantum signing support onto mainnet, using the 2.13 upgrade and NIST-approved ML-DSA. That is a real cryptographic milestone, and one the rest of the industry will not be able to ignore for long.
- 2.13 upgrade: post-quantum signing is live on NEAR mainnet
- Algorithm: FIPS-204, also known as ML-DSA
- NEAR’s claim: among the first layer-1 blockchains to ship this on mainnet
- Another change: dynamic resharding also shipped in 2.13
The main point is simple: NEAR says builders can now rotate account keys to ML-DSA using NEAR CLI, which means the network can use a post-quantum signature scheme in production. That matters because blockchains live and die by signatures. If the signing layer is broken, ownership becomes a joke.
There is one claim worth treating carefully: “first major blockchain.” That sounds great in a headline, but without a shared definition of “major” and a clear comparison set, it is hard to verify cleanly. The safer reading is that NEAR is, by its own framing, one of the first layer-1 chains to bring a NIST-approved post-quantum signature scheme live on mainnet.
Precision matters here. Crypto loves to toss around words like first, safest, and most scalable as if they come free with every token launch. They do not.
Post-quantum cryptography is built to resist attacks from future quantum computers. The immediate worry is not some sci-fi apocalypse. It is that powerful quantum machines could eventually break the public-key cryptography that protects digital assets and identity. In plain English, if the signing scheme fails, an attacker could forge signatures and impersonate owners.
NEAR’s implementation centers on FIPS-204, better known as ML-DSA. That is a NIST-approved digital signature standard, so this is not just “quantum-safe” marketing fluff with a shiny logo slapped on top. It is a standards-based approach built for a threat model cryptographers have warned about for years.
According to NIST, organizations should start migrating now, not after quantum computers become practical enough to turn legacy cryptography into museum material. NIST also finalized its post-quantum standards in 2024, including FIPS 204 for ML-DSA. Translation: this is not a niche academic curiosity anymore. It is the direction the industry is supposed to be heading.
NEAR says its account design gives it an edge. The network uses human-readable account IDs and rotatable access keys, instead of forcing users to stay tied to one fixed keypair attached to an address forever. That means builders can swap older keys for post-quantum ones through standard tooling, rather than trying to bolt a new cryptographic engine onto a frozen structure.
That does not make migration easy, of course. It just makes it less ugly.
By contrast, older blockchain designs can make cryptographic upgrades painful because funds, wallets, address formats, and user habits are all tied tightly to existing signature schemes. Bitcoin and Ethereum do not suffer from the exact same architecture, but the broader point stands: when you change the math that secures ownership, migration gets messy fast. And messy migrations are where otherwise elegant systems start tripping over their own shoelaces.
NEAR also bundled another meaningful upgrade into 2.13: dynamic resharding. Sharding is a scaling method that splits network work across smaller chunks called shards. Dynamic resharding means those shards can split automatically when they get too full, which helps the network adjust capacity without constant manual intervention.
That is separate from the post-quantum move, but the pairing makes sense. If you want a chain to be taken seriously as long-term infrastructure, it needs to handle both scaling pressure and cryptographic change without turning every upgrade into a political knife fight.
Preparing for the Future: Strategies and Insights and Post-quantum Signing and Dynamic Resharding Now Live on NEAR’s release leans into the “agent economy” pitch, arguing that future software agents will need fast, scalable, quantum-resistant infrastructure. It also cites a projection that agentic commerce could reach $5 trillion globally by 2030. Fine as a vision statement. Not fine as a guarantee. Forecasts are not gravity.
The devil’s advocate view is worth saying out loud: post-quantum support is important, but it is not magic. New cryptographic schemes can bring larger signatures, slower verification, compatibility headaches, wallet support delays, and a heavier audit burden. A chain can be more resilient without being invincible. Anyone claiming otherwise is selling snake oil with better typography.
Still, the move is sensible. NIST has been clear that migration should start now, and NEAR is one of the few major networks putting that warning into production rather than leaving it in a whitepaper drawer. If the implementation holds up in the real world, that is a serious technical win.
What does “post-quantum key support” mean?
It means the network can use signing keys based on cryptography designed to resist future quantum attacks. On NEAR, the supported scheme is ML-DSA, a NIST-approved standard.
Why does NIST approval matter?
Because it gives builders a real standard to work from. This is not a random crypto experiment. It is a vetted algorithm that wallets, developers, and infrastructure providers can align around.
Is NEAR really the first major blockchain to do this?
That claim is not fully verified by the available materials. NEAR’s own wording is softer and more defensible: it says the chain is among the first layer-1 blockchains to bring a NIST-approved post-quantum signing scheme live on mainnet.
Does this make NEAR quantum-proof?
No. It makes NEAR more resistant to one major future threat, but it does not eliminate all cryptographic risk or remove the need for future upgrades.
Why should everyday users care?
Because cryptography is the bedrock of self-custody. If the signing layer is weak, ownership is weak. Any upgrade that improves long-term key security is worth paying attention to, even if it still needs ecosystem support to become widely usable.
What else shipped in NEAR 2.13?
Dynamic resharding. That is a scalability upgrade that lets the network split shards automatically as demand grows, reducing the need for disruptive manual capacity changes.
Securing Electronic Information Against Quantum Threats NEAR’s broader message is clear: it wants to be seen as infrastructure built for the next decade, not just the next market cycle. That is a serious pitch, and unlike a lot of crypto theater, this one is backed by an actual standards-based cryptographic upgrade.
What happens next is the part that matters most. Wallet support, validator adoption, developer tooling, and clean migration paths will decide whether this becomes a real advantage or just a neat technical brag. In crypto, shipping the feature is only half the battle. Making it usable is the part that separates engineering from brochureware.
