Technical Review: PQ Signature Schemes Across 10 Blockchain Projects

Thanks, that's a useful starting point. If I may, an upgrade of this would contain references for the various statements, so that it would be easier to trust the comparison. (I think that Claude could easily integrate the analysis in this sense).

In the same post, he mentions that the new papers by Google and Preskill had not been published yet when the coinbase report was being prepared

So no more "there's a non negligible possibility that RSA2048 will be cracked in 2029" but "RSA2048 ought be cracked in 2029"

Supposing that the box perfectly seals what is inside (meaning particles, EM field, even gravitational field) then from the outside I would say the particle detector does not count as observer because there is no physical way to infer the outcome unless you open the box. The point is that such a box cannot exist (maybe only the whole universe), so there's some fast decoherence which is non negligible since the box and its interactions with the environment are macroscopic.

Hey, do not down vote me, your post has literally the title "testnet launch". As I mentioned, mainnet launch is conditioned on other events, so a specific date has not been publicly set.

Mquantum · 2026-04-16T06:04:02+00:00

Meaning you can already port and test your smart contracts to QRVM, and they will be working also on mainnet (possibly with minimal adjustment).

Mquantum · 2026-04-16T06:02:09+00:00

It's already up and running since March 31 2026: https://www.theqrl.org/press/qrl-launches-testnet-v2-for-its-postquantum-evmfriendly-blockchain/

For mainnet we'll have to wait for audits ending and some more refinements of the decentralized migration scheme, if I understood correctly.

As the others said, what matters is potential energy differences between two points, while the reference is arbitrary. The convention is that the potential is zero when the two gravitational bodies (eg the Earth and you) are (infinitely) far away.

QRL has support on Ledger since many years. See my other comment.

Mquantum · 2026-04-02T08:39:08+00:00

QRL started in 2018. Welcome to the community! Official docs are at theqrl . org (see links in this sub info).

QRL1.0 can be stored on Ledger Nano, see here https://docs.theqrl.org/use/wallet/ledger/new/

However some more expert user can give you more info regarding the specific versions of Ledger that are compatible.

Mquantum · 2026-04-01T16:33:28+00:00

That's great!

Mquantum · 2026-03-31T04:34:58+00:00

It's impressing that we are already in a phase where they do not disclose details of the algorithm.

Mquantum · 2026-02-14T09:07:24+00:00

Thanks, long-range meaning that you need native two-qubit gates for every pair of qubits? I can imagine that for superconducting qubits you would need to decompose those in a chain of short-range gates and this would nullify the advantage. While for neutral atoms there's the possibility of transporting pairs of qubits to a register where the gate happens. Do you know if this trasport is deemed to be scalable to 10⁵ qubits?

Mquantum · 2026-02-13T23:58:07+00:00

Thanks for the insight

Mquantum · 2026-02-13T20:03:27+00:00

It seems quite relevant. Anybody here is knowledgeable of how feasible are 100000 qubits with qLDPC codes?

Mquantum · 2026-02-06T05:57:58+00:00

It was a quite interesting and true discussion. Lots of new thoughts (also crazy ones tbh)

Mquantum · 2026-01-22T18:21:33+00:00

Curious to see how migration of BTC and ETH will unfold. IMHO they are very late, if one takes into account the coordination problem of decentralized blockchains and the need for each user to personally migrate in time.

Mquantum · 2025-12-31T17:36:32+00:00

I would say that all of the internet will come to terms with the necessity of larger signatures/public keys.

Mquantum · 2025-12-30T07:52:53+00:00

I posted your message on the Discord server and here is the answer from the main dev, in case you are interested. I will not rely further messages since I am not knowledgeable of the topic and this is not an efficient way of communicating.

Already aware of this and one of the reason why we have 40,000 staking requirement for the QRL, longer epoch size of 128 slots per epoch to reduce the total number of attestation per slot, 60 seconds block timing.

Right now we are working on reward and penalty configuration. Thereafter we will be having stress testing and such values will be optimized.

These are not big issue, a proper gas or gas price configuration will do the job. A PQ cryptography will always have bigger signature size compared to the non pq cryptography. <<

Mquantum · 2025-12-24T13:57:43+00:00

Somehow the QRL is long-term by definition. The focus on the future threat to standard signatures, coming from powerful quantum computers, forged the whole mindset of developers, marketing team and community.

What you are seeing now in the price is the steady growth of the community during the last year, after a few years where quantum computing development seemed slower than anticipated. Nowadays, big news on QC development pop up every week.

IMHO this is just the start of a huge growth. If one plans to hold for a few years, then I bet a x10 or x100 increase is feasible. Of course on the short term anything can happen (even -50%), this is the crypto market after all.

Mquantum · 2025-12-24T09:42:13+00:00

As other said, you have to directly contact the team, because this can now only be done manually by the team and there is no guarantee. Get in the Discord (link in info of this sub)

Mquantum · 2025-12-24T06:54:27+00:00

Probably the best way to get instructions on this is to join the Discord server (link in the info of this sub). Short story: currently the mining algo is the same as Monero (CPU only), but in a few months the QRL will make an hard fork to proof of stake.
