Did you know that more than 90% of IT companies have no preparedness plan for quantum computing security risks? Experts have warned that these threats are likely to become very real in the next 5-10 years. Yet most blockchains today are operating under the false assumption that their transactions are protected.
Researchers have long warned of a “harvest now, decrypt later” scenario. Encrypted data recorded today will be exposed later when quantum computers have reached the cryptographically relevant power. We believe that post quantum cryptography is no longer an optional upgrade…and it’s not just based on some hypothetical threat. It is a matter of survival and time.
…and our question to you is: Are you prepared to face it?
The Silent Assumption No One Questions
Most projects in the blockchain space are operating under the assumption that their cryptography is “future-proof” while their transactions are actually running on ECDSA (Elliptic Curve Digital Signature Algorithm). Since this particular algorithm operates by generating private/public key pairs and relying on the hardness of discrete logarithms, which causes key recovery to be practically impossible with classical computers, most projects assume their cryptography is invincible.
But between Google’s willow chip and IBM’s quantum processors, quantum computers have become very much a reality and challenge to this very assumption. You see, quantum computers rely on Shor’s algorithm which simply factorizes integers and computes discrete logarithms efficiently and can, therefore, solve these very cryptographic problems in a matter of seconds to hours (depending on key size).
This silent assumption of developers that they are secure would have been true if quantum computing had remained just a theory – and quantum security were just a hypothetical concern. But it clearly hasn’t…which is why some forward-looking projects, like ARMchain, are now rethinking the assumption and building systems that are actually quantum ready.
“Harvest Now, Decrypt Later” Is Already Happening
In the blockchain community, we have heard the line “harvest Now, decrypt Later” quite a few times. But what does it actually mean?
Imagine a spy has stolen your locked box today, but he cannot open it just yet. 5 years down the line he invents the key and opens the said box. Some may think that it is useless now. But what if the locked box contains information that can be backtracked to your identity with financial or personal data, and can impact your current day assets or security even after 5 years?
Doesn’t sound fun, does it?
Well, ‘harvest now, decrypt later’ is unfortunately exactly this. Since every transaction, wallet key and smart contract are recorded using a cryptographic algorithm, it can easily be harvested and stored for later. Such a scenario would prove disastrous for individuals who are storing sensitive information on traditional blockchains under the guise that it is unbreakable.
Why “We’ll Upgrade Later” Is a Dangerous Bet
Many blockchains are currently operating under the assumption that if quantum computers do eventually become a threat, they can simply upgrade their cryptography later. Well, if upgrading were that simple and easy, technical debt wouldn’t even have been a problem. The thing is, retrofitting quantum security after the fact is far more complicated than it sounds.
As a developer you will need to:
- Migrate your cryptographic schemes from traditional cryptography to post quantum cryptography algorithms.
- Re-sign every single transaction in a consistent manner so that your ledger remains valid.
- Shift the entire network from classical signatures in the presence of live user funds.
In short, as a blockchain architect, you will need to perform a live cryptographic overhaul, which can easily invalidate transactions, break compatibility, and even lock your users out of their assets. In other words, valuable digital assets could get permanently compromised before you can even implement the upgrade.
This is also why proactive design is crucial, and protocols need to build quantum-resistant systems now. The very belief of these projects is a dangerous illusion which will ultimately cause irreversible damage.
What a Quantum-Aware Blockchain Design Looks Like
A truly quantum-aware blockchain isn’t the one planning to upgrade when “the time comes.” It is a system with resilience baked into its foundational architecture from day 1. This also means rethinking every critical layer of the quantum computing blockchain from how keys are generated to how they’re secured, and from how transactions are signed to how they’re validated.
At the very least, a robust quantum resistant blockchain design needs to include:
- Post quantum cryptography (PQC): Post quantum cryptography refers to cryptographic algorithms designed for the era of quantum computing. This approach needs to be built directly into the wallet signatures so that transactions can remain secure in the long-term.
- Modular Cryptographic Layers: These layers will allow for future upgrades in the protocol without disrupting the existing ledger.
- Protocol-level Flexibility: Having protocol-level flexibility will allow developers to adapt for the future, so cryptographic primitives can evolve, and upgrade seamlessly.
Why ARMchain Stands Out in This Landscape?
This is where ARMchain comes in the picture too. ARMchain is a blockchain built to be quantum ready. The design philosophy of this post quantum cryptography blockchain is what sets the standard of forward security. Instead of relying on the traditional signature schemes, ARMchain has incorporated quantum resistant cryptography with MPC-based wallet infrastructure from the very beginning of its development.
By structuring its transaction layers and consensus around quantum-secure primitives, ARMchain has altogether eliminated the problem of needing to rebuild its foundational security later. As a result, users can transact and build through ARMchain.
But that’s not all, with this post quantum cryptography architecture, you can:
- Trade tokens on the dedicated decentralized exchange of ARMswap for ARMchain with automated, volatility-based fees.
- Participate in DAOs for future direction of ARMchain to vote on proposals and manage community treasuries.
- Build your own dApps – like NFT marketplaces, DEXs, memecoin marketplaces – using the same Solidity code as Ethereum.
- Launch and bridge your stablecoins on a quantum-secure blockchain.
- Earn ARM coins by becoming a node provider in the ARMchain ecosystem.
The goal of this quantum-resistant blockchain is to innovate without the fear of future cryptographic collapse.
This Is About Time, Not Technology
The question now isn’t whether quantum computing will disrupt blockchains or not, but when. The speed with which quantum research is progressing shows we are approaching that deadline quite fast. The industry cannot afford to wait until quantum computers are fully operational and then rethink the security aspect. The transition needs to happen right now.
Proactive projects, like ARMchain, are working ahead of time with quantum-aware systems designed to withstand this inevitable threat. Whether you intend to build or invest, the takeaway is pretty clear: quantum security isn’t a feature upgrade; it is a necessity. You can either become a part of the early adopters and prepare now, or scramble for survival.
