Quantum Resistant Ledger Wallet Review : Secure digital assets for an adversarial future


About Quantum Resistant Ledger

The Quantum Resistant Ledger (QRL) bills itself is a ‘fully quantum resistant blockchain network, using PQ-CRYPTO recommended/IETF standardized cryptography’. The QRL utilizes a hash-based eXtended Merkle Tree Signature Scheme (XMSS) instead of ECDSA, which is reportedly vulnerable to quantum attacks and found in many other blockchain projects. The project claims that the security of its platform is complemented by a suite of applications and a development ecosystem which allows users to ‘easily build blockchain applications on its provably quantum resistant network’.

Foundational Security

Not just against today’s computers, but tomorrow’s quantum-computers as well.

QRL is the first industrial implementation to utilize IETF standardised XMSS; a hash-based, forward secure signature scheme with minimal security assumptions.

An extensible address format ensures we are ready for anything out of NIST. Implementation has been verified with two audits, one by red4sec and another by x41 D-sec.

Developer Friendly

Extensive documentation and an API referencegives the tools to build anything, today, on an industrial grade platform that will survive tomorrow. Some features already available:

  • On-chain messages (80 bytes)
  • Full-featured API

Features under development are:

  • Easy to secure smart-contracts
  • Ephemeral messaging ultilising Dilithiumand Kyber
  • Multisignature wallet capability

User Orientated

A consistent UI throughout the whole product space gives a uniform experience accompanied by a full suite of products with binaries that have 99.9% coverage means anyone has access to:

Quantum Resistant Ledger: The Basics

  1. Quantum Resistant Ledger is a cryptocurrency based on the Python programming language, aimed at combating future attacks by quantum computers.
  2. This cryptocurrency is the brainchild of Peter Waterland who realised that Bitcoin, Ethereum, and other such cryptocurrencies have no protection against future technology.
  3. It claims to be a “future-proof” cryptocurrency which enables transactions and decentralized communication while providing protection against classical as well as quantum computer attacks.

Quantum Resistant Ledger  

  1. Digital signatures used in most cryptocurrencies are based on elliptic curve public-key cryptography. The commonly used signature algorithms like ECDSA, DSA and RSA are vulnerable to attacks by quantum computers.
  2. The fork which would make the common cryptocurrencies of today like Bitcoin and Ethereum resistant to quantum computing attacks would be a major had fork, which is likely to lead to instability and high volatility.
  3. There do exist cryptographic algorithms which are already resistant to these attacks, like hash-based cryptography, code-based cryptography, lattice-based cryptography, etc.
  4. The Quantum Resistant Ledger cryptocurrency uses the hash-based digital signature scheme to combat the anticipated quantum attacks as it has minimal security requirements and is said to be the simplest to implement among all the quantum resistant schemes.
  1. Tezor Wallet

A popular hardware Bitcoin wallet that functions as a USB dongle, Trezor allows users to safely access their cryptocurrency even on insecure computers. It operates on a “Zero Trust” basis using multiple layers of security to minimize any risk of assets being compromised by a third party. The Trezor Wallet is integrated with crypto exchange services such as ShapeShift, Changelly, CoinSwitch, ChangeNow, and AirSwap. Copay and MyEtherWallet compatibility allows Trezor users to take advantage of its superior security. The wallet is available in two models: Trezor One and Trezor Model.


The Ledger Hardware wallet provides access to the world’s leading digital currencies, and supports many others. It features a 3.5-inch color touchscreen and Bluetooth capabilities. Ledger also offers high-level security, a user-friendly interface, and integrations with several exchange services. The companion software Ledger Live is available on all desktop devices. The Ledger Hardware wallet is available in two models: Ledger Nano S / Ledger Blue.

Tips for securely storing your Golem

  • Do your own research. Before sending any coins or private data to a wallet, make sure you have researched the wallet provider to make sure everything is above board. Keep an eye out for scam wallets, such as those using URLs only slightly different to the URLs of legitimate wallet providers, and check out some independent reviews for all the pros and cons.
  • Back it up. Make use of your wallet’s back-up and restore facility so that if something ever goes wrong with your wallet, you’ll be able to recover your funds.
  • Set a strong password. Now is not the time to be lazy when creating a password; take your time to create a strong and uncrackable code.
  • Make use of all available security features. Make the most of all the security features your wallet offers, such as two-factor authentication or multi-signature transactions. It’ll offer increased protection for your funds and greater peace of mind for you.
  • Update your antivirus software. Take care to regularly update the antivirus protection and anti-malware software on any device you will be using to access your wallet.
  • Keep your private keys private. Last but not least, don’t underestimate the importance of your private keys. Store them somewhere safe and don’t share them with anyone else.
