Quantum Resistant Ledger(QRL）is a blockchain network which is designed to resist quantum attacks. The founder of QRL, Peter Waterland is one of the earliest group of people who have worryies about the safty of Bitcoin, Etherreum and other blockchain network which use ECDSA or similar algorithums.

With the developement of the quantum computing technologies, the encryption algorithums of these cryptocurrencies will have no effect someday in the future for sure.

QRL figured out a way to slove this problem, it uses a hash-based eXtended Merkle Tree Signature Scheme (XMSS) to encrypt the message. To make a long story short, QRL utilitize the cryptographic method with minimum security requreiment that rely only upon on the collision resistance of cryptographic hash function. the hash-based digital signature scheme is generated from such function. Such signartue is called one time signatures(OTS), which could only be safely used for one time in encrypt the message, so for each address QRL use many OTS which is generated by a binary hash tree, also know as Merkle Tree.

QRL is programmed with python and The total amount of QRL token is 105,000,000. Now the QRL ranked No. 62 in miningpoolstatus.stream. It also allows developers to easily build applications on its platform.
