When Bitcoin BTC/USD launched a peer-to-peer (P2P) lending system in 2009 facilitated by its native token, the world was awe-inspired — and suspicious — over the deserves of a decentralized monetary system.
Greater than a decade later, BTC has not solely emerged because the world’s largest cryptocurrency by market capitalization however has additionally spurred the adoption of blockchain know-how throughout a number of industries. It has additionally spawned a variety of functions, akin to decentralized finance (DeFi), that are revolutionizing the best way people transact.
But, with the rise of a brand new breed of quantum computer systems, the dominance of blockchain-powered protocols like that of Bitcoin may very well be challenged within the close to future.

What Is Quantum Computing?
Whereas conventional computer systems use bits to course of and retailer info by switching between 0 and 1, quantum computer systems use qubits that may concurrently exist in each states.
These computer systems could be hundreds of thousands of instances quicker than the most effective supercomputers immediately.
With this type of computing supremacy, malicious entities might exploit some great benefits of quantum computing to launch assaults on protocols like Bitcoin, in an try and steal funds from the hundreds of thousands of cryptocurrency customers that transact by way of the web immediately.
By using storage assaults or transit assaults, dangerous actors might assault susceptible pockets addresses and even goal transactions.
On the identical time, they’re being processed on the blockchain. Storage assaults are seemingly a much bigger chance since it’s depending on how securely tokens are being held by varied customers, whereas transit assaults are past the realm of a present lot of quantum computer systems in existence immediately.
Supremacy Underneath Assault?
At present, Bitcoin and different blockchain protocols aren’t notably vulnerable to quantum computing assaults. That is as a result of quantum computer systems haven’t progressed past 100 qubits by way of processing capability. This limits the opportunity of an assault on a protocol as giant and safe as that of Bitcoin.
However know-how is progressing at a speedy tempo, and quantum computer systems with greater than 1,000,000 qubits might develop into a actuality throughout the subsequent decade.
With that form of computing energy, the Bitcoin community in its present type can be severely compromised by cybercriminals.
Tasks Thwarting Future Quantum Computing Assaults
There are a variety of tasks which might be working to tweak or introduce new architectures that will make protocols much more safe.
Certainly, blockchain know-how is repeatedly evolving as builders and entrepreneurs attempt to innovate.
Shifting away from elliptic curve cryptography (ECC), which focuses on a set of private and non-private keys to encrypt information, will likely be one of the vital fast duties at hand for crypto builders.
Recognizing the necessity for extra strong and attack-proof options, a variety of tasks are exploring alternate cryptographic strategies to safe the following era of Bitcoin and different protocols.
Some notable examples of quantum-resistant applied sciences embody:
- The block-lattice technique as adopted by the QAN Platform
- Directed acyclic graph (DAG) know-how as seen within the Iota blockchain
- And quantum key distribution (QKD), developed by Toshiba TOSYY and JPMorgan Chase & Co. JPM
Every of those strategies has adopted completely different approaches to make sure that their respective networks can resist quantum computing assaults.
However the important thing message stays: the crypto developer group can be clever to arrange for any dangers posed by quantum computing.
