Key Takeaways Neither Bitcoin nor Ethereum is quantum resistant today. Both rely on ECDSA over secp256k1, the signature scheme a sufficiently powerful quantum computer could break using Shor's algori

Key takeaways Harvest now, decrypt later is already underway. Attackers do not need a quantum computer today; they can collect exposed blockchain public keys now and wait until future quantum hardwar

Q-Day is the moment a quantum computer becomes powerful enough to break the public-key cryptography used across modern digital systems. For cryptocurrency, that means something very specific: a future

Where Is the ABI? Also, Why Is My Cell Dead? A notes app should not send you into an identity crisis. You type something. You click save. Somewhere, some database politely updates itself. If you come

Shor’s algorithm is one of the main reasons quantum computing is treated as a serious long-term threat to modern cryptography. Most public-key cryptography relies on a simple asymmetry: some mathemati

For years, the need to protect cryptocurrency from quantum attack felt like a distant problem. Today, that timeline is shrinking fast. In 2026, Google Quantum AI researchers published a whitepaper wit

Fault-tolerant quantum computing represents a long-term security challenge for major blockchains. Most legacy networks still rely on elliptic-curve cryptography, including ECDSA, EdDSA, or related sig

Key Takeaways Quantum computing threatens the public-key cryptography that most blockchains currently rely on for security. The real blockchain security problem is not only quantum resistance, but cr

As the field of quantum computing rapidly advances, concerns are growing about the potential impact of these powerful machines on the security of blockchain networks. Quantum computers, with their abi

For nearly two decades, Bitcoin’s security has rested on a simple mathematical assumption: that reverse-engineering a private key from a publicly visible public key is practically impossible. This fou

CKB, the Common Knowledge Base, is the Layer 1 blockchain of Nervos Network. Built on a secure Proof-of-Work consensus and designed with flexibility in mind, it provides developers with a foundation f

One of the defining features of CKB (the Common Knowledge Base) is the NervosDAO, a built-in staking mechanism that lets CKByte (also referred to as CKB) holders earn passive rewards by locking their

Anyone with genuine skin in the game who has tried to understand Bitcoin and its broader significance intimately knows what it's like to fall victim to the Dunning-Kruger effect. After the first dozen

The realization that Bitcoin would require additional scaling was made years before the network would struggle with anything resembling a congestion issue. In 2010, less than a year after Bitcoin went

As one of his first forays into crypto, Twitter's founder Jack Dorsey sought to build TBD—a new identity and trust layer for the Internet—intended to run exclusively on peer-to-peer rails, integrated

The rise in popularity of ordinals, inscriptions, and BRC-20 tokens over the last two years has made it abundantly clear that crypto users want tokenized assets on Bitcoin. Ethereum's smart contract e

Every four years, typically in the six months preceding the halving, the debate around the sustainability of Bitcoin's security model gets reignited. The discussion can be summed up in two opposing ar

One strand of thinking that has become popular in crypto land recently is that the only way for blockchains to solve the Scalability Trilemma—or obtain the trifecta of high security, decentralization,

Normally, when we analyze the emission model of a coin such as CKB, we usually only consider the theoretical total number of coins issued over time, i.e., the emission curve. However, this does not fu

The unique tokenomics of Nervos have been specially designed to ensure platform sustainability

In the 14 years since the inception of Bitcoin, blockchain development shifted through multiple stages, each reflecting the evolving needs and challenges faced by the industry at the respective times.

Bitcoin’s most important value proposition in the economic sphere is its fixed issuance policy, since it is not subject to any change, and at the same time predictable, as long as we know how much and

Any prospective blockchain developer that has tried building decentralized applications has quickly realized that the current blockchains offer rather inflexible development environments. Building app

How to run a CKB node on a RaspberryPi 400 with Ubuntu desktop 22.04 Running a node on a RaspberryPi can be a fun, efficient way of helping to decentralise the Nervos Network. Old pro's have probably

To understand how Nervos DAO works, you must first know that it works through cycles, and that each of these cycles are 180 epochs. On the Nervos network, each epoch has an estimated time of 4 hours.

This article seeks to be the be-all and end-all resource for the underlying architecture and value proposition of the Nervos network. Nervos is a modular blockchain network built from the ground up to

An essay on time preference and building future-proof blockchains. The remarkable speed of change in the blockchain industry has increasingly been steering the space toward high time preference thinki
