While securing a non-fungible token (NFT) might sound like a good idea, doing so comes with cybersecurity risks for buyers. Anyone getting into this alternative investment type should understand the cyberthreats they’re up against. 1. Reentrancy Attack A reentrancy attack exploits a vulnerability to force smart contracts into infinite loops. Since these self-executing agreements execute imperatively — meaning each line of code must finish executing before moving on to the next one — they effectively unquestioningly hand over control when making external calls. If the called contract is malicious, it can make recursive callbacks. Since the caller must pause its…

Blockchain: The Spectrum of Decentralization Blockchain technology has been hailed as the epitome of decentralization, but the truth is far more nuanced. The spectrum of blockchain networks reveals a range of trade-offs between true decentralization and practicality. Public and private blockchains offer distinct features that cater to different needs, raising the question—how important is absolute decentralization in real-world applications? What are Public and Private Blockchains? Public blockchains (such as Bitcoin and Ethereum) are permissionless, open-source networks where anyone can participate as a node, validator, or miner. Democracy is built into the design—consensus mechanisms like proof-of-work (PoW) or proof-of-stake (PoS) allow…

Bitcoin, the world’s first and most prominent cryptocurrency, is designed to be a decentralized and immutable ledger. However, this doesn’t mean the Bitcoin network is immune to changes. One such change, a sometimes contentious and potentially disruptive event, is a network fork. Understanding what a fork is, why it happens, and its potential impact is crucial for anyone involved in the Bitcoin ecosystem, whether you’re a long-term holder, a miner, or simply curious. What is a Bitcoin Fork? In simple terms, a Bitcoin fork is a change to the Bitcoin blockchain’s protocol. Think of the Bitcoin protocol as the rules…

Key Takeaways: Scammers are mailing fake Ledger letters via USPS, urging crypto users to “validate” wallets to steal private keys. Physical phishing tactics mark a shift from online-only attacks, raising new concerns for crypto security. Fake Ledger Live apps are targeting macOS users with trojanized malware designed to steal recovery phrases. A new phishing scam is targeting crypto holders through traditional mail, with scammers impersonating hardware wallet maker Ledger and sending fake letters urging users to “validate” their wallets or risk losing access to funds.BitGo CEO Mike Belshe was among the first to flag the attack, sharing an image of…

Bitcoin dominance, a metric that tracks Bitcoin’s market capitalization as a percentage of the total cryptocurrency market capitalization, has been exhibiting a notable upward trend recently. This resurgence has sparked considerable debate and speculation within the crypto community, raising questions about its potential impact on altcoins and the overall market ecosystem. Understanding the drivers behind this increasing dominance and its potential implications is crucial for investors and participants alike.## Understanding Bitcoin DominanceBitcoin dominance is a simple yet powerful indicator. It essentially tells us what proportion of the total crypto market value is held in Bitcoin. A high dominance percentage suggests…

The Evolution of Data Management For decades, traditional databases have relied on centralized systems, where a single authority controls data access, modification, and security. However, this approach has several limitations—single points of failure, lack of transparency, and vulnerability to censorship or manipulation. Blockchain technology offers a radical shift by introducing decentralization, immutability, and community consensus. Understanding Decentralized Databases Unlike centralized systems, decentralized databases distribute data across a network of nodes rather than storing it in a single location. Each node holds a partial or complete copy of the database, ensuring that no single failure or actor can compromise the entire…

Sotheby’s is selling what it’s calling “one of the most significant offerings of Napoleonic material ever to come to market” on June 25 in Paris. Around 100 lots from the private collection of prominent French antiques collector Pierre-Jean Chalençon will hit the auction block. They span imperial furniture, Old Master paintings, and “deeply personal relics that reflect the inner world of [Napoleon Bonaparte],” Sotheby’s said in a statement.“Echoing Napoleon’s words—‘What a novel my life!’—this collection reads like a vivid historical epic, unfolding across battlefields and boudoirs, ceremonial halls, and intimate chambers, alternating a chronicle of power, politics, and pageantry, to…

The decentralized oracle network Chainlink (LINK) continues to dominate crypto’s real-world asset (RWA) sector in terms of development activity, according to the analytics firm Santiment. Santiment notes in a new post on the social media platform X that Chainlink registered 532.43 notable GitHub events in the past 30 days. The figure far exceeds the second-ranked RWA project, the layer-1 blockchain Avalanche (AVAX), which clocked 290.87 GitHub events. The peer-to-peer payments project Stellar (XLM) was third, with 240.7. Chainlink has occupied the top spot on Santiment’s list all year, often clocking multiple times the number of GitHub events as the second-ranked…
