#数字货币市场洞察 This week in December, the crypto space has been buzzing. Five major chains related to $BTC, $ETH, and $XRP all completed upgrades within just 7 days—a rare occurrence in the industry. Ethereum made the biggest move, with the Fusaka hard fork on December 3 directly impacting both the consensus layer and execution layer, its two core components. At the same time, Flare Network was optimizing performance, MultiversX activated Staking V5 (the name alone signals a major upgrade to its staking mechanism), and VeChain launched a brand new mainnet, Hayabusa, while also rolling out an NFT staking feature. By the 7th, Siacoin and Beldex were also busy—one launched its V2 version, and the other activated the Obscura hard fork. These moves cover a wide range of areas—scalability, privacy protection, consensus optimization—basically addressing all the pain points of ecosystem infrastructure. It’s hard to say whether this will drive prices up in the short term, but from a technical perspective, it’s definitely strengthening the foundational layer.
