【以太坊研究员Justin Drake探讨原生Rollups技术或实现无需信任的扩容方案】
1月23日消息，以太坊研究员贾斯廷·德雷克在以太坊研究论坛上发表文章，探讨了一种新的汇聚设计——“原生汇聚”。简而言之，这种设计依赖于以太坊第一层的验证者进行证明，即状态转换函数和验证。这与乐观汇聚（例如乐观、Arbitrum）或零知识汇聚（例如Starknet、ZKsync）形成对比，后者将计算负担转移到第二层，依赖欺诈或零知识证明系统来生成状态根和证明，再回到主网上。德雷克的提议建议引入“执行”预编译（在以太坊虚拟机中的硬编码函数），用于验证用户交易的以太坊虚拟机状态转换。原生汇聚实现了以下两项突破：不再需要投资和维护昂贵的矿工证明者网络和专用的图形处理单元硬件，因为证明将由第一层验证者处理和执行；不再需要维护复杂的治理结构，包括可信安全委员会来批准合约升级以实现以太坊虚拟机的等效性。这实际上通过继承以太坊第一层的安全性，使原生汇聚变得“无需信任”。 -

00:57Is Bitcoin Losing Its Bullish Momentum?Disclaimer: The analyst who wrote this piece owns shares of MicroStrategy (MSTR) and Semler Scientific (SMLR).MARA Holdings (MARA) has increased its previously announced convertible note offering from $700 million to $850 million.
It has also raised the option for initial purchasers to acquire extra notes to $150 million from $105 million. The offering is expected to close on Nov. 20, and is a private offering directed at qualified institutional buyers.
The notes maturing on March 1, 2030, will not bear regular interest and can be converted into cash, shares of MARA's common stock, or a combination of both at MARA's discretion.
The initial conversion price is approximately $25.91, which is a 42.5% premium over MARA's current stock price, which is currently $18.18.
The proceeds are estimated to be around $833 million, with $199 million being used to repurchase the $212 million of MARA's existing convertible notes for 2026. The rest will be allocated for bitcoin (比特币) acquisition, asset expansion, and general corporate purposes.
MARA is the second largest publicly traded holder of bitcoin, holding 27,562 比特币. This announcement comes after several other bitcoin holders companies, specifically MicroStrategy (MSTR) and Semler Scientific (SMLR), purchased more bitcoin.
MARA's shares are up nearly 2% in pre-market trading after falling nearly 14% on Monday.
