Abstract

SAGA 采用了一种独有的「音乐椅定价」。

原文作者:0x Loki,ABCDE 研究员
SAGA 商业模式的本质是向下游需求方分发区块空间,涉及到的一个关键问题就是如何定价,SAGA 采用了一种独有的「音乐椅定价」进行:
(1)假设初始状态下有 a= 12 个验证者,SAGA 希望从中选择 8 个进行委托验证;
(2)首先 SAGA 按照质押率排名从中选取一定数量的验证者进入出价环节,例如 p= 10 ,那么排名第 11 和第 12 的验证者将被淘汰;
(3)接下来 10 个验证者进行报价,按照报价从低到高进行排序,选择其中 8 个作为委托验证人,同时价格按照 8 个验证者中价格最高者确定,报价为 6 美元和 8 美元的 2 号、 7 号验证者被淘汰,剩下 8 个验证者入围,并同意按照 5 美元进行定价。

这个机制看起来非常复杂,但可以实现一个目标:通过内卷提供尽可能便宜的区块空间(或者叫有效定价)。
以上述案例为例,如果验证者想要获取奖励,就必须确保自己进入前 8 。第一步需要确保自己的质押量足够,这有点类似 EOS 过去的超级节点,第 21 名和第 22 名的奖励存在显著差异。
第二步是通过报价入围。代入单个节点视角,报价 0.01 和报价 5 美元,最终获得的订单价格都是 5 美元,但是 5 美元需要冒着被淘汰的风险,所以尽可能地报低价。
但逐渐地,大部分验证者就会发现这是无止境的内卷,价格逐步向 0 便宜,所以如果考虑到验证者的成本(包括代币的机会成本),更加稳妥的方式是报一个略高于自己成本的价格。所以实际过程中定价会接近【成本 + 少量利润】,长期看会处于一个非常低的区间,这个过程中还会不断淘汰高成本的验证者。
下表可以看出,坎昆升级以后,ETH L2 便宜了很多,但仍然不够便宜,特别是相对 Solana 而言。从技术角度,我们需要 BTC/ETH 这样的安全性,但从商业角度,大规模应用也确实无法承受 0.1 U/ 笔的交易费用,所以「极低并且稳定的费用」是非常有意义的。
另外 SAGA 的收费模式也和其他公链有所区别,用户不需要直接支付网络费用,应用可以自行决定收费方式(例如订阅制、买断制、广告收费甚至完全免费),这也更加符合 Web2 的商业模式惯例,提供了更多灵活性。

另一个有意思的事情是,SAGA 的激励测试网 Saga Pegasus 目前已经有几百个协议,截至 2024 年 4 月 1 日,该计划包括 350 个项目。这些项目中有 80% 是游戏。大约 10% 的项目是 NFT 和娱乐, 10% 是 DeFi。这个数据也和经济模型体现了一致性——SAGA 更加适合轻资产、高用户数量、高用户频次的场景。

最后需要关注的是代币分配,按照 Binance 公布的信息,初始流通量只有 4.5% 的 Launchpool 和 1.5% 的空投,而生态系统和基金会份额基本可以忽略:
(1) 75% 的筹码 Binance Launchpool,抛压非常有限;
(2)总量 15.5% 的空投只发放了 1.5% ,很有可能后面还有很多轮,再考虑到激励测试网上还有几百个项目(可能发币),发币以后 SAGA 仍然值得继续参与(尤其是质押)

Second Half of U.S. Crypto Policy: The Clarity Act Aims for 60 Votes, CFTC's "One-Person Commission" Becomes Biggest Variable

In a pivotal year for US crypto policy, the "CLARITY Act" is advancing in the Senate but faces a high hurdle, needing 60 votes to pass. Key challenges include bridging partisan divides on ethics and swaying undecided Republican senators within a tight legislative calendar of only about 40 working days. The policy "second half" involves intense negotiations on a broader framework for Web3 and DeFi, including crypto tax reforms and the Blockchain Regulatory Certainty Act. A significant uncertainty is the understaffed CFTC, operating with four commissioner vacancies, which complicates regulatory clarity. Meanwhile, the departure of key "crypto champions"—SEC Commissioner Hester Peirce and Senator Cynthia Lummis—will impact ongoing policy efforts. Industry experts are cautiously optimistic but realistic. Sara K. Weed notes that while progress is being made, CLARITY is unlikely to pass this Congress, pushing agencies like the SEC and CFTC to provide more guidance. Sulolit Mukherjee suggests meaningful crypto tax legislation is more likely to be attached to larger must-pass bills. Rashan Colbert discusses the jurisdictional debate over prediction markets, emphasizing the need for a regulatory framework that fosters their development as financial tools rather than treating them broadly as gambling. The clock is ticking, but opportunities remain for substantive progress through continued bipartisan dialogue and pragmatic efforts.

Research Report Analysis: Morgan Stanley Details SanDisk SNDK, The Truth About Cloud Data Center Pricing Power and AI Inference Benefits

Morgan Stanley raised its price target for SanDisk (SNDK) from $1100 to $1750 on June 22, maintaining an Overweight rating. The upgrade is driven by AI inference demand reshaping the NAND market, particularly for KV Cache and context window storage in cloud data centers. These cloud clients exhibit price inelasticity and sign long-term contracts, granting SanDisk significant pricing power. SanDisk's New Business Model (NBM) agreements, covering over one-third of FY27 bit shipments with 3-5 year terms and fixed price/price collar structures, are crucial. They are projected to sustain gross margins around 80% even at floor prices, providing a buffer against cyclical downturns. Morgan Stanley forecasts gross margins to surge from 30.3% in FY25 to 86.7% in FY27e. With NAND supply expected to remain tight into 2026/2027 and cloud/data centers becoming the largest end-market, SanDisk holds supply-side pricing power. The company targets 15-19% bit growth via technology transitions, not capacity expansion. Revenue is projected to grow ~6.6x from FY25 to FY27, with EPS rising from $2.74 to $14.73, driven by high-margin cloud business. Key upside catalysts include faster enterprise SSD adoption and edge AI growth. Downside risks involve slower industry growth, competitor capex increases, market share loss, and competition from Chinese players like YMTC. The investment thesis rests on AI-driven structural demand, NBM's margin protection, and sustained supply tightness. The $1750 target implies ~28x FY27e P/E.

A Threefold Performance Leap! NEAR Achieves 200ms Physical Block Time Limit with SPICE

NEAR's core development team, Near One, has announced its next major protocol evolution: SPICE (Separation of Consensus and Execution). Currently in development, SPICE represents the most significant upgrade before the full implementation of Nightshade 3.0. Its core innovation is decoupling the consensus layer, responsible for ordering transactions, from the execution layer, which processes them. This allows the consensus layer to run at full speed without waiting for transaction execution to complete. Once deployed, SPICE is projected to triple NEAR's block production speed, achieving a 200ms block time, which is considered the physical limit due to the speed of light and network latency. This leap will dramatically reduce transaction latency and finality, with transactions confirming in roughly 0.4 seconds—faster than a typical card payment. The upgrade also enables more complex, long-running transactions and significantly improves user experience for applications like NEAR Intents and near.com. Beyond raw speed, SPICE enhances network scalability and security. It enables deeper parallelism, efficiently distributing workload across shards and improving resource utilization. The simpler block structure and lighter contracts also facilitate formal verification and security auditing. Furthermore, SPICE lays the critical groundwork for future Nightshade 3.0 features, most notably atomic cross-shard transactions, which would simplify complex contract logic and eliminate development hurdles caused by asynchronous execution. The Near One team is actively developing SPICE, targeting deployment in the coming months.
