DDO Chain：并行EVM让交易更高效

币界网Published on 2024-07-22Last updated on 2024-07-22

币界网报道：

以比特币为代表的第一代区块链网络以分布式记账的方式开创了去中心化的电子货币交易新模式，革命性地开创了一个新时代。以以太坊为代表的第二代区块链网络则充分发挥想象力，提出以分布式状态机的方式实现去中心化应用（ DApp ）。

 

从那时起，区块链网络开启了它自己十几年飞速发展的历史，从 Web3 基础设施到以 DeFi 、 NFT 、社交网络和 GameFi 等为代表的各种赛道，诞生了无数或技术或商业模式的创新。行业的蓬勃发展需要不断吸引新用户参与去中心化应用的生态建设，这反过来又对产品体验提出了更高的要求，不但要在满足用户需求上有所创新（功能性需求），还要考虑怎样在安全性和性能之间取得平衡（非功能性需求）。

 

尤其是经历了 2020 年 DeFi Summer 以及 2023 年年末比特币生态中铭文的持续爆发，业界迫切需要新的性能提升方案来满足“高性能、低费率”的要求。并行的EVM兼容区块链就是在这样的背景下诞生的。

以太坊对交易的处理是串行的，交易要按顺序一个接一个的执行，资源的利用率不高。如果通过并行的EVM将串行处理的方式变为并行处理将带来性能的巨大提升。DeFi 赛道有“高速低费率”的诉求，游戏赛道有“强实时交互”的诉求，二者都对执行速度有一定要求。并行 EVM 必然会给这些项目带来更好的用户体验，推动行业的发展进入到全新的阶段。

 

从资源管理上看，传统的区块网络是串行地处理交易的，这种处理方法虽然简单，但也是对处理器资源的一种浪费。而并行区块链实现了计算资源的物尽其用，充分”榨干“了多核处理器的性能，提高了区块网络的整体效能。

 

从去中心化应用的发展上看，要吸引更多用户，体验上一定要下功夫。性能优化是提升用户体验的方向之一。对于 DeFi 用户来说，要满足高交易速度，低费率的需求。对于 GameFi 用户来说，要满足实时交互的需求。这些都需要并行执行作为支撑。

 

并行执行能够发挥多核处理器的优势同时处理多个任务，增大系统吞吐量，同时确保得到的交易结果与按顺序串行执行交易时完全相同。

而DDO Chain是EVM兼容的AI智能区块链，DDO在此基础上进行完善，采用并行EVM的方式，通过在一个节点上创建多个 EVM 实例，并且让每个实例都能够独立运行并处理交易，将待处理的交易按照某种策略（如哈希值、时间戳等）分配给不同的 EVM 实例，最后每个 EVM 实例在自己的线程中执行分配给它的交易，多个实例可以同时运行，从而实现交易并行处理，能够让交易更高效。

 

DDO Chain通过并行EVM在多个处理器上同时执行交易，能够显著提升区块链的吞吐量和处理速度，突破了传统顺序处理的限制。而并行 EVM 的发展未来也将继续伴随着技术的不断创新和优化，包括更高效的并行处理算法、更智能的资源管理和更安全的执行环境。这些创新都将进一步提升并行 EVM 的性能和可靠性，从而提升DDO Chain的交易性能。

 

通过实施并行EVM，DDO Chain将可以支持更复杂和多样化的去中心化应用（dApps），特别是在需要高频交易和低延迟的场景下，如去中心化金融（DeFi）、游戏和供应链管理。

A Wave of Resistance Against AI Data Centers Sweeps the U.S., and the Most Vocal Are Not in Wealthy Areas

A nationwide movement against AI data center construction is gaining momentum across the US, from Vermont to California. New York's legislature recently passed a one-year moratorium, and Illinois has paused tax incentives for such projects. A new report, featuring exclusive data analysis from researcher Geoff Holtzman, challenges the narrative that opposition is led by wealthy "NIMBYs." Key findings reveal: 1) Resistance is highest in the poorest communities (19% protest rate) and lowest in the wealthiest (3.8%). 2) Proposed data centers facing community protests are over five times more likely to be canceled or paused (28.2% vs. 5.2%). 3) The higher cancellation rate in low-income areas is directly explained by their higher protest rates. A separate Heatmap poll shows 55% of Americans strongly oppose local data centers, with opposition strongest among Democrats, rural residents, and young adults (80% of 18-35 year olds). The analysis concludes that the anti-data center movement is largely driven by working-class communities and is proving effective at halting projects.

Yang Ge Gary: Agent Economy and AI Sub-Microeconomics

"Agent Economy and AI Submicroeconomics" by Gary Yang discusses the evolution of AI Agent economies, written from Singapore in June 2026. The author observes a significant "civilizational generational gap" in AI development, particularly highlighted by events in Silicon Valley. The article identifies a current bottleneck in the transition from Human-to-Agent (H2A) economies to true Agent-to-Agent (A2A) ecosystems. While AI Payment protocols are rapidly emerging, many implementations remain non-AI-native, focusing on traditional human decision-making models rather than leveraging autonomous Agent decision-making. A core thesis is the inevitable formation of an **Agent Economy**, defined as a system where autonomous AI Agents create, exchange, and capitalize value independently. This requires new infrastructure: **AI Protocols**, which are the foundational rules and standards for Agent interaction. The piece explores the relationship and current gap between AI Protocols and Crypto Protocols, suggesting political and regulatory factors from traditional finance are temporarily constraining development. However, a future fusion into a mature Digital Protocol system is deemed inevitable based on first principles. The author introduces **AI Agent Submicroeconomics**, contrasting it with human economics. Key differences include higher transaction frequency, lower value per transaction, efficiency-driven (not emotion-driven) decisions, task-oriented (not consumption-oriented) behavior, and near-zero organizational and communication costs. A biological analogy is drawn, comparing an Agent to a cell, its LLM to a nucleus, and its protocol stack to a cell membrane. The rise of **AIFi** (AI Finance) is presented as a natural consequence, where value originates from AI-native activities and is subsequently tokenized and financialized. This contrasts with DeFi/TradFi, where finance is the source of value. The concept of a **Financial Chip (FinChip)**—an autonomous AI Agent integrated with a crypto smart contract—is highlighted as key infrastructure for this new economy. The conclusion emphasizes that **AI-Native** thinking represents a paradigm shift distinct from "Internet+" upgrades. It requires reasoning from first principles, focusing on energy-value shortest paths and maximum efficiency, which presents a steep learning curve and significant challenge for all participants in this rapidly evolving field.

ViaBTC CEO Haipo Yang: Looking Back at the Decade, Re-understanding the Value of Crypto

In "A Decade in Retrospect: Re-evaluating the Value of Crypto," ViaBTC & CoinEx CEO Haipo Yang reflects on the cryptocurrency industry's evolution since founding ViaBTC in 2016. Initially a niche interest, Crypto has fundamentally transformed key financial infrastructures like market making, trading, settlement, and issuance through open protocols, as seen with Uniswap and GMX, and enabled efficient cross-border transfers via stablecoins. While acknowledging speculation's role in fueling innovation and liquidity, Yang warns it often overshadows real demand. He distinguishes between blockchain (a trust-minimizing technology), Web3 (an application model requiring genuine utility), and Crypto assets. The latter's value derives from block space as a commodity (e.g., gas fees) and "sovereign liquidity premium" (e.g., Bitcoin's censorship resistance), with most tokens lacking such dual support. Looking ahead, Yang argues the next decade's focus should shift from "open participation" to "sustainable participation," emphasizing reliable infrastructure. He predicts consolidation towards networks with strong security and liquidity (like Bitcoin and Ethereum), and sees DeFi becoming a specialized tool rather than a mass replacement for traditional finance. Crypto will integrate into traditional finance (e.g., via Bitcoin ETFs) but may sacrifice some decentralization for mainstream adoption. Real future demand may come from AI agents and machine economies needing permissionless settlement. Ultimately, Yang believes Crypto's enduring value lies not in hype or replacing everything, but in verifiably reducing trust costs, increasing efficiency, and providing stable, transparent services across market cycles.

Silicon Valley Moguls Gather for 'Werewolf' Reality Show, Billionaires Engage in Power Gameplay

Silicon Valley elites, including OpenAI's Sam Altman, Anduril's Palmer Luckey, and Signal's Moxie Marlinspike, gathered not for a tech discussion, but to film a reality show playing "Mafia" (the US version of Werewolf). The show, titled *MAFIA*, is produced by the legendary venture capital firm Founders Fund. Held at the historic Tosca Cafe in San Francisco, the game revealed participants' real-time decision-making and personalities under pressure. Altman applied analytical logic, Luckey's playful style made him an early target, and Marlinspike skillfully shifted the group's thinking. The session quickly devolved into a battle of intuition and accusation after Figma's Dylan Field was eliminated first. More than just entertainment, the show is seen as a public experiment and a rebellion against standard VC narratives. It demonstrates how Silicon Valley's new elite leverages "infotainment" to build influence. As traditional media wanes, figures like Founders Fund are taking control of content creation, understanding that narrative control and public performance are becoming crucial capital in the internet age. The strategic thinking, persuasive communication, and rapid decision-making displayed in the game mirror the very skills that drive their real-world success.

ChatGPT's "Dreaming" Feature: A Must-Have for All AIs

ChatGPT has introduced a major new "Dreaming" memory system, making its AI assistant more human-like by automatically learning and updating user preferences over time. Unlike the older "Saved memories" feature, which required explicit user commands to store information, the new system actively synthesizes useful details from past conversations—such as travel plans, work projects, or personal interests—and intelligently determines which facts remain relevant and which have become outdated. OpenAI reports significant performance improvements: accuracy in recalling facts rose from 41.5% with the old system to 82.8% with Dreaming V3, while adherence to user preferences increased from 31.4% to 71.3%. A key enhancement is the system's ability to keep information current over time, with accuracy jumping from 9.4% to 75.1%. Users can now view and edit a "Memory Summary" page, see sources that influenced responses, and control memory settings. While the feature initially rolls out to US Plus and Pro users, it will later expand globally and to free-tier users. This evolution marks a shift for ChatGPT from a general conversational model toward a persistent, personalized assistant that builds a long-term understanding of each user—raising both practical possibilities and deeper questions about privacy and the nature of AI-human relationships.
