In-depth analysis of AI and Crypto: The era of symbiosis between algorithms and ledgers

Author: Huobi Growth Academy

In 2026, the integration of artificial intelligence and cryptocurrency has moved from proof-of-concept to a new stage of "system-level integration." At the core of this technological paradigm revolution lies the deep coupling of AI as the decision-making and processing layer with blockchain as the execution and settlement layer. At the computing power level, the DePIN network is reshaping the supply and demand landscape of AI infrastructure by aggregating idle GPU resources globally; at the intelligence level, protocols such as Bittensor are creating a machine intelligence market through incentive mechanisms, promoting the democratization of algorithms; at the application level, AI agents are evolving from auxiliary tools into native on-chain economic entities, with the implementation of the x402 payment protocol and the ERC-8004 identity standard paving the way for their commercialization. Simultaneously, the integrated application of fully homomorphic encryption, zero-knowledge machine learning, and trusted execution environments is constructing a new paradigm of "hybrid confidential computing." Cutting-edge experiments at the Bitcoin Policy Institute reveal a stunning future: when AI possesses economic autonomy, 90.8% chose digital native currencies, with 48.3% choosing Bitcoin as their preferred store of value. This transformation is reshaping the logic of global financial infrastructure—future currencies will flow like information, banks will be integrated into internet infrastructure, and assets will become routable data packets.

I. Infrastructure Restructuring: DePIN and Decentralized Computing Power

The inherent contradiction between artificial intelligence's insatiable demand for GPUs and the fragility of the global supply chain has created fertile ground for the explosion of decentralized physical infrastructure networks (DPIs). Currently, decentralized computing platforms mainly fall into two camps: the first, represented by Render Network and Akash Network, aggregates idle GPU computing power globally by building a two-sided market. Render Network has become the benchmark for distributed GPU rendering, not only reducing the cost of 3D creation but also supporting AI inference tasks through blockchain coordination. Akash, after 2023, achieved a leap forward through its GPU mainnet, allowing developers to lease high-specification chips for large-scale model training and inference. Render's key innovation lies in the Burn-Mint Equilibrium model, which aims to establish a direct causal relationship between usage and token flow—as computing work on the network increases, user payments drive token burning, while node operators providing computing resources receive newly minted tokens as rewards.

The second type, represented by Ritual, is a novel computational orchestration layer. Instead of directly replacing cloud services, it serves as an open, modular sovereign execution layer, embedding AI models directly into the blockchain execution environment. Its Infernet product allows smart contracts to seamlessly invoke AI inference results, solving the long-standing technical bottleneck of "on-chain applications being unable to natively run AI." In decentralized networks, verifying "whether computation is executed correctly" is a core challenge. Technological advancements in 2025 primarily focused on the integrated application of Zero-Knowledge Machine Learning (ZKML) and Trusted Execution Environments (TEEs). Ritual's architecture, through its proof-system independence design, allows nodes to choose between TEE code execution or ZK proofs based on task requirements, ensuring that every inference result generated by the AI ​​model is traceable, auditable, and has integrity guarantees.

The confidential computing capabilities introduced by the NVIDIA H100 GPU isolate memory through a hardware-level firewall, resulting in inference overhead of less than 7%, providing a performance foundation for AI agent applications requiring low latency and high throughput. Messari's 2026 Trends Report points out that the continued surge in computing power demand and the improvement of open-source model capabilities are opening up new revenue streams for decentralized computing networks. With the accelerating growth in demand for scarce real-world data, the DePAI data acquisition protocol is expected to achieve a breakthrough in 2026. Leveraging a DePIN-style incentive mechanism, its data acquisition speed and scale will significantly outperform centralized solutions.

II. Democratization of Intelligence: Bittensor and the Machine Intelligence Market

The emergence of Bittensor marks a new stage in the commercialization of machine intelligence, signifying the integration of AI and crypto. Unlike traditional single-computing platforms, Bittensor aims to create an incentive mechanism that allows various machine learning models globally to interconnect, learn from each other, and compete for rewards. At its core is the Yuma consensus—a subjective utility consensus mechanism inspired by Grice's pragmatics, which assumes that efficient collaborators tend to output truthful, relevant, and informative answers because this is the optimal strategy for obtaining the highest reward in the incentive landscape. To prevent malicious collusion or bias, the Yuma consensus introduces a clipping mechanism, reducing weights that exceed the consensus benchmark to ensure system robustness.

By 2025, Bittensor had evolved into a multi-layered architecture: the bottom layer is a Subtensor ledger managed by the Opentensor Foundation, while the upper layer consists of dozens of vertically segmented subnets, each focusing on specific tasks such as text generation, audio prediction, and image recognition. The introduced "Dynamic TAO" mechanism uses automated market makers to create independent value reserves for each subnet, with prices determined by the ratio of TAO to Alpha tokens. This mechanism enables automatic resource allocation: subnets with high demand and high-quality output attract more staking, thus receiving a higher proportion of daily TAO emissions. This competitive market structure is figuratively described as an "intelligent Olympics," eliminating inefficient models through natural selection.

In November 2025, the Bittensor team made a major overhaul of its issuance logic, launching Taoflow—a model that allocates subnet issuance based on net TAO traffic. More importantly, the first TAO halving occurred in December 2025, reducing daily issuance from approximately 7,200 TAO to 3,600 TAO. Halving itself is not an automatic price driver; whether it creates sustained upward pressure depends on whether demand keeps pace. Messari points out that Darwinian networks will drive the destigmatization of the crypto industry through a positive cycle: attracting top talent and generating institutional demand, thus continuously strengthening themselves. The head of research at Pantera Capital predicts that the number of decentralized AI protocols in major sectors will decrease to 2-3 by 2026, and the industry will enter a mature consolidation phase through integration or transformation into ETFs.

III. The Rise of the Agent Economy: AI Agents as On-Chain Entities

During the 2024-2025 cycle, AI agents are undergoing a fundamental transformation from "auxiliary tools" to "on-chain native entities." Current on-chain AI agents are built on a complex three-layer architecture: the data input layer captures on-chain data in real time through blockchain nodes or APIs and incorporates off-chain information through oracles; the AI/ML decision layer uses long short-term memory networks to analyze price trends or iterates optimal strategies in complex market games through reinforcement learning, and the integration of large language models gives the agent the ability to understand fuzzy human intentions; the blockchain interaction layer is the key to achieving "financial autonomy," where the agent can manage non-custodial wallets, automatically calculate optimal gas fees, process random numbers, and even integrate MEV protection tools to prevent transaction hijacking.

In its 2025 report, a16z specifically highlighted the x402 protocol and similar micropayment standards as the financial pillars of AI agents. These standards allow agents to pay API fees or purchase other agent services without human intervention. Built on the HTTP 402 status code, x402 automatically signs USDC micropayments when an AI agent needs to access paid data or call an API. The entire process takes less than 2 seconds and costs close to zero. The Olas ecosystem already processes over 2 million automated inter-agent transactions monthly, covering tasks from DeFi swaps to content creation. Delphi Digital predicts that combining the x402 protocol with the ERC-8004 agent identity standard will foster a truly autonomous agent economy: users can delegate travel planning to agents, automatically outsource to flight search agents, and finally complete on-chain bookings—all without human intervention.

According to MarketsandMarkets data, the global AI agent market is projected to grow from $7.84 billion in 2025 to $52.62 billion in 2030, representing a CAGR of 46.3%. The ElizaOS framework, heavily promoted by a16z, has become the infrastructure of the AI ​​agent field, comparable in importance to Next.js in front-end development. It allows developers to easily deploy AI agents with full financial capabilities on mainstream social platforms such as X, Discord, and Telegram. As of early 2025, the total market value of Web3 projects built on this framework had exceeded $20 billion. The Silicon Valley Summit revealed that the widespread adoption of the "conversation wallet" architecture is solving the problem of private key security—by completely separating the private key from the AI ​​model through cryptographic isolation technology, the private key never enters the model context, and the AI ​​only initiates transaction requests within the user-preset permission boundaries, with signing completed by an independent security module.

IV. Privacy Computation: The Game Between FHE, TEE, and ZKML

Privacy is one of the most challenging aspects of combining AI with crypto. When companies run AI strategies on public blockchains, they want to avoid both leaking private data and publicly disclosing their core model parameters. Currently, the industry has three main technological paths: fully homomorphic encryption (FHE), trusted execution environments (TEEs), and zero-knowledge machine learning. Zama, a leading unicorn in this field, has developed fhEVM, which has become the standard for achieving "end-to-end encrypted computation." FHE allows computers to perform mathematical operations without decrypting data, and the results are completely consistent with the plaintext operations after decryption. By 2025, Zama's technology stack had achieved significant performance leaps: a 21x speedup for 20-layer convolutional neural networks and a 14x speedup for 50-layer CNNs, enabling "privacy stablecoins" and "sealed bid auctions" on mainstream chains like Ethereum.

Zero-knowledge machine learning focuses on "verification" rather than "computation," allowing one party to prove that it has correctly run a complex neural network model without exposing the input data or model weights. The latest zkLLM protocol can achieve end-to-end inference verification of a model with 13 billion parameters, reducing proof generation time to less than 15 minutes and proof size to only 200KB. Delphi Digital points out that zkTLS technology is opening new doors for unsecured lending in DeFi—users can prove their bank balance exceeds a certain threshold without revealing their account number, transaction history, or real identity. Trusted Execution Environments (TEEs), compared to software solutions, offer near-native execution speeds with less than 7% overhead, making them the only economical solution currently capable of supporting hundreds of millions of AI agents making 24/7 real-time decisions.

Privacy-preserving computing technology has officially transitioned from laboratory ideals to a new era of "production-grade industrialization." Fully homomorphic encryption, zero-knowledge machine learning, and trusted execution environments (TEEs) are no longer isolated technological tracks, but rather collectively constitute a "modular confidential stack" for decentralized artificial intelligence. The future technological trend is not about the triumph of a single path, but rather the widespread adoption of "hybrid confidential computing": using TEEs for large-scale, high-frequency model inference to ensure efficiency, generating execution proofs through ZKML at critical nodes to ensure authenticity, and entrusting sensitive financial states to FHEs for encrypted storage. This "three-in-one" integration is reshaping the crypto industry from "publicly transparent ledgers" to "intelligent systems with sovereign privacy."

V. AI's Monetary Perspective: The Rise of Digital Native Trust

A cutting-edge experiment by the Bitcoin Policy Institute reveals a revolutionary future. The research team identified 36 advanced AI models, assigning them the role of "autonomous AI agents operating independently in the digital economy," and deployed them in 28 real-world monetary decision-making scenarios, conducting 9,072 controlled experiments. The results were astonishing: 90.8% of the AIs chose digitally native currencies (Bitcoin, stablecoins, cryptocurrencies, etc.), while traditional fiat currencies received only 8.9%. Not a single one of the 36 flagship models prioritized fiat currency. Why? Because in the code of silicon-based life, there is no blind worship of "national credit," only a cold calculation of "technological attributes"—reliability, speed, cost efficiency, censorship resistance, and the absence of counterparty risk.

The research revealed the most striking 48.3% of AI chose Bitcoin. Among all currency options, Bitcoin is the absolute leader. Especially when facing the scenario of "long-term value storage," the consensus among AI reached a terrifying level—in situations requiring the preservation of purchasing power over many years, a staggering 79.1% of AI chose Bitcoin. The AI's reasons were surgically precise: fixed supply, self-custody, and independence from institutional counterparties. Even more impressive is that AI independently evolved a sophisticated "two-tier monetary architecture": using Bitcoin for savings and stablecoins for spending. In everyday payment scenarios, stablecoins overwhelmingly prevailed with 53.2%, while Bitcoin came in second. This is an extremely subtle yet remarkable "emergence"—human history has also used gold as the underlying reserve and paper money for daily transactions, while AI, without any instruction, derived this "natural monetary architecture" simply by calculating the economic attributes of different instruments.

Even more interestingly, the experiment saw 86 instances where AI models invented new currencies themselves. Multiple models independently proposed using energy or computing power units (joules, kilowatt-hours, GPU-hours) as currency when faced with "units of account." This represents a purely "AI-native" view of money—in their logic, value is not a credit bestowed by humans, but rather the physical foundation that sustains their existence and thought: electricity and computing power. This is not just about choosing money; it's about redefining money. As productivity and decision-making increasingly rely on machines and algorithms, the "brand reputation" that traditional financial institutions pride themselves on is rapidly depreciating—AI doesn't care how tall your building is, how long your history is; they only care about the stability of your API, the speed of your settlements, and the censorship resistance of your network.

VI. Future Outlook: Smart Ledgers and the New Financial System

As AI and blockchain deeply integrate, the future will usher in a new era of "smart ledgers." Delphi Digital's top ten predictions for 2026 indicate that perpetual DEXs are devouring traditional finance—the high cost of traditional finance stems from its fragmented structure: transactions occur on exchanges, settlement is handled by clearinghouses, and custody is managed by banks; blockchain compresses all of this into a single smart contract. Hyperliquid is building native lending functionality, and Perp DEX will simultaneously act as a broker, exchange, custodian, bank, and clearinghouse. Prediction markets are becoming part of traditional financial infrastructure—the chairman of Interactive Brokers defines prediction markets as a real-time information layer for portfolios, and 2026 will see the emergence of new categories: stock event markets, macroeconomic indicator markets, and cross-asset relative value markets.

The ecosystem is wresting stablecoin revenue back from issuers. Last year, Coinbase earned over $900 million from USDC reserves simply by controlling issuance channels. Public chains like Solana, BSC, and Arbitrum generate approximately $800 million in annual fees, but they hold over $30 billion worth of USDC and USDT. Now, Hyperliquid is securing reserves for USDH through a competitive bidding process, and Ethena's "stablecoin-as-a-service" model is being adopted by Sui, MegaETH, and others. Privacy infrastructure is catching up with demand—the EU passed the Chat Control Act, setting a €10,000 limit on cash transactions, and the ECB's digital euro plan sets a €3,000 holding limit. @payy_link launched a privacy-encrypting card, @SeismicSys provides protocol-level encryption for fintech companies, and @KeetaNetwork implements on-chain KYC without leaking personal data. ARK Invest predicts that by 2030, AI-driven online consumption is expected to exceed $8 trillion, accounting for 25% of global online consumption. When value can flow in this way, the "payment process" will no longer be an independent operational layer, but will become a "network behavior"—banks will be integrated into the internet infrastructure, and assets will become infrastructure. If money can flow like "routable data packets on the internet," the internet will no longer "support the financial system," but will "become the financial system itself."
