PANews Editor's Note: On November 25th, Google's total market capitalization reached a record high of $3.96 trillion. Factors contributing to this surge in stock price included the newly released, most powerful AI chip, the Gemini 3, and its self-developed TPU chip. Beyond AI, the TPU will also play a significant role in blockchain technology.
The hardware narrative of modern computing has been largely defined by the rise of the GPU.
From gaming to deep learning, NVIDIA's parallel architecture has become an industry-recognized standard, causing CPUs to gradually shift to a co-management role.
However, as AI models encounter scaling bottlenecks and blockchain technology moves towards complex cryptographic applications, a new competitor, the Tensor Processor (TPU), has emerged.
Although TPU is often discussed within the framework of Google's AI strategy, its architecture unexpectedly aligns with the core needs of post-quantum cryptography, the next milestone in blockchain technology.
This article explains, by reviewing the evolution of hardware and comparing architectural features, why TPUs (rather than GPUs) are better suited to handle the intensive mathematical operations required by post-quantum cryptography when building decentralized networks resistant to quantum attacks.
To understand the importance of TPU, you need to first understand the problems it solves.
The fundamental difference between GPUs and TPUs lies in their data processing methods.
GPUs require repeated access to memory (registers, cache) for computation, while TPUs employ a pulsating architecture. This architecture, like a heart pumping blood, causes data to flow through a large-scale computing cell grid in a regular pulsating manner.
The calculation results are directly passed to the next computation unit without needing to be written back to memory. This design greatly alleviates the von Neumann bottleneck, which is the latency caused by the repeated movement of data between memory and the processor, thereby achieving an order-of-magnitude increase in throughput for specific mathematical operations.
The most critical application of TPU in the blockchain field is not mining, but cryptographic security.
Current blockchain systems rely on elliptic curve cryptography or RSA encryption, which have fatal weaknesses when dealing with Shor's algorithm. This means that once a sufficiently powerful quantum computer becomes available, an attacker could deduce the private key from the public key, potentially wiping out all crypto assets on Bitcoin or Ethereum.
The solution lies in post-quantum cryptography. Currently, mainstream PQC standard algorithms (such as Kyber and Dilithium) are all based on Lattice cryptography.
This is precisely the advantage of TPUs over GPUs. Lattice cryptography heavily relies on intensive operations on large matrices and vectors, primarily including:
Traditional GPUs treat these computations as general-purpose parallel tasks, while TPUs achieve dedicated acceleration through hardware-level fixed matrix computation units. The mathematical structure of Lattice cryptography and the physical construction of the TPU's pulsating array form an almost seamless topological mapping.
While GPUs remain the industry's universal king of all trades, TPUs have a clear advantage when handling specific math-intensive tasks.
Conclusion: GPUs excel in versatility and ecosystem, while TPUs have an advantage in intensive linear algebra computation efficiency, which is the core mathematical operation upon which AI and modern advanced cryptography rely.
Besides post-quantum cryptography, TPUs have also shown application potential in two other key areas of Web3.
ZK-Rollups (such as Starknet or zkSync), as scaling solutions for Ethereum, require massive computations in their proof generation process, mainly including:
These types of operations are not hash calculations, which ASICs excel at, but rather polynomial mathematics. Compared to general-purpose CPUs, TPUs can significantly accelerate FFT and polynomial commitment operations; and because these algorithms have predictable data flow characteristics, TPUs can typically achieve higher efficiency acceleration than GPUs.
With the rise of decentralized AI networks such as Bittensor, network nodes need to have the ability to run AI model inference. Running a general-purpose large language model is essentially performing massive matrix multiplication operations.
Compared to GPU clusters, TPUs enable decentralized nodes to process AI inference requests with lower energy consumption, thereby improving the commercial viability of decentralized AI.
Although most projects still rely on GPUs due to the widespread adoption of CUDA, the following areas are poised for TPU integration, especially within the narrative framework of post-quantum cryptography and zero-knowledge proofs.
Why choose TPU? Because ZK proof generation requires massively parallel processing of polynomial operations, and under certain architecture configurations, TPUs are far more efficient than general-purpose GPUs at handling such tasks.
Why choose a TPU? This is precisely the native application scenario for TPUs, designed specifically to accelerate neural network machine learning tasks.
Why choose TPU? The core operations of post-quantum cryptography often involve the problem of finding the shortest vector in a lattice. These tasks, which require dense matrix and vector operations, are highly similar to AI workloads in terms of computational architecture.
If TPUs are so efficient in post-quantum cryptography and zero-knowledge proofs, why is the industry still scrambling to buy H100 chips?
The future of Web3 hardware is not a winner-takes-all competition, but rather an evolution towards a layered architecture.
GPUs will continue to play a leading role in general computing, graphics rendering, and tasks requiring complex branching logic.
TPUs (and similar ASIC-based accelerators) will gradually become the standard configuration for the Web3 "mathematics layer," specifically designed to generate zero-knowledge proofs and verified quantum cryptographic signatures.
As blockchains migrate to post-quantum security standards, the massive matrix operations required for transaction signing and verification will make the pulse architecture of TPUs no longer an option, but an essential infrastructure for building scalable quantum-safe decentralized networks.
