- Vitalik Buterin exposes memory flaw crippling blockchain and AI performance.
- New model reveals why bigger memory may actually slow computing speed.
- Blockchain efficiency could depend on smarter memory use, not faster chips.
Ethereum co-founder Vitalik Buterin has revealed a critical computing flaw that could be quietly limiting the speed of blockchains and AI systems. According to his new paper, the common belief that memory access time is constant is inaccurate. Instead, Buterin explains that as memory grows, accessing data becomes slower because signals travel longer distances within the hardware.
His findings challenge decades of assumptions in computer science. Vitalik Buterin proposes that the cube root of memory size determines access time, meaning performance declines as systems scale. This discovery directly impacts how cryptographic and blockchain systems are designed, where speed and efficiency are crucial for network performance.

Buterin supports his model with real-world evidence, showing that latency increases from CPU caches to RAM. The results align closely with his theoretical framework and expose a physical limitation often overlooked in algorithm optimization. This shift in understanding could reshape how developers balance storage and computation in future blockchain infrastructure.
Rethinking Memory for Cryptography and Blockchain Performance
In one example, Buterin points to elliptic curve cryptography, which secures most blockchain networks. Developers often rely on precomputed tables to speed up cryptographic operations. However, his experiments reveal that these large tables can reduce efficiency once they outgrow cache memory. A smaller cache-fitting table performed faster than a larger one stored in main memory.
This insight suggests that bigger is not always better when it comes to data storage. By optimizing how memory is accessed instead of simply increasing capacity, systems could achieve faster and more stable performance. Consequently, blockchain engineers and AI developers may need to focus more on intelligent memory management rather than raw processing power.
Buterin’s analysis could influence the next wave of specialized hardware such as GPUs and ASICs. As blockchain technology advances toward high-performance computing, recognizing the true cost of memory access may be the key to unlocking greater efficiency across cryptographic systems and artificial intelligence networks.
