Illia Polosukhin

Illia Polosukhin (born 1989, Kharkiv, Ukraine) is the co-founder and former CEO of NEAR Protocol and one of the co-inventors of the Transformer architecture — the foundational deep learning model introduced in the landmark 2017 paper “Attention Is All You Need,” which became the basis for GPT, BERT, and virtually every major language model since. This makes Polosukhin unique among blockchain founders: he contributed to the single most impactful AI research paper of the 21st century before turning his attention to building a scalable Layer 1 blockchain designed for usability and sharding.

Background

  • Education: MS in Computer Science, Kharkiv National University; self-describes significant self-taught learning
  • Career highlights: Software engineer at Google (Google Brain, Google Research); co-inventor of Transformer architecture
  • Primary affiliation: Co-founder, NEAR Protocol

Key Contributions

Transformer Architecture (AI):

  • Co-author of “Attention Is All You Need” (Vaswani et al., 2017) — the paper introducing the Transformer model
  • The Transformer replaced RNNs and LSTMs as the dominant sequence modeling architecture
  • Directly enabled: GPT-1/2/3/4 (OpenAI), BERT (Google), LLaMA (Meta), Claude (Anthropic), and essentially all modern LLMs
  • One of the most cited papers in the history of machine learning

NEAR Protocol:

  • Co-founded with Alexander Skidanov in 2018
  • NEAR uses Nightshade Sharding — a dynamic sharding approach where each shard (and validator subset) processes a portion of transactions, scaling throughput with the number of shards
  • Human-readable account names (e.g., alice.near instead of hex addresses) — designed for mainstream usability
  • NEAR’s approach to smart contract development supports AssemblyScript and Rust
  • The NEAR Foundation leads ecosystem development and grants

AI x Blockchain Intersection:

  • Polosukhin is a prominent voice on combining AI and blockchain — particularly around provenance, accountability, and verifiability of AI-generated content on-chain
  • Has written and spoken about NEAR’s AI-oriented infrastructure ambitions

Timeline

  • 2016–2017: Works at Google Research; co-authors Transformer paper
  • 2017: “Attention Is All You Need” published — the AI landscape permanently changes
  • 2018: Leaves Google to co-found NEAR Protocol with Alexander Skidanov
  • 2020: NEAR mainnet launches; NEAR Foundation established
  • 2021: NEAR Rainbow Bridge (ETH-NEAR bridge); Aurora (EVM on NEAR) launches
  • 2022: NEAR ecosystem grows; sharding Phase 1 (Nightshade) activates
  • 2024: Polosukhin steps back from CEO role to focus on research; new NEAR leadership takes operational role

Common Misconceptions

“Illia invented AI.”

Polosukhin co-invented the Transformer architecture — a specific (hugely impactful) contribution to deep learning. He is one of 8 co-authors on the Attention paper. The broader field of AI has thousands of contributors.

“NEAR is just another Ethereum competitor.”

NEAR’s design priorities differ meaningfully from Ethereum — specifically in sharding architecture, human-readable accounts, and the target use cases. Polosukhin has emphasized usability and AI-native applications as NEAR’s differentiation.

Criticisms

  • NEAR adoption challenges: Despite a technically sophisticated sharding design and substantial funding, NEAR’s user and TVL metrics lag behind Solana and Ethereum significantly
  • AI narrative: Critics question whether integrating AI and blockchain is technically coherent beyond marketing — the specific mechanisms for verifiable AI computation on NEAR are nascent
  • Ecosystem growth pace: The NEAR ecosystem grew more slowly than comparable L1s despite similar timing and funding levels

Social Media Sentiment

Polosukhin receives significant respect in both AI and blockchain communities — the combination of Transformer co-authorship and blockchain founding is genuinely rare. NEAR ecosystem participants follow his technical writing closely. The AI x blockchain intersection narrative he champions is increasingly popular in 2024 as AI infrastructure became a major crypto narrative. His reputation is primarily positive, built on demonstrable technical contribution rather than marketing.
