The blockchain industry faces a paradox: explosive growth coupled with acute talent shortage. Whilst the Web3 ecosystem expands towards £81.5 billion by 2030, only ~25,000 developers actively build on-chain each month. This supply-demand imbalance creates unprecedented opportunity for career transitioners armed with the right educational resources — from completely free self-paced platforms to structured bootcamps with job-placement guarantees.
Structured, cohort-based learning with defined curricula, deadlines, and community support.
