Blockchain projects span a wide range — from genuinely novel consensus and cryptographic research to standard smart contract development using well-documented frameworks. The CRA evaluates these very differently, and the distinction matters more here than in most software subfields.
What Typically Qualifies
● Developing novel consensus mechanisms or cryptographic protocols to solve a specific scalability, security, or finality problem
● Solving cross-chain interoperability challenges where existing bridging methods don’t reliably resolve the specific technical conflict
● Building systems to achieve throughput or latency targets existing protocol designs can’t meet without a new architectural approach
● Researching and testing novel approaches to on-chain privacy or verifiable computation
What Typically Doesn’t Qualify
● Writing smart contracts using standard, well-documented patterns on an established chain
● Deploying and configuring existing DeFi protocol templates
● Building a front-end application that interacts with existing blockchain infrastructure via documented APIs
● Token launches and tokenomics design without an underlying technical uncertainty
A Field Where Hype and Eligibility Diverge
Because blockchain carries a strong innovation narrative, teams sometimes assume the label alone signals SR&ED eligibility. Reviewers apply the same three-part test here as anywhere else — the question is always whether the specific technical outcome was genuinely unpredictable using existing published protocols and standard development patterns, not whether the underlying technology is new to the market.
