Role	Required	Description
Blockchain Developer		Understands zk-rollup architecture: sequencer, prover, verifier contract. Studies differences between zkSync, StarkNet, Polygon zkEVM, and Scroll. Deploys zk-rollup node on testnet.
Smart Contract Developer		Understands zk-rollup architecture and how it affects smart contract development. Deploys contracts on zkSync and StarkNet. Studies differences in EVM compatibility (type 1-4 zkEVM).

Role	Required	Description
Blockchain Developer		Configures and operates zk-rollup nodes. Implements proving infrastructure integration. Understands EVM compatibility differences: type 1-4 zkEVM. Monitors proof generation and submission.
Smart Contract Developer		Adapts contracts for zk-rollup deployment: accounts for opcode differences, gas model specifics. Implements cross-layer contract messaging between L1 and zk-rollup. Tests on zkSync testnets.

Role	Required	Description
Blockchain Developer		Designs zk-rollup infrastructure: proving cluster, data availability, forced transaction inclusion. Optimizes prover performance and evaluates proof generation economics.
Smart Contract Developer		Designs contract systems optimized for zk-rollup: minimizing storage slots, optimization for prover efficiency. Analyzes zk-specific vulnerability patterns.

Role	Required	Description
Blockchain Developer		Defines zk-rollup strategy for the organization: platform selection, proving infrastructure, migration plan. Builds team expertise in zkEVM and custom circuit development.
Smart Contract Developer		Defines zk-rollup deployment strategy for smart contract organizations. Establishes zk-specific testing requirements and compatibility guidelines. Coordinates multi-rollup deployment.

Role	Required	Description
Blockchain Developer		Shapes enterprise zk-rollup strategy: custom rollup development, shared prover networks, DA layer selection. Researches zkVM evolution and publishes infrastructure analysis.
Smart Contract Developer		Defines enterprise zk-rollup smart contract strategy. Researches zkVM-native development and custom circuit integration in smart contracts. Publishes zk-rollup contract patterns.
