Problem Definition

It would be great to get TPS measurements for the cadence 1.0 branch even before we merge into master. To do this we first need to update some cadence scripts/transactions/contracts in the TPS benchmark.

Proposed Solution

Update TPS benchmarks to work with cadence 1.0

Definition of Done

• [ ] Run automated TPS benchmarks on stable cadence feature branch.
