This is a benchmark for an example Ethereum Smart Contract using Hyperledger Caliper. There are configurations for 3 different blockchains to do the Benchmark:
- Ganache: Simulated local Ethereum Blockchain
- Geth PoW: Local Blockchain using the Go-Ethereum official implementation with the consensus algorithm Proof of Work
- Geth PoA: Local Blockchain using the Go-Ethereum official implementation with the consensus algorithm Proof of Authority
Refer to Ganache and Truffle docs here if this is the first time you use them.
Ganache accounts used by Caliper are hardcoded in benchmarks/configGanache.yaml. Therefore you either need to change them with your ganache addresses or generate the same 10 accounts with ganache using the seed source jewel review offer prosper reform tent carpet cry license hint lottery
Note: There accounts are for testing purposes, don't use them with real Ether ;)
Run the network like I explain in my geth repo and run the command below!
Run the network like I explain in my geth repo and run the command below!
I provided ganache and geth configs (geth based on my other repo) for truffle , just run:
truffle compile
After that you will need to modify the contract build file to specify a gas big enough for caliper not to complain. You can do it manually or run node scripts/prepareBuildedContract.js (it sets it to 300000).
Refer to the official docs if you have doubts running it.
Install dependencies: npm i
The big command, including all the config and network files, would be:
- Ganache:
npx caliper launch manager --caliper-workspace ./caliperWorkspace/ --caliper-benchconfig benchmarks/configGanache.yaml --caliper-networkconfig networks/networkConfigGanache.json - Geth PoW:
npx caliper launch manager --caliper-workspace ./caliperWorkspace/ --caliper-benchconfig benchmarks/configGethPOW.yaml --caliper-networkconfig networks/networkConfigGeth.json - Geth PoA:
npx caliper launch manager --caliper-workspace ./caliperWorkspace/ --caliper-benchconfig benchmarks/configGethPOA.yaml --caliper-networkconfig networks/networkConfigGeth.json
This command will deploy the smart contract and execute the benchmark rounds.
As an alternative, you can run multiple benchmarks in a row from different config files (instead of a bug one), like I did with PoA blockchain. Instead of the previous big command, run:
node scripts/executePOAfolder.js
and wait to finish those 10 benchmarks, you will find the results in caliperWorkspace/benchmarks/results_POA_benchmarks/ (I provided my results as an example, you can delete them though)
NOTE: You can actually run the rounds of PoA with PoW and viceversa, since the network is the same (not at the same time though, just I have in my ethereum-private-blockchain repo 2 nodes that can actually start running a PoW or a PoA network indifferently).
However, PoW is CPU intensive and I have a laptop, not a mining farm, so PoW rounds in the benchmark are pretty small (3200tx total) compared with PoA or ganache rounds (13000tx total each). Feel free to modify those rounds
- Did you set the gas field in your smart Contract build file? Remember that you must set it every time you compile it
