Besu Private Transaction Bug

I've created a simple contract SimpleStorageFactory that has two methods:

1. create - creates an instance of SimpleStorage
2. count - just emits event with constant 123 (to check that private transactions works)
3. set - calls set method of creates an instance of SimpleStorage

Prerequisites

• truffle
• postman

Setup network

• npx quorum-dev-quickstart@latest --clientType besu --privacy true --outputPath quorum-test-network
• cd quorum-test-network
• git apply ../besu-private-transaction-bug/quorum-test-network.patch
• ./run.sh

There's a small patch that makes ethsigner use member1besu instead of rpcnode, so that we can use eea_sendTransaction through node that has privacy enabled.

Setup postman

• import collection to Postman

Deploy contract

• inside besu-private-transaction-bug, run truffle migrate --reset -f 1
• if necessary, update contract address (from truffle output) in postman collection, variable contract_addr (if it's 0x51A21A51aa59B0b4BF99Ea7a79c7293d601FF689, it's already set up)
• check other postman variables (from_addr is address that was setup in ethsigner, member1_public_key and member2_public_key are tessera public keys for first two members)

Scenarios (all in postman)

Before anything

• run request: Create Privacy Group

2. private:

• request: count/Create Private Transaction
• request: Get Private Transaction Receipt

Create (public works, private doesn't)

3. public:

• request: create/Create Public Transaction
• request: Get Public Transaction Receipt
  • expect to see 2 logs (one is from SimpleStorageFactory, another from SimpleStorage)

4. private:

• request: create/Create Private Transaction
• request: Get Private Transaction Receipt
  • expect to see 2 logs (one is from SimpleStorageFactory, another from SimpleStorage)
  • but got: "status": "0x0", and error in log: Failed to process private transaction 0xe379a9658662d1fc0e8837f57b3ded8b0151d10d1d07512ac1d9385935173d8a: PRIVATE_TRANSACTION_FAILED

Set (public works, private doesn't)

5. public:

  • expect to see 1 log

6. private:

• request: create/Create Public Transaction

Notes

• data in both Create Public Transaction and Create Private Transaction was generated by script in scripts/abi-encode.ts, which can be run by node run scripts/abi-encode.ts.
