Runs zksync prover on yagna providers.

• You need zksync dev environment running locally. WARNING: It's not easy!!

  • Clone zksync repo git clone https://github.com/matter-labs/zksync.git
  • Install dependencies and setup environment following this instruction: https://github.com/matter-labs/zksync/blob/master/docs/setup-dev.md
  • Launch zksync locally using instruction: https://github.com/matter-labs/zksync/blob/master/docs/launch.md This will initialize databases and download keys.
  • You will need to be able to send transaction, but it's hard to get ETH on local Geth. One way to workaround this, is to replace Geth docker image in docker-compose.yml in zksync repo with image, that have initialized accounts, that you want. Check docker/geth directory, how I did it.

• Install Yagna Provider (TODO: add links after next release).

• Yagna Requestor doesn't need separate installation, but create app keys following instruction: https://handbook.golem.network/requestor-tutorials/flash-tutorial-of-requestor-development

If you have environment prepared

• Launch zksync environment zk up. This starts docker-compose with local Geth and some other stuff necessary for zksync server to work.
• Launch zksync server zk server.
• Launch Yagna Provider or use public Providers network.
  • If you decide to setup only local provider, remember to set subnet parameter.
• Launch Yagna Requestor
  • Set YAGNA_APPKEY environment variable in your .env or export as shell variable. (Use .env-template as example)
  • yagna service run
• Run ya-zksync-prover. In repo directory type:

  mkdir -p workdir
  cp .env-template workdir/.env
  cd workdir
  cargo run
  

• Add transactions to zksync server. To do this you can use zcli. For example:

  ./zcli deposit 5 ETH 0x0532c4b81d77cbc75f05bb41cedeb1bfb31d6d77
  ./zcli transfer 0.01 ETH 0x91b91be45d70896ed8376384bff01367660f4ae9
  

• ya-zksync-prover should start proving blocks now.

To build docker images run:

./docker/build-dockers.sh

This will build ya-zksync-prover image, that can be converted to vm image and my-geth, that is usefull for running zksync server with initialized accounts.

Yagna Requestor (ya-zksync-node binary) places all downloaded artifacts in the same directory structure as the will appear on Provider. You can run ya-zksync-prover image locally to check if it works properly.

You need blocks and job information to be able to compute proof. You can run Requestor agent that will download all data from zksync server and will place it in your workind directory.
