Run BRP Node

As discussed in the setup section, there are two ways to setup the node and so accordingly these instructions are below:

Run with Docker Compose - (Recommended method - Beginner)
Build & Run from Source - (Optional method - Advanced)

1. Steps to Run Node with Docker:

Clone Repo

Note: The current BRP-Refiner stable version is 0.6.1. For the latest updates or additional details, please check the announcements or discussions in Discord.

Clone the covalenthq/refiner repo.

git clone https://github.com/covalenthq/refiner
cd refiner
cat docker-compose-mbeam.yml

Check global environment variables

$ cat .envrc
export IPFS_PINNER_URL="http://ewm-das:5080/api/v1"
export EVM_SERVER_URL="http://evm-server:3002"
[[ -f .envrc.local ]] && source_env .envrc.local

Set local environment variables

$ touch .envrc.local
export BLOCK_RESULT_OPERATOR_PRIVATE_KEY="<<BRP-OPERATOR-PK-WITHOUT-0x-PREFIX>>"
export NODE_ETHEREUM_MAINNET="<<HTTPS-MOONBEAM-RPC-URL>>"
export IPFS_PINNER_URL="http://ewm-das:5080/api/v1"
export EVM_SERVER_URL="http://evm-server:3002"
export W3_AGENT_KEY="<<AGENT_KEY>>"
export W3_DELEGATION_FILE="<<DELEGATION_PROOF_FILE_PATH>>"

Note: .envrc.local overrides any env vars set with .envrc on calling direnv allow . Note: When passing the private key into the env vars as above please remove the 0x prefix so the private key env var has exactly 64 characters.

BLOCK_RESULT_OPERATOR_PRIVATE_KEY: Your personal Block Result Producer (BRP) operator private key
AGENT_KEY & PROOF.OUT File: Your personal web3.storage Agent key & Delegation file use by the ipfs-pinner service
IPFS_PINNER_URL: Service (ipfs-pinner) used by rudder to access IPFS assets like Block Specimens (service is automatically invoked and run with the in repo docker compose files eg: docker-compose-mbeam.yml)
EVM_SERVER_URL: Service (evm-server) used by rudder for stateless execution of Block Specimens into indexable (queryable) Block Results

Start Services

Load env vars into the shell.

$ direnv allow .

#make sure you see these being loaded
direnv: loading ~/refiner/.envrc
direnv: loading ~/refiner/.envrc.local
direnv: export +BLOCK_RESULT_OPERATOR_PRIVATE_KEY +EVM_SERVER_URL +IPFS_PINNER_URL +NODE_ETHEREUM_MAINNET +W3_AGENT_KEY +W3_DELEGATION_FILE

Copy over the delegation proof file to ~/.ipfs repo. You should have gotten this from Covalent in addition to the W3_AGENT_KEY value.

mv path_to_delegation_file ~/.ipfs/proof.out

Start all 4 services in the background for Moonbeam

$ docker compose -f "docker-compose-mbeam.yml" up -d --remove-orphans
    [+] Running 4/4
    ⠿ Container refiner      Started                            3.2s

    ⠿ Container evm-server   Started                            1.8s

NOTE: On a system where an das-pinner instance is already running, check the instruction in the Appendix to run refiner docker alongside.

Monitor the logs for Block Result submissions.

$ docker compose -f "docker-compose-mbeam.yml" logs -f –tail 2

refiner       | [info] found 0 bsps to process

Check step 7 in Run BRP from source section below for a successful Refiner stack run log output with performance metrics.

Deployment As Service Unit:

Here you can find an example of a systemd service unit file that can be used to auto-start/restart of the docker-compose service for Refiner.

[Install]
WantedBy=multi-user.target

After adding the env vars in their respective fields in the service unit file, enable the service and start it.

sudo systemctl enable refiner-compose.service
sudo systemctl start refiner-compose.service

Note 1: When passing the private key into the env vars as above please remove the 0x prefix so the private key env var has exactly 64 characters. Note 2: In order to run docker compose as a non-root user for the above shown service unit you need to create a docker group (if it doesn’t exist) and add the user (say) “blockchain” to the docker group

sudo groupadd docker
sudo usermod -aG docker blockchain
sudo su - blockchain
docker run hello-world

Hurray! You have Successfully implemented the BRP Node using Docker Compose

2. Steps to Run Node with Source:

Here, to run the node from source we need to manually run all the three services step by step, follow this guide for implementing

EVM-Server
DAS-Pinner
Block Results Producer

1. Run EVM-Server

The EVM-Server is a stateless EVM block execution tool. It’s stateless because in Ethereum nodes like geth, it doesn’t need to maintain database of blocks to do a block execution or re-execution. The evm-server service transforms Block Specimens to Block Results entirely on the input of underlying capture of Block Specimen data.

Clone & Build evm-server

Clone covalenthq/erigon that contains the fork for this particular stateless execution function, Current stable version is v1.3.2-evm, build the evm-server binary

$ make evm

Run the generated binary

$ ./build/bin/evm t8n --server.mode
[INFO] [06-22|13:53:54.148] Listening port=3002

Note: evm-server occupies the port 3002 on your local at http://127.0.0.1:3002”, so make sure this port in not occupied by any other service prior to start.

2. Run DAS-Pinner

DAS-Pinner serves as the interface to the storage layer of the network. It’s a lightweight IPFS service that stores and pins data on the IPFS network using web3.storage. It is designed to work seamlessly with the DAS Light-Client, enabling the retrieval of data from the IPFS network and its verification using the DAS protocol.
It is meant for uploading/fetching network artifacts (like block specimens and block results or any other processed block data) files of the Covalent Decentralized Network.

Clone & Build ewm-das(pinner)

Clone covalenthq/ewm-das and build the pinner server binary

$ git clone https://github.com/covalenthq/ewm-das.git 
$ cd ewm-das
$ git checkout tags/v0.17.6 ## update if newer release is announced
$ ./install-trusted-setup.sh
$ make build-pinner

Set the environment variable required by

ipfs-pinner by getting W3_AGENT_KEY & Proof.out from web3.storage and adding it to an .envrc file.

$ cat .envrc
export W3_AGENT_KEY="<<W3_AGENT_KEY>>"
export W3_DELEGATION_FILE="<<DELEGATION_PROOF_FILE_PATH>>"

Start the das-pinner server

You should get the “w3 agent key” and “delegation proof file” from Covalent. After that, start the ipfs-pinner server.

./bin/pinner -w3-agent-key $W3_AGENT_KEY -w3-delegation-file $W3_DELEGATION_FILE

generating 2048-bit RSA keypair...done
peer identity: QmZQSGUEVKQuCmChKqTBGdavEKGheCQgKgo2rQpPiQp7F8

Computing default go-libp2p Resource Manager limits based on:
    - 'Swarm.ResourceMgr.MaxMemory': "17 GB"
    - 'Swarm.ResourceMgr.MaxFileDescriptors': 61440

Applying any user-supplied overrides on top.
Run 'ipfs swarm limit all' to see the resulting limits.

2023/04/20 12:47:49 Listening...

Note: das-pinner occupies the port 5080 on your local at http://127.0.0.1:5080/api/v1, so make sure this port in not occupied by any other service prior to start.

Debugging: Repo Migrations

In case of the following error

2023-03-10T08:46:18.621-0800	FATAL	ipfs-pinner	ipfs-pinner/pinner.go:29	error initializing ipfs node: ipfs repo needs migration, please run migration tool.
See https://github.com/ipfs/fs-repo-migrations/blob/master/run.md
Sorry for the inconvenience. In the future, these will run automatically.

Run the following migrations

wget https://dist.ipfs.tech/fs-repo-migrations/v2.0.2/fs-repo-migrations_v2.0.2_darwin-arm64.tar.gz
tar -xvf fs-repo-migrations_v2.0.2_darwin-arm64.tar.gz
cd fs-repo-migrations/
./fs-repo-migrations

3. Run Block Results Producer (BRP):

BRP is the primary orchestrator and supervisor for all transformation pipeline processes that locates a source Covalent Network data object to apply a tracing/execution/transformational rule to and outputs a new object generated from using such a rule. Both the source and output are available through a decentralized storage service such as a wrapped IPFS node. A transformation-proof transaction is emitted, confirming that it has done this work along with the output content ids (ipfs) access URL. To define what these three components are: Source: The Block Specimen that serves as an input to the Refiner. Proof transactions made earlier to a smart contract with the respective cids (content ids) are where the source is checked. Rule: A transformation plugin (or server) that can act on the Block Specimen (source). These can be compared to blueprints that have been shown to produce the data objects needed. Furthermore, anyone can create these rules to get a desired data object. Rule (or server) versions thus need to exist, tied to the decoded block specimen versions they are applied on. Target: The output generated from running the rule over the object that came from the source that is the block result.

Steps to Run BRP:

Clone Refiner

Clone the refiner repo

git clone https://github.com/covalenthq/refiner.git
cd refiner
git checkout tags/v0.6.1

Get your BLOCK_RESULT_OPERATOR_PRIVATE_KEY that has GLMR tokens for Moonbeam and is already whitelisted as Block Result Producer operator. Set the following environment variables for the local refiner by creating an .envrc.local file

Copy paste the environment variables into this file

touch .envrc.local

export BLOCK_RESULT_OPERATOR_PRIVATE_KEY="BRP-OPERATOR-PK-WITHOUT-0x-PREFIX"
export NODE_ETHEREUM_MAINNET="<<ASK-ON-DISCORD>>"
export IPFS_PINNER_URL="http://127.0.0.1:5080/api/v1"
export EVM_SERVER_URL="http://127.0.0.1:3002"

Load envrc file

Call to load .envrc.local + .envrc files with the command below and observe the following output, make sure the environment variables are loaded into the shell.

Once the env vars are passed into the .envrc.local file and loaded in the shell with direnv allow ., build the refiner application for the prod env i.e moonbeam mainnet or dev env for moonbase alpha as discussed before.

    $ direnv allow .

    #make sure you see these being loaded
    direnv: loading ~/refiner/.envrc
    direnv: loading ~/refiner/.envrc.local
    direnv: export +BLOCK_RESULT_OPERATOR_PRIVATE_KEY +EVM_SERVER_URL +IPFS_PINNER_URL +NODE_ETHEREUM_MAINNET +W3_AGENT_KEY +W3_DELEGATION_FILE

Get required dep for Refiner app

Get all the required dependencies and build the refiner app.

mix local.hex --force && mix local.rebar --force && mix deps.get

Build Refiner app

For moonbeam mainnet.
For moonbase alpha.

Start the Refiner

Start the refiner application and execute the proof-chain block specimen listener call which should run the Refiner pipeline pulling Block Specimens from IPFS using the cids read from recent proof-chain finalized transactions, decoding them, and uploading and proofing Block Results while keeping a track of failed ones and continuing (soft real-time) in case of failure.The erlang concurrent fault tolerance allows each pipeline to be an independent worker that can fail (for any given Block Specimen) without crashing the entire pipeline application. Multiple pipeline worker children threads continue their work in the synchronous queue of Block Specimen AVRO binary files running the stateless EVM binary (evm-server) re-execution tool.

Alternatively - check proof-chain logs for correct block result proof submissions and transactions made by your block result producer. For moonbeam. For moonbase.

Note: For any issues associated with building and re-compiling execute the following commands, that cleans, downloads and re-compiles the dependencies for refiner.

rm -rf _build deps && mix clean && mix deps.get && mix deps.compile

If you got everything working so far. Congratulations! You’re now a Refiner operator on the CXT Network. Set up Grafana monitoring and alerting from links in the additional resources section.

Troubleshooting

To avoid permission errors with ~/.ipfs folder execute the following in your home directory.

sudo chmod -R 770 ~/.ipfs

To avoid netscan issue execute the following against ipfs binary application.

sudo chmod -R 700 ~/.ipfs
ipfs config profile apply server

To avoid issues with ipfs-pinner v1.1.0, a small repo migration for the local ~/.ipfs directory may be needed from - here. For linux systems follow the below steps.

wget https://dist.ipfs.tech/fs-repo-migrations/v2.0.2/fs-repo-migrations_v2.0.2_linux-amd64.tar.gz
tar -xvf fs-repo-migrations_v2.0.2_linux-amd64.tar.gz
cd fs-repo-migrations
chmod +x ./fs-repo-migrations
./fs-repo-migrations

Bugs Reporting Contributions

Please follow the guide in docs contribution guidelines for bug reporting and contributions.

Scripts

In order to run the Refiner docker compose services as a service unit. The example service unit file in docs should suffice. After adding the env vars in their respective fields in the service unit file, enable the service and start it.

sudo systemctl enable refiner-compose.service
sudo systemctl start refiner-compose.service

Note:: To run docker compose as a non-root user for the above shown service unit, you need to create a docker group (if it doesn’t exist) and add the user “blockchain” to the docker group.

sudo groupadd docker
sudo usermod -aG docker blockchain
sudo su - blockchain
docker run hello-world

Appendix

Run With Existing IPFS-Pinner Service

On a system where an ipfs-pinner instance is already running, use this modified .envrc.local and docker-compose-mbeam.yml

export BLOCK_RESULT_OPERATOR_PRIVATE_KEY="BRP-OPERATOR-PK-WITHOUT-0x-PREFIX"
export NODE_ETHEREUM_MAINNET="<<ASK-ON-DISCORD>>"
export IPFS_PINNER_URL="http://host.docker.internal:5080/api/v1"
export EVM_SERVER_URL="http://evm-server:3002"

Note: When passing the private key into the env vars as above please remove the 0x prefix so the private key env var has exactly 64 characters.
