NeoBlocks node

The NeoBlocks node is a modified version of the official NEO node allowing event logs to be requested for each invocation transaction. The event logs contain details about a contract execution including notifications and contract storage manipulations. The NeoBlocks agent requires a NeoBlocks node.

Get the sources

git clone https://github.com/NeoBlocks/neoblocks-node.git
cd neoblocks-node
git submodule update --init

Build the Docker image

docker build -t neoblocks/neoblocks-node:2.12.1 .
docker tag neoblocks/neoblocks-node:2.12.1 neoblocks/neoblocks-node

Create a Docker network bridge

docker network create -d bridge neoblocks

Create a directory to store the chain

NEOBLOCKS=/usr/local/neoblocks
mkdir -p "${NEOBLOCKS}/Chain_00746E41"
mkdir -p "${NEOBLOCKS}/EventLogs_00746E41"

Start the container

docker run -it -d \
 --network=neoblocks \
 --restart=unless-stopped \
 --log-opt max-size=16m \
 --name neoblocks-node \
 -p 10332-10334:10332-10334 \
 -v ${NEOBLOCKS}/Chain_00746E41:/app/Chain_00746E41 \
