Blockchain Lab(19) - Configuring the console in the newly created scale-free network

In the previous article Blockchain Lab (18) - Setting up a scale-free network using FISCO BCOS A network was set up , this network has not yet been configured with a console. The FISCO-BCOS technical document gives a creation of a 4-node network and console. That console cannot be directly used for the scale-free network in this article, mainly because the console certificate does not match.

This article is a scale-free network created previously, with a dedicated console configured. It is very common to set up multiple FISCO networks in an experimental environment. It is best to configure a separate console for each network for ease of use.

1. Download

According to FISCO technical documentation, download the download_console.sh script.

curl -LO https://github.com/FISCO-BCOS/console/releases/download/v2.9.2/download_console.sh

Execute this script.

chmod +x download_console.sh
./download_console.sh

Get a console compressed file and the decompressed folder console.

2. Configuration

2.1 To configure common parameters of the console, please refer to FISCO technical documentation.

cp -n console/conf/config-example.toml console/conf/config.toml

2.2 Configure the certificate of the console and copy the files in the sdk directory to the conf directory

3. Test

3.1 Start a scale-free network with 100 nodes

3.2 Start the console

4. Test the contract in the console

Deploy contract cases. 100 nodes reached a consensus, and it was obvious that there was a large delay in deploying the contract.

Call the contract interface. Similarly, the delay is large and the cost of PBFT consensus is high.

The experimental environment is as follows
