Increase block gas limit to 90M

Bitkub Chain planned to increasing block gas limit from 65_000_000 to 90_000_000. All validator nodes are required to update the block gas limit.

To increase the block gas limit, please follow below.

1. Download new config.toml and replace the existing file.

// Stop geth service
systemctl stop geth

// Download config.toml
curl https://raw.githubusercontent.com/bitkub-blockchain/bkc-node/main/mainnet/config.toml --create-dirs -o "/bkc-node/mainnet/config.toml"

2. Re-check the config is correct.

GasCeil = 90000000

3. Start geth service

// Start geth service
systemctl start geth
