The Full-Sync Node is an available software implementation of a read-only SKALE Node that can help decrease the load on the core nodes of your chain. Applications are commonly read-heavy compared to writes, meaning they pull data from the chain more often than push them. For applications that contain many reads, a full-sync node can help increase chain stability and speed by reducing the number of actions the core nodes on the chain must do, leaving them with a more extraordinary ability to handle transactions.

​
General Steps

  • Provision a machine
  • Notify core team of IP/IPs range (x.x.x.x:x.x.x.x) and SKALE Chain for full-sync.
  • Complete Full Sync setup

​
Node Machine Requirements

  • A Linux x86_64 machine
  • Ubuntu 22.04
  • 8 vCPUs
  • 16GB RAM
  • 100GB root storage
  • 256GB attached storage for MEDIUM chain
  • 2TB attached storage for LARGE chain

​
Node Network Requirements

  • Ports 80, 443, 3009, and 10000–18192, and ICMP IPv4 shouldn’t be closed by external firewall

​
Node Software Prerequisites

  • 16GB Swap
  • docker
  • docker-compose → 1.27.4
  • iptables-persistent, btrfs-progs, lsof, lvm2, psmisc, and apt packages

​
From Fresh Machine

Before proceeding, notify the core team of the IP address of your full-sync node. It’s suggested to use an elastic IP for the whitelisted IP address.

​
Installation

​
Setup SSL certs

Node SSL certificates support secure communication with SKALE Chain endpoints. By default, each node of a SKALE Chain listens on HTTP and WS ports. If SSL certs exist on the node, then HTTPS and WSS ports are also turned on. To upload SSL certs to the node run:
To check the status of your certs run:
Once certs are uploaded, HTTPS/WSS endpoints should become available for your chain.

​
Full sync node update

Update full sync SKALE node on current machine
Options:
  • --yes - update without additional confirmation
Arguments:
  • ENV_FILEPATH - path to env file where parameters are defined
You can just update a file with environment variables used during skale sync-node init.

​
Maintenance

Maintenance commands are not available for a sync node.
