The Metadium EN (End Node) needs to be capable of handling all block and transaction information on the Metadium blockchain. Therefore, it requires the following recommended and minimum hardware specifications:
vCPU: 8 core
RAM: 32 GB
Storage: At least 1TB SSD
OS: Linux-based operating system
Firewall Requirements
The Metadium EN node requires the following firewall settings to receive blocks from the chain network or propagate new transactions to the network:
Outbound
| SRC | DST | PROTO | PORT | DESC |
|---|---|---|---|---|
EN | all | TCP, UDP | 8589 | P2P |
Inbound
| SRC | DST | PROTO | PORT | DESC |
|---|---|---|---|---|
all | EN | TCP, UDP | 8589 | P2P |
Developers | EN | TCP | 8588 | RPC |
Developers | EN | TCP | 8598 | WebSocket |
The RPC port and WebSocket port are ports the dApp server or developers request using the respective EN node.
