🧊Run full node

Full node function

• Stores the full blockchain history on disk and can answer requests for data from the network.

• Receive and validate new blocks and transactions.

• Verify the status of each account.

Support platform

We currently support running full node Linux.

Recommended requirements

Full node

• The VPS runs the latest version of Linux.

• Important 1T GB free disk space, solid state drive (SSD), gp3, 8k IOPS, 250MB/S throughput, read latency <1ms. (NVMe SSD required if starting from snapshot/quick sync)

• 8-core CPU and 16 GB of memory (RAM).

• The recommended instance type is m5zn.3xlarge on AWS and c2-standard-16 on Google Cloud.

• Broadband internet connection with upload/download speed of 5 megabytes per second

Validator

• The VPS runs the latest version of Linux.

• Important 1T GB free disk space, solid state drive (SSD), gp3, 8k IOPS, 250MB/S throughput, read latency <1ms

• 8-core CPU and 16 GB of memory (RAM)

• We recommend the m5zn.3xlarge instance type on AWS, or c2-standard-16 on Google Cloud.

• Broadband Internet connection with upload/download speed of 10 megabytes per second

Synchronous mode

• Quick sync

Default sync mode. Synchronizes a fast-syncing full node by downloading the entire state database, first requesting headers, and then filling in block bodies and receipts. Once the fast sync reaches the best block of the FON smart chain network, it will switch to full sync mode.

• Full sync

Synchronizes a full node from genesis, validating all blocks and executing all transactions. This mode is a bit slower than Quick Sync, but more secure.

Run full node

Sync from snapshot (recommended)

Download the prebuilt binaries from the releases page or follow the instructions below

1.Download binaries

wget https://github.com/FONSmartChain/FSC/raw/master/geth sudo chmod +x geth

2.Download the genesis block

wget https://github.com/FONSmartChain/FSC/raw/master/genesis.json

3.Initialize the genesis block

./geth init --datadir data genesis.json

4.Download static node list

wget https://github.com/FONSmartChain/FSC/raw/master/static-nodes.json -O data/geth/static-nodes.json

5.Start node

./geth --datadir data --networkid 201022 \
--http --http.port 20102 --http.addr 0.0.0.0 --http.api "web3,eth,txpool,net" \
--port 20103
