Types of Nodes ​

Xian Network has 3 types of nodes

Validator Nodes

  • Validators are responsible for creating & validating blocks.
  • A block is considered valid when 75% of validators vote for a block.

Full Nodes

  • Full nodes keep a copy of the entire history & state of the blockchain.
  • They are a key component to keeping the network healthy.

Blockchain Data Service Nodes

Blockchain Data Service (BDS) nodes improve developer experience by providing :

  • Rich data & querying via REST & Websocket interfaces
  • Stamp estimation, allowing a dAPP to know how many stamps a transaction will cost before submitting it to the network.
  • A Validator cannot also be a BDS
  • Xian provides access to service nodes free of charge, although this service may be limited in the future, depending on use.

Server Specs

These specs are subject to change depending on network growth & use.

Install Xian & Configure Node ​

Install ​

bash
git clone https://github.com/xian-network/xian-stack.git
cd xian-stack
make setup CORE_BRANCH=<branch-name> CONTRACTING_BRANCH=<branch-name>
# for RCNet, use `make setup CORE_BRANCH=rcnet CONTRACTING_BRANCH=rcnet`
# for Testnet, use `make setup CORE_BRANCH=devnet CONTRACTING_BRANCH=devnet`

Build ​

  • For a Validator / Regular Full-Node
bash
make core-build
make core-up
make init
make configure CONFIGURE_ARGS='--moniker <your-moniker> --genesis-file-name genesis-rcnet.json --validator-privkey <priv-key> --seed-node 188.68.33.32 --copy-genesis'
  • For a Blockchain Data Service Node
bash
make core-bds-build
make core-bds-up
make init
make configure CONFIGURE_ARGS='--moniker <your-moniker> --genesis-file-name genesis-rcnet.json --validator-privkey <priv-key> --seed-node 188.68.33.32 --copy-genesis --service-node'
