Supported Hardware

Swisstronik uses Intel SGX to protect user transactions and smart contract state. Since Intel SGX is a hardware solution, you should have appropriate hardware to run it.

Find supported Cloud Providers and Intel SGX setup instructions at official docs

Hardware requirements

• For now, you can use any Intel CPU which supports SGX via SPS and EPID remote attestation

• 32GB RAM

• 500 GB SSD

Setup validator name

Replace YOUR_MONIKER_GOES_HERE with your validator name

MONIKER="YOUR_MONIKER_GOES_HERE"

Obtain master key

Before starting your node, you should obtain master key, which will be used to encrypt and decrypt transactions and smart contract state.

swisstronikd enclave request-master-key rpc.testnet.swisstronik.com:46789

The command above will pass Remote Attestation, during which, another node checks whether the correct software and hardware are used. If the command returns you same output as shown below, it means your node is ready to work:

[Enclave] Seed successfully sealed
Remote Attestation passed. Node is ready for work

Initialize the node

# Set node configuration
swisstronikd config chain-id swisstronik_1291-1
swisstronikd config keyring-backend test
swisstronikd config node tcp://localhost:17557

# Initialize the node
swisstronikd init $MONIKER --chain-id swisstronik_1291-1
