Solana

Chapter 50: Solana Node Setup

Overview

Solana is a high-performance blockchain known for fast transaction processing. It uses a unique Proof of History (PoH) consensus mechanism.

50.1 Solana Basics

Feature	Value
Consensus	Proof of History + Proof of Stake
Block Time	~0.4 seconds
TPS	65,000+ theoretical
Token	SOL

50.2 Hardware Requirements

Component	Minimum	Recommended
CPU	12 cores	16+ cores
RAM	128 GB	256 GB
Storage	1 TB NVMe	2 TB NVMe
Network	1 Gbps	10 Gbps

50.3 Installing Solana

Install CLI

# Install Solana tools
sh -c "$(curl -sSfL https://release.solana.com/v1.18.4/install)"

# Verify
solana --version

50.4 Running a Validator

Initialize

# Create validator identity
solana-keygen new -o ~/validator-keypair.json

# Create vote account
solana-keygen new -o ~/vote-account-keypair.json

Start Validator

solana-validator \
  --identity ~/validator-keypair.json \
  --vote-account ~/vote-account-keypair.json \
  --rpc-port 8899 \
  --entrypoint entrypoint.mainnet-beta.solana.com:8001 \
  --known-validator 7Np41oe9qjpffe7o9f9udmrm9fjn7euhPGXK7x5rVFH \
  --known-validator A1WbuX2JuaA8z6ZcA5J2J9E3vBj9dG5m5K5y5y5y5y5 \
  --limit-ledger-size 50000000 \
  --enable-rpc \
  --rpc-port 8899

50.5 RPC Node Setup

Quick Start

solana-validator \
  --identity ~/validator-keypair.json \
  --rpc-port 8899 \
  --entrypoint entrypoint.mainnet-beta.solana.com:8001 \
  --enable-rpc

Common Commands

# Check cluster health
solana cluster-version

# Get slot
solana slot

# Get block height
solana block-height
