  • Gulf Stream: Transfer transaction from clients to Leader Validator
  • Turbine: Transfer messages betwwen validators (Gossip)
  • Crypto Building Blocks (Hash, signature...)
  • PoH
  • Archivers: Store historical data -- Consensus Layer: Tower BFT -- Runtime Layter:
  • Cloudbreak,
  • Pipelining (Solana TPU (transaction per unit))
  • Sealevel -- Application SC Layer: Wallets, Solana Programs

Install Solana (MacOS)

sh -c "$(curl -sSfL https://release.solana.com/v1.14.8/install)"

Verify

solana --version

Useful CLI Commands:

-- Set testnet url: solana config set --url http://api.devnet.solana.com
-- Generate keypair: solana-keygen new --outfile keypair/test-keypair.json -- Set keypair: solana config set --keypair -- Set airdrop: solana airdrop 2 -- Check current public key of current account: solana address -- Check current state of one account: solana account

Install ENV:

-- Set testnet url: solana config set --url http://api.devnet.solana.com
-- Generate keypair: solana-keygen new --outfile keypair/test-keypair.json -- Set keypair: solana config set --keypair -- Set airdrop: solana airdrop 2

Build programs:

• build: npm run build:program-rust
• deploy to devnet: solana program deploy dist/program/helloworld.so
• test program with client: npm start
