Key features, consensus and smart contracts

What decentralisation really buys you, how different chains agree on the next block, and how smart contracts run. You'll find a live Vaulta block producer and trace a contract on an explorer. No account, no money.

• Explain what decentralisation, transparency and immutability give you, and what each one costs.
• Describe proof of work, proof of stake and delegated proof of stake, and the trade-offs between them.
• Explain how Vaulta picks its 21 producers and how Savanna makes blocks final in about a second.
• Find a block producer that's in the top 21 right now on a public explorer.
• Describe what a smart contract is, how one runs, and the questions to ask before trusting one.
