🔺General Blockchain Questions

What is a Layer 1 blockchain?

A Layer 1 blockchain is a standalone network with its own consensus and data layers (e.g., Ethereum, Avalanche, Bitcoin).

What is a permissioned vs. permissionless blockchain?

Permissioned blockchains restrict participation; permissionless ones are open to anyone. Cogitus supports both models for launching your chain using the Avalanche L1 stack.

What is the difference between EVM and custom VMs?

EVM is the standard Ethereum VM. Custom VMs offer specialized logic or performance but may require custom tooling.

What is a validator node, and why is it important?

A validator node confirms transactions and maintains network security by participating in consensus.

What is a blockchain explorer, and how do I use one?

A blockchain explorer lets users search transactions, blocks, addresses, and smart contracts in real-time. All Avalanche L1 chains with Cogitus come with a Block Explorer subscription.

What is gas in blockchain, and how is it calculated on Avalanche?

Gas represents transaction fees. On Avalanche, gas is calculated based on network load and operation complexity.

What is a hot wallet vs. a hardware wallet?

Hot wallets are internet-connected and easier to use. Hardware wallets are offline and more secure.

What is a token bridge, and why does my Avalanche L1 chain need one?

Token bridges allow asset transfer between blockchains. They're essential for liquidity and user access.

What is chain uptime, and why does it matter?

Chain uptime refers to the availability of the network. High uptime ensures reliability and user trust.
