nodes
2 type of nodes
- full nodes
- light nodes
full nodes
- archival type
- pruned full node
archival
archival full nodes maintain a complete copy of the txn history right from the gensys block to the current one. responsible for enforcing consensys and helping with validating txns.
incase of a failure, the blockchain can be reconstructed while there’s 1 intact archival
- mining nodes
- staking nodes
- authority nodes
- master nodes
mining nodes help with creating new blocks on pow blockchains incentivized by block rewards
staking nodes help with validation for new blocks on proof of stake chains
authority nodes are used in partially decentralized networks where these nodes are handpicked by the entity behind the chain
master nodes can’t add new blocks but only validate and keep records of txns
pruned
simply a trimmed down version of an archival full node
download the entire blockchain and verify if it’s correct, then store only the recent block discarding the rest
otherwise they perform the same practices as the other full nodes
lightnodes
enables access to chains for laptops and smart phones
day-to-day blockchain activities like checking balances and broadcasting txns
but dont enforce network consensys
and only store relevant data and rely on fullnodes
eg. bitcoin lightning nodes
