Do Hyperledger platforms have full/light-weighted nodes like Ethereum?

I'm new to Blockchain and trying to understand if Hyperledger platforms (such as Fabric and Sawtooth) offer full/light nodes separation like Ethereum.

Thanks.

Solution

  • Don't know about STL, but Fabric doesn't have a light node.

    There are 2 reasons for this:

    1) The hash in the block header is simply a concatenated hash over the block data, and not a Merkle tree root. So you cannot prove efficiently that a Transaction exists in a block, without giving the entire block.

    2) Unlike most Blockchains, Fabric is an execute-order Blockchain, which means that some transactions in the block may not be valid at all, and only at the time of commit, the peer checks if they are valid.
