Abstract
An unenrolled lightweight node is on a decentralized network with a trusted node and a plurality of peers. The unenrolled lightweight node and the peers run a lightweight blockchain consensus algorithm. The unenrolled lightweight node includes (a) circuitry for storing a token that includes a signature that includes at least a signature of at least a first identifier signed with a private key of the trusted node, the first identifier being associated with a public key of the unenrolled lightweight node, and (b) circuitry for broadcasting a request for blockchain enrollment of the unenrolled lightweight node to the plurality of peers. The authentication request including at least a second identifier that is associated with at least a public key of the unenrolled lightweight node, a signature created with at least the second identifier and a corresponding private key of the unenrolled lightweight node, and the token.
