Full Nodes

PoA is the default consensus of Vulcan Blockchain, and validators are responsible to produce blocks and add them to the chain. All Full Nodes make a dynamic validator set where nodes can be added or removed by a voting mechanism where majority (51%) of validator nodes vote to add/remove certain validators, this helps to remove malicious validators while new trusted validators can be added.
Lite Nodes are responsible to elect a set of Full Nodes to participate in each epoch and those elected set of validators take turns in proposing new blocks. The validated block requires a majority of (⅔) must approve the said block. Apart from the elected validator set, there are non-validators who do not participate in block creation but do participate in the block validation process.

🌏 Sentry Nodes (DDOS Protection)

Full nodes are responsible for ensuring that blockchain networks can sustain denial of service attacks which is one of the common attacks performed. To mitigate the risk for validators to carefully structure their network topology in a Sentry Node architecture. These types of nodes can quickly change their IPs and their nature of being in private IP space, these types of attacks cannot affect them directly. This helps validators to propose block and vote without any network interruption. Sentry Node architecture below.

💸 Earning Model

Set of Full Nodes elected by Lite Nodes produce the next block and earn a transaction fee of the validated block. The transaction fee is equally distributed among all the validators in that set. The non-validator set will not get any cut from transaction fee, however they can be elected in the next set to produce a block which occurs every 15 mins.
