There are different "definitions" published about BlockChain. From our perspective, it is a revolutionary idea, expressed and executed through very simple concepts, therefore, our approach to the "definition" of BlockChain is also very simple:
Drawing an analogy between Ledger model distributed and Manual Ledger, we see that the NODE is the neuralgic piece of the BlockChain Model given that physical infrastructure and chain management reside on it.
Having control of the NODE gives us substantial advantages. The most relevant ones:
It acts as Account Admin, therefore it allows us to control the list of public keys managed by our activity. Although the content is cryptographic and there is no possibility of access, only who has the privilege of Account Admin is the one who can authenticate and therefore sign the transaction. Later the consensus of the Community will be in charge of validating it at time of mining of the Block.
It allows us to run the Ethereum Stat and Ethereum Last Block reports displaying the activity of the filtered BlockChain Network. It means that it offers us the possibility of monitoring the activity of our nodes in a detailed way and being able to deliver the same view to our clients
It allows us to distribute processes between NODES
It approach us to other Deployment Models, because both the PRIVATE and HYBRID models need to be able to create and manage the infrastructure.
