Normaly the nottary node is defined like as shown below in build.gradle file
enter image description here



From above image how do we understand the consensus algorithm of this particular notary?
or from where(which file) we can get information regarding the consensus algorithm of Notary Used?

          All that notary does is check that no states have been spent already when a transaction is sent to it. It does so by storing hashes of spent states and checks that the states in the transaction are not stored in the notary.



          It is not using a consensus algorithm.



          The validating=true is saying that it will execute the contract validation as part of checking the transaction. If that was set to false, it would only check for double spends.

          • @dan-newton That's true, but when you have pools of notaries, they need to use some consensus algorithm to ensure the pool is in agreement about which states are spent.
