It is more secure (since an attacker with unwanted connection or hacked authority can not overwhelm a network potentially reverting all transactions), less computationally intensive (mining with difficulty which provides security requires lots of computation), more performant (Aura consensus provides lower transaction acceptance latency) and more predictable (blocks are issued at steady time intervals). This makes it easier to maintain a private chain and keep the block issuers accountable.įor consortium setting there are no disadvantages of PoA network as compared to PoW. The chain has to be signed off by the majority of authorities, in which case it becomes a part of the permanent record. It does not depend on nodes solving arbitrarily difficult mathematical problems, but instead uses a set of “authorities” - nodes that are explicitly allowed to create new blocks and secure the blockchain. PoA consensus is reached by referring to a list of validators (referred to as authorities when they are linked to physical entities). The consensus mechanism used in this testchain is Proof of Authority (PoA). The chain keystore in the “devChain” folder contains the keys for the preconfigured account, which is also present in the genesis file “genesis_dev.json”. The preconfigured testnet will start producing blocks inmediately so there is no need to start this manually, for more information check the Proof of Authority section below. There is already a preconfigured tesnet in Nethereum, which can be downloaded from github You might consider using our Creating a new Account using Geth Personal Api document to get a first feel of interacting with Geth using Nethereum. $ geth -rpc -rpccorsdomain " The JSON RPC can also be started from the geth console using the admin.startRPC(addr, port) command.
