Peer discovery is one of the essential mechanisms in a decentralized network for new nodes to join the network. A blockchain network is a decentralized network with thousands of nodes. And it is not uncommon for nodes to join or leave the network at any time. In this post, we review the peer discovery mechanism in Bitcoin and Ethereum blockchain network in detail. Here, we present the peer discovery protocol in Harmony blockchain based on our current design in the whitepaper.

It is known to maintain records that are growing continuously. These records are called blocks which can be connected securely to each other.

EVM blockchain Aiax Network brings fresh air to the crypto scene, ensuring lower fees

A huge number of such nodes, synchronized with each other through the P2P protocol, ensure that the blockchain functions in a decentralized way without a main process controlling server. Each node is a unit of the system, which is synchronized with the other elements of the system and supports the operation of the entire network. Through the exchange of information between the nodes, transactions are confirmed in the network and the subsequent transfer of information about them. It is the nodes, distributed all over the world, that provide secure transactions and act as the main technology for the movement of funds through the chain. Thus, if one node notices a violation of transaction rules within the system, the transaction is rejected, even if all other communication nodes have confirmed its validity. This structure of distributing communication nodes with equal rights ensures that cryptocurrencies are decentralized and secure. Masternode was developed by Evan Duffield, the creator of the cryptocurrency Darkcoin, which was later renamed Dash.

A node operator runs software that keeps a full copy of the blockchain and broadcasts transactions across the network. Nodes are needed in order to make blockchains work. An operator ensures that nodes run with enough resources to keep nodes stable and performant. Nodes need to have enough RAM, disk space, bandwidth, etc. A masternode is a special type of collateralized and incentivized node that offers additional services to the network in exchange for a portion of block rewards and fees. Examples are anonymous transactions, instant confirmations, file storage, encrypted messaging, etc.
