What is a complete node?

Disclaimer: This section discusses situations applied to the Bitcoin network.

A complete node is any computer connected to the network 24/7 and completely synchronized with it. Full nodes store all blockchain data, starting with the genesis block.

Full Nodes serve the network for free, load and validate each block with transactions, guided exclusively by the consensus algorithm and are completely independent. Full nodes reject the blocks contrary to consensus or individual transactions.

How to install a complete bitcoin-node?

The full node on the bitcoin network can be launched locally on a physical computer or on a virtual server. For launch, you need to download the Bitcoin Core client on the Bitcoin website.Org and upload the entire chain of blocks. An open port of TCP 8333 is needed to work a full node. When using software firewall, you need to provide access to avoid blocking the port.

How the number of complete NDDs affects the functioning of the network?

Owners of full GCD vote for the introduction of new changes in the Bitcoin network. An increase in the number of such nodes favors decentralization and complicates the process of taking protocols only in the interests of certain groups of players.

What is a lightweight node?

Lightened Node is any computer with special software connected to the network of blockchain. Lightweight nodes do not store all blockchain data, but only blocks of blocks to confirm the authenticity of transactions that they contain. The lightweight nodes depend on complete GCDs and can be misleading, confirming transactions that contradict the consensus algorithm.

Is it possible to see a map of full NODs somewhere?

Yes, to see in which geographical points of the planet are currently active nodes of bitcoin on the Bitnodes website. Using this service, you can also check the correctness of port redistribution.

What is a masternoda?

Masternoda is a specially configured complete node that shares a reward for maintenance of the network with miners. The most famous example of the application of masternodes is the Dash network.

Masternodes provide increased anonymity, since information about transactions is not in general access in the blockchain, but is recorded only on masternodes. To start the masternoda, it is necessary to make a fixed deposit with network coins.

What is a supernode?

Super Noda is a master of NEM.

Super Noda is a final point of cryptocurrency APIs without a wallet, public blocks of blocks (according to Ambisafe classification).

What blockchains use the technology of masternodes?

Is it possible to receive income from masternoda?

Yes, the contents of the masternode can be regarded as passive mining, since their owners share profit from generating and validation of blocks with miners. Typically, the profitability of the masternoda is inversely proportional to the liquidity of the coin – in this way, high indicators of capitalization and activity of users determine the decrease in the profitability of the masternoda in such a network.

What services provide information about the profitability of masternodes?

Crypto-Coinz service.NET provides interested users with information about the daily and annual ROI, the price of launching a masternoda (a deposit that needs to be frozen) and the number of GCDs on the network.

What is Harvesting?

This is a way to encourage the NEM https://gagarin.news/ NEM network, which is based on the consensus algorithm Proof-OF-IMPORTANCE (POI). This protocol allows a certain number of Harvet accounts through one client. POI takes into account three factors when determining the account of the significance of the account (the number of coins, the activity of the account in transactions, the time to find the coins on the account), which in turn is the probability of finding the next block with this account (expressed in the semicimilla).

What is local Harvesting?

The launch of local Harvesting is possible only on a local computer, since the NEM customer receives a private key, which jeopardizes the product on the account. This type of Harvesting is the least popular due to safety problems.

What is delegate Harvesting?

This type of Harvesting involves the creation of an intermediary account, whose private key will be transferred to the network client. The intermediary account does not contain funds, which solves the problem of the safety of local Harvesting. Official XEM wallets support only the option of delegated Harvesting.

What is Waves leasing?
