What is the “Pi node” and why do you want to be a super node?
通常提到“节点”，指的是区块链网络中的计算机，包括手机、矿机、台式机和服务器等等。操作一个节点的人可以是普通的钱包用户、矿工和多个人协作。 例如比特币网络，是属于共有链，当我们在自己的已连接到互联网的电脑上运行bit coin程序时，该电脑也就成为比特币网络中的一个节点。
Generally speaking, “node” refers to the computers in the blockchain network, including mobile phones, mining machines, desktops, servers, etc. The operators of a node can be ordinary wallet users, miners and multiple people. For example, bit coin network belongs to the common chain. When we run the bit coin program on our own computer connected to the Internet, the computer will become a node in bitcoin network.
For a public chain like bitcoin, in theory, you can download a complete blockchain, participate in transactions and mining, which is a node. However, in today’s bitcoin, miners, full nodes, lightweight nodes, and even ordinary users may be called nodes in different contexts.
So, what role does the nodes in the blockchain play? Let’s analyze it for you.
In order to confirm the validity of the transaction, bitcoin needs more than one miner in a separate network to process the transaction order, which must be broadcast to the network through the “node”. This is the first step in the transaction processing (blockchain validation).
To fully tap the potential of the network, bitcoin network can not only provide a channel for transactions, but also ensure security. Using randomly selected nodes, the network reduces the problem of two flowers – the possibility that users try to spend the same digital currency twice.
However, bitcoin does not only need nodes, it also requires many fully working nodes – those nodes that have bitcoin core clients and complete blockchain uploaded in a machine entity. The more nodes, the more secure the network.
For example, each node is equivalent to a server. In this P2P network, it must be spread out and finally recorded and stored by most servers before the message is confirmed.
As the node of blockchain, what are its characteristics? Let’s summarize it for you.
1、 With certain storage space
Storage space refers to electronic storage space, including daily TF card, U disk, mobile hard disk and computer.
2、 Connect to the network
Devices that need storage space connect to the network through a network cable.
3、 Visual operation terminal
Mobile phones, iPads and computers are the mainstream visual operation terminals.
4、 Participate in blockchain
It is necessary to run the corresponding program of blockchain in the storage space connected to the network, and trade through the visual shame terminal.
It can be seen that the internal structure of blockchain is quite exquisite, which is the reason for its many subversive features. At present, blockchain technology is still in the primary stage of development. In the future, with the further maturity of technology, the internal structure of blockchain will be more refined with a wider application range.
But to become a super node, the threshold is not low;
Some super nodes may need to mortgage a certain amount of tokens. For example, PI super nodes are likely to adopt this method. Tens of thousands or even hundreds of thousands of PI coins can be mortgaged to qualify for super nodes. This depends on the specific qualifications officially announced in the later stage. At the same time, there will be certain requirements for the software and hardware environment.
For example, EOS super node selection basic standard:
按照 EOS 团队公布的硬件门槛，想要当上节点最少需要达到亚马逊 AWSEC 2 主机 x1.32x large 型，128 核处理器，2TB 内存，2x1920GB SSD，25Gb 带宽。光一台服务器的成本，一年就需要高达 75.9 万人民币。当基于 EOS 的 DAPP 上线之后，因为交易量的提升而带来的网络带宽成本也将上升。
According to the hardware threshold announced by the EOS team, if you want to be the upper node, you need at least to reach the Amazon AWS EC 2 host x1.32x large, 128 core processor, 2TB memory, 2x1920gb SSD, 25gb bandwidth. The cost of a single server alone is as high as 759000 yuan a year. When DAPP based on EOS goes online, the cost of network bandwidth will also increase due to the increase of transaction volume.
At present, there are hundreds of thousands of PI coin nodes tested and installed in the world. The competition in the future should also be fierce. We will see the specific conditions;
