So, you figured you would like to try getting into blockchain and see for yourself whether it works for you. Now what? If you aren’t dedicated enough to set up your own full node, might be a good idea to use the NOWNodes service to connect to full nodes of some of the most widespread cryptocurrencies. This is a simple and secure way to get into blockchain – but how exactly is it secure?
NOWNodes offers RPC (Remote Procedure Call) connection via which you access the blockchain. This way, you can carry out administrative tasks, control your wallet and obtain the data you need – all via remote procedure calls, or commands you use in the client the cryptocurrency creators provide (almost all of them are BTC-like). For instance, you can use such RPCs, or methods, as GetBlockHash (returns hash of block in best-block-chain at height provided), GenerateToAddress (mine blocks immediately to a specified address (before the RPC call returns)), Ping (requests that a ping be sent to all other nodes, to measure ping time), and many others.
However, not all of the usable remote procedure calls are safe for you and/or other users. Carrying out the “stop” method might lead to undesirable consequences. This is why it is crucial to filter user requests to the node. NOWNodes cares about the customers’ experience and well-being and makes sure to protect their privacy and their funds from any unauthorized third-party intrusions. Every user request is verified by the proxy server first, and if it isn’t suspicious, it gets redirected to the node after that. Moreover, the nodes have a built-in P2P protocol filter, which also helps ensure user safety.
You can find all the necessary documentation on nownodes.io in the respective section. We’ll be adding more information soon, including the methods list and request examples, so stay tuned on Twitter!
While getting introduced to Bitcoin, other cryptocurrencies, or blockchain, in general, might seem a bit difficult and even intimidating at first, a lot of services have been developed over the years, aiming at making the process easier for the new users. NOWNodes by ChangeNOW is one of them: it has been made specifically with this purpose. What exactly does it do? Here is some theory at first.
What is a node in terms of blockchain? Blockchain process can be roughly explained as transferring encrypted data between electronic devices (this process, in turn, is known as transactions) that have an IP address and Internet connection. Basically, each of these devices is a node, the most essential component of the whole process: the nodes support it by having access to a copy of the blockchain. Its structure can be described as a network, namely a P2P (peer to peer) network — it is decentralized, which means that all participants, or nodes, have equal rights.
However, the decentralization doesn’t mean all blockchain nodes are exactly the same. They can be divided into two main categories: full and lightweight nodes. A full node is a device that has 24/7 access to blockchain and stores a complete copy of the whole transaction history. A certain amount of full nodes is crucial for a blockchain network to exist. Lightweight, or light nodes, on the other hand, download only block headers rather than the whole blockchain and are not that important for the blockchain networks to function.
While being significantly easier for the user to run and maintain, light nodes have a number of serious downsides: for example, a user risks to be paid with invalid or fake bitcoins, since light nodes don’t validate cryptocurrency (e.g. bitcoin) rules. User’s transactions can be spied on by a third party. Generally, they are just more vulnerable than full node users. Running the latter guarantees the user won’t face any of these situations. However, not every beginner could be bothered to go all out and run a full node since their first day in the blockchain: it requires time and costs money. And the most important thing is, there is a solution to this problem.
NOWNodes is an innovative service from the creators of ChangeNOW that allows you to connect to the blockchain via a public full node without having to pay a fee. You can choose from a wide range of the most popular cryptocurrencies. The service offers unlimited access to German-located full nodes of these cryptos and claims to provide secure and reliable connection via RPC protocol. NOWNodes has recently announced the launch of supporting the Groestlcoin and Verge full nodes.
The creators of NOWNodes suggest that their service will be of use for young entrepreneurs, students and blockchain beginners, who often have limited resources. Without having to spend anything on running their own full node, they can put their time and money into “making their project the best it can be”. Among NOWNodes’ claimed key features, there are also powerful servers that work non-stop, a high connection speed (1GB per second), and the possibility to start working with the service immediately.
The full list of cryptocurrencies supported by NOWNodes includes Bitcoin (BTC), Ethereum (ETH), DigiByte (DGB), Dogecoin (DOGE), Verge (XVG), Groestlcoin (GRS), ZCoin (ZXC), Bitcoin SV (BSV), and Dash (DASH). The service’s accounts can be found on most popular social media and blogging platforms (Facebook, Twitter, Reddit, Discord, Medium), the SMM management being active and helpful, always ready for feedback. While the platform hasn’t gotten much development yet, it is important to remember it is relatively new — moreover, it has already gained a few positive reviews in the blockchain enthusiast community.
Getting started with NOWNodes is easy: just connect to the full node of your choice and start working. The service claims to offer security and reliability and sounds like a good way to try and find out if you like working with blockchain without having to put much effort into setting up your own cryptocurrency full node.
NOWNodes, an innovative platform that gives its customers unlimited access to major currencies’ full nodes, has an exciting announcement! Today we have started to support the Verge public node.
Verge is an open-source privacy coin. Verge’s mission is to empower people around the world by bringing blockchain transactions into everyday life. NOWNodes is happy to take a part in such a mission by supporting the Verge’s full node so people in the community can use it!
NOWNodes is a project powered by ChangeNOW, non-custodial crypto swaps service. As of right now, NOWNodes supports nodes for four major currencies: BTC, ETH, GRS, and, obviously, XVG!
Our goal is to support much more and we are planning to add several nodes per week.
As for the details on Verge’s node: the servers are located in Germany and the node will be available 24/7: non-stop, fast, and reliable. The connection speed is mind-blowing 1 GB/sec.
