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!
