Hi! Join our Slack and ask these questions in the channel #fullnode. We have several devs who will be happy to answer such questions.

Please also check out the "for developers" section of the following page:
https://github.com/wavesplatform/Waves/wikiAs for VPS: if you have min. 10k waves you can earn money with our LPoS by running a full Waves node.
Two questions to Waves team.
Is there an API I can access to retrieve data from the blockchain? I could not find any documentation on the web. Usually, most blockchain projects offers information about retrieving data using the corresponding API.
Secondly, I have a free VPS and I prefer two blockchain projects in order to host a node. What are the advantages of running a WAVES Node? Are there any bonuses to host a Waves node?
