Hello @erric
Welcome to Steemit and the project.hope community
It's always good to see new people, and it's good to have sincerity in being your first publication.
I reviewed your blog, I noticed that you published the same post twice, I found that very strange, it is not advisable to publish the same in two communities, it is frowned upon, but I know that at the beginning of everything it is always very strange, considering that you are new here.
When I use an image, always to place the source. If it's not considered plagiarism, here I leave you a link regarding this topic that is vital in this platform. https://steemit.com/hive-185836/@josevas217/some-important-points-to-avoid-falling-into-plagiarism
I hope it is helpful, not only for images but for texts that are not of your authorship. And even if they are photos of his authorship the best thing is to place the camera or phone used to capture the images
If you have knowledge about blockchain, well, you are in a good place, surely we can learn a lot from you.
It is advisable to always use the introducemyself and introduceyoruself tags for the first publication, and that it be that first one, talking about you, what you hope to get on the platform, etc. As a recommendation.
