People often ask me "How did you learn how to hack?" The answer: by reading. This page is a collection of the blog posts and other articles that I have accumulated over the years of my journey. Enjoy!

The XRP blockchain have a feature called partial payment. This allows a payment to deliver part of what the amount fields says. Why? I'm guessing this is a feature to break up large transfers over time to another user.

When the feature is used, the delivered_amount field contains the actual amount that was delivered. In other cases, the amount contains the full amount of funds that were sent.

In terms of security, they have a hypothetical attack that I felt was interesting. If your sending funds to an exchange, delivered_amount MUST be checked on the transfer. Otherwise, the user will be credited with more funds than they actual sent. An interesting feature that I'm sure has led to problems in the past.
