Bitcoin Internals, Part 2

In this installment we’ll be talking about Transactions. As we already know a Bitcoin Block contains a Header and a collection of Transactions. We’ve already learned about how important Headers are and how they constitute a back-linked block-chain that helps to maintain the integrity of recorded transactions. Now the two new questions are: What does a Transaction look like? and How do we use it to transfer coins from address to address? And just like in the previous article I’ll be presenting a simplified C++ code here, while the real C++ code will be pointed to via links to Bitcoin’s […]

Thrill – Big Data Processing with C++

Yesterday, I discovered an experimental Big Data processing framework written in C++ called Thrill. As most of you surely know, the well-known frameworks of this kind are mostly based on JVM, like Apache Spark or Apache Flink. This, of course, has many advantages, like easily accessible interfaces and a more domain-oriented approach, as we don’t have to deal with “Ceremony Code” or any internals that don’t touch our domain logic. However, everything comes at a cost and utilizing a VM is a price to be paid no matter how optimized your code is. It’s no wonder these projects often resort to […]
