processes terabytes of data in parallel on a large cluster. Previously, each new distributed system, such as Hadoop and Cassandra, needed to build its own underlying architecture, including message processing, storage, networking, fault tolerance, and scalability. Fortunately, systems like Apache Mesos simplify the task of building and managing distributed systems by providing similar operating system-like management services to key building blocks of distributed systems. Mesos the CPU, storage

In Bitcoin, the lone block has no meaning and will then be discard
