An accessible collection of learning resources.

A library is typically a massive trove of learning resources. It is a collection of diverse materials which serve as foundations and templates for learning or work. In computing, libraries are still collections of learning resources and accessible modules, except that these resources take the form of software documentation, algorithm codes, and sample files for program execution.

There are different library types in computing. Some of these are primarily for learning while others serve as repositories and sharing platforms. However, having access to any of these libraries smoothens the learning curve of programmers and developers.

A type of Layer 2 solution built on top of bitcoin and other existing blockchains to boost system processing.

The Lightning Network is the most popular example of a Layer 2 solution built on bitcoin (and litecoin) for better system processing and scalability. Built over an existing blockchain system, the Lightning Network serves as a complementary framework which allows user transactions to be executed significantly faster than on the original blockchain system. This is because it relies on user-generated channels to increase transactions across involved nodes.

Even though the Lightning Network as a Layer 2 solution is somewhat semi-independent, it still borrows the stability of the underlying system to be effective and relevant.

A physical or digital page-type document for tracking and recording financial transactions.

Ledger is an accounting term that refers to a page-type document that is used to record, track, and manage financial transactions. Traditionally, a ledger is in the form of a book where transactions are meticulously recorded. However, with the computer age came digital ledgers which are in the form of computer files. The latter format is safer, cheaper, and more easily modified on multiple criteria. Moreover, it is far easier to track transactions recorded on computer files than on paper.

The blockchain revolution was initiated on the idea of a digital and distributed ledger. However, the use of the distributed ledger technology (DLT) significantly boosts the functions of a blockchain, rendering it far more useful and versatile compared to an ordinary record-keeping computer file.
