The process by which the state of a blockchain on a particular block height is recorded.

Snapshot refers to the process whereby the state of a blockchain of a particular block height is recorded. It is designed to be used for a specific duration of time. When not properly utilized, snapshots can lead to an excessive accumulation of data, one that tends to get mixed up and eventually becomes useless.

During airdrop events, snapshots serve as tools for recording the balance token of token holders at a particular block height. This ensures that each token holder is verified as being qualified to participate in that distribution round.

The terminology has recently adopted a broader meaning. An exchange can take a snapshot of users at a specific point to decide who gets rewards and in what proportion. A snapshot of token holders is also an important aspect of new token launches on most reliable platforms.

Compiled set of commands written for a computer or software that describes how a program works.

Source code is a compiled set of commands written for a computer or software to work out. The code is written in plain and readable text using a programming language. This programming language is then converted into machine language by a translator, thus enabling the computer or software to perform the written commands.

A source code can be likened to a manual serving as a guide on how the software works. Depending on the kind of software undergoing development, the source code is useful for fixing bug(s) affecting it, thus preventing any further malfunction in the anticipated operations of the software.

A lot of platforms and developers make their source codes proprietary, meaning others don't have access to it. Some release their source codes to the public to facilitate more development or use of a new technology.

An automatic contract in blockchain that confirms a transaction after the stated conditions in the contract are met.

A Smart Contract is an automatic contract on blockchain networks that confirms transactions between sellers and buyers after the stated conditions in the contract have been met. This contract type was initially proposed by Nick Szabo in 1994. The ultimate goal of this proposal was to have contracts whose terms and conditions determined the setting and trust of the parties involved. As a result, buyers and sellers would never have to worry about duplicity. Crypto smart contracts were first used on the Ethereum network. It's now a blockchain staple.

Financial industries stand to gain a lot from the application of smart contracts in their transactions. Also, in crypto, these contracts are proven to be breach-proof, meaning that they offer an extra layer of security for users. Smart contracts launch is usually a significant milestone in a new blockchain's development.
