What is proof of work? It may sound complicated, but it actually only involves four elements. The original document, a computer-readable document containing the data, a verifier, and an algorithm that produce the results necessary for the verifier to prove that the data truly exist. Proof of work is sometimes also called “proof of an idea” or “verifiable proof”. It is generally accepted that without such a test people would not be able to guarantee the production of certain tasks, like the production of cash.
The primary function of proof of work (or “proof of idea”) is to provide a method of determining whether a specific computational task was achieved. In a system where computing power is shared among multiple users, a proof of work needs to ensure that the amount of computing power that went into producing the idea was enough to validate the results. Proof of work can also be used to guarantee that work was done by a particular computer system or network. Proof of work can be provided by two methods – one is a finite set of numbers or instructions specifying the completion of a particular algorithm; the other is a mathematical proof that the output is produced by a particular algorithm. The finite set of instructions proof of work can be executed by any number of computers, provided that they all agree to the nature of the instructions.
A second application of proof of work is in the arena of open-source software development. This methodology applies to projects where a group of developers builds and implements a piece of software that creates a physical product – such as a game, widget, or plugin – rather than relying on a proprietary model of development where one team takes credit for the creation of the product. Proof of work enables individuals with little or no computational power to contribute ideas and foster development on a subject that they have an interest in. For instance, if you wanted to create a website based on the world’s most popular languages, you would need to build a piece of code that computes the Fibonacci formula so that anyone can verify the outputs of your website (based on the weights of the nodes in the Fibonacci formula).
One example of using proof of work in the context of the Internet is when someone builds a site with blocks of text based on sentences and words from a dictionary. Rather than looking at the sentences individually, you look at them together as a block. Once you’ve completed this task, the next step is to check each of the blocks to verify whether or not they make sense and that the grammar of the sentence makes sense as well. If they do, the blocks are then inserted into the HTML page as a new element. The proof of work helps prevent errors in copywriting and in fact may even result in your site being banned in certain online communities.
Proof of work can also be applied to the mining industry. As previously stated, a proof of work is an arrangement that a miner puts together before starting their work. This arrangement is made to help ensure that no single entity gains control over the property of the collective. For instance, the first miner that digs a hole in the ground will be the one who gets the property after the initial digging session. The proof of work would ensure that no single entity could control the hole after the mining operation was complete.
In conclusion, proofs of work are not really used in the Internet today because they were difficult to apply in the pre-blockchain times. But that does not mean that they are not useful in the future. In the future, you could imagine a situation where proof of work might be required, for example when certain transactions are done online.
