Proof-of-Work is a requirement to define an expensive computer calculation, also called mining, that needs to be performed in order to create a new group of trustless transactions on the distributed ledger or blockchain.
<h3>What is Proof-of-Work in Cryptocurrency?</h3>
- A type of cryptographic demonstration known as proof-of-work involves one party (the prover) demonstrating to another (the verifiers) that a certain amount of computational effort has been put forth.
- Consequently, this spending may be easily verified by verifiers with little work on their behalf.
- The goal of proof-of-work algorithms is not to demonstrate that a task was completed or that a computational challenge was "solved," but rather to prevent data modification by imposing onerous energy and hardware control constraints.
- Environmentalists have criticized proof-of-work systems for using too much energy.
- Later, Bitcoin popularized proof of work as the basis for agreement in a permissionless, decentralized network where miners compete to add blocks and create new money.

Answer:
Total cost of receiving 8000 parts: 2878700
Detailed solution is given in tabular form below:
Answer:
$7,500
Explanation:
Taxable income:
= Income from operations + Dividends received - Expenses from operations
= $200,000 + $15,000 - 140,000
= $75,000
Deductions is allowed only to the maximum extent of 10% of the taxable income of the corporation.
Therefore,
Kingbird's charitable contribution deduction:
= 10% of Taxable income
= 0.1 × $75,000
= $7,500
Answer:
Devil's advocacy.
Explanation:
Devil's advocacy is defined as a person who pretends in a discussion. He/she pretends to be against an idea or plan many people support so as to make people discuss it in more detail. Here Rosana uses devil's advocacy on Henry by telling him to criticize the group's discussion.
