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.

A capital budgeting project is expected to have the following cash flows: Year Cash Flows 0 -$850,000 1 $300,000 2 $400,000 3 $5
diamong [38]

The capital budgeting project's net present value at an 18% required rate of return is <u>($4,200).</u>

<h3>What is the net present value?</h3>

The net present value represents the net discounted value of cash inflows after subtracting the present value of cash outflows.

The net present value can be determined by determining the present values of cash inflows and outflows and netting the two values.

<h3>Data and Calculations:</h3>

Required rate of return = 18%

Project period = 3 years

Year    Cash Flows    PV Factor        Present Value

0         -$850,000            1                    -$850,000 ($850,000 x 1)

1           $300,000         0.847               $254,100 ($300,000 x 0.847)

2         $400,000          0.718               $287,200 ($400,000 x 0.718)

3         $500,000        0.609               $304,500 ($500,000 x 0.609)

Net present value                                ($4,200)

Thus, the capital budgeting project's net present value at an 18% required rate of return is <u>($4,200)</u>.
