4. Proof of Work made simple

In this code, a difficulty level is defined (3 in this example). You can submit a random input for the proof of work.

A loop is used to find a valid proof of work by calculating the hash of the input and proof, and checking if it meets the difficulty requirement.

If the hash meets the requirement, the proof is considered valid and the loop is exited. The resulting input, proof, and hash are then output.

The code is here:

5. Ethereum for Developers

Ethereum is NOT a blockchain. It's NOT a cryptocurrency either! It's actually a protocol (a set of rules or procedures) like "HTTP" or "HTTPS".

6. BNB Chain for Developers

BNB Chain is comprised of BNB Beacon Chain, BNB Smart Chain, BNB Sidechain, and BNB ZkRolllup.

7. Avalanche for Developers

Avalanche is a network of networks. It is not a single blockchain running a single, uniform type of blocks. It contains multiple Subnets, each running one or more heterogeneous blockchains.

8. Polygon for Developers

The Ethereum blockchain is slow and costly. Polygon has a bunch of products and services to solve this problem.
