This project is an ongoing exercise to learn about blockchain and cryptocurrencies, and the work is in progress.

Crypto package

The crypto package contains code for generating, signing, and verifying cryptographic keys, as well as signing and verifying signatures. Here are some important details about the package:

• It is written in Go and includes functions for generating public/private key pairs using the Ed25519 algorithm.
• It provides functions for signing messages and verifying signatures using the Ed25519 algorithm.
• It also includes functions for generating addresses from public keys.
• The PrivateKey struct represents a private key, while the PublicKey struct represents a public key.
• The Signature struct represents a signature, and the Address struct represents an address derived from a public key.

Types package

The types package contains code for defining the data types used in a blockchain, as well as some utility functions. Here are some important details about the package:

• It is written in Go and includes functions for hashing blocks and signing them.
• It defines the Block and Header messages using the Protocol Buffers format, which is used to serialize and deserialize data - structures.
• The Block message contains a header and a list of transactions, while the Header message contains the metadata for a block.
• The SignBlock function is used to sign a block with a private key, while the HashBlock function is used to hash a block's header.

Util package

The util package contains some utility functions for generating random data. Here are some important details about the package:

• It is written in Go and includes functions for generating random blocks and hashes.
• The RandomBlock function generates a random block with a random hash.
• The RandomHash function generates a random hash of 32 bytes.

Protocol Buffers file

The block.proto file defines the messages used in the blockchain. Here are some important details about the file:

• It is written in the Protocol Buffers format, which is used to serialize and deserialize data structures.
• It defines the Block and Header messages, which are used to represent a block and its metadata.
• The Transaction message is empty, as it is not used in this implementation.
