Add header commitments for DAA score, blue work, and finality points (#1817 )

* Add DAAScore, BlueWork, and FinalityPoint to externalapi.BlockHeader.

* Add DAAScore, BlueWork, and FinalityPoint to NewImmutableBlockHeader and fix compilation errors.

* Add DAAScore, BlueWork, and FinalityPoint to protowire header types and fix failing tests.

* Check for header DAA score in validateDifficulty.

* Add DAA score to buildBlock.

* Fix failing tests.

* Add a blue work check in validateDifficultyDAAAndBlueWork.

* Add blue work to buildBlock and fix failing tests.

* Add finality point validation to ValidateHeaderInContext.

* Fix genesis blocks' finality points.

* Add finalityPoint to blockBuilder.

* Fix tests that failed due to missing reachability data.

* Make blockBuilder use VirtualFinalityPoint instead of directly calling FinalityPoint with the virtual hash.

* Don't validate the finality point for blocks with trusted data.

* Add debug logs.

* Skip finality point validation for block whose finality points are the virtual genesis.

* Revert "Add debug logs."

This reverts commit 3c18f519ccbb382f86f63904dbb1c4cd6bc68b00.

* Move checkDAAScore and checkBlueWork to validateBlockHeaderInContext.

* Add checkCoinbaseBlueScore to validateBodyInContext.

* Fix failing tests.

* Add DAAScore, blueWork, and finalityPoint to blocks' hashes.

* Generate new genesis blocks.

* Fix failing tests.

* In BuildUTXOInvalidBlock, get the bits from StageDAADataAndReturnRequiredDifficulty instead of calling RequiredDifficulty separately.

Kaspad

Warning: This is pre-alpha software. There's no guarantee anything works.

Kaspad is the reference full node Kaspa implementation written in Go (golang).

This project is currently under active development and is in a pre-Alpha state. Some things still don't work and APIs are far from finalized. The code is provided for reference only.

What is kaspa

Kaspa is an attempt at a proof-of-work cryptocurrency with instant confirmations and sub-second block times. It is based on the PHANTOM protocol, a generalization of Nakamoto consensus.

Requirements

Go 1.16 or later.

Installation

Build from Source

Install Go according to the installation instructions here: http://golang.org/doc/install
Ensure Go was installed properly and is a supported version:

$ go version

Run the following commands to obtain and install kaspad including all dependencies:

$ git clone https://github.com/kaspanet/kaspad
$ cd kaspad
$ go install . ./cmd/...

Kaspad (and utilities) should now be installed in $(go env GOPATH)/bin. If you did not already add the bin directory to your system path during Go installation, you are encouraged to do so now.

Getting Started

Kaspad has several configuration options available to tweak how it runs, but all of the basic operations work with zero configuration.

$ kaspad
