Implement pruning point proof (#1832)
* Calculate GHOSTDAG, reachability etc for each level

* Don't preallocate cache for dag stores except level 0 and reduce the number of connections in the integration test to 32

* Reduce the number of connections in the integration test to 16

* Increase page file

* BuildPruningPointProof

* BuildPruningPointProof

* Add PruningProofManager

* Implement ApplyPruningPointProof

* Add prefix and fix blockAtDepth and fill headersByLevel

* Some bug fixes

* Include all relevant blocks for each level in the proof

* Fix syncAndValidatePruningPointProof to return the right block hash

* Fix block window

* Fix isAncestorOfPruningPoint

* Ban for rule errors on pruning proof

* Find common ancestor for blockAtDepthMAtNextLevel

* Use pruning proof in TestValidateAndInsertImportedPruningPoint

* stage status and finality point for proof blocks

* Uncomment golint

* Change test timeouts

* Calculate merge set for ApplyPruningPointProof

* Increase test timeout

* Add better caching for daa window store

* Return to default timeout

* Add ErrPruningProofMissesBlocksBelowPruningPoint

* Add errDAAWindowBlockNotFound

* Force connection loop next iteration on connection manager stop

* Revert to Test64IncomingConnections

* Remove BlockAtDepth from DAGTraversalManager

* numBullies->16

* Set page file size to 8gb

* Increase p2p max message size

* Test64IncomingConnections->Test16IncomingConnections

* Add comment for PruningProofM

* Add comment in `func (c *ConnectionManager) Stop()`

* Rename isAncestorOfPruningPoint->isAncestorOfSelectedTip

* Revert page file to 16gb

* Improve ExpectedHeaderPruningPoint perf

* Fix comment

* Revert "Improve ExpectedHeaderPruningPoint perf"

This reverts commit bca1080e7140c78d510f51bbea858ae280c2f38e.

Kaspad

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

ISC License GoDoc

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
