* Implement GHOST. * Implement TestGHOST. * Make GHOST() take arbitrary subDAGs. * Hold RootHashes in SubDAG rather than one GenesisHash. * Select which root the GHOST chain starts with instead of passing a lowHash. * If two child hashes have the same future size, decide which one is larger using the block hash. * Extract blockHashWithLargestFutureSize to a separate function. * Calculate future size for each block individually. * Make TestGHOST deterministic. * Increase the timeout for connecting 128 connections in TestRPCMaxInboundConnections. * Implement BenchmarkGHOST. * Fix an infinite loop. * Use much larger benchmark data. * Optimize `futureSizes` using reverse merge sets. * Temporarily make the benchmark data smaller while GHOST is being optimized. * Fix a bug in futureSizes. * Fix a bug in populateReverseMergeSet. * Choose a selectedChild at random instead of the one with the largest reverse merge set size. * Rename populateReverseMergeSet to calculateReverseMergeSet. * Use reachability to resolve isDescendantOf. * Extract heightMaps to a separate object. * Iterate using height maps in futureSizes. * Don't store reverse merge sets in memory. * Change calculateReverseMergeSet to calculateReverseMergeSetSize. * Fix bad initial reverseMergeSetSize. * Optimize calculateReverseMergeSetSize. * Enlarge the benchmark data to 86k blocks.
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.
