* Added model and stubs for all main methods * Add constructors to all main objects * Implement BlockCandidateTransactions * implement expireOldTransactions and expireOrphanTransactions * Rename isHighPriority to neverExpires * Add stub for checkDoubleSpends * Revert "Rename isHighPriority to neverExpires" This reverts commit b2da9a4a00c02fb380d2518cf54fa16257bd8423. * Imeplement transactionsOrderedByFeeRate * Orphan maps should be idToOrphan * Add error.go to mempool * Invert the condition for banning when mempool rejects a transaction * Move all model objects to model package * Implement getParentsInPool * Implemented mempoolUTXOSet.addTransaction * Implement removeTransaction, remove sanity checks * Implemented mempoolUTXOSet.checkDoubleSpends * Implemented removeOrphan * Implement removeOrphan * Implement maybeAddOrphan and AddOrphan * Implemented processOrphansAfterAcceptedTransaction * Implement transactionsPool.addTransaction * Implement RemoveTransaction * If a transaction was removed from the mempool - update it's redeemers in orphan pool as well * Use maximumOrphanTransactionCount * Add allowOrphans to ValidateAndInsertTransaction stub * Implement validateTransaction functions * Implement fillInputs * Implement ValidateAndInsertTransaction * Implement HandleNewBlockTransactions * Implement missing mempool interface methods * Add comments to exported functions * Call ValidateTransactionInIsolation where needed * Implement RevalidateHighPriorityTransactions * Rewire kaspad to use new mempool, and fix compilation errors * Update rebroadcast logic to use new structure * Handle non-standard transaction errors properly * Add mutex to mempool * bugfix: GetTransaction panics when ok is false * properly calculate targetBlocksPerSecond in config.go * Fix various lint errors and tests * Fix expected text in test for duplicate transactions * Skip the coinbase transaction in HandleNewBlockTransactions * Unorphan the correct transactions * Call ValidateTransactionAndPopulateWithConsensusData on unorphanTransaction * Re-apply policy_test as check_transactions_standard_test * removeTransaction: Remove redeemers in orphan pool as well * Remove redundant check for uint64 < 0 * Export and rename isDust -> IsTransactionOutputDust to allow usage by rothschild * Add allowOrphan to SubmitTransaction RPC request * Remove all implementation from mempool.go * tidy go mod * Don't pass acceptedOrphans to handleNewBlockTransactions * Use t.Errorf in stead of t.Fatalf * Remove minimum relay fee from TestDust, as it's no longer configurable * Add separate VirtualDAASCore method for faster retrieval where it's repeated multiple times * Broadcast all transactions that were accepted * Don't re-use GetVirtualDAAScore in GetVirtualInfo - this causes a deadlock * Use real transaction count, and not Orphan * Get mempool config from outside, incorporating values received from cli * Use MinRelayFee and MaxOrphanTxs from global kaspad config * Add explanation for the seemingly redundant check for transaction version in checkTransactionStandard * Update some comment * Convert creation of acceptedTransactions to a single line * Move mempoolUTXOSet out of checkDoubleSpends * Add test for attempt to insert double spend into mempool * fillInputs: Skip check for coinbase - it's always false in mempool * Clarify comment about removeRedeemers when removing random orphan * Don't remove high-priority transactions in limitTransactionCount * Use mempool.removeTransaction in limitTransactionCount * Add mutex comment to handleNewBlockTransactions * Return error from limitTransactionCount * Pluralize the map types * mempoolUTXOSet.removeTransaction: Don't restore utxo if it was not created in mempool * Don't evacuate from orphanPool high-priority transactions * Disallow double-spends in orphan pool * Don't use exported (and locking) methods from inside mempool * Check for double spends in mempool during revalidateTransaction * Add checkOrphanDuplicate * Add orphan to acceptedOrphans, not current * Add TestHighPriorityTransactions * Fix off-by-one error in limitTransactionCount * Add TestRevalidateHighPriorityTransactions * Remove checkDoubleSpends from revalidateTransaction * Fix TestRevalidateHighPriorityTransactions * Move check for MaximumOrphanCount to beggining of maybeAddOrphan * Rename all map type to singulateToSingularMap * limitOrphanPool only after the orphan was added * TestDoubleSpendInMempool: use createChildTxWhenParentTxWasAddedByConsensus instead of createTransactionWithUTXOEntry * Fix some comments * Have separate min/max transaction versions for mempool * Add comment on defaultMaximumOrphanTransactionCount to keep it small as long as we have recursion * Fix comment * Rename: createChildTxWhenParentTxWasAddedByConsensus -> createChildTxWhereParentTxWasAddedByConsensus * Handle error from createChildTxWhereParentTxWasAddedByConsensus * Rename createChildTxWhereParentTxWasAddedByConsensus -> createChildAndParentTxsAndAddParentToConsensus * Convert all MaximumXXX constants to uint64 * Add comment * remove mutex comments
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.
