Ecosystem

Projects, tools, and integrations built on Kaspa.

• Are unusual log messages in my Kaspa node a sign of a problem?

  Messages like 'Ignoring duplicate block,' 'missing parents,' 'IDB,' and 'Resolving virtual' in your Kaspa node logs are all normal — they do not indicate errors

• Can I build Kaspa v2.0.0 from source instead of downloading a binary?

  Yes — Kaspa v2.0.0 can be built from source by cloning the master branch of the rusty-kaspa repository and following the build instructions in the README. Build

• Can I change the default port numbers when running a Kaspa node?

  Yes, Kaspa's default RPC and node-to-node ports can both be changed via command-line flags when you start your node. The RPC port is overridden with --rpclisten

• Can I mine Kaspa on a HiveOS rig using community scripts?

  Yes — the Kaspa community has published scripts that run Kaspa mining adapters directly on a HiveOS rig, with support for connecting to either a local Kaspa nod

• Can I reset my Kaspa node's disk usage without losing the network?

  Yes — you can resync a Kaspa node from scratch at any time to bring disk usage back down to around 4 GB. Because the node re-downloads and re-validates the DAG

• Can I run a Kaspa archival node on Windows?

  Yes, Windows is supported, but you will need to enable WSL (Windows Subsystem for Linux) first. The archival node setup requires a command-line tool called rsyn

• Can I run a Kaspa node without --utxoindex if I only want to mine?

  Yes — if your only goal is to mine to the node, you can omit the --utxoindex flag entirely. The --utxoindex flag exists specifically to support wallet operation

• Can I store Kaspa node data on a separate or slower hard drive in Windows?

  Yes — Kaspa's node software (kaspad) lets you choose any folder on any drive for its data, and it does not require a fast SSD. To point kaspad at a differe

• Can I use HiveOS stratum bridge adapters with Kaspa ASIC miners?

  No — the HiveOS stratum bridge adapters covered in community setup guides are not fully compatible with Kaspa ASIC miners, and using them for ASIC mining is not

• Do I need to forward ports on my router to run a Kaspa node?

  Yes — if you want your Kaspa node to accept incoming connections from the internet, you must forward the relevant ports on your home router. By default, routers

• Do I need to use a bootstrap database to sync a Kaspa node?

  No — for most users, bootstrapping the database is almost never justified because syncing a Kaspa node from scratch usually takes about 30 minutes. A bootstrap

• Does Kaspa have a separate node for the TN-11 testnet?

  Yes — as of December 2024, there is a dedicated version of the Rust Kaspa node that is required to participate in the TN-11 testnet. A testnet is a separate, ex

• Does running a Kaspa node require a fast SSD?

  No — storage speed is not a significant factor for running a Kaspa node. Because Kaspa's data flow is slow (on the order of tens of kilobytes per second),

• Does using a DB snapshot speed up Kaspa node synchronization?

  Yes — starting from a database snapshot can reduce the number of synchronization stages your node needs to complete. A full sync from scratch always runs all fi

  An exchange can keep its storage mass low by matching inputs and outputs of similar value magnitude when it builds transactions. Storage mass in Kaspa rises whe

• How can Kaspa mining pools reduce storage mass on their payout transactions?

  A mining pool can eliminate most of its storage mass by setting its cashout threshold higher than a typical coinbase output. A coinbase output is the block rewa

• How did Crescendo affect Kaspa node operators?

  After the Crescendo Hardfork, Kaspa nodes must run P2P protocol version 7 to stay connected to the network. A node is software that participates in the Kaspa ne

  To run a Kaspa archival node, add the `--archival` flag to the start command of the kaspad service after completing the standard node setup. A default kaspad in

• How do I fix a Kaspa node stuck after a database error?

  Navigate to %localappdata%\Kaspad\kaspa-mainnet\datadir2 and delete the newest few files, then restart your node — repeat as needed. Kaspad stores its blockchai

• How do I make sure my kaspad.bat file isn't secretly named kaspad.bat.txt?

  Windows can hide file extensions by default, so a file you name kaspad.bat may actually be saved as kaspad.bat.txt — which will not run as a batch file. To chec

• Where can I learn about mining Kaspa?

  From the KaspaWiki site, "Kaspa is currently only mineable with ASICs. Initially, it was possible to mine it with CPUs and even on mobile devices, and then

  When your Kaspa node starts correctly, it prints a series of log lines to the console confirming the version, database path, and which ports it is listening on.

• How do you change where a Kaspa archival node saves its data?

  You change the data storage location by editing the datadir setting in kaspad's configuration file. Open ~/.kaspad/kaspad.conf in any text editor and find

• How does a Kaspa node discover peers when it joins the network?

  When a Kaspa node connects to a new peer, it immediately requests a list of network addresses so it can find more participants to connect to. Each peer keeps a

• How does Groth16 verification speed affect Kaspa transaction fees?

  Groth16 verification costs more in Kaspa transaction fees because it is approximately 134 times slower than ECDSA signature verification. Blockchain fees are ty

• How does Kaspa activate the new features introduced in KIP-0010?

  KIP-0010's new features switch on once the network crosses a specific DAA score threshold — not a fixed date or block number. Before that threshold, any new opc
