About Kaspa

Kaspa origins, the team, and what makes it different.

• Are current blockchains — including Kaspa — vulnerable to quantum computers?

  All current blockchains are quantum vulnerable, with no practical exception yet in mainstream use. A blockchain described as 'quantum vulnerable' is one whose c

• Are existing Kaspa scripts and addresses affected by KIP-0010?

  Existing Kaspa scripts and addresses remain valid after KIP-0010 activates — nothing already on-chain breaks. KIP-0010 adds new opcodes (instructions that scrip

• Are Kaspa's online, KDX, CLI, and paper wallets compatible with each other?

  Kaspa wallets can all send and receive KAS to each other, but online and KDX wallets cannot currently import a seed phrase created by the CLI or paper wallet, a

• Why does Kaspa send my change to a new address instead of the original one?

  When Kaspa returns leftover funds after a transaction, it deposits that change into a freshly generated address rather than back into the address you sent from.

• Why does Kaspa track storage mass and compute mass separately in blocks?

  Kaspa tracks storage mass and compute mass independently because they strain different parts of a node — processing power versus disk space — and lumping them t

• Why does Kaspa use a different hash key for personal message signing?

  Kaspa hashes personal messages with a separate blake2b key — called `PersonalMessageSigningHash` — that is distinct from the `TransactionSigningHash` key used w

• Why does Kaspa use a separate hash key for signing personal messages?

  Kaspa uses two different blake2b hashing keys so that signing a personal message can never accidentally authorize a transaction. When you sign anything in Kaspa

• Why does Kaspa use music terms like 'octave' and 'semitone' in its monetary policy?

  Kaspa's emission schedule borrows its vocabulary from music because the math behind the two is identical. The ratio of block rewards in any two consecutive

• Why does Kaspa use proof of work instead of proof of stake like some other DAG coins?

  Kaspa uses proof of work because it is built as a generalization of the Nakamoto consensus — the same security model that underpins Bitcoin — whereas many other

• Why does Kaspa use two separate mass values for transactions?

  Kaspa measures every transaction against two independent limits — compute mass and storage mass — and uses whichever is larger as the binding constraint. Comput

• Why does Kaspa's actual supply differ from early estimates?

  Kaspa's actual coin supply is roughly 300 million KAS higher than the original estimate because of an early randomized reward period. During the first two

• Why does Kaspa's ASIC mining make the network harder to attack?

  ASICs make attacking the Kaspa network extremely costly because an attacker would permanently destroy their own hardware in the process. An ASIC (Application-Sp

• Why does Kaspa's block validation become harder as block rate increases?

  When Kaspa's block rate increases by a factor of R, the difficulty adjustment algorithm becomes R² times more complex — not just R times. The difficulty ad

• Why does Kaspa's scripting language need 8-byte integer arithmetic?

  KIP-10 adds support for 8-byte integer arithmetic operations to Kaspa's scripting language, allowing scripts to work with much larger numbers than were previous

• Why does Kaspa's storage_mass formula make tiny-UTXO micropayments impractical?

  Kaspa's KIP-9 storage_mass formula charges transactions based on how small their outputs are, making large numbers of tiny UTXOs prohibitively expensive to send

• Why does Kaspa's total supply have a small built-in buffer above the strict schedule?

  Kaspa's DAG structure allows a small number of parallel blocks to be rewarded at a slightly higher rate than the strict monthly schedule, adding a modest b

• Why does Kaspa's total supply look slightly different across explorers and dashboards?

  Small differences in quoted Kaspa supply figures come from the way each node independently tracks the halving threshold, which can introduce a tiny amount of no

• Why does KEF describe Kaspa as a successor to Bitcoin?

  According to KEF, Kaspa represents the next step in cryptocurrency evolution — a true successor to Bitcoin. This is KEF's stated belief, not a universally

• Why does KIP-0010 add support for 8-byte integers in Kaspa scripts?

  KIP-0010 expands Kaspa's scripting system to support 8-byte integers so that scripts can handle large numbers precisely, which is essential for financial calcul

• Why does KIP21 make ZK proving on Kaspa cheaper?

  KIP21's primary goal is to make ZK proving costs proportional to the activity in a relevant lane, rather than the cost of processing the entire network's transa

• Why does my exchange take so long to confirm Kaspa deposits?

  Exchange confirmation requirements are conservative business decisions, not limitations of the Kaspa protocol. When an exchange waits for multiple confirmations

• Why does Proof-of-Work require continuous spending to stay competitive?

  In Proof-of-Work, maintaining influence in the network requires ongoing real-world expenditure on hardware and electricity — there is no passive compounding. A

• Why does proof-of-work use so much energy?

  Proof-of-work (PoW) uses energy as the mechanism that makes transaction ordering permissionless and censorship-resistant. Critics often focus on the cost withou

• Why does Rust's parallelism matter more as Kaspa's block rate increases?
• Why does the Kaspa wallet daemon require the --utxoindex parameter on the node?

  The wallet daemon will refuse to start and show an error if your Kaspa node is not running with the --utxoindex parameter. The UTXO index is a data structure th

• Why does Windows hiding file extensions cause problems when setting up a Kaspa CLI wallet?

  If Windows is set to hide file extensions, a batch file you rename to create-wallet.bat may silently end up saved as create-wallet.bat.txt — and a .txt file can

• Why doesn't Kaspa waste work the way Bitcoin does?

  Kaspa eliminates the wasted-work problem by letting parallel blocks coexist instead of discarding all but one. In Bitcoin, each block can only point to a single

• Why doesn't KDX show my correct balance right away?

  KDX cannot display your correct balance until its built-in Kaspa node has fully synced with the rest of the network. KDX is a "full wallet," meaning i

• Why doesn't proof-of-work allow passive compounding of rewards?

  In proof-of-work, maintaining influence requires ongoing real-world expenditure on hardware and electricity — there is no passive compounding. Unlike proof-of-s

• Why is difficulty adjustment tricky when Kaspa upgrades to 10 blocks per second?

  Upgrading Kaspa's block rate to 10 bps creates a difficulty adjustment problem because the measurement window straddles two different eras. The difficulty adjus

• Why is it hard to reverse a Proof-of-Work transaction?

  Reversing a confirmed Proof-of-Work transaction requires physically redoing the computational work that produced it. That work has a real-world cost — electrici

• Why was Kaspa rewritten in Rust?

  Kaspa was rewritten in Rust to reach maximum efficiency and support higher block and transaction rates. The original codebase accumulated technical debt through

• Why did Kaspa rewrite its node software in Rust?

  Kaspa rewrote its node software in Rust to unlock significant performance gains. The plan moved core consensus logic to Rust first, while external components li

• Why is Kaspa's approach to decentralization different from other DAG projects?

  The level of decentralization in other DAG-based projects is questionable, whereas Kaspa is designed around provable security rooted in the Nakamoto consensus.

• Why is Kaspa's design hard to explain simply?

  Kaspa's theoretical background is genuinely complicated, which makes balancing simplicity and mathematical correctness a core challenge for anyone document

• Why is Kaspa's security formally provable when proof-of-stake coins are not?

  Kaspa's security can be formally proven because its protocol is built on simple, well-understood proof-of-work (POW) principles. Proof-of-stake (POS) is an alte

• Why is raising Kaspa's blocks-per-second rate technically challenging?

  Raising the blocks-per-second (BPS) rate forces a proportional increase in the number of blocks the difficulty windows must track, and that creates a complexity

• Why might a Kaspa wallet refuse to send less than 0.2 KAS?

  Some Kaspa wallets temporarily reject payments below 0.2 KAS because that is roughly the amount at which storage mass approaches the network's standard transact

• Why might my Windows batch file not work after renaming it to .bat?

  If your batch file does not run, Windows may have silently saved it as create-wallet.bat.txt instead of create-wallet.bat. Windows has a setting that hides know

• Why must a full UTXO be spent when sending KAS?

  In Kaspa, a UTXO (unspent transaction output) must be consumed in its entirety — you cannot send only a slice of it. Think of a UTXO like a physical banknote: i

• Why should I check Kaspa mining profitability regularly?

  Mining profitability is not a one-time calculation — it changes continuously, so checking it often is worthwhile. The two biggest moving targets are network has

• Why shouldn't GPU, FPGA, or ASIC miners participate in Kaspa testnet?

  GPU, FPGA, and ASIC miners are asked to stay off the Kaspa testnet to prevent any single miner from capturing too large a share of the network's mining pow

• Why would an attacker prefer GPUs over ASICs when targeting a proof-of-work network?

  An attacker would prefer GPUs because they can be sold or reused after the attack, whereas ASICs cannot. GPUs are general-purpose graphics chips that can mine d

• Why would Kaspa hard-fork or restart testnet 11 instead of just patching it?

  The Kaspa development team suggested hard-forking or fully restarting testnet 11 (TN11) so the finalized rules take effect cleanly, without carrying forward int

• Will Kaspa increase posterity header density in the current KIP?

  No — the current KIP recommends keeping posterity headers at their existing density and deferring any hourly-storage change to a separate follow-up proposal. Th

• Will Kaspa's hard fork affect my balance or require a coin swap?

  No — Kaspa's hard fork will not change your balance, and you will not need to swap, upgrade, or exchange your coins. Some crypto forks require holders to take a

• Will Kaspa's hard fork create two competing coins like a classic split?

  No — Kaspa's hard fork is not expected to produce a second, competing coin. In some blockchains, a hard fork causes a permanent split when miners or developers

• Will KDX's miner work before the node finishes syncing?

  No — KDX's built-in miner will not be functional until the node is fully synced with the Kaspa network. Because KDX contains a complete Kaspa node, both th

• Will KIP-9 require Kaspa wallets, pools, and exchanges to make changes?

  Yes — KIP-9 specifies that ecosystem software such as wallets, pools, and exchanges will need to adapt to the new mass formula. The proposal explicitly describe

• Would Kaspa change its mining algorithm to block ASICs?

  Community discussion on the Kaspa wiki argues that ASIC miners should be welcomed, not blocked through algorithm changes. ASICs are specialized chips built for
