About Kaspa (KAS)

Layer-1 blockchain

Kaspa (KAS) is a Layer-1 blockchain — a base network with its own consensus, validators, and native coin (KAS) used to pay fees and secure the chain. Developers build applications directly on it, and KAS is the asset that powers the whole ecosystem.

How does Kaspa work?

The Kaspa network is maintained by a distributed set of participants who validate transactions and add them to the blockchain. KAS is required to pay for transactions and, on many networks, to stake and help secure the chain in exchange for rewards.

What is KAS used for?

KAS pays network fees, can often be staked for yield, and serves as the core unit of value across apps built on Kaspa. Demand for KAS tends to track activity and adoption on the network itself.

How a KAS swap works

Enter the amount you want to exchange, pick the asset on the other side, and SwapRocket queries every connected exchange partner at once. You choose an offer, paste the wallet address that should receive the funds, and send KAS to the deposit address shown. The partner executes the trade and pays out to your address — SwapRocket never holds your coins, and there is no account to create before you start.

Choosing a rate for KAS

Three offers are presented for every KAS exchange. The best rate returns the largest amount for the size you entered. The fastest route favours the partner with the shortest expected settlement time, which matters when the market is moving. The fixed rate locks the quoted amount for the duration of the order, so what you are shown is what arrives, at the cost of a slightly smaller payout. Floating offers can move with the market between deposit and settlement.

Networks and addresses for KAS

Kaspa settles on Kaspa. Always send from and to an address on that network: a deposit sent over a different chain cannot be recovered by the exchange partner. When an asset exists on several chains, pick the matching network in the widget before copying the deposit address, and send a small test amount first if you are unsure.

What is KAS? · Sourced guide · Updated 2026-09-24 · 15 sources cited

Kaspa keeps proof of work but replaces the single chain with a blockDAG. How does GHOSTDAG turn parallel blocks into one usable transaction order, and what changes when the network produces ten blocks each second?

Proof-of-work networks face a timing problem: when blocks arrive faster than information can cross the network, honest miners increasingly build at the same time. A conventional longest-chain design eventually keeps one branch and leaves the other block outside the accepted history. Kaspa starts from a different premise. Its ledger is a directed acyclic graph in which a block can reference several earlier blocks, while GHOSTDAG classifies and orders that wider structure. The result is not ten independent ledgers or instant mathematical finality. It is one proof-of-work history assembled from concurrent work, with fast visible confirmations, depth-based confidence and higher operating demands than the original one-block-per-second network.

Keeping parallel work in the ledger

A Kaspa block can point to multiple parent blocks, so two miners that discover valid blocks before hearing from one another do not force the network to discard one immediately. Those references form a blockDAG: edges point backward to known blocks and the graph cannot loop into its own past. Nodes still need a deterministic answer about transaction order, because a payment system cannot leave conflicting spends unordered merely because both appear somewhere in the graph.

GHOSTDAG supplies that answer. The protocol selects a parent, evaluates the merge set around it and classifies blocks into a well-connected blue set and a red set according to a bounded anticone parameter. It then derives a total order from that structure. Red does not mean invalid: valid red blocks remain part of the DAG, but they do not contribute to the selected history in the same way as blue blocks. This is the practical distinction between retaining parallel blocks and pretending every concurrent block can carry equal consensus weight.^{[1], [2], [3]}

Research translated into a running network

The design comes from the PHANTOM and GHOSTDAG paper by Yonatan Sompolinsky, Shai Wyborski and Aviv Zohar. The paper generalizes Nakamoto consensus from a chain to a blockDAG and describes GHOSTDAG as an efficient ordering rule. Kaspa applies that research in public node software. Its current Rust implementation exposes the GHOSTDAG process, validation pipeline and ordering code for review rather than treating the consensus rule as a closed service.

Kaspa preserves other familiar proof-of-work choices alongside the graph. KAS is the native coin of a UTXO ledger, miners perform proof of work to propose blocks, and the project states that mainnet began without a premine or preallocation. Its community-maintained tokenomics record describes an initial reward period followed by the Chromatic Phase, in which the block reward declines monthly by a factor that produces an annual halving. That smooth schedule changes the size of each reward more often than Bitcoin's four-year step, while still making issuance a rule enforced by the network rather than a discretionary payment from an issuer.^{[1], [4], [5], [6]}

Crescendo made ten blocks per second a protocol fact

Kaspa originally operated at one block per second. KIP-14 specified the Crescendo hard fork that raised the target rate to ten blocks per second by reducing the target interval from one second to one tenth of a second. The change activated on mainnet in May 2025 through the Rust node's version 1.0.0 release. Ten blocks per second is therefore a deployed consensus setting, not a projection about future capacity.

The upgrade was more than changing one timer. KIP-14 recalibrated the GHOSTDAG parameter used to tolerate parallel blocks, rescaled time-based consensus values and activated changes intended to manage persistent and transient storage demands. The operator guide raised the recommended processor, memory, storage and bandwidth levels for nodes. Faster blocks can make confirmations visible sooner and spread miner opportunities across more blocks, but the machinery also asks nodes to validate, relay and retain more data in the same wall-clock period.^{[7], [8], [9]}

Fast confirmations are not all the same thing

A newly accepted Kaspa transaction can acquire additional blocks around and after it quickly, but confirmation and finality remain different ideas. GHOSTDAG's ordering is backed by accumulated proof of work and becomes harder to reorganize as blue work grows. Kaspa also implements a finality depth: the protocol rejects a reorganization that would cross the finality boundary rather than silently replacing that established history.

Crescendo's specification set that finality depth to a twelve-hour duration expressed as 432,000 blocks at ten blocks per second. That parameter is a deep protocol safety boundary, not a recommendation that every ordinary transfer wait twelve hours. Wallets, exchanges and swap providers can choose shorter crediting thresholds based on transaction value and their own risk policy. The exact confirmation count used by a receiving service is therefore service-specific and should be checked at the time of transfer.^{[10], [7]}

A native network with its own operational rules

KAS is native to the Kaspa network rather than an ERC-20 token. The maintained wallet documentation provides APIs for creating accounts, deriving addresses, tracking pending and mature balances and submitting transactions against a selected Kaspa network. The reference node and wallet libraries are developed together in the Rust repository, which gives integrators a common implementation for consensus, networking, addresses and wallet operations.

Mining currently uses kHeavyHash, and Kaspa's mining documentation describes both solo and pool participation. Mining equipment and hashrate distribution change over time, so this profile does not freeze a claim about the current share held by a particular device class or pool. Likewise, fees depend on transaction mass and network policy rather than the amount of KAS being transferred. Current fee conditions are UNKNOWN here and belong in a live quote or wallet estimate, not a historical profile.^{[11], [4], [12], [13]}

Scaling the graph without outrunning ordinary nodes

Crescendo demonstrates that Kaspa can move its production network from one to ten blocks per second, but it does not settle every future scaling question. Higher sustained rates increase processing, bandwidth and storage pressure, while pruning reduces how much historical block data a normal node must retain. The long-run shape of node participation under sustained ten-block-per-second use is an empirical question, so it is UNKNOWN rather than assumed from testnet results or hardware recommendations.

The Kaspa Improvement Proposal index also contains ideas for later consensus and programmability changes. Their presence in a repository is not evidence that they are active on mainnet. This profile treats Crescendo as deployed because its specification and release are available, while the timing and final form of proposed successors remain UNKNOWN until an accepted specification and production activation provide direct evidence.^{[9], [14], [15]}

What this means when you hold or move KAS

Send KAS only to a destination that explicitly supports the Kaspa mainnet. A familiar-looking address from Ethereum or another network is not interchangeable with a Kaspa address, and a swap provider may require a particular confirmation threshold before it releases the destination asset. Copy the quoted address exactly, check the named network and use the wallet's current fee estimate rather than relying on an old fixed number.

Frequent blocks can make transfer progress appear quickly, but the receiving service decides when enough proof of work has accumulated for credit. Keep the transaction identifier until the swap finishes, and distinguish a wallet's first confirmation from the provider's completed-order status. Kaspa's block rate changes how often the ledger advances; it does not remove the need to verify the address, network and quoted route before sending funds.
