The Kaspa ($KAS) blockchain has reached its fifth anniversary. The network launched on November 7, 2021, and has since processed 2.443 billion transactions across 587 million blocks, according to figures shared by the @kaspaunchained account. The network has also recorded 569 thousand wallet addresses.

Few proof-of-work networks launched in 2021 are still operating at this scale after a difficult period for crypto markets. The project's community and ecosystem partners marked the date with anniversary messages on November 7 and 8.

A Fair Launch and a Faster Network

Kaspa describes itself as a fair-launched proof-of-work network.

Mainnet launched in November 2021, with no premine, insider allocation or pre-sales, according to the project's own lore page.
Official project material states that DAGLabs, involved in early research and development, later renounced ownership, transferred the project to the public domain and dissolved.

On the technical side,

Kaspa uses a blockDAG structure rather than a linear blockchain, and its GHOSTDAG consensus protocol orders parallel blocks instead of discarding them

, according to CoinMarketCap's explainer. That design is intended to support faster block production while keeping Bitcoin-style proof-of-work security.

The biggest recent change came with the Crescendo hard fork.

The May 2025 upgrade, which followed a full rewrite of the node software in Rust, raised the block rate to ten blocks per second.
At launch, Kaspa ran one block per second.
Until spring 2025, the network ran at one block per second.

Recent Developments and What Comes Next

Development has continued into the anniversary period.

CoinMarketCap lists a scheduled 5.6% block reward cut on November 5, 2026, as part of the network's monthly emission reduction.
Crypto Ticker reports the reward per block fell from 2.060 to 1.945 $KAS on November 4, 2026.

Dates differ slightly between the two sources.

Ecosystem work is also under way.

Developers published a proof-of-work oracle design on November 3, 2026, aimed at creating Kaspa's first native stablecoin, known as Kaspa Dollar.
Kaspero Labs also released an open-source simulator on November 2 to audit SilverScript contracts before deployment.

Community plans are in place for the milestone as well.

KasMap lists a Kaspa 5th Anniversary Celebration on November 28

, alongside a planned hackathon at EPITA Paris.

Network usage figures such as transaction counts and wallet addresses come from on-chain data and can vary by explorer and counting method. Readers should check them against a block explorer before relying on them.
