Bitkub Chain launched with a Proof of Authority model run by a small set of known validators, then moved through Proof of Staked Authority with the Erawan upgrade in 2022 and on to a Proof of Stake design. Under Proof of Stake, holders can take part as validators or delegators by staking KUB, and the staked set produces and validates blocks at a target time of about five seconds.

EVM compatibility
Bitkub Chain runs the Ethereum Virtual Machine, so developers can deploy Solidity contracts and reuse Ethereum tooling and wallets with few changes.
KUB token
KUB is the native token. It pays gas fees on the network, is staked by validators and delegators, and is used across applications in the Bitkub ecosystem.
Validators and delegators
Validators stake KUB to produce and verify blocks, while holders who do not run a node can delegate KUB to a validator to share in staking rewards.
Bitkub ecosystem
The chain is built by the Bitkub group and connects to its exchange and consumer products, with KUB used for fees and services across those services.

What is the KUB token used for?
KUB pays gas fees on Bitkub Chain, is staked by validators and delegators to secure the network, and is used across applications in the Bitkub ecosystem.
What consensus does Bitkub Chain use?
Bitkub Chain began with Proof of Authority, moved to Proof of Staked Authority with the Erawan upgrade in 2022, and then to a Proof of Stake design where holders can validate or delegate by staking KUB.
Is Bitkub Chain compatible with Ethereum?
Yes. Bitkub Chain runs the Ethereum Virtual Machine, so Solidity contracts and standard Ethereum tooling and wallets work with few changes.
Can I hold KUB in Zypto App?
Not yet. KUB isn't in Zypto App at the moment. You can hold it in any self-custodial wallet, and you can ask us to add Bitkub Chain using the "Request Bitkub Chain" button above.
