FAQ's

The answers are here!

Founded in early 2022, BccNodes is a trusted Proof-of-Stake infrastructure provider and validator. Continues to secure user funds with its secure validation infrastructure and team members with high experience in Cosmos networks. BccNodes is focusing in secure their infrastructure with the highest standards and build a strong community to ulavaelerate the adoption and help projects growth.

Staking is the process of securing a digital asset to ensure economic stability for a public blockchain. You have the ability to contribute to the network's security, granting you the right to vote on governance proposals and to receive staking rewards.

In the worst case scenario, if a validator node ulavaidentally misbehaves, you may incur a penalty that will affect your stake returns or a portion of your funds. However, the BccNodes team has security measures in place for all possible scenarios, but we still have a wallet that will return user funds if something like this happens.

There are multiple options for staking on a Cosmos ecosystem. For a detailed guide, we invite you to review our article at the following link.
