问题如下：

The process where a node on a blockchain network pledges its digital asset to verify a new block’s validity is called:

选项：

A.tokenization.

B.proof of work

C.proof of stake.

解释：

This proof-of-stake protocol requires selected participants on a blockchain network, the validators, to pledge digital assets to vouch for the block’s validity. This stake signals to the network that a validator is available to verify the veracity of a transaction and propose a block. Other validators who stake a digital asset to the network must then attest to the validity of proposed block. Validators benefit from both proposing and attesting to the validity of blocks that have been proposed by other participants in a similar staking process in the form of new digital assets.
