1	NEAR DA Public Blockchain NEAR DA Public Blockchain	There are staked assets on the DA layer that can be slashed in case of a data withholding attack. A dishonest supermajority of validators must collude to finalize a block with missing or invalid data. The invalid block would be added to the chain but rejected by honest full nodes.	There is no fraud detection mechanism in place. A data withholding attack can only be detected by nodes downloading the full data from the DA layer.	No Bridge	N/A	N/A	N/A
2	Meeda Public Blockchain Meeda Public Blockchain	Although node operators are required to stake MEMO tokens to become members of the DA network, there is no slashing mechanism in place for misbehaving nodes.	There is no fraud detection mechanism in place. A data withholding attack can only be detected by nodes downloading the full data from the DA layer.	No Bridge	N/A	N/A	N/A
