Liquid users can transact and Peg in assets like L-BTC or issue tokenized assets without depending on centralized intermediaries. https://help.blockstream.com/hc/en-us/articles/900003264706-What-is-a-Liquid-Network-functionary | Yes | Permissioned onboarding is achieved with Blockstream's Asset Management Platform (AMP). AMP enables a user to generate a pseudonymous id associated with their wallet, which can then be used by an issuer to assert a whitelist or blacklist for their specific asset. Whitelists and blacklists are a function of the AMP policy defined by the issuer and does not interfere with the wallet's ability to transact beyond the issuer's asset. https://docs.liquid.net/docs/blockstream-amp-overview | Yes | Yes, Liquid block explorer is available at: https://blockstream.info/liquid | No | Yes | The Liquid Network enables asset issuance using the AMP APIs, which provide advanced asset management capabilities such as freeze and seize properties. These features allow issuers to embed rules into their assets, granting the ability to temporarily restrict (freeze) or reclaim (seize) tokens under predefined conditions, such as for regulatory compliance or risk mitigation. Freeze functionality restricts the movement of specific assets, while seize functionality allows the reallocation of tokens from one address to another. | |||||||||||||||||
