The problem with Lido is the centralization of downstream operators. Because the upstream enters 30% of the POS deposit and then feeds it to the downstream operators, it has very strong control over the operators. The selection and exit of operators are all Lido. I decided on my own. This problem is like the elephant in the room. Everyone has seen it, but because there is no problem yet, everyone chooses to ignore it for the time being. Lido still firmly holds the top spot in POS staking.
In addition, I have said before that stSaaS is equivalent to the operation logic on behalf of you. After you apply for a POS verifier, you give the node key to the operator, and the operator takes your key to help you complete the work of verifying the node. But once Regardless of whether the operator is in terms of stability or deliberately doing evil, the verifier who actually paid the money will be punished. Therefore, the verifier's selection of a reliable operator depends entirely on luck, or in other words, it all depends on Lido's auditing capabilities.
Then the currently proposed solution is DVT decentralized verifier technology, which allows multiple node operators to jointly operate verifiers. The previous verifiers and operators had a 1-to-1 relationship, and DVT is a 1-to-N relationship, so that Reducing single points of failure will not directly affect the corresponding verifiers if an operator fails. If one operator fails, other operators can take over.
The core concept of SSV is to fragment the verifier's private key and give it to multiple operators, which is equivalent to the logic of multi-signature. After continuous discussion and development, SSV was extended and upgraded to DVT, so SSV is the predecessor of DVT. SSV It is also a technical term, and the @ssv_network we are talking about today directly named itself SSV because it is a practitioner of the SSV concept. This is such a relationship.
Therefore, Lido is also aware of its own centralization problem. It is also exploring the effect of integrating DVT solutions to allow operators who have and have not been reviewed by Lido to conduct mixed verification, thereby reducing the risk of centralization of Lido operators. Last year
