Look forward to the application scenarios of #DID in the future, it can be simply divided into two categories: Reputation and Relationship.
Reputation can evaluate and classify users by simplifying digital identities into some explicit and trusty labels, so as to do rapid screening. Reputation includes the following application scenarios:
1) #Web3 credit loan: User's address is given a "credit score" which is used to calculate the deductible staking quota in a credit loan.
The “credit score” can be assessed through off-chain identity/asset proof, and the assessment can also include the user's past on-chain transaction records.
2) #Web3 job recruitment: Users can create an on-chain resume to effectively prove their abilities to #Web3 projects/DAO/community, etc., reducing information friction in the process of #Web3 job hunting.
3) #Web3 social networking: Develop the description of user labels, which can depend on the hodling of a specific #NFT. For example, hodlers of @BoredApeYC can be labeled as "rich". Similarly, hodlers of other sorts of #NFT, can also be labeled with different descriptions.
Relationship refers to some more complex and comprehensive applications through the accumulation of user data in #Web3.
1) #Web3 recommendation system: By making use of the user data in #Web3, some platforms will make efforts to form user portraits, and then carry out personalized recommendations and targeted advertisement, etc.
2) #Web3 games: Game developers can build up a game account system (GameID) with the help of user data in the #Web3 game to display the user's interest and ability in the game.
3) #DAO governance: "one person, one vote" fair voting.

#DVT provides an open infrastructure for splitting and distributing validator keys into multiple KeyShares in order to run @ethereum validators on a cluster of nodes, allowing individuals, groups, or communities of operator to form as a single validator.
In the view of technology, #DVT consists of 4 key components: Distributed Key Generation, Shamir Secret Sharing of BLS Signatures, Secure Multi-Party Computation and the #DVT BFT Consensus Layer.
Ethereum will launch the "Shanghai Network Upgrade" in March 2023. What will be changed on @ethereum or, more generally, the #crypto ecosystem with this coming upgrade?
1) What is Shanghai Upgrade?
Conventionally, the upgrade of the @ethereum mainnet is named after the city, such as "London upgrade", "Paris upgrade", etc. The Shanghai upgrade will be another major update of @ethereum.
First, EIP 3540 will be introduced in the Shanghai upgrade will. EIP 3540 is an improved protocol designed to address changes in the Ethereum Virtual Machine Object Format (EOF) separating code from data, which is greatly beneficial to validators on the @ethereum network.
#stETH is a tokenized deposit of staking that can be freely held, traded or sold. Its amount equals to the total amount of staked #ETH plus the total staking rewards and minus service fees.
Cryptoeconomic security has always been a critical challenge for #Web3. As the trailblazer of #crypto, Bitcoin's security model is application-specific, which means any new #dApp needs to build a #blockchain to maintain its own trust network.
@ethereum solves this problem to a certain extent through its modular design. Specifically, the EVM enables #dApps to be built permissionlessly on the @ethereum network by leveraging the underlying security of @ethereum itself, without the need for rebuilding a new trust network
At present, however, middleware and non-EVM applications built on the @ethereum network still need to create their own trust network, but bootstrapping and maintaining the security is expensive and time-consuming, which slows down the speed of potential innovation.
An Ethereum-equivalent ZK-Rollup, also called ZK-EVM, is the holy grail of #L2 scaling solutions because they do not compromise on security or compatibility. Among the many ZK-EVM projects, @Scroll_ZKP is the one that cannot be ignored.
In the current ZK-Rollups technology practices, this solution has an Achilles' heel, which is the lack of #EVM compatibility, causing that all ZK-Rollups have to build unique developer tools and infrastructure from scratch.
In this context, ZK-EVM is considered by many to be the "ultimate game" of #L2 scaling, because it allows ZK-Rollups to integrate the network effects of #EVM while exerting its own performance advantages.
1) #Layer2 separates some functions from #Layer1, which keeps the consensus mechanism that provides security guarantees in #Layer1 and distributes the functions of computation and execution to #Layer2, thus achieving the goal for scaling on the premise of decentralization.
But #Layer2 cannot provide highly customized application scenarios, so here comes #Layer3 which can make up this through customized scaling.
