What is DV Launchpad?

The vast majority of users who have created validators to date have used the Ethereum 2 Staking Launchpad, a public benefit open source website established by the Ethereum Foundation in conjunction with Obol’s core team. This public-interest open source website tool has achieved great success in the safe and educational creation of large numbers of validators on the Ethereum mainnet.

To facilitate the generation of distributed validator keys among high-trust remote users, Obol Network developed and maintains a website that enables a group of users to come together and create these threshold keys: DV Launchpad. DV Launchpad is a distributed validator launchpad launcher used to bootstrap or create user application interfaces for distributed validators.

#DVT What is the value and significance of encryption technology?

It allows validators to exercise signature responsibilities more stably and securely, and safely assign individual responsibilities to a group.

Suppose you, I, and V God set up a DVT cluster, and we use Coinbase as a backup in case of emergencies. Even if there is a power outage in Singapore where I am, you in Dali and V God in Canada will still have power, and we can rest easy because we are still verifying it.

DVT provides Ethereum with the tools it needs to continue to decentralize, further solidifying its position as a trusted neutrality as the Internet’s settlement layer.

What is #DVT ?

Distributed verification technology, similar to the multi-signature of consensus voting, allows Ethereum PoS validators to be carried out on multiple nodes or machines, so that validators can vote on multiple nodes, supporting Ethereum to verify its distributed operations. The core purpose of technology.

This opens the way for institutional staking, as validators are ensured to meet the higher standards required by institutions. This also democratizes ETH staking, allowing users to run a single validator with less than $32 in ETH.

Simply put, a normal node can be thought of as consisting of consensus and EVM, while a DVT node is composed of multiple consensus and execution clients distributed on multiple machines.

What is #SSV ?

The full name is Secret Sharing Validator. It is a concept proposed by two Ethereum developers, CarlBeek and adiasg, in an article discussing the failure of the ETH2.0 validator.

The core concept 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 discussions and development, SSV was extended and upgraded to DVT. Therefore, SSV is the predecessor of DVT, and SSV is also a Technical term.

#Opclave How to implement biometric identification? Option 3: Apple Secure Enclave

Newer generations of Apple devices feature a hardware security component called a "Secure Enclave" that is capable of storing keys or signature data. The Apple Secure Enclave is a subsystem implemented in Apple's system-on-chip that is isolated from the main processor to create an isolated secure enclave for a user's important data. Its primary use case is to preserve user data even if the main processor is compromised. Transactions can be signed directly using Apple Secure Enclave's signature mechanism. These signatures are then verified in the blockchain and smart contracts through the security step of Face-Id or Touch-Id.

#Opclave How to implement biometric identification? Option 2 Account Abstraction

Opclave has the advantage of a smart contract wallet that is compatible with the ERC-4337 account abstraction standard, providing users with the ability to simplify using their accounts. like:

Can get rid of the constraints of mnemonic words/private keys, etc. Allows users to send bulk transactions. For example, token approval and exchange or claiming and staking operations can be sent in a single transaction. Social recovery mechanisms. You can set up a successor if you have a health issue or if your device is lost. If the wallet does not conduct any transactions for X days, the successor can sign to restore the user's assets. Pay fees using any ERC20 token, currently OP tokens can be used to pay for gas. Daily spending limit. Users can set their daily spending limits to protect against hackers.

#Opclave How to implement biometric identification? Option 1: OP Stack

OP Stack is a set of standardized open source modules that can be assembled into a customized chain - what Optimism calls an "OP chain" - to serve any specific blockchain use case. One of the most important benefits of OP Stack for appchain developers is the simplicity of configuring aggregation and the ability to extend appchain-specific usability without cryptographic economic security.

Using OP Stack, Opclave can implement Apple signatures onto the blockchain, turning Apple devices into hardware wallets.

#ETH #crypto2023 #NFT #Web3

The project #Opclave , which was shortlisted for the ETHGlobal Hackathon, provided a solution:

The core idea is to turn Apple devices, iPhones, and Macbooks into hardware wallets, initiating transactions from the trusted execution environment Apple Secure Enclave to ensure security. This biometric wallet not only simplifies the process of using the wallet, but also migrates the transaction experience from Web2 to Web3, which can increase the number of reuses by users and attract more loyal users.

Current challenges facing the web3 field:

For users who have just entered the Web3 field, creating a wallet may be the first obstacle they encounter. The traditional 12-digit mnemonic phrase is too cumbersome and dangerous for new users. It is also too complex as a backup and recovery function, and has no user experience advantage. At present, no private key and no memorized words are considered to be the mainstream trend of Web3 wallets in the future, but more secure development technology is needed behind this.

In general, #BNB and control of token circulation and flow rate.

In terms of its total economic value, judging from the usage scenarios of BNB, it is related to all parts of the Binance ecosystem. BNB has become the value carrier for asset circulation in the entire Binance ecological economy. From centralized exchanges, DEX, LaunchPad to Binance Chain, etc., they all have their place in capturing value.

In terms of external scenario expansion, there are also BNB usage scenarios in tourism, payment, entertainment and other fields. These scenarios are conducive to increasing demand for BNB.

In addition, BNB tokens are also burned through quarterly patterns and mechanisms to lock BNB in ​​various scenarios, which are conducive to increasing the value of BNB.

#ETH #crypto2023 #NFT #Web3

#BNB Token circulation problem:

The circulation of tokens decreases and the velocity of tokens slows down. BNB is destroyed every quarter until the total amount remains 100 million, which is controlling and reducing the circulation of BNB. In addition, there are many measures to lock tokens in the Binance ecosystem, including holding more than 500 BNB, increasing the commission rate for inviting friends to 40%, participating in the Launchpad project issuance requires holding a certain amount of BNB, and Binance Chain verification nodes need to be locked. A certain amount of BNB, etc., these measures will help slow down the flow rate of BNB.

#ETH #crypto2023 #NFT #Web3

#BNB The impact of ecological application scenarios:

In its ecological application scenario, if the total amount of economic value generated by BNB is greater, then its value will be greater under the same token circulation volume and token flow rate. Therefore, in order to increase the value of BNB, the first step is to expand the total economic value of BNB. The expansion of the total economic value is mainly implemented through the expansion of centralized exchanges, DEX, Binance Chain, external cooperative applications and other scenarios. In-depth exploration of such scenarios will continue. Among them, it is worth noting the futures that Binance is laying out. Due to its user base, the launch of futures will promote Binance’s total economic value.

Total economic value vs. #BNB value

Since Binance has an economic system, the MV=PQ model can be used to evaluate the value of BNB. According to the value model of MV=PQ, the value of a token mainly depends on the total economic value, the actual circulation of the token, and the circulation speed of the token. Among them, the total economic value is positively correlated with the value of the token. The higher the total economic value, the higher the value of the token. There is an inverse relationship between the actual circulation volume of tokens and the circulation velocity of tokens. The greater the actual circulation volume of tokens, the faster the circulation velocity of tokens, and the lower the value of tokens. This is why token deflation and token lock-up can increase the value of tokens.

#BNB Payment scenario:

BNB can book flights and hotels. For example, Australia's TravelbyBit allows users to use BNB to book flights and hotels, and Trip.io can use BNB to book hotels; BitcoinRewards also supports its users to use BNB to purchase on its online store (more than 1,200 worldwide); Trust Wallet is even celebrating the United States On Independence Day, a promotion was held: "Treat guests to beer with BNB." Users downloaded its app and sent their address to receive BNB, which was used to purchase beer.

In addition, live broadcast platform Gifto and VR game platform VIBE can also use BNB for in-app purchases and payments.

Binance Ecological Chain 3. Public chain scenario

As for Binance Chain, the transfer fees for assets on Binance Chain also consume BNB, and nodes producing blocks also need to pledge BNB as proof of equity. The demand for BNB in ​​this scenario is, firstly, related to the transfer scale on Binance Chain. Binance Chain currently has DEX, and its transfer scale currently mainly comes from DEX. The greater the transaction volume on DEX, the higher the transaction volume on Binance Chain. The larger the transfer transaction size, the greater the demand for BNB. If Binance Chain can develop more scenario applications, applications based on Binance Chain may also consume or store BNB, giving BNB a value storage function. Of course, at present, it is mainly based on DEX, and subsequent plans have not been shown yet.

Binance Ecosystem: Capital Issuance Scenario

In terms of capital issuance, Binance Launchpad has a token issuance project every month. Participating users need to hold a certain amount of BNB to be eligible to participate, which will also lead to an increase in demand for BNB.

It also includes blockchain education, blockchain research, blockchain asset information platform, Binance Incubator, and blockchain charity platform.

Binance Exchange Ecological Scenario

BNB has two functions:

1. Use BNB to trade and receive discounts on transaction fees

2. Lock BNB and slow down the flow rate of BNB. In order to obtain transaction fee discounts, users need to lock a certain amount of BNB.

3. If a user holds more than 500 BNB positions, the commission rate for inviting friends will be increased to 40%.
