ArcBlock Blockchain and Dapp Platform
According to a blog post on January 24, 2020, the team says the ArcBlock Token Swap and Asset Chain adopts the "Grayscale" release system. In this protocol, we define authentication as the process that the WALLET provides answers of the requested claims to the DAPP.
(TBD) The trustLevel can be used by the WALLET when displaying requested claims to user. For the DAPP whose appDid cannot be found on registry blockchain, the WALLET should make the entire page with �high risk mark. If an DAPP is asking verifiable claims whose required trust_level is higher than the appDids', the WALLET should display those claims with high risk mark. (TBD) The WALLET could (may under users' request) ask a registry blockchain for the metadata of the DAPP, trustLevel for example.
To read a DID, one just needs to send a GRPC request to ABT network. The structure of the request is described as follows. The keys field is used to fetch specific parts of the state. If it is omitted, entire account states will be returned.
ArcBlock provides ABT chain as a registry chain. ArcBlock is the first blockchain ecosystem for building and deploying decentralized applications that is building the foundation for Blockchain 3.0. ArcBlock is aiming to seamlessly connect the existing system and services, and blockchain networks, throughout dynamic industries.
You are only limited by your imagination. ABT Node is a browser-enabled framework that gives you everything you need to deploy and manage your DApps. It’s flexible, secure, and completely decentralized.
You own everything and its all completely decentralized. The WALLET needs to determine the DID to use to set as the authentication principal. If the user has accessed the DAPP before, then the WALLET should directly use extended DID as the authPrincipal. Otherwise, the WALLET shall create an extended DID before any other operations. Pre-knowledge refers to the process that WALLET gets the information of a DAPP before the real authentication starts.

What is ArcBlock?
DomRaider is launching its token, the DRT, to finance its growth and to propel its blockchain auctions onto a worldwide sphere. - Implement Hyperledger Adaptor with Open Chain Access Protocol. Trading and investing in digital assets is highly speculative and comes with many risks.
If the DAPP did something evil, it will be punished, and its trust level will drop through voting. When see this response, WALLET should prompt the user to sign the agreements. Later, the WALLET should submit a list of signed claim items back to the DAPP. If the user agrees, WALLET shall add the agreed and the sig field.
We're also passionate about developing unique approaches that will significantly advance blockchain development. The World's first blockchain ecosystem for building and deploying decentralized applications. Etherscan Dapp Page enables an easy-to-use and intuitive interface for you to interact with the Smart Contract on the Ethereum Blockchain. When a DAPP wants a user to sign agreements, it should add a list of such claim items in the response.
Trust level is a number to relatively show how trustworthy an DAPP is. The registry blockchain is responsible for maintaining the trust level of an DAPP. For example, an DAPP can stake ABT token on ABT chain to increase its trust level.
With ArcBlock SDK, you can integrate Decentralized Identity into your applications helping your users easily manage their digital properties. A platform to build, manage and deploy the next generation of decentralized applications and blockchain experiences.
A new app that make Token management and accounting easy. Now you've got help to manage your entire token portfolio, transactions and history with meaningful personalized insight. A fully decentralized wallet that put you in control of everything - digital identity, tokens, profiles and more.
- When the DAPP need to guide the WALLET user through a certain business operation, they will probably end up with signing and broadcasting a transaction to the blockchain.
- If it is omitted, entire account states will be returned.
- ArcBlock's primary goal is to remove the barriers that have slowed blockchain adoption among the general public.
- When see this response, WALLET should prompt the user to sign the agreements.
- If an DAPP is asking verifiable claims whose required trust_level is higher than the appDids', the WALLET should display those claims with high risk mark.
This process is irreversible and any transaction that involves a dead account is considered as invalid. ABT DID method defines the DID document as the account state, but one DID does not have a corresponding state in the blockchain state by default. One must declare a DID in order to let it be visible to others on the chain.
ArcBlock Blockchain Monthly Review for November, 2019
ArcBlock's primary goal is to remove the barriers that have slowed blockchain adoption among the general public. Begin accessing DApps and ABT services immediately.
ArcBlock Team To Testify in Support of Blockchain Technologies
The platform goes beyond providing the necessary foundational components for using blockchain to power complex business rules. It connects your existing system to blockchain networks, enabling you to automate business processes using the data and identities associated with existing systems.
Declaring a DID is done by sending a DeclareTx transaction to the blockchain. ArcBlock was born for Blockchain 3.0, it is the world’s first blockchain ecosystem for building and deploying decentralized blockchain applications.
The WALLET shall prompt a user to let him or her to finish this claims and send back to the DAPP again. We will talk about how to process each type claim in next section.
If the user declines, then the WALLET just need to add the agreed field with value false. No signature is required in this situation. An account cannot be erased from a blockchain, but the account owner can send a SuicideTx to mark the account as dead.

DAPP can provide the information in a QR code or deep link. As illustrated in Request DID Authentication step 1, the way of how to generate application-specific DID enforces pseudonymous DID and privacy across different chains. An user has multiple extended DIDs under one master DID and different extended DIDs are used in different chains.
This is the first claim to ask by the DAPP, it is used to informing the WALLET to set the authentication principal for the entire authentication process. The authentication principal is the iss field of the JWT payload sent from the WALLET. So in this example, the DAPP is asking the WALLET to provide some basic information of the user.
The master DID is never exposed publicly in any way. Verify your decentralized ID using the ABT Wallet and secure your node. No longer do you need to rely on 3rd parties, use the ABT Wallet to confirm who you are and who your users are.
