Dear DeepBrain Chain Community Members,

Please find the latest progress updates below.

1. Technology Development

Gave technical support to ASUS engineers to try out Jupyter notebook on DBC network DBC now supports TensorFlow 13 image Repair partial flaws in core DBC codes Added DBC restful API for task restart

2. Roadmap Goals

For the goals set out in our roadmap for end of June their current progress are as below:



1. Compute power verification: the function of requiring parameters of a miner’s computer power is completed and currently deployed within the network.



2. Support fiat to DBC for compute: DBCTrade website supports fiat purchase DBC token, fiat payment function is completed, however because at the moment DBC token is still based on NEO it is not deployed. Before it is switched to base on DBC’s mainchain we will use the test chain DBC test token to do thorough testing.



3. Server inspection interface: development is near completion, DBC token used to purchase compute power will switch from based on NEO to base on DBC test chain. Testing will continue until DBC main chain launch.



4. Support DBC web wallet: currently, DBC wallet is based on NEO wallets, later we will switch to a wallet that supports DBC main chain’s testnet, once the function is completed we will go into testing. In hindsight we should not have outlined this target as it became clear we were better off just switching with the new test network. However as the test chain light wallet is completed, we can look at integration within the community website very soon.

DBChain, DBCTrade, DBCMiner websites will stay on testing status until DBC’s mainchain launch, once mainnet launch they will run officially.

These websites will function separately to the DBC community website, which will be a combination of all three websites and more, for the purpose of simplicity.

3. Ecosystem Building

A. Compute power provider

Hubei Engineering University: first round live;



B. Compute power purchaser

1. AI Companies

(1)Shanghai Huashan hospital and DeepBrain Chain reached agreement to start using DBC’s compute power Other Channels

(1) ASUS preparing Demo Advance mode & Easy mode for internal presentation, estimated to take 45 working days;

(2)DeepBrain Chain’s Nanchang centre → signing university and cooperation collaboration agreement at Nanchang University;

4. Website Progress

WeChat QR code, Alipay desktop payment API development complete, ready for minor adjustments; Wallet creation: private key generation function, encrypted account generation, and encrypted account export function developed; My wallet: asset balance acquiring and transaction information acquiring developed.

5. Community Governance

We are progressing smoothly with our community consensus and our most recent discussion involved the roadmap and token distribution to our developers. Our closed group has recently reviewed the following core changes:

Token holders as a whole are able to control the development team’s access to funds

Example: “A development team sells 100,000 Tokens for a total of 100,000 ETH.

50,000 ETH will be released from the token contract to the development team immediately, but the remainder is only released once milestones are met, which requires approval of a majority of the token holders each time. If the milestones are never met, the remaining ETH will be used to buy back DBC to be returned to the token holders or burned.”

The exact details of what is to happen with the tokens as well as the transparent and fair review of milestones, is yet to be decided. This will take effect in the beginning of 2020 with community autonomy.

This is significant, as it not only is a show of confidence from the team, but also that it means token holders (supernodes) will have a say in the overall progress of the team and may review how they’re tracking as well as how much value is given to specific targets.

Token holders as a whole are able to vote on significant decisions for the protocol

Example: “Supernode holders may vote on key changes to the protocol, such as burn rate, transaction fees or rewards”

The protocol is a core feature being developed and within it includes many key functions for the operations of the network. As those staking are the ones backing the project, it makes sense for the community to have some involvement with the direction that the developers will take.

These two key points are very important to the utility of the token as well as the integrity of the projects development.

6. Test Chain Progress

The following have been updated since our latest report.

ERC20 standard for smart contracting

ERC20 light wallet interface

Validation and staking testing

Light and full node integration.

It is important to note, DBC is not migrating to Ethereum. However it will be using the same protocol/standard. We are issuing ERC-20 tokens on DBC-MainChain (Parity Substrate) and NOT Ethereum. What does this mean?

By using the same standard, it means that we can use a similar common method for smart contracts and integration that other companies and exchanges are already familiar with using.

The underlying blockchain is Parity Substrate, which DBC-MainChain is based off of. ERC-20 is a technical standard used for smart contracts on the Ethereum blockchain for implementing tokens.

We are merely issuing ERC-20 tokens to users of the DBC-MainChain, by parameters specified. Then building ERC20 standards onto the Substrate code itself as a contract.

The actual backend will handle the staking, etc on the DBC-MainChain (Parity Substrate) and interact with the ERC-20 (DbcErc20) smart contracting system; for exchanges, fiat payment ties and other general tasks involved with a token.
