Project overview

PBFT algorithm

In the view numbered VV, one replica node is the primary node and the other replica nodes are backup nodes. The primary node is mainly used to receive the request message sent by the client, which is selEPCed by the formula PP = VMOD | R | = VMOD | R | and | R | is the number of storage replica nodes, Then start the view change, change the current view number VV, and selEPC the master node according to the above formula

Medical blockchain

The pbft algorithm only needs more than four nodes to start. Compared with the blockchain system based on pox algorithm, the block chain system based on pbft algorithm has lower startup cost, is suitable for early exploration and later expansion, and does not need a lot of computing power to maintain. Therefore, this paper will use the pbft consensus algorithm to realize a blockchain suitable for medical system

Foundations of Cryptography

Cryptography is the most important part of a blockchain system, and is the basis of realizing the function of blockchain. The cryptography foundation involved in blockchain mainly includes encryption and decryption algorithm, hash algorithm and digital digest, Merkle tree, digital signature, digital certificate and PKI system

Token issue

Total Issuance

The total issuance will be 1 billion; this total is constant and will never be exceeded. Initially based on ERC20 issuance, it will later develop its own main chain, with ERC20 tokens and main network tokens mapped at a 1:1 ratio.

EPC thinks that the output of mining by uploading data and mining by wisdom medical robot Dpos is 600 million (50% of which are mined by robots and 50% by uploading data)

ICO part: 250 million, the unsold part will be completely destroyed (wisdom medical users participating in ICO can obtain the lease right of wisdom medical robot, the right to obtain psychotropic drugs and the right to reduce medical expenses)

Volumes reserved by the team: 150 million

The part of volumes reserved by the team is allocated as follows:

Foundation 10%: reserved to support the operation of the foundation and to provide the necessary funds for the healthy development of Medical chain (EPC), including audits; consulting, legal and other third-party fees; and other management costs;

Technology development 30%: including costs; general expenses; and expenses dirEPCly attributed to release development, including funding hackathons, rewarding volunteers, and training programmes;

marketing 15%: Including business development; community planning and outreach; related demand survey and analysis; marketing formulation and execution; and other marketing expenses.

Public relations 10%: including public opinion monitoring; investor relationship maintenance; media relationship maintenance; and public relations

Team operation 17%: including the daily development costs of the projEPC.

Dsponsorship 8%: including conferences, research plans, and university outreach

Private investments 10%: early investor work
