Technical architecture

Complete transparency

Each cryptocurrency transaction is unique, which means it can also easily track through the blockchain higher levels of transparency and public accountability can allay the suspicions of donors, encourage them to give, and improve the reputation of integrity of charities.  

Electronic agreement

Blockchain makes it easier to share and store electronic data and can also be used to ensure that important documents or contracts cannot be modified without the approval of all relevant members.

Globalization and decentralization

Most blockchain networks are highly decentralized, which means they don't need to rely on central management or other institutions, so funds can be transferred directly from donors to charities. In addition, the decentralization of blockchain makes it especially suitable for international transactions.

Reduce the cost

Blockchain technology has the potential to simplify the management of charities, automate some processes and reduce overall costs by reducing the number of intermediaries.

Distributed network

Data must be stored securely, publicly, and redundancy in a distributed network to avoid tampering and single points of failure.

Consensus mechanism

The consensus mechanism adopted by the PWT system is based on DPOS and also USES the system of trustee election, but in the latter part of the algorithm, an optimized PBFT algorithm variant is adopted, which can make loyal nodes agree without bifurcating with O(n^2) message complexity and O(1) time complexity when t < n / 3.

Byzantine fault tolerance

PWT introduces the PBFT(Pratical Byzantine Fault Tolerance) algorithm. The PBFT algorithm also USES round-robin to select the trustor, but instead of creating the block immediately after the trustor is selected, a proposal is first made to determine the next block hash.

Credit system

Trust is established from 0 to 1, regardless of whether it is for donors, third-party charitable organizations or donors. However, such trust often requires a centralized platform or a centralized agent to operate endorsement, so the cost of trust establishment is relatively high.

Service case

Save endangered elephants

Habitat degradation, reduced food supply, illegal hunting... As the largest land wildlife in Asia and the second largest in the world, widely distributed in south and southeast Asia, the Asian elephant has never been in such a difficult situation. Asian elephants have few natural predators. An adult Asian elephant can weigh up to four or five tons, making it the second largest land animal after its relative, the African elephant. But due to illegal hunting and habitat loss, the number of wild Asian elephants on earth has declined rapidly since the 19th century and has been listed as endangered by the international union for conservation of nature (IUCN).
Donor content
To provide funds for the Asian elephant breeding and rescue center to construct the exclusive feeding place of Asian elephant, the agricultural land has been reclaimed by farmers through economic compensation, the original edible plants of wild elephant have been retained, supplemented by artificial planting, and the natural ecology has been restored, so that the released relief elephants can live here and avoid conflicts between human and elephant.

In terms of ecological restoration, besides returning farmland to grassland, banning grazing and emigrating, the livelihood of millions of people has to be solved.

Save the Euphrates poplar forest

Alive millennium is not old, after death millennium do not fall, fell millennium immortality." This is the people's praise of Euphrates poplar, it has amazing drought resistance, sand resistance, salt tolerance, extremely tenacious vitality. Called the "mother river" by the people of all ethnic groups in xinjiang, the tarim river is the longest inland river in China, with a total length of 1,321 kilometers. As an important ecological barrier in the tarim river basin, hu yanglin is called "yingxiong desert". Since the 1950s, the disorderly development and inefficient use of water resources have led to the closure of the tarim river nearly 400 kilometers downstream, the drop in groundwater level and the death of large areas of Euphrates poplar forests.

Reject white pollution

China is the world's largest garbage producer, accounting for 18 percent of the world's population and producing 15 percent of the world's garbage. China has declared war on pollution and wants to develop an ecological civilization. The increased risk of pollution from waste incineration is a byproduct of a new phase of China's economic development. Without development using more environmentally friendly disposal equipment, or does not carry on the public strict recycling education, and in 2013, it is difficult to keep the city clean, shenzhen has established China's first full-time living garbage classification management mechanism, on November 1, 2019, the shenzhen city living garbage classification work incentive measures for the formal implementation in shenzhen. We will help shenzhen set a model for waste sorting in China.
