Why Phu Quoc Dog built its own blockchain.

There are some reasons why we are building a separate blockchain network compared to the past.

At the first start in the Phu Quoc Dog project, we created a Token on the Binance Smart Chain (BSC) platform with the aim of taking advantage of BSC’s existing computer networks.

Advantages of using Binance Smart Chain

  • Low transaction fees.
  • Network performance is optimal, can generate each block in just 3 seconds
  • Has a cross-chain Defi mechanism that increases Defi interoperability
  • As an independent blockchain, it is highly secure
  • Interoperability between blockchain and Binance Smart Chain is very good, allowing for chain communication and scaling for dApps

Disadvantages of using Binance Smart Chain

  • After we built a pet social network application that integrates technologies such as IPFS, Network Glossary, Nominators, Identity chains, etc , the implementation in smart contracts on BSC platform is very complicated and there is no high performance
  • No discretion when adding a feature to the BSC network
  • No friendly API to interact with Web 3.0
  • Users who want to buy PQD must have BNB tokens to buy and pay fees.

For all of the above reasons, we decided to build a separate blockchain for the pet social network (Phu Quoc Dog).

We choose Substrate

Substrate is a blockchain framework built by Parity Technologies open-source with RUST language, one of the fastest and lightest programming languages to date. The projects behind it are Polkadot, Kusama, Chainlink, etc. For all information you can refer to this link https://substrate.dev/
As a blockchain 3.0 generation platform with the goal of providing APIs to replace web 2.0, that’s why we chose Substrate to build a private blockchain network.

  • Architected on WebAssembly;
  • Industry Standard Networking Libp2p;
  • Highly scalable;
  • Rust-based primary implementation for speed and reliability. Javascript secondary implementation for development
  • Wasm WebAssembly interpreter, written in Rust.

Substrate is common in most of the Polkadot ecosystems. In addition, our goal is to become a parachain on Polkadot.

So what about the PQD token on BSC?

We will still maintain tokens on the BSC network but we will soon provide you with a bridge to move tokens on the BSC ecosystem to the Phu Quoc Dog Blockchain.

If you are an investor or trader, you can keep the amount of PQD tokens on the BSC platform. However, if you want to use services such as stacking, or running ads, buying NFT on PQD’s mobile application, you must transfer your existing amount of PQD tokens on BSC to Phu Quoc Dog Chain

After we build our own blockchain network, the transaction fee is no longer dependent on BNB, as you know each private blockchain has a transaction fee unit.

For example, on the Ethereum blockchain network. The main unit of charge is Gas. You can find out gas details through this link https://ethereum.org/vi/developers/docs/gas/

The unit of charge in Phu Quoc Dog is Planck

Planck is a physical constant in the universe, if you study physics, the importance of this constant will be important to me. I also graduated with a degree in physics, so I decided to choose this Planck unit as the unit of cost to calculate transaction fee

You can see more at: https://en.wikipedia.org/wiki/Planck_length

In short you can see 1 Planck as same as 1 Satoshis or Wei. In Phu Quoc Dog’s mainnet network

1 PQD = 10000000000 PlanckYou can see the unit summary below.

Development Roadmap

Milestone 1: Implement Substrate And Docs

  • Estimated duration: 1 month
  • FTE: 2
0a.LicenseApache 2.0
0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can (for example) spin up one of our Substrate nodes and send test transactions, which will show how the new functionality works see https://docs.phuquoc.dog
0c.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
0e.ArticleWe will publish an article/workshop that explains on own blog see https://phuquoc.dog/blog
1.Substrate chainUse described modules of our custom chain will provide a token via built-in Proof of Authority (PoA) consensus algorithm , and the block generation algorithm is Aura

Milestone 2: Implement Substrate POS And Governance

  • Estimated duration: 2 months
  • FTE: 2
1Switch the network to PoS modeAfter the network is stable in the PoA stage and there are no visible failures we can switch the network to PoS mode
2Enable governanceThrough the modified BaseCallFilterlogic, the required governance functions can be enabled, including:
3Unit TestsWe will add unit tests to cover mint, burn, transfer, getBalance, getTotalBalance for the basic token.
4TestnetRunning the testnet

Milestone 3: Implement Mobile app and Blockchain Operating System

  • Estimated duration: 5 month
  • FTE: 3
1Build APIBack-end developed in PHP, running on MySQL, Elastic and using Web3js
2Mobile appUI and Mobile app developed in React.js and React native.
3Storage layerStorage protocol layer supports distributed storage of dApp data.
4Substrate WalletsSubstrate Wallets supports blockchain Phu Quoc Dog and Polkadot.

Future Plans

Our first goal is still to develop a pet social network on a private blockchain platform. It will then integrate the NFT feature for each owner’s animal to be unique on the blockchain network.

And finally, we will consider integrating Defi arrays, integrating support for smart contracts from Ethereum’s ERC20 or Binace’s BEP20 platforms that can run on our blockchain.

We know it will take a long time to complete the above ideas, hope you and investors will join us on this path.

Above is our article on why we built a private blockchain network. If you want to have more questions about Phu Quoc Dog, please contact me via email at hello@phuquoc.dog or join the PQD group on Telegram.

Thank you!
