BlockfinBFT — Storecoin’s Leaderless, asynchronous, BFT Consensus Engine


Storecoin is a zero-fee public blockchain that will transform data into programmable money (into datacoins). Storecoin brings scalable and decentralized zero-fee payment base layer infrastructure to the public internet. Coordinated by a decentralized governance of checks and balances, $STORE aims to become the world's reserve, zero-fee cryptocurrency.

Storecoin is secured by Dynamic Proof of Stake (DyPoS) – a new protocol that blends a leaderless consensus algorithm with an equitable economic model whereby all nodes receive a share of every block reward. BlockfinBFT is the leaderless consensus algorithm powering DyPoS.

Why Storecoin?

By 2025, it is estimated that world will emit 175 zettabytes of data, 5x more data than today. The Storecoin public blockchain is enabling data to be transformed into programmable money -- into data-backed tokens called datacoins. Datacoins are the foundation for a new, open computing platform.

Storecoin provides zero-fee payments and p2p cloud computing blockchain for developers to decentralize their app or device's data into the Storecoin tokenized cloud – transforming their data into programmable money (into datacoins). The miners on Storecoin collectively become a decentralized Amazon Web Services by providing compute, storage, and security for both the zero-fee settlement layer and the datacoins mined on top. The STORE token secures and incentivizes this smart contract-powered datacoin economy.

See Storecoin and Storecoin p2p cloud platform for more details.

Why BlockfinBFT?

Blockchain protocols come in two broad flavors -- Proof-of-Work (PoW) and Proof-of-Stake (PoS). See PoW vs PoS for a quick introduction to the two flavors, how they secure the blockchain, and the major differences between them. The blockchains powered by PoW, such as Bitcoin and Ethereum, are highly decentralized by design, but less so in practice due to handful of mining pools controlling majority of the hash power. See Most Cryptocurrencies Are More Centralized Than You Think for a comparison of some of the popular blockchain projects. They are also very inefficient in processing transactions. Any attempt to increase the throughput will result in poor decentralization or complex architecture (such as sharding, off-the-chain transactions, etc.) and any attempt to increase the decentralization results in poor throughput. BlockfinBFT addresses this with an innovative approach that allows parallel block assembly and validation while requiring all validators to participate in the consensus process. BlockfinBFT achieves true decentralization and high throughput. See BlockfinBFT for how it achieves decentralization and high throughput at the same time.

How This Project is Organized?

BlockfinBFT consists of reusable and independently deployable modules. These modules (or components) are composed to build BlockfinBFT consensus engine. Fig. 1 below shows a high level architecture and component structure of BlockfinBFT.

Each component can be upgraded or replaced independent of others, thus allowing for streamlined bug fixes and enhancements.

Storecoin believes in open source development. We use a number of open source libraries and frameworks to build BlockfinBFT, so why not open source BlockfinBFT itself and develop it openly with contributions from the open source community? This approach serves two purposes.

  1. We walk the talk. Decentralization starts with a decentralized, open source developer community.

  2. Improved visibility, transparency, security analysis, and peer reviews.

Not all the modules are developed at the same time. Some are dependent on others, so it makes sense to start with core set of modules and build upon them. New modules are added as and when the dependent modules get ready.

Each module contains an overview of what it is responsible for, how it interacts with other modules, its dependencies, the modules it depends on, the test cases it must fulfill, and the security framework it must be contained in.

Test First Approach

The modules start with a set of test cases that they must fulfill. More test cases may be added along the way as more use cases are discovered. Initially, all the test cases will fail because there is no code written, but as the module development progresses, more and more test cases pass. The test-first approach helps with envisioning the problem domain and what needs to be solved, followed by how it is solved.

How You Can Get Involved?

Each module is developed independently, as described above. Each module can be owned by a small team of developers, who will participate in the design, implementation, testing, support, and other development activities. Along the way, they become part of the Storecoin community. In the immediate future, Storecoin engineers will keep the rights to accept Github pull requests to the project, but as the community evolves, natural leaders evolve, who start owning such responsibilities. Please contact to learn how you can get involved with BlockfinBFT development and the benefits of becoming part of the Storecoin open source development community.
