The Problems

As a payment system, the solution must be equal to or better than Paypal, Visa and Alipay in terms of scalability and cost-performance. As a decentralized market and exchanges, the solution has to be equal to or better than NASDAQ, the New York Exchange in terms of scalability and confirmation speed. As a decentralized supply chain management system, the solution must be applicable on a global scale. As a decentralized E-Commerce solution, the solution must be equal to or better than Amazon and Alibaba by eliminating fees and centralization overhead.

The Solution

Only a solution with a parallelizable architecture and an implementation based on Big Data technology can achieve all of the aforementioned properties at the same time. Without sufficient scalability and cost-performance, a cryptocurrency network cannot achieve ubiquity and become standard.

BigTangle is a cryptocurrency network extending directed acyclic graph architectures with Markov Chain Monte Carlo (MCMC) as a consensus algorithm and distributed Proof-of-Work.

Through the use of industry standard big data technology in conjunction with the parallelizable architecture, BigTangle is a successor to conventional blockchains in the sense that it generalizes existing blockchain and smart contract architectures and makes them usable on a global scale.

BigTangle focuses on economically important key use cases. Custom token issuances, market exchanges, mining and smart contracts are supported. BigTangle is very similar to family trees with MCMC as natural selection process.

The application is built on microservices and is very easy for use. Because of the unique design, BigTangle has the potential to exist as the only platform of its kind, comparable to the Internet.

The Advantages

The BigTangle is a decentralized cryptocurrency, payment, exchange, supply chain and e-commerce platform with the advantages: Near-Time Transactions , Infinite Scalability, Smart Contracts, Permissionless, Trustless, Decentralized Exchange, Ease of use, Completely Feeless and Quantum Security.

BITCOIN, ETHEREUM and IOTA are special cases in BigTangle.

Intrinsic Values of BigTangle!

Worldwide, there are $180 trillions worth of payments made every year, with a combined cost of more than $1.7 trillions a year for processing alone. BigTangle is the only token for enterprises and banks with the ability to facilitate the transfer of values on a global scale. By combining scalability, zero fees and decentralization, it becomes possible to immensely reduce many of the following infrastructure costs:



By providing scalable infrastructure, BigTangle allows the global transaction volume to be processed in one network. Most importantly, this offers infrastructural cost advantages by eliminating complex, costly processes of traditional payment processing.


Fiat Money

For banks and central banks, the token issuance protocol can be used to issue bank-backed tokens denoting conventional fiat money. Fiat money transactions can then feasibly be processed within seconds on a worldwide scale.



Markets for stocks, bonds etc. can easily be realized by creating new token equivalents. Companies can publish stocks and use the BigTangle network. The existing stock markets can be fully integrated by using BigTangle as a financial back-end.


Supply Chain

Under the assumption of trustworthy suppliers issuing authenticity tokens, it is trivial to track product authenticity via token transfers. This allows the trustless tracking of inventories in supply chains for consumers and middlemen alike.


Decentralized E-commerce Platforms

All products and services can be tracked on the network, enabling anyone to build decentralized e-commerce platforms.


Micro Transactions

Services can charge payments in microdollar range or via hashing power due to the departure from winner-takes-it-all, allowing for new business models, e. g. online newspapers with alternatives to commercial advertisement.
