On Oct 29th, 1969, two separate points, ARPANET University of California at Los Angeles (UCLA) and Stanford Research Institute (SRI), successfully got connected through cable, signifying the arrival of the Age of Internet. In the last 50 years, with the emergent Internet based companies such as Amazon, Google, Facebook, Alibaba, etc., the information technology proved how it could change the world.

On Oct 31st, 2008, Satoshi Nakamoto presented the idea of Bitcoin in his essay, Bitcoin: A Peer-to-Peer Electronic Cash System, declaring the arrival of value transfer network. Bitcoin impressed the world by its anti-fraud, distributed-ledge, anonymous, and reliable characteristics. However, its performance and PoW (Proof-of-Work) consensus are yet to be improved. In recent years, groups and individuals have engaged in technical innovation on blockchain as trading performance, consensus algorithm and secure anonymity. For example, the Graphene tech and Lightning Network upgraded its performance; Proof of Stake (POS), Delegated Proof of Stake (DPOS) and Practical Byzantine Fault Tolerance (PBFT) were proposed to refine its consensus algorithm; Zero-knowledge proof (ZKP) and mixed-coin tech were expected to enhance security.

Decentralized applications running on blockchains are currently restricted to either being strongly-coupled, such as smart contracts which may only be coded in the blockchain’s language in a limited environment, or weakly-coupled, such as external pseudo-centralized applications which read and write important data to the blockchain as a storage layer.

There is a lot of room between these extremes to be explored, to allow the creation of decentralized applications which leverage the decentralized network of the blockchain and its security properties, while not being bound entirely into a sandbox where each instance merely replicates the results of the others.

The Dencities Project as a whole aim to analyse, experiment, and ultimately develop solutions to these and other problems facing the ecosystem of blockchain technologies. This first version is similar to other existing blockchain technologies but with a few extra key core mechanics which will be leveraged more thoroughly as Dencities progresses into future versions. These core functions bring some unique value to the first version of Dencities but, will deliver vastly more as new functionalities, such as the Dapps platform, geos capability, and infra-chain transactions.
