An independent review of Chromapolis
A Developer Friendly Blockchain Utilizing a Relational Model
Chromapolis is a blockchain project backed by ChromaWay. The idea redefines both the blockchain architecture as well as the programming language to enhance developer experience. Chromapolis is designed to overcome the shortcomings of existing blockchains by providing a smoother integration, better user experience and scalability for greater dApps adoption.
Chromapolis is incorporated in Estonia and is backed by an experience blockchain company, ChromaWay. The company has been in existence since 2014, redefining blockchain technology across both the public and private sectors. Their objective is to accelerate the adoption of dApps by allowing developers to build applications on their platform easily and providing smoother end-user experience with no wait times and no fees. Several limitations they seek to resolve includes:
•Limited network capacity in existing blockchains
•Expensive I/O (Input/Output) operations
•Error-prone programming language
•End-users paying fees for every transaction
•Limitations on indexing data on blockchains
Chromapolis is integrating a relational model that has existed in corporations for decades into blockchain. This will help in the adoption of existing corporations given that SQL has been used for decades.
A total of 1b Chroma tokens will be issued. 15% of the tokens will be sold to investors in a private sale, with 30% (up to 10% per year) reserved for airdrop and promotional purposes. These details are subjected to changes with more information to be released soon.
Commercial & Technical Strategy
Chromapolis is a blockchain that is built utilising an existing framework, Postchain, with a specific focus to create a truly decentralised shared database. Most blockchains that are optimised as payments are not suitable to host dApps. Hence, with Chromapolis, dApps will be able to achieve the scale and adoption that is currently lacking. Several technical features of Chromapolis are:
•Relational model – The database management model that has been in existence the past 5 decades. This model allows Chromapolis to leverage on SQL DBMS (Data Base Management System) to deploy complex indexing and querying methods without losing throughput.
•Horizontal Scaling – Postchain allows for the creation of multiple blockchains, which are operated by corresponding nodes, which ignites scalability with an increase in total throughput
•RELL – The new programming language developed for Chromapolis that is safer and 7x more efficient than SQL. RELL is concise, expressive and convenient.
•High I/O throughput – Data queries and updates are optimised through a relational database, resulting in higher processing performance
•Chromapolis Consensus – a PBFT-like consensus algorithm anchored with blocks on a PoW blockchain. This mechanism captures both benefits of fast transaction time and improved security strength within the network
•dApss customizability – The flexibility to allow developers to implement various token usage policies that suits the needs of their dApps
The roadmap presented by the team was very brief and is subjected to changes. Here, we cite some significant developments:
•Jul 2018 – Private sale to investors
•Sep 2018 – Testnet Launch
•Oct 2018 – MVP release and TGE
•Feb 2019 – Chromapolis v 1.0 (decentralised governance, support for business applications, custom DB implementation)
•Jul 2019 - Chromapolis v 1.1 (dApp Marketplace, dApp templates, parallel processing, automatic sharding)
