The application should be multi-threaded at least the initial Sync. The application must parse the **entire** bitcoin blockchain / chainstate db folder. The application needs to extract all BTC Addresses with Balance > 0 in the fastest possible way. These addresses has to fill a List1 ( BlockchainAdresses ) Could be stored in a database to update it later. A second List (MyBTCAdresses) needs to be filled - MyBTCAdresses should be read from a MSSQL or MYSQL DB – take care the table column will contain around 100 Million Datasets. These Table Column will be filled from another App very fast – so count will grow up. If booth Lists are filled they needs to be compared. Maybe with [login to view URL] and GetHashcode for comparing as fast as possible. If BlockchainAdresses holds items from MyBTCAdresses add these Addresses to another List3 The BlockchainAdresses List and MyBTCAdresses needs to be updated – every few Minutes. If Balance in BlockchainAdresses is 0 they don’t have to be in the list, if new Addresses have Balance > 0 add it to the BlockchainAdresses. If List3 Count Changed Do Some Dummywork with it. The App should be a Windows Form App, that keep the User a bit informed about the entire process. MSSQL, MySQL or another DB could be used. Performance its very very important, if you create it – it should handle 30 Million BTC Adresses and 100 Million or more MyBTCAdresses as fast as possible and keep them up to date. - A fully working Visual Studio project coded in C#. - If you find something open source and can refactor it to meet the requirements, that is fine. There are quite a few different Git repos. If you use a Git project be careful if the repo hasn't been committed to in a long time. I need the application to parse the whole blockchain -- including any places where the structure/block size/etc may have changed If you have questions, let me know. I might be missing requirements or may have failed to address something. Happy to discuss higher level questions or technical specifics.

Hello, I am very interested in your project, and ready to provide it. I delivered a very comparable project 3 years ago here, you can check it: "Bitcoin Balance Viewer from blockchain" https://www.freelancer.com/projects/CPlusPlus-Programming-bitcoin/Bitcoin-balance-viewer-from-blockchain/ and Part 2: "Faster Bitcoin balance lookup" https://www.freelancer.com/projects/CPlusPlus-Programming/Faster-Bitcoin-Balance-Lookup/ They were developed using C++ for maximum performance, I can do it in .Net no problems. The main obstacle will be that bitcoin block chain is > 150 GB, it will be hard for me to download that, however, the blockchain format is same for all coins, so I will develop using an altcoin chain, and you will have to work with me testing it on the real blockchain. Please contact for further discussing the project. (I specified a proposed milestone breakdown, but I'm open to adjustments) Best Regards Khaled
