    Solve problem with Mining Pool 22 hours left

    We have developed a Pool for HyperCash Blake (14r) algorithm that it is running but with errors. The issue is that miners in HyperCash mining mode does not respect/use nonce value in block header. This is miner unique value set by pool, therefor miners are creating same blocks with same hashes at a same time. There is probably some trick how to make miner accept that value. I am looking for someone with experience on blockchain Decreed Coin or HyperCash Coin for guiding us solving the problem.

    I would like a simple set of functions written for trading cryptocurrency in Binance Futures. This needs to be written in C#, and the code must be provided upon completion. The only features I would request: 1. Can connect and stay connected to the Binance Futures API 2. Can place Buy/Sell/SL orders based on some simple input frontend 3. Can read the market in REAL TIME 4. Can trigger adjustments (eg. If Coin reaches X value, change current sell orders to new values) As long as it can do this, I can then adjust the code myself to my exact criteria (outside of your scope).
