    Distributed Trade Hackathon

    Distributed Trade Hackathon Congrats to the winner of the $10,000 Qtum prize at the Distributed Trade Hackathon: D-Rex (Distributed Real-time Energy Exchange). D-Rex creates a marketplace for financiers and providers to issue and purchase electricity futures. By creating a market for microfinancing generation of electricity D-Rex can crowdfund infrastructure to provide electricity for the 1.5 billion people in the world currently without it.

    The prize seems fitting to go to D-Rex since the Hackathon took place at St. Louis’s world-class start-up accelerator venue T-REX. You can check out their project on devpost.

    Thank you to all 15 teams that participated and spent their weekend building on Qtum and other platforms, we hope you had fun.

    Development Updates

    Changes made through this week to the core wallet:

    Bugs fixed: * [EVM/Consensus] Partially fixed a bug where the block gas limit was not completely enforced. A fix for the remaining issue is coming soon

    * [EVM/Consensus] Fixed a bug where multiple gas refunds to the same address and of the same amount could be left out of a block and still be valid, allowing stakers to potentially still gas refunds

    Work completed: * [Build/Documentation] Added instructions for building Qtum on OSX

    * [EVM/Consensus] Changed the EVM blockchain interface so that it behaves the exact same as in Ethereum, making Qtum smart contracts 100% compatible with Ethereum

    * [Consensus] Changed the “VM version” field within transactions to properly use our designed version format, and enforce that the unknown versions are not allowed on the blockchain

    * [P2P] Added several rules for standard transactions, including sane ranges for allowed gas limits, gas price, and VM versions

    * [Consensus] Added a consensus rule that extremely low gas-limit transactions are now allowed on the blockchain. This only affects executions that were not provided enough gas to actually execute anything anyway

    In-progress work and soon to be fixed bugs: * [SSP/Consensus] Final testing and bug fixing in Smart Stake Protocol is nearly complete

    * [DGP/Consensus] Final testing and bug fixing for DGP should be complete next week
