Jaxx Integration

Qtum is now on Jaxx

Projects are considering making a switch to Qtum

Thanks to a community member on reddit for pointing this small detail about Blocksafe moving to a fork of Qtum. We think that this highlights the power of our technology and hope that more businesses and application developers try out our platform to experience the difference.

Development Updates

Bugs fixed:

  • [Staking/EVM] Fixed bug so that staking checks transaction gas limits at the output level, rather than just the transaction level, preventing certain gas limit exceeding attacks

Work completed:

  • [Misc] Disabled txindex and prune options, since prune is not currently unsupported, and txindex can not be disabled (thanks guest contributor crypt0m1nd3r)
  • [RPC/EVM] Added `getlogs` method to get logs from a specific smart contract for a certain block range
  • [RPC/EVM] Added `getstorage` method to get storage data from a specific smart contract fro a certain block range
  • [Staking] Extended the staker to properly prioritize contract transactions on gas price
  • [Staking] Added options -staker-min-tx-gas-price, -staker-max-tx-gas-limit, and -staker-soft-block-gas-limit for fine tuning acceptable transactions for staking
  • [Consensus] Added a consensus rule to disallow transactions larger than 1Mb

In-progress work and soon to be fixed bugs:

  • We’ve been working on creating a Qtum Ledger (the hardware wallet) app, as well as porting Electrum to work with Qtum. We’ve had some success, but still a ways to go. There is no ETA yet, though we expect it to be done by the time the mainnet is released.
