Hello, at block 1,860,000 expanse will enable the Constantinople EIP's, as well as XIP3 (our new name for expips).

XIP3 is similar to XIP2 where we reduced the duration Limit to 30 seconds from 60 seconds. In XIP3 we are reducing the duration Limit again from 30 seconds to 15 seconds but this time keeping the block reward at 4 EXP.

The have a 10k EXP bounty for this. The reason I wanted to do a bounty is because last time I attempted this on my own (im terrible at rust) and someone had to help. This shouldnt be too terribly involved.

In our GETH implementation we also added a feature to ignore chain reorgs from synced nodes that are > 50 blocks in the past and dont add any new work. Its a passive feature but if someone could help me implement that into parity it would help keep the geth and parity networks from experiencing chain splits if those conditions were to be met.

This bounty is still open.

Closing issue due to its stale state.
