Final report
The hardfork containing the BSIP-18 implementation paid by this worker was activated today. So far, everything seems to be working as expected.
* People are now able to settle bitAssets that are in black swan state. The first settlement happened soon after the hardfork time, in block http://bitshares-explorer.io:9009/#/blocks/22475777 .
* Some witnesses have reactivated price feeds for most of the bitAssets that were in black swan state. The following assets have been revived instantly after a sufficient number of feeds became available: CASH.USD, GRIDCOIN, HKD, NZD, RUB, SEK, SGD and TUSD. KRW will probably follow soon, it currently has 6 of 7 required feeders.
* GOLOS has enough feeders, but is still waiting for collateral bids.
* It seems to be consensus among witnesses that holders of GOLD and SILVER should be given some time to settle, before price feeds are reactivated. At the current BTS price, SILVER would be revived instantly, while GOLD would require additional collateral.
Unfortunately it seems that @alt hasn't upgraded, as he previously announced. His witness node dropped out immediately after the fork. Please remove your votes.
My work on this has now been completed. I will request payment from the BitShares Foundation.
congrats on the successful HF!
