Bitcoin Gold team finally fixed one of the biggest issues of BTG - according to official Twitter, replay protection is fully implemented.

Bitcoin Gold has just implemented a solution called SIGHASH_FORK_ID replay protection. It is an effective two-way replay protection mechanism that enforces a new algorithm to calculate the hash of a transaction so that all new Bitcoin transactions will be invalid on Bitcoin Gold blockchain and vice versa. This makes replaying transactions impossible.

OKEx reported on the imminent delisting of all Bitcoin Gold (BTG) futures contracts, including weekly, two-week and quarterly contracts. As the reason for this decision, the exchange refers to the “insufficient liquidity” of the financial instrument.

All BTG futures contracts will be calculated on 9am, Jan 25, 2019 (CET, UTC+1) in accordance with the price fixed in the BTG / USD index on OKEx an hour before.

In addition, on January 30, all data on BTG futures trading will be deleted, and therefore the exchange recommends that users who may need this data download them in advance.

Bitcoin Gold separated from the main bitcoin blockchain in November 2017. Last May, the cryptocurrency network was attacked by 51%, during which 388,000 BTG (about $ 18 million) were stolen from several exchanges. Currently, Bitcoin Gold is the 27th largest cryptocurrency with a capitalization of $ 195 million.
