    Varun Srinivasan Retweeted Coinbase

    Excellent work from the @coinbase security team who caught some scary reorgs in ETC. The long-tail of PoW chains will find it hard to protect themselves if inducing reorgs becomes financially profitable. PoW space will likely be dominated by a few, large chains.https://twitter.com/coinbase/status/1082364714246582274 …

    On 1/5/2019, Coinbase detected a deep chain reorganization of the Ethereum Classic blockchain that included a double spend. In order to protect customer funds, we immediately paused movements of these funds on the ETC blockchain.

        If the cost to attack the network is low enough, which in PoW comes down to the cost to RENT more hardware than currently mining 50%, then someone will exploit it...the more chains the easier it becomes because avail power is split. Solution is check-pointing / block finality.

        Like all markets, as crypto matures it will become at least semi-winner take all.
