You don&#x27;t really understand blockchains very well if you think that a trusted party blockchain is vulnerable to defection by one member institution. In fact, they are vulnerable to defection by 1&#x2F;3 of the member institutions (or 1&#x2F;3 of validation power, if you&#x27;re assigning different amounts of validation power to different institutions). Also, a compromise leaves a huge paper trail implicating those responsible.<p>Ripple is overly complicated, includes the XRP currency for the sole purpose of enriching the founders, and has been shown to not be secure on networks larger than one node. There&#x27;s no real reason for a bank to use it instead of just building their own application with the underlying technology. When I see comments like this, I always assume the commenter owns XRP or BTC.
