One of the common requests we have received from our members over the past year has been: in an environment in which there are multiple different blockchains and distributed ledgers in use by various organizations, how can they interoperate?
We took this question and commissioned a paper with Vitalik Buterin who provided a survey of several current and proposed interop solutions. We also asked Nigel King and Ross Nicoll from the R3 London office to put together a short view point and summary of Buterin's survey.
Below are the finished documents originally sent to our members this past September. Distributed got a first look of it a couple weeks ago and put together a short article on the paper as well.
