Abstract
In a conversation between a first computing device and a second computing device over a communication channel, each computing device keeps a transcript of the messages that have been sent and received by that computing device. After a threshold number of messages have been sent and received by the devices, each device transmits a summary of the messages sent and received by that device to the other device. If the summaries match, then the messages were sent and received successfully by each device, and the devices can continue to exchange messages until the threshold number of messages is reached again. If the summaries do not match, the devices can roll-back a part of the conversation and the transcript and continue covered by the summaries and continue from there.
