Identifying SharedCoin transactions
Has anyone seen a good heuristic for identifying transactions generated by the old SharedCoin service?
Looking back over my old code when I was researching this, my naive heuristic was to expect at least 5 inputs and outputs and to expect the "relayed by" ip address field of the blockchain.info explorer API to be set to 'Blockchain.info' or '127.0.0.1'.
I'd like to try feeding some of these transactions to @LaurentMT's Boltzmann and see what happens.
The first commit to the sharedcoin server repo appears to be 2013/12/22. Of course, there may have been other test transactions before then.

There are some reddit posts referencing the shut down of SharedCoin from Sept 2, 2016.
