tlcc

Trusted Ledger Chaincode (tlcc)

Before your continue here make sure you have built tlcc_enclave. We refer to tlcc_enclave/README.md.

Integrate with Fabric

TLCC is integrated into a fabric peer as system chaincode and thus must be built into the peer binary. We provide a peer target in fabric/ that builds the peer with tlcc integration.

Starting the peer

When starting the peer make sure that LD_LIBRARY_PATH points to the enclave lib.

$ LD_LIBRARY_PATH=$FPC_PATH/tlcc/enclave/lib build/bin/peer node start

Join the channel

This prototype currently supports a single channel only. Start with using configtxgen to create a new channel and let your peer join it. Next, call tlcc (mis)using query operation to join the channel. See example below.

$ bin/peer channel create -o localhost:7050 -c mychannel -f mychannel.tx
$ bin/peer channel join -b mychannel.block
$ bin/peer chaincode query -n tlcc -c '{"Args": ["JOIN_CHANNEL", "mychannel"]}' -C mychannel

Your trusted ledger should be up and running now.

Demo

We have prepared an auction demo script available in fabric/sgxconfig. See start_peer.sh and run_sgx_auction.sh as an example.
