We have made it available as open source to enable others to explore our architecture and design. IBM's intention is to engage rigorously in the Linux Foundation's [Hyperledger](https://www.hyperledger.org/) project as the community establishes itself, and decides on a code base. Once established, we will transition our development focus to the [Hyperledger](https://www.hyperledger.org/) effort, and this code will be maintained as needed for IBM's use.\n\nWhile we invite contribution to the openblockchain project, we believe that the broader blockchain community's focus should be the [Hyperledger](https://www.hyperledger.org/) project.\n\n# Openchain - Peer\n\nThe steps for running a sample application using this container are described on this page. If you do not have access to a z Systems machine with Linux installed, you can obtain a 90 day __LinuxOne__ cloud instance on the [IBM LinuxONE Community Cloud](https://developer.ibm.com/linuxone/) in just minutes. \n[![LinuxOne](https://developer.ibm.com/linuxone/wp-content/uploads/sites/57/2015/11/linuxone.png)](https://developer.ibm.com/linuxone/) \n\n## Overview\n\nThis project contains the core blockchain fabric. Further information:\n* [Docker for Linux on z](http://www.ibm.com/developerworks/linux/linux390/docker.html)\n\nNotes:\n1. Your firewall rules may require updating to allow traffic on ports 4243, 5000, and 30303\n2. Depending on the number of peers you start you may need to enable memory overcommit: `sysctl vm.overcommit_memory=1`\n\n## Building the project\n\nAssuming you have followed the [development environment getting started instructions](https://github.com/openblockchain/obc-docs/blob/master/dev-setup/devenv.md)\n\n## Testing your container\n\nThis section describes the steps to exercise the container.\n\n### Starting the Daemon\n\nHyperledger interacts with the daemon to create containers on the fly so it needs some specific options when invoked:\n\n```\ndocker daemon -D -g /var/lib/docker -r=true --api-enable-cors=true -H tcp://0.0.0.0:4243 -H unix:///var/run/docker.sock\n```\n\nWhere - \n\nOption | Description\n------- | -------------\n`-D` | Enter debug mode (optional but you get lots of messages)\n`-g /data/docker` | Root of the Docker runtime\n`-r=true` | Restart container if daemon is restarted\n`--api-enable-cores` | Enable cross origin requests\n```-H``` | Daemon socket(s) to connect to\n\n### Starting the First Peer\n\nWe give this peer the id of `vp1`. The `OPENCHAIN_VM_ENDPOINT` environment variable specifies the IP address (referred to later as __) found by issuing (assuming the docker daemon created the `docker0` interface):\n\n```\nifconfig docker0\ndocker0 Link encap:Ethernet HWaddr 56:84:7a:fe:97:99 \n inet addr:172.17.42.1 Bcast:0.0.0.0 Mask:255.255.0.0\n inet6 addr: fe80::5484:7aff:fefe:9799/64 Scope:Link\n UP BROADCAST RUNNING MULTICAST MTU:1492 Metric:1\n RX packets:832417 errors:0 dropped:0 overruns:0 frame:0\n TX packets:1088069 errors:0 dropped:0 overruns:0 carrier:0\n collisions:0 txqueuelen:0 \n RX bytes:197601454 (188.4 MiB) TX bytes:2226944975 (2.0 GiB)\n```\n\nUse this address to start the first peer: \n\n```\ndocker run --rm -it --name=vp1 -e OPENCHAIN_VM_ENDPOINT=http://:4243 -e OPENCHAIN_PEER_ID=vp1 -e OPENCHAIN_PEER_ADDRESSAUTODETECT=true brunswickheads/openchain-peer obc-peer peer\n```\n\nObtain this peer's IP address (referred to later as __) by using:\n\n```\ndocker inspect --format '{{ .NetworkSettings.IPAddress }}' vp1\n```\n\n### Starting the Other Peers\n\nWe can then start 1 or more peers with IDs of `vp2, vp3, ...` in other sessions. The IP address specified in `OPENCHAIN_VM_ENDPOINT` is that (__) and `OPENCHAIN_PR_DISCOVERY_ROOTNODE` is that of the first peer (__). \n\n```\ndocker run --rm -it -e OPENCHAIN_VM_ENDPOINT=http://:4243 -e OPENCHAIN_PEER_ID=vp2 -e OPENCHAIN_PEER_ADDRESSAUTODETECT=true -e OPENCHAIN_PR_DISCOVERY_ROOTNODE=:30303 brunswickheads/openchain-peer obc-peer peer\n```\n\n### Deploying \n\nTo deploy we can start another container and run obc-peer commands.\n\n#### Start a Peer running bash\n\n```\ndocker run --rm -it -e OPENCHAIN_PEER_ADDRESS=:30303 brunswickheads/openchain-peer bash\n```\n\n#### Deploy Chaincode\n\nAt the prompt:\n\n```\nobc-peer chaincode deploy -p github.com/openblockchain/obc-peer/openchain/example/chaincode/chaincode_example02 -c '{\"Function\":\"init\", \"Args\": [\"a\",\"100\", \"b\", \"200\"]}'\n```\n\n\nThen use the `$NAME` (__) it returns to begin querying and invoking chaincode:\n\n```shell\nbash> export NAME1=\nbash> obc-peer chaincode query -l golang -n $NAME1 -c '{\"Function\": \"query\", \"Args\": [\"b\"]}'\nbash> obc-peer chaincode invoke -n $NAME1 -c '{\"Function\": \"invoke\", \"Args\": [\"a\", \"b\", \"3\"]}'\n```\n","has_starred","hub_user","immutable_tags_settings",{"_70":11,"_71":72},"enabled","rules",[73],".*","is_automated","permissions",{"_77":17,"_78":11,"_79":11},"read","write","admin","user","storage_size",1806212473,"orgData","recentTags",[86],{"_87":39,"_88":89,"_90":91,"_92":93,"_94":95,"_45":113,"_114":89,"_115":28,"_116":51,"_52":117,"_118":119,"_120":104,"_121":113,"_122":61,"_123":17},"content_type","creator",496111,"full_size",591354362,"id",2229025,"images",[96],{"_97":98,"_99":100,"_101":102,"_103":104,"_105":106,"_107":102,"_108":102,"_109":-5,"_110":111,"_58":61,"_112":-5},"architecture","s390x","digest","sha256:709ce58497b6d60d54b0434175bff0925d0c8959b176e855f138636dae7fef94","features","","last_pulled","2026-09-13T22:41:43.330774728Z","last_pushed","2016-03-17T14:34:11Z","os","os_features","os_version","size",591354618,"variant","2016-03-17T14:34:11.332454Z","last_updater","last_updater_username","media_type","latest","repository",566490,"tag_last_pulled","tag_last_pushed","tag_status","v2","sbxKitMetadata","isPotentialSpam","isHubSbxKitsEnabled","displaySecurityMetadata","tagAttestations","tagsHaveAttestations",[],"routes/_layout.r.$namespace.$reponame.tags",{"_33":133,"_140":141,"_129":150,"_151":11},{"_35":134,"_37":135,"_40":41,"_42":43,"_44":11,"_45":46,"_47":48,"_49":136,"_52":30,"_27":28,"_53":54,"_55":-5,"_56":57,"_58":59,"_60":61,"_62":-5,"_63":57,"_64":65,"_66":11,"_67":28,"_68":137,"_74":11,"_75":139,"_80":28,"_81":82},[],[39],[51],{"_70":11,"_71":138},[73],{"_77":17,"_78":11,"_79":11},"tags",{"_142":59,"_143":-5,"_144":-5,"_145":146},"count","next","previous","results",[147],{"_87":39,"_88":89,"_90":91,"_92":93,"_94":148,"_45":113,"_114":89,"_115":28,"_116":51,"_52":117,"_118":119,"_120":104,"_121":113,"_122":61,"_123":17},[149],{"_97":98,"_99":100,"_101":102,"_103":104,"_105":106,"_107":102,"_108":102,"_109":-5,"_110":111,"_58":61,"_112":-5},[],"canDeleteTags","actionData","errors"]
