Once you obtain these from a separate online computer they will be good for use for the next 64k blocks (or roughly 2.2 days).\n\nThe transaction generated must be broadcast within 1 hour after being created or it will expire.\n\n## Building:\n\n`\ndocker build -t=\"steemit/offline_signing:latest\" .\n`\n\n(alternatively, you can just pull in a pre-built image with `docker pull steemit/offline_signing:latest`)\n\n## Running:\n\n1. On a computer that is online, to collect the necessary recent reference block number and prefix, run:\n\n- `docker run -it steemit/offline_signing:latest`\n\n- Collect the two numbers and save them for the next step.\n\n2. From an offline computer that already has the docker image built and available, run:\n\n- `docker run -it steemit/offline_signing:latest /bin/bash sign_offline_transfer.sh `\n\n- The software will ask for your private key WIF. This can be either your active or owner key private key for a transfer operation.\n\n- Note: the must have a precision of 3 - example: 10 STEEM would be 10.000\n\n- Example of a correct command:\n\n`docker run -it steemit/offline_signing:latest /bin/bash sign_offline_transfer.sh 28468 851006437 alice bob 10.000`\n\n3. Take the generated signed transaction and broadcast it from an online computer. You have 1 hour to complete this before the transaction is expired and is no longer valid. It can be brodcasted simply using `curl`\n\n- Insert the transaction in this command where it says INSERT_TRANSACTION_HERE, leave the brackets around it:\n\n`curl -s --data '{\"jsonrpc\":\"2.0\", \"method\":\"condenser_api.broadcast_transaction\", \"params\":[INSERT_TRANSACTION_HERE], \"id\":1}' https://api.steemit.com`\n\n- Example of fully filled in command:\n\n`curl -s --data '{\"jsonrpc\":\"2.0\", \"method\":\"condenser_api.broadcast_transaction\", \"params\":[{\"ref_block_num\":28468,\"ref_block_prefix\":851006437,\"expiration\":\"2020-01-28T21:45:21\",\"operations\":[[\"transfer\",{\"from\":\"alice\",\"to\":\"bob\",\"amount\":\"10.000 STEEM\",\"memo\":\"\"}]],\"extensions\":[],\"signatures\":[\"1f422e9f579951b9bf8333a9d419ad05dbdd9ac990b8aef5f9ac739ab698a7eef805143d9cdc43df620f15f4de0a06bc90cef3dd5ac07f77050a1c292b719d01f8\"]}], \"id\":1}' https://api.steemit.com`\n\n- A successful submission will return an empty json result, like this: `{\"jsonrpc\":\"2.0\",\"result\":{},\"id\":1}`. If there is an error (such as exceeding the expiration time), you will instead receive that from the node.\n\n4. Verify that the transaction was successful using either a block explorer (like steemd.com/@accountname), or on the Steemit Wallet site (steemitwallet.com/@accountname). \n\n## Alternative method without docker\n\nIf you don't have or want to use docker, you can also run this repo on any system that has Node 8.7+ and NPM installed.\n\nTo setup, run: `npm install`\n\nCommands to run:\n\n`node get_block_prefix.js`\n\n`node sign_offline_transfer.js `","has_starred","hub_user","immutable_tags_settings",{"_71":11,"_72":73},"enabled","rules",[74],".*","is_automated","permissions",{"_78":17,"_79":11,"_80":11},"read","write","admin","user","storage_size",301978722,"orgData",{"_86":87,"_88":89,"_90":91,"_92":29,"_93":94,"_95":96,"_97":94,"_98":99,"_100":101,"_102":103,"_104":96,"_105":96,"_106":17},"id","8766faf33a4c49dab9bbe232bc553d61","uuid","8766faf3-3a4c-49da-b9bb-e232bc553d61","type","organization","orgname","full_name","Steemit, Inc.","location","","company","profile_url","https://steem.io","date_joined","2016-09-02T04:15:00Z","gravatar_url","https://www.gravatar.com/avatar/6f5613561f95338317f6e549915201b3?s=80&r=g&d=mm","gravatar_email","badge","is_active","recentTags",[109],{"_110":40,"_111":112,"_113":114,"_86":115,"_116":117,"_46":134,"_135":112,"_136":29,"_137":52,"_53":138,"_139":140,"_141":125,"_142":134,"_143":62,"_144":17},"content_type","creator",1072155,"full_size",286054175,84395980,"images",[118],{"_119":120,"_121":122,"_123":96,"_124":125,"_126":127,"_128":129,"_130":96,"_131":-5,"_132":114,"_59":62,"_133":-5},"architecture","amd64","digest","sha256:bae97bf97ccc3f7e9c537969191b1a2fa5f2bce473d5fdf60054376a929ebfa5","features","last_pulled","2026-09-14T15:06:07.781049642Z","last_pushed","2020-01-29T19:53:56Z","os","linux","os_features","os_version","size","variant","2020-01-29T19:53:55.099005Z","last_updater","last_updater_username","media_type","latest","repository",8390560,"tag_last_pulled","tag_last_pushed","tag_status","v2","sbxKitMetadata","isPotentialSpam","isHubSbxKitsEnabled","displaySecurityMetadata","tagAttestations","tagsHaveAttestations",[],"routes/_layout.r.$namespace.$reponame.tags",{"_34":154,"_161":162,"_150":171,"_172":11},{"_36":155,"_38":156,"_41":42,"_43":44,"_45":11,"_46":47,"_48":49,"_50":157,"_53":31,"_28":29,"_54":55,"_56":40,"_57":58,"_59":60,"_61":62,"_63":-5,"_64":58,"_65":66,"_67":11,"_68":29,"_69":158,"_75":11,"_76":160,"_81":29,"_82":83},[],[40],[52],{"_71":11,"_72":159},[74],{"_78":17,"_79":11,"_80":11},"tags",{"_163":60,"_164":-5,"_165":-5,"_166":167},"count","next","previous","results",[168],{"_110":40,"_111":112,"_113":114,"_86":115,"_116":169,"_46":134,"_135":112,"_136":29,"_137":52,"_53":138,"_139":140,"_141":125,"_142":134,"_143":62,"_144":17},[170],{"_119":120,"_121":122,"_123":96,"_124":125,"_126":127,"_128":129,"_130":96,"_131":-5,"_132":114,"_59":62,"_133":-5},[],"canDeleteTags","actionData","errors"]
