30 Bytom is software designed to operate and connect to highly scalable blockchain networks confirming to the Bytom Blockchain Protocol, which allows partipicants to define, issue and transfer digitial assets on a multi-asset shared ledger. Please refer to the [White Paper](https://github.com/Bytom/wiki/blob/master/White-Paper/%E6%AF%94%E5%8E%9F%E9%93%BE%E6%8A%80%E6%9C%AF%E7%99%BD%E7%9A%AE%E4%B9%A6-%E8%8B%B1%E6%96%87%E7%89%88.md) for more details.
32 In the current state `bytom` is able to:
35 - Manage account as well as asset
42 - [Go](https://golang.org/doc/install) version 1.8 or higher, with `$GOPATH` set to your preferred directory
46 Ensure Go with the supported version is installed properly:
50 $ go env GOROOT GOPATH
53 #### Get the source code
56 $ git clone https://github.com/Bytom/bytom $GOPATH/src/github.com/bytom
64 $ cd $GOPATH/src/github.com/bytom
73 $ cd $GOPATH/src/github.com/bytom/cmd/bytomcli
79 Currently, bytom is still in active development and a ton of work needs to be done, but we also provide the following content for these eager to do something with `bytom`.
81 ### Create and launch a single node
83 When successfully building the project, the `bytom` and `bytomcli` binary should be present in `cmd/bytomd` and `cmd/bytomcli` directory, respectively. The next step is to initialize the node:
90 After that, you'll see `.bytom` generated in current directory, then launch the single node:
93 $ ./bytomd node --wallet.enable
96 Given the `bytom` node is running, the general workflow is as follows:
100 - create/sign/submit a transaction to transfer an asset
101 - query the assets on-chain
104 #### Create an account
106 Create an account named `alice`:
109 $ ./bytomcli create-account alice
110 xprv:<alice_account_private_key>
111 responses:<create-account-responses>
112 account id:<alice_account_id>
115 Check out the new created account:
118 $ ./bytomcli list-accounts
123 Create an asset named `gold`:
126 $ ./bytomcli create-asset gold
127 xprv:<gold_asset_private_key>
128 xpub:<gold_asset_public_key>
129 responses:<create-asset-responses>
130 asset id:<gold_asset_id>
133 Check out the new created asset:
136 $ ./bytomcli list-assets
139 #### Asset issuance test
141 Since the account `alice` and the asset `gold` are ready, we need to create another account `bob`, which is also neccessary for the following Expenditure test:
144 $ ./bytomcli create-account bob
147 Firstly, Alice issue `<issue_amount>`, e.g., 10000, `gold`:
150 $ ./bytomcli sub-create-issue-tx <alice_account_id> <bob_account_id> <gold_asset_id> <gold_asset_private_key> <issue_amount>
153 When the transaction above is mined, query the balances:
156 # Alice should have 10000 gold now
157 $ ./bytomcli list-balances
160 #### Expenditure test
164 Alice pays Bob `<payment_amount>`, e.g., 1000, `gold`:
167 $ ./bytomcli sub-spend-account-tx <alice_account_id> <bob_account_id> <gold_asset_id> <alice_private_key> <payment_amount>
168 # In our case, after Alice pays Bob 1000 gold, the amount of Alice's gold should be 9000, Bob's balances should be 1000
169 $ ./bytomcli list-balances
174 Bob pays Alice `<payment_amount>`, e.g., 500, `gold`:
177 $ ./bytomcli sub-spend-account-tx <bob_account_id> <alice_account_id> <gold_asset_id> <bob_private_key> <payment_amount>
178 # In our case, after Bob pays Alice 500 gold, the amount of Alice's gold should be 9500, Bob's balances should be 500
179 $ ./bytomcli list-balances
182 ### Set up a wallet and manage the key
184 If you have started a bytom node, then you can create an account via `create-key password`, which will generate a `keystore` directory containing the keys under the project directory.
187 $ ./bytomcli create-key account_name password # Create an account named account_name using password
188 $ ./bytomcli delete-key password pubkey # Delete account pubkey
189 $ ./bytomcli reset-password oldpassword newpassword pubkey # Update password
194 Get the submodule depenency for the two-node test:
197 $ git submodule update --init --recursive
200 Create the first node `bytomd0` and second node `bytomd1`:
203 $ cd cmd/bytomd/2node-test
204 $ ./test.sh bytomd0 # Start the first node
205 $ ./test.sh bytomd1 # Start the second node
208 Then we have two nodes:
211 $ ./bycomcli net-info
212 net-info:map[listening:true listeners:[Listener(@192.168.199.43:3332)] peers:[map[node_info:map[listen_addr:192.168.199.43:3333 version:0.1.2 other:[wire_version=0.6.2 p2p_version=0.5.0] pub_key:D6B76D1B4E9D7E4D81BA5FAAE9359302446488495A29D7E70AF84CDFEA186D66 moniker:anonymous network:bytom remote_addr:127.0.0.1:51036] is_outbound:false connection_status:map[RecvMonitor:map[Start:2017-10-30T13:45:47.18+08:00 Bytes:425130 AvgRate:27010 Progress:0 Active:true Idle:1.04e+09 Samples:42 InstRate:4591 CurRate:3540 PeakRate:114908 BytesRem:0 TimeRem:0 Duration:1.574e+10] Channels:[map[RecentlySent:5332 ID:64 SendQueueCapacity:100 SendQueueSize:0 Priority:5]] SendMonitor:map[Active:true Idle:1.24e+09 Bytes:16240 Samples:41 CurRate:125 AvgRate:1032 Progress:0 Start:2017-10-30T13:45:47.18+08:00 Duration:1.574e+10 InstRate:147 PeakRate:4375 BytesRem:0 TimeRem:0]]]]]
