# BOS Oracle Deployment

## 1. Create Oracle Contract Account `oracle.bos`

### 1.1. Export the basic info the account

oracle.bos.json

```
["eosio", "oracle.bos", {
      "threshold": 1,
      "keys": [],
      "accounts": [{
      "permission": {
      "actor": "eosio",
      "permission": "active"
     },
    "weight": 1
    }
  ],
  "waits": []
}, {
       "threshold": 1,
       "keys": [],
       "accounts": [{
       "permission": {
       "actor": "eosio",
       "permission": "active"
      },
     "weight": 1
   },{
     "permission": {
     "actor": "oracle.bos",
     "permission": "eosio.code"
    },
    "weight": 1
  }
 ],
 "waits": []
}]
```

### 1.2. Create `newaccount` ACTION

```
cleos push action eosio newaccount ./oracle.bos.json -sdj -p eosio > oracle.trx
```

### 1.3. Generate `buyram` ACTION

```
cleos system buyram -k eosio oracle.bos 3000 -sdj > oracle-ram.trx
```

### 1.4. Create `delegatebw` ACTION

```
cleos system delegatebw eosio oracle.bos "2 BOS" "2 BOS" -sdj > oracle-delegate.trx
```

### 1.5. Combine ACTIONs into `neworacle.json`，create proposal

```
cleos multisig propose_trx createtest bppermission.json  neworacle.json  bostesterter
```

neworacle.json：

```
{
  "expiration": "2019-04-27T01:43:42",
  "ref_block_num": 33447,
  "ref_block_prefix": 2283537730,
  "max_net_usage_words": 0,
  "max_cpu_usage_ms": 0,
  "delay_sec": 0,
  "context_free_actions": [],
  "actions": [{
      "account": "eosio",
      "name": "newaccount",
      "authorization": [{
          "actor": "eosio",
          "permission": "active"
        }
      ],
      "data": "0000000000ea3055000000bdf79eb1ca0100000000010000000000ea305500000000a8ed32320100000100000000010000000000ea305500000000a8ed3232010000"
    },{
      "account": "eosio",
      "name": "buyrambytes",
      "authorization": [{
          "actor": "eosio",
          "permission": "active"
        }
      ],
      "data": "0000000000ea3055000000bdf79eb1ca00240000"
    },{
      "account": "eosio",
      "name": "delegatebw",
      "authorization": [{
          "actor": "eosio",
          "permission": "active"
        }
      ],
      "data": "0000000000ea3055000000bdf79eb1ca102700000000000004424f5300000000102700000000000004424f530000000000"
    }
  ],
  "transaction_extensions": [],
  "signatures": [],
  "context_free_data": []
}
```

## 2. Set contract

### 2.1 Create `set contract` ACTION

```
cleos set contract oracle.bos bos.oracle/ -p oracle.bos  -s -j -d > setcontract.json
```

### 2.2 Create MSIG

```
cleos multisig propose_trx setcontract bppermission.json  setcontract.json  -p bostesterter
```

### 2.3 BPs `approve` MSIG

```
cleos multisig approve bostesterter updatasystem '{"actor":"${BP_NAME}","permission":"active"}' -p ${BP_NAME}
```

### 2.4 `exec` execute MSIG

```
cleos multisig exec bostesterter setcontract -p bostesterter@active
```

### 2.5 Initialize Oracle

```
cleos push action ${contract_oracle} setparameter '{"version":1,"parameters":{"core_symbol":"BOS","precision":4,"min_service_stake_limit":1000,"min_appeal_stake_limit":200,"min_reg_arbitrator_stake_limit":10000,"arbitration_correct_rate":60,"round_limit":3,"arbi_timeout_value":86400,"arbi_freeze_stake_duration":259200,"time_deadline":86400,"clear_data_time_length":10800,"max_data_size":256,"min_provider_limit":1,"max_provider_limit":100,"min_update_cycle":1,"max_update_cycle":8640000,"min_duration":1,"max_duration":8640000,"min_acceptance":1,"max_acceptance":100}}' -p ${contract_oracle} -s -j -d  > setconfig.json

cleos multisig propose_trx setconfig bppermission.json setconfig.json  -p ${account}   

cleos multisig approve ${account} setconfig '{"actor":"${account}","permission":"active"}' -p ${account}

cleos multisig exec ${account} setconfig -p ${account}
```

\_Note: the meanings of parameters: [Configurations](https://github.com/boscore/Documentation/blob/master/Oracle/BOS_Oracle_Introduction.md#27-configurations)

## 3. Import Arbitrators

### 3.1 Create `importwps` ACTION

```
cleos push action oracle.bos importwps '[["arbitrator11","arbitrator12","arbitrator13","arbitrator14","arbitrator15","arbitrator21","arbitrator22","arbitrator23","arbitrator24","arbitrator25", "arbitrator31", "arbitrator32","arbitrator33", "arbitrator34", "arbitrator35",  "arbitrator41",  "arbitrator42", "arbitrator43", "arbitrator44", "arbitrator45"]]' -p oracle.bos -s -j -d > importwps.json
```

### 3.2 Create MSIG

```
cleos multisig propose_trx insertwps  bppermission.json  importwps.json  -p bostesterter 
```

### 3.3 BPs `approve` MSIG

```
cleos multisig approve  bostesterter insertwps '{"actor":"bostesterter","permission":"active"}'  -p  bostesterter
```

### 3.4 `exec` MSIG

```
cleos multisig exec bostesterter insertwps -p bostesterter@active
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://boscore.gitbook.io/docs/essentials/bos-ecosystem/bos-oracle/bos-oracle-deployment.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
