Ipfs node address?

你好，我在你们的白皮书里看到：

个人信息数据是加密存储在 ipfs 上面的

我想要自己去访问一下这些加密的文件，但我遇到两个问题：

首先是你们存储这些文件的 ipfs 地址是哪个呢？另外可否告知一下目录结构？
你们提到使用非对称加密，那这里的 private key 具体是指哪个呢？

构建节点出现的非预期提示。

执行如下命令

./programs/witness_node/witness_node --data-dir=trusted_node --rpc-endpoint=127.0.0.1:28090 --p2p-endpoint=0.0.0.0:6789 --log-file  --partial-operations=true

以上问题，是否属于正常。若不正常，应当如何处理？如删除缓存文件等解决方式。

Wallet API : get_account_history / get_account_histroy_by_operations return empty

Are there any problems in cli_wallet for calling get_account_history / get_account_histroy_by_operations if I connect it to my local witness_node ws://127.0.0.1:28090? It always return empty.

Params : {"jsonrpc": "2.0", "method": "get_account_history_by_operations", "params": ["1.2.17", [0,1], 1, 5], "id": 2}
Return : {"id":2,"jsonrpc":"2.0","result":{"total_without_operations":5,"details":[]}

I already used any APIs like transfer2, list_account_balances, get_block, etc, and it run well and give the feedbacks.

But the API will return the histories if I connect my cli_wallet to wss://node1.gxb.io.

My cli_wallet Version: v1.0.180929.

你好，执行第二步 Install dependencies 时报了这个错误，网上找不到解决方式；请问下有解决办法吗？

gxx编译优化

去除合约中未包含的引用，减少编译文件大小，降低开发者部署智能合约的费用

erro While importing wallet

I am doing
import_key some_name some_key
but the wallet_cli return
rec && rec->name == account_name_or_id:
{}
th_a wallet.cpp:602 get_account

Am i missing anything here ? I tried putting quotes to the string too, no luck
My syncing hasnt finished tho, do I need to wait the node finish syncing first ? As the wallet I created from the online wallet just recently (from wallet.gxb.io)

增加智能合约收费方案testcase

同一块内存占用，从fee_payer A变更为fee_payer B
跨合约调用的手续费支付方权限控制，不相关调用方不能作为手续费支付对象

其他：待补充

尝试弄懂 operation 的含义，发现了安全问题？

你好，今天偶然看到你们的项目，去看了一下你们的 blockchain explorer .
我注意到你们在 graphene 的基础上添加很多 operations.

可否在之后给出这些 operations 的具体文档呢？
我有注意到，你们新添加的一些比较重要的 operations 中的 validate 是没有实现的，这意味着这个 tx 完全没有验证？？！！还是我的理解有问题呢？

Hi, I'm wondering whether the test net of gxchain has been stopped?

After using specific command to connect to the test of gxchain, after downloading all the blocks in test net, when I use "info" command, I got "head_block_num": 3479962, and "head_block_age": "18 days old".
And still it won't increase, who can give me some suggestion on how to resolve this problem, thanks a lot!

query the transaction with txid

qurey the rawtransaction with TXID

witness_node add command line option:

 -txindex
       Maintain a full transaction index, used by the getrawtransaction rpc call (default: false)

DB API:
request:

curl --data '{"jsonrpc": "2.0", "method": "call", "params": [0, "getrawtransaction", ["9e237106f2ccb7681692a25e1e57a45e5708e58b"]], "id": 1}' http://127.0.0.1:28090

How to register an account on private chain?

I have successfully installed private network. Now, I want to transfer coin, but I dont know account_id or account_name.
So, how do I register a account via JSON-RPC on private network?

can't install libstdc++-8-dev

I tried to install libstdc++-8-dev dependency via apt-get on Ubuntu 14.04.5 LTS,but I got an error as follows.Do you have any idea about this issue? thanks!

关于节点丢块

目前公信链应该是每小时 40分的时候进行投票统计，该操作会造成刚好该时间点出块的节点丢块~

get_table_rows_ex 接口建议收集

get_table_rows_ex接口是get_table_rows的扩展接口。(对于该接口还有哪些改进建议，需要修改或者添加的，可以详细回复讨论)

目前正在初步实现如下扩展：
1、可以通过多种索引方式返回数据。
2、倒序输出lower_bound ~ upper_bound 范围的项。
3、参数修改为结构体，某些字段不提供则使用默认值。

参数字段：
contract 合约名
table 表名
params get_table_rows_params类型结构体

// get_table_rows_params类型结构体
// 字段不传，则使用默认值
struct get_table_rows_params {
   uint64_t      lower_bound = 0;       // 最小边界 （0~-1则返回表中所有的项）
   uint64_t      upper_bound = -1;      // 0xFFFFFFFFFFFFFFFF 最大边界
   uint32_t      limit = 10;            // 获取的项的数目
   std::string   index_position = "1";  // 1 - primary (first), 2 - secondary index (in order defined by multi_index), 3 - third index, etc 主键索引方式
   optional<bool>  reverse = false;     // 是否反向输出
};

调用示例：muli1202 是合约名，mytable是表名，该表共有三种索引方式（id、field1、field2）
cli_wallet:

// 使用默认字段 （范围：0~-1、limit=10、主键索引、不反向）
get_table_rows_ex muli1202 mytable {}
{
  "rows": [{
      "id": 0,
      "field1": 3,
      "field2": 2
    },{
      "id": 1,
      "field1": 4,
      "field2": 7
    },{
      "id": 2,
      "field1": 2,
      "field2": 5
    },{
      "id": 3,
      "field1": 7,
      "field2": 1
    },{
      "id": 4,
      "field1": 3,
      "field2": 3
    }
  ],
  "more": false
}
// 设置自定义范围（范围 0~2、limit=10、主键索引、不反向）
get_table_rows_ex muli1202 mytable {"lower_bound":0,"upper_bound":2}
{
  "rows": [{
      "id": 0,
      "field1": 3,
      "field2": 2
    },{
      "id": 1,
      "field1": 4,
      "field2": 7
    }
  ],
  "more": false
}
// 设置自定义数据条目（范围：0~-1、主键索引、不反向）
get_table_rows_ex muli1202 mytable {"limit":3}
{
  "rows": [{
      "id": 0,
      "field1": 3,
      "field2": 2
    },{
      "id": 1,
      "field1": 4,
      "field2": 7
    },{
      "id": 2,
      "field1": 2,
      "field2": 5
    }
  ],
  "more": false
}
// 使用二级索引（2表示二级索引，此例中使用field1 为索引方式，不反向）
get_table_rows_ex muli1202 mytable {"index_position":2}
{
  "rows": [{
      "id": 2,
      "field1": 2,
      "field2": 5
    },{
      "id": 0,
      "field1": 3,
      "field2": 2
    },{
      "id": 4,
      "field1": 3,
      "field2": 3
    },{
      "id": 1,
      "field1": 4,
      "field2": 7
    },{
      "id": 3,
      "field1": 7,
      "field2": 1
    }
  ],
  "more": false
}
// 将指定范围的数据反向输出（范围：0~-1、主键索引、反向）
get_table_rows_ex muli1202 mytable {"reverse":1}
{
  "rows": [{
      "id": 4,
      "field1": 3,
      "field2": 3
    },{
      "id": 3,
      "field1": 7,
      "field2": 1
    },{
      "id": 2,
      "field1": 2,
      "field2": 5
    },{
      "id": 1,
      "field1": 4,
      "field2": 7
    },{
      "id": 0,
      "field1": 3,
      "field2": 2
    }
  ],
  "more": false
}

获取末尾2条数据，倒序获取

get_table_rows_ex muli1202 mytable {"limit":2,"reverse":1}
{
  "rows": [{
      "id": 6,
      "field1": 1,
      "field2": 9
    },{
      "id": 5,
      "field1": 8,
      "field2": 0
    }
  ],
  "more": false
}

使用curl调用示例：

curl --data '{
    "jsonrpc": "2.0",
    "method": "call",
    "params": [0, "get_table_rows_ex", ["muli1202", "mytable", {"lower_bound":0,"upper_bound":-1,"limit":10,"index_position":1,"reverse":0}]],
    "id": 1
}' 127.0.0.1:28089

private gxchain

Hi, I tried to create a private gxchain following the instructions in tech-doc. After successfully setup a witness node, I then tried to add another witness node into the private network.

but when I try to startup 2nd witness node, it prompted error message

If I enable stale production to true, it will create new chain, which is not expected. it doesn't sync to my 1st chain.

安卓app没有账户的数字id

初学者入门，按照教程使用witness_node时，使用安卓app找了半天没有发现有数字账号。这个和文档里面的说明不符，后来从网页上重新注册了一个钱包才有数字账户
希望能够对app改进

add stealth contract api

add the following api to support contract stealth transaction:

verify_commitment
verify_range
verify_balance

support network_broadcast api for http

Synchronization is too slow and only few nodes keep connection.

Describe the bug
A clear and concise description of what the bug is.
the title is the problem what I have.
Should I set another configurations like seed-node?

Another question. Which one is most correct technical document?

To Reproduce
Steps to reproduce the behavior:

run witness_node and start synchronize(first run)

$ ./bin/witness_node --data-dir=./witness_node_data_dir --rpc-endpoint=127.0.0.1:28090 --p2p-endpoint=0.0.0.0:6789 --log-file --track-account ""1.2.1004580"" --partial-operations=true --max-ops-per-account=100 --plugins account_history

I checked the correct log in witness.log

also I check connection status by using lsof

I checked P2P.log

It keeps print out following error message
