Test eosio.wrap on Kylin Testnet
准备测试账户
Kylin 测试网络新建了两个账户用于 wrap 合约测试，分别为 updatemyauth 和 transmytoken，两个账户的 active 和 owner key 均为 EOS1111111111111111111111111111111114T1Anm，如下所示：

CASE 1. wrap 变更 updatemyauth 账户的 active key
第一步，生成变更 active key 的 transaction 数据
我们将 updatemyauth 账户的 active key 改为 EOS6GR1JqeNmp5d7FGRt3Rx1BGQ1QxUk65nkfcnuprAs1BVNNWqSD
首先，我们生成 updateauth 数据：
cleos set account permission -s -j -d updatemyauth active EOS6GR1JqeNmp5d7FGRt3Rx1BGQ1QxUk65nkfcnuprAs1BVNNWqSD owner > updatemyauth.json
cat updatemyauth.json
{
"expiration": "2018-08-09T09:40:33",
"ref_block_num": 8064,
"ref_block_prefix": 90673647,
"max_net_usage_words": 0,
"max_cpu_usage_ms": 0,
"delay_sec": 0,
"context_free_actions": [],
"actions": [{
"account": "eosio",
"name": "updateauth",
"authorization": [{
"actor": "updatemyauth",
"permission": "active"
}
],
"data": "d0b2365eaa6c52d500000000a8ed32320000000080ab26a701000000010002b57ac63750eca19d2e7a36ba46057e4d8a6a981849f883b5c731c33b86fdc82a01000000"
}
],
"transaction_extensions": [],
"signatures": [],
"context_free_data": []
}
将上述文件中的 ref_block_num 和 ref_block_prefix 改为 0，将 expiration 改为 1970-01-01T00:00:00
第二步，调用 wrap 合约执行上述命令，生成最终的 transaction data
生成 sudo_update_updatemyauth_active_trx.json 文件：
cleos wrap exec -s -j -d BP_ACCOUNT updatemyauth.json > sudo_update_updatemyauth_active_trx.json
cat sudo_update_updatemyauth_active_trx.json
{
"expiration": "2018-08-09T09:43:33",
"ref_block_num": 8424,
"ref_block_prefix": 3790583261,
"max_net_usage_words": 0,
"max_cpu_usage_ms": 0,
"delay_sec": 0,
"context_free_actions": [],
"actions": [{
"account": "eosio.wrap",
"name": "exec",
"authorization": [{
"actor": "eoslaomaocom",
"permission": "active"
},{
"actor": "eosio.sudo",
"permission": "active"
}
],
"data": "2029a246521331550000000000000000000000000000010000000000ea30550040cbdaa86c52d501d0b2365eaa6c52d500000000a8ed323243d0b2365eaa6c52d500000000a8ed32320000000080ab26a701000000010002b57ac63750eca19d2e7a36ba46057e4d8a6a981849f883b5c731c33b86fdc82a0100000000"
}
],
"transaction_extensions": [],
"signatures": [],
"context_free_data": []
}将上述文件中的 ref_block_num 和 ref_block_prefix 设置为 0，将 expiration 的日期向后推迟一定的时间（比如 1 天后），这个时间表示 transaction 的过期时间。由于这个 transaction 最终需要等待 BP 多签生效，因此过期时间不能太短。
第三步，生成 producer_permissions.json 文件
假设网络中有 21 个 BP，名字分别为，blkproducera，blkproducerb，......，blkproduceru。则 producer_permissions.json 的文件内容如下所示：
$ cat producer_permissions.json
[
{"actor": "blkproducera", "permission": "active"},
{"actor": "blkproducerb", "permission": "active"},
{"actor": "blkproducerc", "permission": "active"},
{"actor": "blkproducerd", "permission": "active"},
{"actor": "blkproducere", "permission": "active"},
{"actor": "blkproducerf", "permission": "active"},
{"actor": "blkproducerg", "permission": "active"},
{"actor": "blkproducerh", "permission": "active"},
{"actor": "blkproduceri", "permission": "active"},
{"actor": "blkproducerj", "permission": "active"},
{"actor": "blkproducerk", "permission": "active"},
{"actor": "blkproducerl", "permission": "active"},
{"actor": "blkproducerm", "permission": "active"},
{"actor": "blkproducern", "permission": "active"},
{"actor": "blkproducero", "permission": "active"},
{"actor": "blkproducerp", "permission": "active"},
{"actor": "blkproducerq", "permission": "active"},
{"actor": "blkproducerr", "permission": "active"},
{"actor": "blkproducers", "permission": "active"},
{"actor": "blkproducert", "permission": "active"},
{"actor": "blkproduceru", "permission": "active"}
]第四步，发起多签 proposal，approve 并执行
发起 proposal：
$ cleos multisig propose_trx updateactive producer_permissions.json sudo_update_updatemyauth_active_trx.json PROPOSER_ACCOUNTBP 分别 approve
cleos multisig approve PROPOSER_ACCOUNT updateactive '{"actor": "BP_ACCOUNT", "permission": "active"}' -p BP_ACCOUNTapproval 达到 15/21 之后，执行该 proposal：
cleos multisig exec PROPOSER_ACCOUNT updateactive ANY_ACCOUNT*注意，任何账户都可以执行 approval 达到 15/21 的 proposal，即使该账户不是 BP。
Kylin 测试网络中已经提交 updateactive proposal：https://tools.cryptokylin.io/#/msig?proposer=eoslaomaocom&proposal=updateactive
CASE 2. wrap 变更 updatemyauth 账户的 owner key
我们将 updatemyauth 账户的 owner key 改为 EOS6GR1JqeNmp5d7FGRt3Rx1BGQ1QxUk65nkfcnuprAs1BVNNWqSD
CASE 2 和 CASE 1 类似，唯一的不同在于第一步骤的时候，生成 updatemyauth.json 的命令稍有不同。
更改 owner key 的命令不需要指定 parent permission：
cleos set account permission -s -j -d updatemyauth owner EOS6GR1JqeNmp5d7FGRt3Rx1BGQ1QxUk65nkfcnuprAs1BVNNWqSD > updatemyauth.json其余步骤请参考 CASE1。
Kylin 测试网络中已经提交 updateowner proposal：https://tools.cryptokylin.io/#/msig?proposer=eoslaomaocom&proposal=updateowner
CASE 3. wrap 转移 transmytoken 账户中的 EOS
第一步，生成 transfer data
我们将 transmytoken 账户的 1 EOS 转移给 eosio 账户，命令如下：
cleos transfer -s -j -d transmytoken eosio "1 EOS" "steal 1 EOS from you!" > transmytoken.json
cat transmytoken.json
{
"expiration": "2018-08-09T09:52:27",
"ref_block_num": 25799,
"ref_block_prefix": 1477572235,
"max_net_usage_words": 0,
"max_cpu_usage_ms": 0,
"delay_sec": 0,
"context_free_actions": [],
"actions": [{
"account": "eosio.token",
"name": "transfer",
"authorization": [{
"actor": "transmytoken",
"permission": "active"
}
],
"data": "3015a4d94b3ccdcd0000000000ea3055102700000000000004454f530000000015737465616c203120454f532066726f6d20796f7521"
}
],
"transaction_extensions": [],
"signatures": [],
"context_free_data": []
}将上述文件中的 ref_block_num 和 ref_block_prefix 改为 0，将 expiration 改为 1970-01-01T00:00:00
其余步骤请参考 CASE1。
Kylin 测试网络中已经提交 transtoken proposal：https://tools.cryptokylin.io/#/msig?proposer=eoslaomaocom&proposal=transtoken
