EOS Transaction

EOS Transaction

转账 Transfer (转移凭证)

转账时候的金额精度需要和发行该token时保持一致，

[root@test-work2 ~]# cleos push action eosio.token transfer '[ "kevin", "coco", "25.0000 CL", "fa goong zi le ." ]' -p kevin@active
executed transaction: e4ec2bf220038850e2b3f78af7d96ecb6f56d78ab61833e2351716eefb8cb91e  144 bytes  386 us
#   eosio.token <= eosio.token::transfer        {"from":"kevin","to":"coco","quantity":"25.0000 CL","memo":"fa goong zi le ."}
#         kevin <= eosio.token::transfer        {"from":"kevin","to":"coco","quantity":"25.0000 CL","memo":"fa goong zi le ."}

[root@test-work2 ~]# 

查询余额

[root@test-work2 ~]# cleos get currency balance eosio.token coco CL
25.0000 CL
[root@test-work2 ~]# cleos get currency balance eosio.token kevin CL
75.0000 CL
[root@test-work2 ~]# 

EOS交易验证

• 交易excuted --> 验证transaction status参数为"executed"
• 不可逆，即交易所在区块号低于当前最新不可逆块号
  –>获得transaction所在区块的区块号以及主网最新不可逆块的区块号（不可逆区块高度），判断block_num<last_irreversible_block_num;
• 合约账户和货币符号，假币攻击就是因为交易所没验证合约账户
• From和to，即转入转出的账户需要再次确认

打包交易签名

sign_transaction
打包签名，需要启动钱包api(keosd服务)
