When you transfered the token to another account, you can see the console log in terminal...
Like this :
eos@ubuntu:~$ cleos transfer eosio account_name "0.1 SYS"
executed transaction: 681e8f2153103351f3ef028d3c13963546091ec07803b8d3d97c07da58549e27 128 bytes 2180 us
# eosio.token <= eosio.token::transfer {"from":"eosio","to":"innocent.eom","quantity":"0.1000 SYS","memo":""}
# eosio <= eosio.token::transfer {"from":"eosio","to":"innocent.eom","quantity":"0.1000 SYS","memo":""}
# innocent.eom <= eosio.token::transfer {"from":"eosio","to":"innocent.eom","quantity":"0.1000 SYS","memo":""}
Thus i got a question. What transaction was made is only one but transfering actions are three times way. Why this happen??
