EOS命令行账号操作入门

EOS账号体系相对BTC和ETH是一个很创新的做法,对于很多区块链入门者来说也是比较难懂的地方。

BTC和ETH没有账号的概念,只有地址,转账都是发生在地址上,所以每次转账需要手续费,矿工才愿意打包这个转账交易。

EOS的账号概念优点是转账免手续费,但是需要抵押资源,就是把EOS换成资源抵押在这个账号上(后续随时可以解除抵押,没有任何费用),只要抵押的资源足够,这个账号的任何操作,包括转账等,都能正常使用。

缺点就是,当链上交易很多的时候,要抵押很多EOS才能换取足够的资源。也就是网络拥堵问题。这是区块链的最大问题之一。

抵押资源

为他人抵押资源

抵押资源,抵押资源的特点在于可以回收。类似一种租借,随时可以讨回来。 比如 githubdancer 这个账号没有资源导致无法转账的话。可以用自己的账号,比如practicetest 抵押资源给 githubdancer ,

cleos -u http://peer1.eoshuobipool.com:8181 system delegatebw practicetest githubdancer '0 EOS' '1 EOS'

为自己抵押资源

创建账号

这个过程是比较复杂的过程了。

每次创建账号必须填写,创建账号的父账号(因为创建账号所需的资源是父账号来出。), 创建账号需要购买内存和抵押资源(资源包括CPU和网络),这里面可以理解为,购买内存就是真正创建账号所需要消耗的。 因为购买后,以后如果内存要卖回去,也无法全量卖出去,毕竟账号本身就占用了内存。而且卖出去的价格也不确定是当时买的价格,或涨或跌,但是长期来看,内存价格应该是下降的趋势。

抵押资源就不一样了,可以随时换回EOS。这里有些不理解的地方就是那换回EOS的操作也是需要资源的,那怎么办。可以用其他账号给这个账号抵押,去进行操作就行。

所以【购买】内存和【抵押】资源,这里的【购买】和【抵押】用词就是很耐人寻味了。

创建成功后可以用账号名查询到账号信息了。

cleos -u http://peer1.eoshuobipool.com:8181 get account abtestabtest

变更账号的权限

cleos -u http://peer1.eoshuobipool.com:8181 set account permission abtestabtest active '{"threshold": 1, "keys": [{"key": "EOS6Xe5G1KZVVqYm1gGwPWHUybYph3eK9nW7Kh23Z1WXjvgJEbc2k", "weight": 1}, {"key": "EOS7NQgj1E6xAHNvgjqjCvQ5eksPd2paHFyyUub9wwuyFhGZDrSgy", "weight": 1}]}' owner

executed transaction: 6fc9eb30ea547006d74e342ab5effc66bebb9539405111227a02547b4b2fd4de  200 bytes  169 us

这里需要注意的是,每次变更都是一次重写,所以如果要删除权限,也是重写权限的时候不带上你不想要的权限的公钥就行。

cleos -u http://peer1.eoshuobipool.com:8181 set account permission abtestabtest active '{"threshold": 1, "keys":  [{"key": "EOS7NQgj1E6xAHNvgjqjCvQ5eksPd2paHFyyUub9wwuyFhGZDrSgy", "weight": 1}]}' owner
