EOS学习阶段性总结

   dawn3.0编译过程参考 https://github.com/eosio/eos readme.md 
 

   # 创建默认钱包 
 

   ./cleos wallet create 
 

   # 设置基础配置智能合约：eosio.bios 
 

   ./cleos set contract eosio ../../contracts/eosio.bios -p eosio -j 
 

   # 设置系统智能合约：eosio.system 部署了该智能合约，eosio账户才可以给包括自己在内的所有账户发行EOS token，执行注册producer、投票者下注、投票等操作 
 

   ./cleos set contract eosio ../../contracts/eosio.system -j 
 

   # 给eosio账户发行EOS token 10个亿

   # 查看钱包中的密钥对 
 

   ./cleos wallet keys 
 

   # 创建账户 currency 
 

   ./cleos create account eosio currency EOS6a5pr4DS4CksCQSHqTdKMPbAdCyrE4b7QExDwTuCxH1vbkYMqG EOS5NiFNF4bG7T49S6f7qVXMAt4RN2WM211s77UZrwD4cz2Xu6gw9 -j 
 

   # 设置currency的智能合约

   # currency token 转账 
 

   ./cleos push action currency transfer '{"from":"currency","to":"eosio","quantity":"200.0000 CUR","memo":"my first transfer"}' --permission currency@active -j 
 

   # 查询余额 CUR 
 

   ./cleos get currency balance currency eosio 
 

   ./cleos get currency balance currency currency 
 

   # EOS token 转账有问题，转账可以成功，余额查询为空，原来这是EOS的一个BUG， 
 

   #eosio 给currency 转账 EOS币后，currency余额查不到，eosio有两个余额 
 

   #然后currency 再给eosio转帐0个EOS，再查余额，一切正常。 
 

   ./cleos transfer eosio currency 100000000 -j 
 

   # 查询余额 EOS，eosio账户会有两个余额，currency账户是空的 
 

   ./cleos get currency balance eos eosio 
 

   ./cleos get currency balance eos currency 
 

   # 执行这个回转0，后面查询就正确了 
 

   ./cleos transfer currency eosio 0 -j 
 

   # 查询余额 EOS 一切正常 
 

   ./cleos get currency balance eos eosio 
 

   ./cleos get currency balance eos currency 
 

   如果还是不正常，可能需要修改chain_plugin.cpp文件 321行开始， 
  get_currency_balance修改成下面这样

           //   ("payer",ite->payer)("cursor",cursor)("id",ite->id._id)("t_id",ite->t_id._id));
         }

   结论性总结：bp = block producer =区块生产者 
 

   1、首先需要创建个钱包，才可以做其它操作 
 

   2、如果要进行EOS token 发行,转账,超级节点注册，投票人押注，投票等操作，部署eosio.bios和eosio.system这两个系统合约是必要前提 
 

   3、需要生成密钥，并导入到钱包，才可创建账户 
 

   4、bp工作前要先创建账户，再注册成为bp 
 

   5、投票人投票前需要先押注 
 

   6、使用相关命令使21个bp正常工作 
 

   7、在pb满21个工作的时候，投票人撤销下注，对应的bp停止工作；在只有一个bp工作的情况下，投票人撤销下注，bp的工作不会停止 
 

   8、21个producer 工作过程中，按照对应投票人押注的多少，确定打块顺序，一人打12个块，打完就走，等待下轮 
 

   9、投票人可以随时增加押注，也可以减少押注，减少的部分代币不会立即回到账户 
 

   10、随着投票人押注多少的变化打块顺序会有相应调整 
 

   11、如果备选的producers中有某一个支持者（投票人）的押注数量超过目前当选的21个bp中的至少一个bp,被超过的那个当前bp会被超过他的备选bp替换 
 

   12、总之投票可以是一直在进行的，当前正在工作的21个bp,随时有可能被替换 
 

   13、有人说EOS 只有21个超级节点产生区块数据，并非真正的去中心化，其实我觉得：投票不止，替换不息。
