我正在研究EOS RAM分配，CPU和网络带宽，我想知道组织一次真正的空投需要花费多少钱。所以我刚刚在Jungle测试网络的小实验，它可以完全适应于Mainnet，因为存储和bandwith是相同的，您可以调整当前的EOS和RAM价格。

在EOS <3中它实际上超级简单

1、为您的智能合约创建一个帐户

2、从eos存储库下载官方eosio.token（https://github.com/EOSIO/eos/tree/013c282edb3513078c573d4feb626403778af954/contracts/eosio.token）

3、编译并将其部署到您的合同

4、创建您的代币符号和供应

5、开始发放代币

以下我将详细展开以上的各步骤，让我们开始吧！

在Junglenet上创建默认帐户

从 http://dev.cryptolions.io/#account 创建eosairdroper账户

以下是初始帐户余额和利率统计信息：

$ cleos get account eosairdroper

部署`eosio.token`合同

从原始EOS Repo简单部署，无需任何更改：

是的，部署的成本 eosio.token 是今天版本的186.335 Kb！好的，好玩的就要开始了......让我们创建一个token！

创建一个token

默认token，如同EOS一样，10亿个的供应及精确到小数点后四位。

接下来！为了创建一个token，我们花费的资源很少，甚至几乎没有...

发行一些toekn

现在让我们空投一些token！

我正在使用官方快照中的一些随机帐户（如果其中有你的，不好意思了）：

经过6小时后

看起来像我网络的CPU bandwith了一点，完美！

B1大空投

测试一大笔空投到B1（并不是真的需要这笔空投，通常这将取决于空投团队）

$ cleos push action eosairdroper issue '["b1", "100000000.0100 TOKEN", "airdrop"]' -p eosairdroper executed transaction: 8458b5f23d6764333db5ba2d8133cabe65265abf6ecf674810a8eb1de05e25f7 128 bytes 2540 us

没有MEMO

测试到没有memo空投给另一个随机帐户ge3dmgenesis: 1000.5425 EOS- bandwith的使用情况从128字节减少到的120字节，在cpu上没有任何重大变化，并且不影响RAM上的任何内容，全被记住了，从eosio.token合同中我们不会将memo存储在任何地方。

cleos push action eosairdroper issue '["ge3dmgenesis", "1000.5425 TOKEN", ""]' -p eosairdroper executed transaction: 34d05c59c10049ae946ad4e66703bb42987d1a1ce248115f3bea4bb6b1120e7f 120 bytes 2387 us

结果

如果我们假设上述数值为近似平均值（我需要加载一批数千个帐户来确保），这些数据是基于官方mainnet（https://github.com/eoscafe/eos-snapshot-validation ）启动快照完整空投所需的统计数据：

WechatIMG130.jpeg

您最终会想要从空投中删除一些账户，如B1，交易所等。

这些还是来自创世快照的其他的有趣数据：

WechatIMG131.jpeg

Mainnet

截至今天，几个小时前，我们创建了一个账户，其RAM内存价格为0.015 EOS / Kb。

所以，如果你现在正在计划一个空投，那么官方的创世纪快照将耗资约563 EOS，现在转换为6025.17美元。我不考虑网络和CPU，因为它在3天内完全恢复，那么你可以分开你的空投。

我的下一步是运行一大批发行交易的代币，这样我就可以证明所有这些统计资料都是正确的。

也非常感谢@nsjames，@syedjafri和@blockliberty 很好的见解，关于讨论和价格！当然，还有这个很好用的Jungle Testnet @cryptolions
