- [ ] 在 testnet 部署 always success 合约，并使用 type id 作为 type script
- [ ] 创建一个 lock 和 type 都使用 type script hash 引用 always success 的 cell
- [ ] 升级一次 always success，可以不修改 data
- [ ] 使用升级后的 always success 组装交易解锁第三步中的 cell

### ckb两步提交

- [x] 自己在 Explorer 找一个块手算 Cellbase 奖励和手续费

block: [6478265](https://pudge.explorer.nervos.org/block/6478265)
奖励对象：6478265 - 11 = [miner](https://pudge.explorer.nervos.org/address/ckt1qzda0cr08m85hc8jlnfp3zer7xulejywt49kt2rr0vthywaa50xwsq03ewkvsva4cchhntydu648l7lyvn9w2cctnpask) of [6478254 block](https://pudge.explorer.nervos.org/block/6478254) 

Epoch: 4,947
Block Index: 372/1800

一级增发：
Eopch 总额: 1,917,808.21917808

1,917,808.21917808 / 1800 = 1065.44901065

二级增发：

613698.63013698 / 1800 = 340.94368340943333

340.94368340943333 * (594424732800000000 / 4612388749964379586) = 43.939348761976184


Commit 手续费：

(0.00100000 + 0.00001000 + 0.00001000 + 0.00001000 + 0.00039422 + 0.00003140 + 0. 00002140) * 0.6 = 0.000886212

Proposal 手续费：

CKB> rpc get_block --hash 0xe14fca3122ae8a6874f1f07d66891196386dbaa2f7f863894518d5456d7df5f1 proposals:

手续费

总手续费 = 1,065.44901066 + 43.93934975 + 0.00088622 + 0.00032152 = 1,109.38956815

Q: Why there is no output of cellbase in blocks 1 to 11 on ckb?

A: 因为cellbase规定区块n的 Cellbase Output 是发放给 N - 11 的区块生产者，在1-11这些区块中没有n - 11的区块生产者，所以不会有cellbase output

ckb难度提交

Q: What is the difference between the meaning of uncle in Ethereum and uncle in CKB?

ckb中挖出叔块没有奖励，但是打包叔块的矿工可以获得奖励。

以太坊中挖出叔块有奖励
