1)校验算法：https://github.com/leifjacky/ckb-gominer-demo/tree/master/eaglesong/src
2) 用这个demo里面的headerhash+nonce1+nonce2 测试过校验算法没问题：https://github.com/leifjacky/ckb-gominer-demo

本地计算powhash<block.target, 但是submit 之后节点校验不通过，请帮忙确认会是什么可能

用的哪个版本？ v0.32.0-rc1 在使用 testnet spec 的清空下用了新的算法，和现在的算法是不兼容的。最新的 develop 分支上也是一样。

Header

To ease PoW computation, the header is split into raw and nonce.

struct Header {
    raw:                    RawHeader,
    nonce:                  Uint128,
}

The header must meet the last inequality in the following snippet:

pow_hash := ckbhash(molecule_serialize(raw))
pow_message := pow_hash || to_le(nounce)
pow_output := eaglesong(pow_message)

from_be(pow_output) <= compact_to_target(raw.compact_target)

Functions used in the pseudocode:

:=: assignment
||: binary concatenation.
ckbhash: Blake2b hash with CKB specific configuration, see Appendix.
to_le: Convert unsigned integer to bytes in little endian. The bytes count is the same with the integer width.
from_be: Convert bytes encoded in big endian to an unsigned integer.
molecule_serialize: Serialize a structure into binary using its schema.
eaglesong: See #todo rfc
compact_to_target: raw.compact_target encodes the difficulty target in a compact form. This function restores the target from the compact from.

The block is usually referenced by the header hash, for example, in raw.parent_hash.

header_hash := ckb_hash(molecule_serialize(header))

Notice that Header and RawHeader are all fixed size structure. The serialization of them are just the simple binary concatenation of the fields in order.

比较容易错的地方有两个

nonce 是按小端序放入 eaglesong input 的，且 raw hash 在前，nonce 在后
和 target 比较的时候，eaglesong output 是按大端序转成整数的

我用的版本是V0.31.1版本，所以这个版本上协议sumbit应该不是下列的方式吧
To ease PoW computation, the header is split into raw and nonce.

struct Header {
raw: RawHeader,
nonce: Uint128,
}

另外一个问题是，在最新版本v.32.0.rc-1上只有testnet采用plit into raw and nonce的方式， mainnet是还是沿用之前的结构。nonce包含在header里面，我的理解是只有在测试网的有变化？

0.32.0 testnet 改动是其它的，多加了一轮 blake2b。上面发的是相通的。分成 raw 和 nonce 是序列化层面的，RPC 里是摊平的。

Sorry, dev chain 默认是用的 dummy，我等下把调试信息贴出来

使用 dev 测试的话，需要修改 specs/dev.toml，把最后一行改成

需要修改 ckb.toml 填入矿工地址

[block_assembler]
code_hash = "0x9bd7e06f3ecf4be0f2fcd2188b23f1b9fcc88e5d4b65a8637b17723bbda3cce8"
args = "0x5406f5abe8e3...ba641f79556688c226d44631d"
hash_type = "type"
message = "0x"

args 改成 secp256k1 pubkey 的 blake2b hash

修改ckb.toml和dev.toml后dev ./ckb run还是一样的错误。
[block_assembler]
code_hash = "0x9bd7e06f3ecf4be0f2fcd2188b23f1b9fcc88e5d4b65a8637b17723bbda3cce8"

另外请帮忙在提交一下下面的rpc request看下校验结果是不是通过的，powhash<block target. 如果用这个提交校验还是能通过，我再找下问题可能的地方：

还是错的，你有比对中间结果吗？看日志 pow hash 是错的

可以用 https://github.com/doitian/ckb-sdk-python 对比测试一下

pip install -U ckb

There's also an example method to convert from block template to a block https://github.com/doitian/ckb-sdk-python/blob/master/ckb/block.py#L45

block = json.loads("""

谢谢 doitian, 我之前的理解是错误的，之前eaglesonghash(headerHashWithNonce)< blocktarget,我就去做submit_block, 正确的方法应该是eaglesonghash(ckb.header.pow_hash(block['header'])+nonce)<blocktarget 再做submit

dotian帮我确认一下我上述表述是不是正确的，现在我这样处理后测试矿机report上来的nonce值去校验全部>blocktarget..... (V0.31.1版本node的testnet)
