## README

### 目录结构
```
<WorkingDir>
|- lotus
|- rust-fil-proofs
|- bellperson
```

### 获取源码
```
git clone https://github.com/filecoin-project/lotus.git
cd lotus
git submodule update --init --recursive
```
### 更新 extern/filecoin-ffi
```
cd extern/filecoin-ffi
git pull origin master
git checkout d828994
```
### 修改 extern/filecoin-ffi/rust/Cargo.toml
```
[dependencies]
...
bellperson = { version = "0.13", default-features = false, features = ["gpu"] }
...
[dependencies.filecoin-proofs-api]
package = "filecoin-proofs-api"
version = "~6.1"
default-features = false
features = ["gpu2"]
...
[features]
default = ["pairing", "gpu2"]
...
[patch.crates-io]
bellperson = { path = "../../../../bellperson" }
filecoin-proofs-v1 = { package = "filecoin-proofs", version = "~6.1", default-features = false, path = "../../../../rust-fil-proofs/filecoin-proofs" }
filecoin-hashers = { version = "~1.1", default-features = false, features = ["poseidon", "sha256"], path = "../../../../rust-fil-proofs/filecoin-hashers" }
fr32 = { version = "~0.2", default-features = false, path = "../../../../rust-fil-proofs/fr32" }
storage-proofs-core = { version = "~6.1", default-features = false, path = "../../../../rust-fil-proofs/storage-proofs-core" }
```

### 修改 Makefile
```
#git submodule update --init --recursive
#@[[ "$$(awk '/const Version/{print $$5}' extern/filecoin-ffi/version.go)" -eq 3 ]] || (echo "FFI version mismatch, update submodules"; exit 1)
```
### rust-fil-proofs
```
git clone https://gitee.com/olier/rust-fil-proofs.git
cd rust-fil-proofs
git checkout z-6.1.0
```
### bellperson
```
git clone https://gitee.com/olier/bellperson.git
cd bellperson
checkout z-0.13.0-3080
```
### 修改文件，旧版bellperson没有下面几个方法
```
sed -i 's/ffi /\/\/ ffi /g' extern/sector-storage/ffiwrapper/prover_cgo.go
sed -i 's/return ffi.AggregateSealProofs(aggregateInfo, proofs)/return nil, nil/g' extern/sector-storage/ffiwrapper/prover_cgo.go
sed -i 's/return ffi.VerifyAggregateSeals(aggregate)/return true, nil/g'  extern/sector-storage/ffiwrapper/verifier_cgo.go
```
### 编译
```
cd lotus
make clean all lotus-bench
```

### 测试
```
./lotus-bench sealing
```
