0. 根据自己本机环境选择是否需要提供的脚本进行各种依赖的安装（node、yarn、git、rust、circom、snarkjs）

1. install：

   yarn install

2. 进入 packages 目录：

   cd packages
   chmod +x *.sh

3. 进行setup：

   ./setup.sh
   ./setup.sh pick-two demo-zk-email-two build-two
   ./setup.sh pick-three demo-zk-email-three build-three

4. 使用官方snarkjs生成proof(单进程、多进程)：

   ./generate-proof.sh
   ./generate-proof.sh pick-one demo-zk-email-one build-one proofs-one 10 parallel 3
   ./generate-proof.sh pick-two demo-zk-email-two build-two proofs-two 1 serial
   ./generate-proof.sh pick-two demo-zk-email-two build-two proofs-two 10 parallel 3
   ./generate-proof.sh pick-three demo-zk-email-three build-three proofs-three 1 serial
   ./generate-proof.sh pick-three demo-zk-email-three build-three proofs-three 10 parallel 3

5. 安装rapidsnark：

   ./rapidsnark-install.sh

6. 使用rapidsnark生成pick-one电路的proof：

   ./generate-proof-with-rapidsnark.sh

7. 使用官方snarkjs生成proof(多线程)：

   npx ts-node generate-proof-parallel.ts
   npx ts-node generate-proof-parallel.ts --working-dir pick-one --thread-num 2 --iteration-num 2
   npx ts-node generate-proof-parallel.ts --working-dir pick-two --circuit-name demo-zk-email-two   --build-dir build-two --output-dir proofs-two-parallel --thread-num 2 --iteration-num 2
   npx ts-node generate-proof-parallel.ts --working-dir pick-three --circuit-name demo-zk-email-three --build-dir build-three --output-dir proofs-three-parallel --thread-num 2 --iteration-num 2

8. 其他电路请参考脚本开头注释

yarn install v1.22.22

禁用SSL检查即可，因为是临时测试demo，无需严格SSL yarn config set strict-ssl false

先限制 node 进程使用的内存大小 NODE_OPTIONS=--max_old_space_size=32768 再设置系统内核参数，调整进程能创建的内存映射区域数量，将默认值放大10倍吧 sysctl -w vm.max_map_count=655300 && sysctl -p 引用：https://hackmd.io/V-7Aal05Tiy-ozmzTGBYPA?view
