Using multiple versions of secp256k1 implementations, the time required to verify the signature is as follows.

ECDSA	libsecp256k1 in c	libsecp256k1 in cgo	secp256k1 in go
Sign	46000ns	92138ns	81926ns
Verify	69200ns	151701ns	236794ns

Compile with go-secp256k1

make tools install

Cross-platform compilation: make tools install build-linux

Testnet binary compilation: IS_TESTNET=true make tools install

Compile with c-libsecp256k1

If you want the node to run faster, the following command is recommended for cgo compilation。

Compile libsecp256k1

TENDERMINT_VERSION=`grep tendermint/tendermint go.mod | sed -E 's/(.*) (v[^ ]*)/\2/g'`
SECP256K1_PATH="$GOPATH/pkg/mod/github.com/tendermint/tendermint@$TENDERMINT_VERSION/crypto/secp256k1/internal/secp256k1/libsecp256k1"
