I would change the type of n to uint to satisfy your condition at L211 as n can not be negative. I think, there is an idiomatic way to declare multiple variables inside FakeKey like that:

var (
     key = ...
     keys = [100]*ecdsa.PrivateKey{
)

Okay, I write code to generate this code segment so didn't notice this

I would change the type of n to uint

idx.ValidatorID type actually is uint32 to I changed the type of n to uint32 as well

Wondering if these will work:

var seed = []byte("163f5f0f9a621d72fedd85ffca3d08d131ab4e812181e0d30ffd1c885d20aac73144c0aa4ced56dc15c79b045bc5559a5ac9");

.......

// FakeKey gets n-th fake private key.
func FakeKey(n uint32) *ecdsa.PrivateKey {
if n == 0 || n > 100 {
panic(errors.New("validator num is out of range"))
}

// shift left n characters of the seed to the end
var shifted = string(append(seed[n:], seed[:n]...))
// and get the first 64 bytes
var k = "0x" + string(shifted[:64]);

var key, err = crypto.ToECDSA(hexutil.MustDecode(k))

if err != nil {
	panic(err)
}

return key

}

Yes, I think it might work but we want to keep the fakekey as same as when running below code on old version of golang. So we pre-generated all the first 100 keys from old version of golang and hardcode into the source like that.

	reader := rand.New(rand.NewSource(int64(n)))

	key, err := ecdsa.GenerateKey(crypto.S256(), reader)


key, err := ecdsa.GenerateKey(crypto.S256(), reader)
if err != nil {
panic(err)
if n > len(keys) {
panic(errors.New("validator num is too large"))
}

return key
return keys[n-1]
}
