`3yANa` addresses
The g1 and gtest blockchain store accounts with bad addresses in the genesis (wrong prefix, **3yAN** instead of **g1**).
Strangely, le prefix number is good : 4450!
```python
from scalecodec import ss58_decode
ss58_decode("3yANbqMMjVitdsoyibuYv7GmEERfvgGWyeoewTBMtS6rCr29jSw", 4450)
'02770ec8f78a23995f4ad45c20b7f363e58f6603c1f2c7c2dbf80af9c24a505a98'
```
But the length of the public address is wrong:
```python
ss58_decode("3yANbqMMjVitdsoyibuYv7GmEERfvgGWyeoewTBMtS6rCr29jSw", 4450)
'02770ec8f78a23995f4ad45c20b7f363e58f6603c1f2c7c2dbf80af9c24a505a98'
len('02770ec8f78a23995f4ad45c20b7f363e58f6603c1f2c7c2dbf80af9c24a505a98')
66
```
A good address has a length of 64 bytes:
```python
ss58_decode("g1Jz9MNpRPEP656r1mW3aMtnaiqTro65Cfq9FnQjsaCoViawH", 4450)
'00492ab849cfef6fee6a9ab4b83e6a985c8693576d67bafa4ad1709ae0d9d4df'
len('00492ab849cfef6fee6a9ab4b83e6a985c8693576d67bafa4ad1709ae0d9d4df')
64
```
