Byte size of cosmos address/public key/signature

Archived Cosmos-SDK

Hi,

I’m using cosmos-sdk for one of my projects. I want to know the number of bytes in cosmos address, public key and signature. Can someone please let me know if you know details about this.

Thanks

Cosmos addresses are always 20 bytes/160 bits.

Cosmos public keys depend on the type of cryptography used. The scheme uses secp256k1 keys by default which are 33 bytes.

Signature are genereally 64 bytes.

Thanks @zaki

Cosmos uses Bech32 encoding for addresses, will this change the size of the addresses and public keys?

bech32 is just we encode values when displayed to humans, it doesn’t affect size on disk/ wire.
