I am afraid to store my bitcoin in a multisig address.

In the future, if the Bitcoin protocol is updated, could there be any problems with multisig addresses? Are they safe to store bitcoin in for long term investments?

Is there any chance to lose my Bitcoin stored in a multibit address due to Bitcoin system updates/upgrades?

**Tags:** protocol, multi-signature, consensus, future-proof

Multisig transaction types use standard CHECKMULTISIG opcodes (which have been present in Bitcoin since its initial release in January 2009) and P2SH addresses (standardized in [BIP13](https://github.com/bitcoin/bips/blob/master/bip-0013.mediawiki) in October 2011). Both are very commonplace nowadays.
