Multisig in 35 seconds. First animated entry in our glossary.

Multisig is a Bitcoin wallet pattern where spending requires multiple signatures, not just one. Three keys held in three places, any two can sign. The animation walks the threat model end to end in 35 seconds.

What it shows:

- Setup: three keys with a "Three different makers" caption. Vendor diversity means a bug in one firmware can't break the others.

- Normal spend: two of three keys sign, transaction broadcasts.

- Loss scenario: one key is gone (lost, destroyed, custodian closed). The other two still sign and the spend goes through.

- Theft scenario: a thief takes one key. They can't sign alone multisig halts at "1 of 2." A single stolen key is worthless without one of the others.

- Closing pillars: Multisig. Threshold-of-keys. Vendor-diverse.

This is the first animated entry in the LearnBitcoin.com glossary. The rabbit-hole series already had animations on chapters like mempool and lightning routing; this brings the same treatment to glossary terms that deserve a visual.

We will add more over time, would love suggestions on where you think our style of animation can bring clarity to complex bitcoin topics.

Open source. Bitcoin only. No bullshit. Have fun.
