There’s been a lot of buzz lately about #BitVM. But what 𝘪𝘴 it, exactly? How does it work?

And what does it mean for #Bitcoin?

Keep reading to find out! ⏬

BitVM is a new way to run complex programs on the Bitcoin network 𝘄𝗶𝘁𝗵𝗼𝘂𝘁 𝗰𝗵𝗮𝗻𝗴𝗶𝗻𝗴 𝗕𝗶𝘁𝗰𝗼𝗶𝗻'𝘀 𝗰𝗼𝗻𝘀𝗲𝗻𝘀𝘂𝘀 𝗿𝘂𝗹𝗲𝘀.

Normally, Bitcoin only allows simple transactions between addresses. But BitVM lets you run 𝗺𝗼𝗿𝗲 𝗰𝗼𝗺𝗽𝗹𝗲𝘅 𝗽𝗿𝗼𝗴𝗿𝗮𝗺𝘀 while still using Bitcoin's blockchain.

Here’s how it works:

1. Two people, Alice and Bob, want to run a program together on Bitcoin.

2. They translate the program into simple logic gates, such as “AND,” “OR,” and “NOT” gates. These are very basic building blocks of computation.

3. For each logic gate, Alice and Bob create a Bitcoin transaction. The transaction enforces that the gate's output matches its inputs.

4. They chain these gate transactions together to form the full program.

5. Alice and Bob exchange data off-chain to run the program step-by-step. Each step sets inputs for the next gate.

6. If Alice tries to cheat, Bob can challenge her on-chain. He forces Alice to run a certain gate transaction to prove she isn't lying.

7. After a few challenges, it becomes clear whether Alice was cheating. Bob gets both deposits if Alice cheated.

This allows for complex programs to be run on Bitcoin in a trustless way, without requiring a controversial soft-fork or risk changing Bitcoin's protocol. 🍴

𝗜𝘀 𝘁𝗵𝗶𝘀 𝘁𝗵𝗲 𝗮𝗹𝘁𝗰𝗼𝗶𝗻 𝗸𝗶𝗹𝗹𝗲𝗿? Well, anyone familiar enough with Bitcoin knows that it’s already superior to altcoins. Cryptos don’t need any help with dying. It’s all going to zero against Bitcoin. 💩

But for those wanting to build advanced, trustless applications on top of Bitcoin’s solid and truly decentralized foundation, this discovery could not have come at a better time. 🙌

What do 𝘺𝘰𝘶 think of BitVM? Let me know in the 𝗰𝗼𝗺𝗺𝗲𝗻𝘁𝘀! ⬇️

This is a historic announcement, so be sure to 𝗯𝗼𝗼𝗸𝗺𝗮𝗿𝗸 this so you can find it easily later.

Have any questions about it? 𝗔𝘀𝗸 𝗺𝗲! This is still a brand-new discovery, so there’s still more data for me to absorb, but I’ll give you my best answers.

Interesting. So can you give a more concrete example of how Alice or Bob might be incentivized to cheat each other while building a software program in the first place? This would help me understand the use case for running this program on the blockchain.

Sure! It depends largely on the specific program they're using, so let's suppose it's a program for decentralized gambling. Users would place bets on a certain outcome, and the program automatically pays out winnings based on the result.

In this scenario, Alice or Bob might be tempted to cheat by manipulating the odds in their favor. They'd be unable to do so, however, since the logic gates are permanently embedded in Bitcoin's blockchain, and can be publicly verified there at any time. The program could also be set so that any attempt to cheat would result in a loss of funds for the cheater.

BitVM's structure, with its transparent logic gates and on-chain challenge mechanism, is designed to deter such dishonest behavior, and ensure a level playing field for all participants.
