To Wrap Bitcoin Or Not Wrap Bitcoin

Let’s talk about bitcoin in crypto. Not all of it is the same. You have probably seen BTC, WBTC, CBBTC, WRBTC, and SBTC. What is the difference, what should you consider, and why does this exist?

BTC is bitcoin

BTC is the purest form. It is bitcoin. Every other form is trying to create an image — a copy — of bitcoin on a different blockchain: Ethereum, Base, Rootstock, or Stacks. There are side systems out there too.

Why do they do this? Bitcoin is first, and the most sought after. You should ask why. That answer is a thread of its own. Anyone entering crypto has to go down the rabbit hole of why bitcoin, what decentralization is, and why proof-of-work mining. That should be the first task. Satoshi Nakamoto created this innovation — blockchain — with decentralization, cryptographic proof, and no third-party systems or entities.

Other blockchains do not exhibit the same principles, values, and architecture as original bitcoin. They will never be able to recreate that purest form. They do not have a time machine. Blockchains get stronger with time: blocks of data linking to prior blocks. The longer the chain, the more secure. Architecture and the network itself play a large role too.

Which image is closest?

Given that, you have to ask of these wrapped or different flavors of bitcoin: which aligns most closely with the original principles? That is critical, because these images run on a different network, with different principles.

Walk into a casino to play blackjack. You go to the cage, hand them your cash — bitcoin, in this example — and they hand you a chip that represents that value. Those chips are the other blockchain. The chips have different qualities. They can only be used in certain places. There is a process of exchange, cash to chips and chips to cash. There is a different custodian that controls the issuance and creation of chips. In short, it goes to the same questions I posed in Stable Coin Factors: governance, mining mechanisms, and the rest.

Investigate those factors before you park bitcoin on a different chain.

Why people wrap it anyway

Bitcoin is a large battleship. It packs a punch. It is powerful. It is slower, and it takes a long time to turn when it is time to pivot. It is also limited in how it can be customized. That is fine. It is working as intended. We love bitcoin as it is today, and I would not change a thing. There is tremendous value in the present form.

People who want to do things with their bitcoin seek these other versions for DeFi, ecommerce, DAOs, NFTs, AI, and the rest. They may want lower fees and faster transactions. They want a programmable world with their bitcoin, and they want to stay on-chain. They do not want to move BTC onto antiquated systems where a custodian or entity is involved and can smother the inherent principles.

Study all of it. Personally, I believe staying on-chain is best. I also believe sBTC on Stacks possesses the principles most closely aligned with L1 bitcoin: programmability, security, and speed.
