Perhaps it's not that crazy. There's a long history of entities being paid to not perform certain activities that they provably otherwise could. It all comes down to financial incentives.

Could BTC migrate to Cardano?
# Could BTC migrate to Cardano?

(Asked by: username_0 on 2021-10-01)

According to [research by the University of Cambridge](https://cbeci.org/), the Bitcoin network currently consumes around 100 terawatt-hours of electricity annually, enough to run a [country such as Sweden](https://iohk.io/en/blog/posts/2021/08/17/why-they-re-calling-cardano-the-green-blockchain/).

The second largest crypto-currency, Ethereum, [suffers from similar energy problems](https://digiconomist.net/ethereum-energy-consumption).

Given Cardano's amazingly low energy consumption, coupled with the recent success of making the blockchain [carbon neutral](https://cardanofoundation.org/en/news/how-green-can-the-cardano-community-make-cardanos-blockchain/) (see [Cardano forest](https://ito.veritree.com/)), would it be possible to move $BTC to the Cardano network and, if so, **what would be the exact process?**

Also, putting aside the interests of Bitcoin miners, **what impacts would Bitcoin users experience and how could these be minimalised?**

(I'm exploring these questions, and more, at <https://twitter.com/cardanoclimate>)

## What would be the exact process?

*Beware: I'm not certain this answer is correct (specifically whether an ouroboros sidechain could have $BTC as a UIA and the specifics of how the Bitcoin network would migrate across to using it).*

Looking into this, Bitcoin could exist on Cardano as a [sidechain](https://web.archive.org/web/20201203201330/https://why.cardano.org/en/introduction/sidechains/) with $BTC as a User Issued Asset ([UIA](https://web.archive.org/web/20201203200004/https://why.cardano.org/en/introduction/uias/)). The nice thing about using Cardano sidechains is that transaction fees could still be in $BTC (instead of $ADA).

As to the *exact process* for achieving a migration, the answer lies with [Ethereum's move to proof of stake](https://web.archive.org/web/20210605140949/https://consensys.net/blog/blockchain-explained/charting-the-path-to-proof-of-stake-ethereum/) and "the merge".

The transition process would require the consent of client developers and exchanges in order to accept the changes. Consent of miners does not appear to be required.

However, Ethereum only exists due to Bitcoin's inability to evolve and make substantial changes. Unless something very significant changes in the Bitcoin world, it seems extremely unlikely that Bitcoin would attempt to chart a similar course. In addition, with so much money invest in equipment, mining would undoubtedly continue on a fork (similar to Ethereum Classic) raising the question of what would really be achieved.
