Hey guys, second whitepaper that I am sharing. This is something we have been working on at Bitfinity for a while now - the problem we are trying to solve is how to integrate tokens from a bunch of different ecosystems on the EVM.

As usual, thought and comments are welcome. [whitepapers/BitFusion.pdf at main · bitfinity-network/whitepapers · GitHub](https://github.com/bitfinity-network/whitepapers/blob/main/BitFusion.pdf)

Some commentary on what makes a Layer-2.

Here’s a cool table from the preparing comparing Bitfinity/IC to other BTC L2s. Standing on the shoulders of giants.
