Building Bitcoin Supercharged Networks

Bitcoin Supercharged Networks (BSNs) are a type of blockchain that uses Bitcoin as the underlying security layer or additional security layer.

Cosmos Chains​

Cosmos chains can integrate with Babylon to get security from BTC stake. This is made more important for new Cosmos chains with less staking TVL. In addition, the staked BTC achieves slashable safety, a strong security property that the equivocations by BTC-backed Finality Providers are held accountable, even when equivocating Finality Providers constitute a majority.

OP-stack Chains​

OP-stack chains can integrate with the Babylon BTC staking protocol to get Bitcoin security.

This has a few benefits:

  • Better economic security: There is native BTC staked to protect the rollup and improve its economic security. This is made more important for new OP-stack chains with fewer adoption. In addition, the staked BTC achieves slashable safety, a strong security property that equivocations by L2 sequencers are held accountable and the BTC stake is slashable, even when equivocating L2 sequencers constitute a majority.
  • Fast finality: The improved economic security will benefit the OP stack chains for fast finality. If the user is willing to trust the votes backed by the BTC stake, then the user can confirm transactions and make decisions without waiting for the lengthy challenging period in optimistic rollups.
  • Reorg resilience of L2 transactions: Once a transaction is included in an L2 block signed by the majority of BTC-backed Finality Providers, the sequencer cannot publish a different L2 block at the same height on L1.
