One of the main challenges for Bitcoin Chains is to keep a balance of inbound and outbound funds between Chain and Bitcoin. This applies to both deposit (peg-in) transactions and withdrawal (peg-out) transactions. If these flows are not managed - the system will quickly develop an asset imbalance with the emergence of double-spending transactions and conflicting inputs. Botanix gracefully solves this with Spiderchain. Botanix's Spiderchain is a federated Proof-of-Stake chain for Bitcoin, built on a rotating multi-signature wallet structure.
