# One-Way Interoperability

### The Need for Cross-Chain Communication

Blockchains that have no interoperability with other networks suffer from **community isolation**. 

*Leading to...*

* Limited liquidity pathways
  * Crypto-to-crypto on and off ramps are non-existent
  * The UX of token access limits value
* Ecosystem lock 
  * Holders can't cross-pollinate 
  * DeFI utility is bounded
  * Tooling applicability is restricted
* Resilience
  * Single chain ecosystem is fragile

### The problem with interoperability frameworks

*Inter-blockchain communication frameworks and standards like Wormhole and Cosmos' IBC  have:*

**Two-way, permissioned integration architecture:** 

1. Both communities need to agree on a protocol and standard
2. Both chains must update their source code to be able to interpret cross-chain messages
3. Chains become dependent on another's security
4. Is a consensus-breaking change that requires a governance action on both sides
5. Is complex to build due to race conditions caused by two block times

**And often require...**

Dedicated actors and trust assumptions like:

1. Third-party oracles
2. Cherry-picked validators
3. Off-chain relayers
4. Centralized guardians
5. Altruistic light client runners

**Resulting in...**

1. Extra gas fees
2. Limited throughput
3. Wrapped (synthetic) assets
4. Cost inefficiencies

### Permissionless Interoperability

Canopy employs the first instance of 1-way - permissionless interoperability:

* ✅ only the Canopy chain's governance needs to agree on the new feature
* ✅ only the Canopy chain needs to update their source code
* ✅ interoperability features are composable and may be re-used by any Canopy chain
* ✅ security is still 100% self-reliant
* ✅ far less complex to build as no block-time race conditions
* ✅ trustless BFT agreement, no "trust minimization"
* ✅ no centralization, no off-chain actors
* ✅ no extra fees
* ✅ scalable, sovereign, without inefficiency

**Canopy's 1-way interoperability means that multi-chain features can be built simply and without the permission of the 3rd party chain.**

**This means:**

* Ecosystem-locked businesses and apps may be 'rescued' by the Canopy chain
* There's limitless ecosystem expansion
* Stablecoin on-ramp plugins are reusable across all Canopy chains, enabling instant liquidity 
* Cross-chain collaboration is fostered without effort on any incumbent, enhancing overall adoption and usage of Canopy
* External chains can remain sovereign, while benefiting from Canopy's security and infrastructure
