workshop: Understanding Cross-app Communication

[amgando]

Compare and contrast cross-app communication among NEAR, Polkadot and Cosmos platforms.

• NEAR Protocol's sharding relies on homogenous chunk-chains with a shared security model
• Polkadot's parachains are heterogeneous chains with a shared security model
• Cosmos' zones are heterogeneous chains with independent security models

@janedegtiareva, @chadoh and @mikedotexe -- does this seem like a worthy workshop goal that we can swarm on? I'm sure I will have a hard time trying to do this by myself but if we work together we may be able to produce something really compelling (and spot on topic for the RL1 conference)

NEAR these links do provide the needed technical input for NEAR

• https://docs.nearprotocol.com/docs/tutorials/how-to-write-contracts-that-talk-to-each-other
• https://github.com/near/near-sdk-rs/tree/master/examples/cross-contract-high-level
• https://github.com/near/near-sdk-rs/tree/master/examples/cross-contract-low-level

Polkadot these links may lead to the technical answer we need

• https://wiki.polkadot.network/docs/en/learn-bridges
• https://wiki.polkadot.network/docs/en/learn-parachains

Cosmos these links may lead to the technical answer we need

• https://github.com/cosmos/ics/blob/master/ibc/README.md
• https://github.com/cosmos/relayer

[mikedotexe]

I'm not going to commit at this time. 💙

@amgando certainly an interesting topic. Please let me know if I can help with anything.

Not sure what the best doc is for Polkadot.

This seems relevant

This sound like an interesting workshop to help create.
