Discussion Thread for "cross chain validation"
This thread is to discuss definition and functionality of “cross chain validation”, aka, shared security. Below is our version of definition. We can start discussion from this definition. • naming of the protocol • shared security, delegated security • security is too broad wording • does not explain the characteristic of interchain protocol • does not represent the fact that it is an application on IBC • interchain collaterization • interchain seems adaquate wording to explain that it is a protocol between different chains, and also it implies it is an application on IBC • collaterization seems too broad concept compared to what it really serves because many defi applications also use the word collaterization in different range • cross-chain validation • cross-chain and interchain seems very similar description • the word validation seems correctly describe the role of the protocol • conclusion • we will use the word “cross-chain validation” as now • naming of each blockchain • leader/follower chain • the roles are not related to front and behind so it is not adaquate • control/controlled(?) chain • the role is to…

Let me describe some points to discuss • which chain to confirm the entire validator set? • child chain : mother chain validator set info is relayed to child chain. Entire child chain commit the entire validator set on child chain. • mother chain : child chain validator set info is relayed to mother chain. Only mother chain validators commit the entire validator set on mother chain • periodic heart beat • if the child chain cannot get mother chain validator set info for predefined number of blocks, entire validator set info in child chain can be recognized as old info, so we need a safety stop to prevent problems caused by significant power changes in mother chain • mother chain validators operate full-validator of child chain to participate • they should operate full-validator binary to verify all txs and state changes, just same as the responsibility of child chain validators • cross chain reward distribution • option1 : interchain reward transfer happens only when a delegator withdraw rewards • option2 : entire rewards periodically transferred to mother chain and withdrawal happens for each request on mother chain • validators in…
