Sidechains - The Z Amigos
(B1 1000+)
Using the above features (i.e. forks, asset locks, ZSA-addresses) should be enough to create 3 sidechains. I advocate that sidechains are probably the most powerful feature a zk-proofs chain can have. Optionally these sidechains could be self funding. Fees for transactions on sidechains can not only fund nodes and the cost of merging but also contribute for future maintenance/development.
ZCompute
This sidechain will enable user defined contracts. These contracts will allow the user to programmatically control how and when transactions occur.
ZRollup
This sidechain will enable anonymous groups of users to aggregate their transactions. This enables users to transfer their assets at a much cheaper rate.
ZLend
This sidechain utilises the fork asset locking functionality. These locked assets can then be used as collateral for other assets.
° the dependencies (e.g. fork, consensus callbacks, asset locks, and ZSA-addresses) haven’t been included in costing. But given these side chains themselves pose no risk to main chain consensus I believe all 3 of this could easily be beta’d in 1000+)
