Due to the lack of network effect, these isolated blockchains won’t stand a chance against attacks. The TWC is almost certainly not the perfect solution, the accompanying paper provides details on a number of vulnerabilities inherent to notary based solutions. However, while the TWC is not the perfect solution it is a good solution aion ico to motivate inter-blockchain dApp development. Developers may begin to design and build a new class of dApps focused on leveraging multiple blockchains. Eventually the perfect solution may be developed and messages may be routed between chains differently however following the TCP/IP design application semantics remain the same.
