Scalability has been and will continue to be one of the biggest problems for most existing blockchain technologies. There are various projects that are currently having a crack at solving the whole scalability issue through various innovative methods like moving information off-chain, Aeternity being a prime example in this case.
Zilliqa is another, very relevant project that aims to tackle the problem of scalability by revolutionizing the technology behind sharding. It does so by implementing a sharding solution that scales with the network’s size via a method called linear scaling.
This means that, at least in theory, there’s no limit to the number of transactions that the platform could process per second. Also worth knowing is the fact that Zilliqa aims to support smart contracts, even though this mission is very challenging on a sharded network.
