Alephium team started a project with aims to scale blockchains to handle tens of thousands of transactions per second [10,000+ TPS] in an open, permissionless network. And In late 2018, they achieved a peak throughput of over 10,000 TPS during tests of their Alpha version with consumer-grade AWS instances.
There are many team currently working on providing high TPS blockchains, but Alephium team is working on some additional features as well, but one particular feature is I liked is, it support for cross-shard transactions which provides a user experience, similar to single-chain platforms.
The details of the project and its features can be found at below article-
