Zil is not the only one project which has sharding. For example Pchainans some other projects have sharding too. They should compare all projects.
There are posts on the first page of this thread where you will find comparisons to other projects and not only Zilliqa.
I can understand to miss a few pages when a thread is long but this one has only a few comments so far.
I would suggest developing a habit to read first at least 70% of the thread before posting.
Not only this saves you from many mistakes but there is a big chance that you will find something interesting and write a high-quality post because of it.
Back to the topic.
Elrond is a very interesting project and I ask myself why this thread caught almost no attention from reputable members?
Already a few months on the market and looks very professional. If roadmap would be delivered without delays we can find Elrond in top 10 on CMC very fast but still no attention from Bitcointalk community.
