Been looking in the $iota ecosystem more lately.
The progress in the past few months been HUGE for Enterprise DLT.
From establishing in Abu Dhabi to building trade solutions in Africa with WEF.
They're one to watch for the long term.
The network architectures quite unique in itself through the Tangle's ability for transactions to verify other transactions on the network.
Simply put, each transaction validates 2 other transactions that are sent.
Thus creating an endless chain of trust.
As the only way for your transaction to go through is by verifying the 2 other transactions in the chain.
The biggest benefit to this model is that it's feeless & provides a Network Effect where the more transactions are submitted, the more transactions are verified by one another.
In terms of use and adoption, we've seen $IOTA connect with government entities & F500s alike.
