Hi, you mentioned about full nodes. What is the defination of a full node?
According to the docs (https://developers.libra.org/docs/welcome-to-libra#the-libra-ecosystem), there are clients and validator nodes. What’s the difference between a full node and a validator node?
Hi, @729. That is a very good question, and I’m glad you asked. There will be a full blog on this out soon.
In the meantime, a validator node is a node run by a member of the Libra Association, and it validates transactions as part of the consensus process. It accepts transactions from clients and inserts them into the Libra Blockchain. It’s focused primarily on writes.
A full node can be run by anybody. It validates transactions as a part of synchronizing the Libra Blockchain from validators. And it’s focused primarily on reads.
Look for the detailed blog soon!
What is “Libra Wallet Ecosystem” in Exit Criteria specifically mapped for technical association members?
btw, I checked the blog of Bison Trails which helped me figure out blind spots i did not even notice.
@tommyyama2020 Thanks for the feedback on the Bison Trails blog! And, we’re tracking down an answer to your question (with the holidays, we might be few days behind).
There are many variations on Nodes, and many factors to how theyre implemented, but personally all i wanna know is WHEN? lol
This is just a category for the items that need to be implemented in code in support of products built on top of Libra like wallets.
I’d appreciate your kindness answering. 
As speculated in the news, can we expect the launch in the second half of the year?
I am willing to bet you won’t get an answer. Libra Association members probably don’t talk about features and release dates.
Thanks greg for answering my question. LOL
Hope you had a great holiday and we catch up at the end of Jan! 
Hi,
When will Libra release the wallet? and When will Libra release the Smart contract?
the roadmap is too summary, and lacking the timeline on it.
Thanks
@pkubear Thanks for the questions. The Libra Association is looking to developers in its community to build wallets that work on the Libra Blockchain, and does not plan to build its own at this time. If you look in the What I Made topic in this community, you will see a number of examples there. As for smart contracts, we do not currently have a date announced.
Why not just adopt mimble-wimble? Although I am running the test-net on my machine and wallet seem’s to function well but why not just fork mimble-wimble with atomic swaps feature in wallet?
mimble-wimble and other blockchain confidentiality mechanisms are interesting . As the Libra Association is subject to regulatory oversight, new features such as these would need to be discussed and agreed upon with regulators prior to any progress in this direction.
