Zcash T-addresses map - review and discussion

Hello, Zcash Mafia!

I’m working on a pet project that may be of interest to you:

Everything is still in test mode and so far, there is just balances for some large Zcash addresses that I have identified based on various types of daily activity. I have been able to verify some of them 100% as belonging to a particular holder, while others I have identified using non-trivial metrics that I will not disclose, but I’m not sure about their affiliation. And I haven’t verified several addresses with daily activity yet.

In the future, I hope to add analytics, but right now Zebra does not have full functionality for quick deep queries, and the data used in my tables is parsed into an external database, so I cannot add deep dynamics right away, but I will gradually learn how to do it. I am just getting started, and this project is not about advanced cryptography, of course, but it will probably allow us to draw some conclusions about the dynamics of the ZEC deficit.

By the way, you can help me verify other active addresses that I have not yet identified. It is not difficult at all. If you have interacted with any CEX-platform for the purpose of withdrawing ZEC, then simply check any such TX on withdrawal interface of your account in any block explorer (e.g., 3xpl) and send me the outgoing exchange withdrawal address as a note to this Zcash address:

Cool project! It’s great to be able to see quickly how they compare.

What functionality would you need?

What is the delta? Changes YoY?

Really cool! Might be an important dashboard to observe as the shielded pool is going Burj Khalifa :tokyo_tower:

Yes very cool project.

Maya is listing the following inbound address:
t1XWtaP3Diw8MKRejeWhNaiUBVbCtMmod3v

You can find it at the bottom here:

Not sure if it serves as outbound address as well.

Hello, Conrado!

Thanks for responding to this! I probably could have phrased the idea wrong, sorry, if it so, but I have encountered a lack of this method: getaddressdeltas

I found a mention here (Tracking: Block Explorer support · Issue #8435 · ZcashFoundation/zebra · GitHub) and concluded that this feature is in shipping.

BTW, I congratulate the entire Zebra team on the anniversary of the first commit.

Thank you! Yes, the delta shows the balance changes since midnight UTC at the current time.

I will add annotations as I go along.

getaddressdeltas is currently planned to be implemented in Zaino only. Not sure what the is the status there but you should eventually be able to use it if you run Zaino along Zebra.

Maya rotates these inbounds very often FYI, devs are expected to query the current list using the Midgard API every time before sending funds. A history of all inbounds previously used is stored in their blockchain.

Even with address rotation, it won’t be a problem to track :slight_smile:
It is currently working.

It was much more interesting for me to catch Grayscale’s addresses. I’m still not sure if I noted them correctly. I rely on data from Coinglass (Grayscale Bitcoin Trust ETF (GBTC) , Grayscale GBTC Premium/Discount, Grayscale Investments Holdings | CoinGlass) and I don’t know where they get it from to verify its accuracy. This week, one of the tracked addresses was replenished with 1,300 coins, but Coinglass does not show this. Although the holding company reflected other coins in its reports after a long (about two months) pause without any balance increases. Prior to that, these addresses and Coinglass data also had a temporary lag. Identifying correlations based on strange metrics is an entertaining form of analytics.
