The chart visualized on Blockchair doesn’t precisely show the daily sizes committed to Zcash each day. ![image](https://global.discourse-cdn.com/zcash/original/3X/d/7/d704104aa8226de6157beb12163052158c03a4a9.png) > **[Create custom charts](https://blockchair.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)** > > Use Chart constructor to create custom charts, plot up to two data types from any of the 10 blockchains, apply custom filters and functions It is slowing down a bit ---

I’m also very concerned about this issue, so I asked @daira about how quickly we can observe the effect of ZIP 317. > Thus, this thing has a network effect and theoretically a spammer can be looking for nodes that will skip his transactions with low fees (if I understood everything correctly). So far, we have just about 1/3 of the nodes switched to 5.5.0 and the graph seems to correlate with this. ---

The EOS height for 5.4.2 should be around the beginning of July-ish, didnt calculate the actual date, just roundabouts ---

End-of-support heights are given here: [Release Support - The zcashd Book](https://zcash.github.io/zcash/user/release-support.html#end-of-support-heights) For 5.3.3 and 5.4.2 (which were released at around the same time), the approximate EoS date is 2023-06-13 — so mid-June, not July. 5.5.0-rc1 did include the ZIP 317 block construction change. ---

By the way I strongly recommend that people not use that Blockchair chart creator. It has a bug that causes only part of the graph to be rendered, giving seriously misleading results. Specifically, the rendered line is some scaled version of _part of_ the actual line, but it does not necessarily match the ranges of the axes (on mobile, this may even depend on what orientation you hold your phone in). ---

did you ever research the possibility of turning Zcash to a 50 KB Bockchain like Mina? i think it could be the killer app of Zcash ---

Perhaps this was tad dramatic? Still here, still running, and HW prices keep going down. What am I missing? ---
