Symbol blockchain news update – 21/01/22

Very short post today but I saw some interesting news on Discord that I thought that I should report on.

Valkyrie

Looks like this hasn’t been tweeted about yet as there are some final formalities that still need to be addressed but it seems like the Valkyrie partnership is happening and hopefully will be signed off and official soon! 👏

The riddler

I like puzzles and have to admit I had a head start on this one after the previous challenge (although I did provide code in the article so no excuses people 😁). The task was to assemble three different PNGs from transactions listed and then look at how they differ.

You can see that the three images are very similar when recombined from the transaction messages. In fact, the image data is identical even though they look distinct. Looking at this in more detail I realised that the only difference is in the PLTE block which controls the colour palette of the image. Check out these awesome animated examples here – they really are impressive!

This is super cool as it means that most of the data is redundant, to assemble images two and three you only need the IDAT image data (which is large) from the aggregate of the first transaction from image 1 along with additional transactions containing only the PLTE block which are specific to image 2 and 3. This makes the IDAT reusable – you only need to store it once and it can then be reused. I noticed this morning that Gimre explains this far better than I do in this follow up thread – give it a read!

And goddammit there is another task in this thread 🤬 I don’t have any time this weekend! Maybe I will give it a go next week if I have time and nobody else has solved it yet 😊

New exchange listing

Looks like XYM will be getting a new exchange listing on BTCEX Japan. Again this just highlights the strength of support, popularity and community in Japan. I guess for us to see listings on western exchanges we need to start showing the same enthusiasm for Symbol as our Japanese friends.

Thanks!

Thanks for reading. Again, apologies for the short update today. Just wanted to report on the Valkyrie news and the updated puzzle task! Now back to work 😬
