Upgrade your nodes! https://github.com/algorand/go-algorand/releases/tag/v3.16.2-stable

Polkadot Developer Community - Official community forum to discuss Substrate, PolkadotJS, and building cross-chain dApps.

And of course you can always develop your own blockchain with Substrate to support it.

A great framework for building your own blockchain, and use numerous off-the-shelf modules, with Substrate - https://substrate.dev/

If you're interested in developing yourself, check out substrate.dev.

Assuming you are working through the substrate.dev tutorials I have just had this same problem as worked around it by reverting the node template to the `polkadot-v0.9.25` tag.

Well. Polkadot created substrate (substrate.dev) which is a framework for building a blockchain, with a lot of general components to make it easy to "plug-and-play" your customizable blockchain. I tried using their "Getting Started" guide to spin up "my own blockchain", it was done within an hour or so.

Check out https://substrate.dev/ !

Substrate is not a chain; it's the default address style, named after the Substrate development framework which virtually all (if not all) parachains are currently built with. https://substrate.dev/

Do contact the Substrate project (basis of the Polkadot/Kusama project), which is based in Berlin. You can contact them on their channel (see their website on http://substrate.dev), they're friendly and many of them are native German speakers.
