Public pool no longer works since Bitcoin core 28.0

Hello, Public pool no longer works on umbrel home since the update of Bitcoin core 28.0.
Is an update planned?
Greetings.

Same problem…

There’s a change in Bitcoin Core 28.0: The JSON-RPC server now supports JSON-RPC 2.0. It recognizes JSON-RPC 2.0 requests and responds in strict accordance with the specification.

Public Pool may need to be updated to be compatible with the new JSON-RPC server.

I’m sure the Umbrel team has this on their radar.

Ok thanks! Let’s wait then.

Thanks for reporting this @Badreality and @denny.

Looks like the Public Pool project is using this rpc-bitcoin library that passes jsonrpc as a number instead of a string:

github.com

vansergen/rpc-bitcoin/blob/ace0f6889d2454c741600bd2a85de410ca494f1d/src/rpc.ts#L413


      
            this.fullResponse = fullResponse ? true : false;
            this.wallet = typeof wallet === "string" ? wallet : undefined;
          }
          
          batch(body: JSONRPC | JSONRPC[], uri = "/") {
            return super.post({ body, uri });
          }
          
          async rpc(method: string, params = {}, wallet?: string) {
            const uri = typeof wallet === "undefined" ? "/" : "wallet/" + wallet;
            const body = { method, params, jsonrpc: 1.0, id: "rpc-bitcoin" };
            try {
              const response = await this.batch(body, uri);
              return this.fullResponse ? response : response.result;
            } catch (error) {
              if (error.error && error.error.error && error.error.result === null) {
                throw this.fullResponse ? error.error : error.error.error;
              }
              throw error;
            }
          }

Which is failing now that Bitcoin Core v28 is strictly adhering to JSON_RPC specs.

Edit: looks like Public Pool just merged the fix

Could I please get anyone that comes across this post to add a reaction to this github comment here so that Public Pool devs see the need to quickly update their code:

Comment by nmfretz - patch rpc-bitcoin to be compatible with bitcoin core 28.0

benjamin-wilson:master ← remcoros:patch-rpc-bitcoin

Thanks for this workaround @remcoros. I just went down a rabbithole after updati…ng Core to v28 and tracked the issue down to the `rpc-bitcoin` library which seems to be a dead project at this point. @benjamin-wilson do you have a timeline for testing+merging this and pushing an updated docker image? Public Pool is in the Umbrel app store and it would be great to update it with official docker images that maintain compatibility with Bitcoin Core v28. But if this is still a ways away I can just build an image to temporarily get Umbrel users back up and running until a new official image is released.

If an official update from Public Pool does not look imminent, then I can fork the project, merge the fix, and build a docker image to get Umbrel user’s back up and running temporarily until an official docker image is released.

Seeing the same issue. Do you access the Public Pool logs on Umbrel?

nmfretz · October 31, 2024, 11:17am

Hey all. A Public Pool update just went live with a fix for Core v28 compatibility. Just click update when you see it come through and you’ll be all good to go.

Thanks for the reports and your patience.

Alf · October 31, 2024, 11:39am

Hi Nate
Thanks very much for the fix. The solo miners are back in action.

denny · October 31, 2024, 12:09pm

Amazing! That was speedy. Everything’s back to working perfectly now!

DenebGalaxy · October 31, 2024, 8:48pm

Is there any chance you could add CKPool to Umbrel as an alternative option? Why? Because Avalon Nano3 basic miners do work properly with Public Pool. When I connect them (everyone who owns Nano3) the pool starts registering hashrate but then drops it and shows zero hashrate as well as 0 best share… Would be great to have CKPool that is also publicly available and free to have on Umbrel. Thanks

Way to go team!

Badreality · October 31, 2024, 11:38pm

Update ok in umbrel Home.
Everything works great.
Thanks everyone!
