bitcoind v23.0.0 supporting GBT/append ?

[citb0in]

Hello all,

does the latest version of bitcoind support GBT/append?

(A) I can get the blocktemplate easily with

Code:

bitcoin-cli getblocktemplate '{"rules": ["segwit"]}'

For getting the template with coinbase/append support according this information it needs

{"id": 0, "method": "getblocktemplate", "params": [{"capabilities": ["coinbasetxn", "workid", "coinbase/append"]}]}

(B)
I am trying to get this template with

Code:

bitcoin-cli getblocktemplate '{"params": [{"capabilities": ["coinbasetxn", "workid", "coinbase/append"]}]}'

error code: -8
error message:
getblocktemplate must be called with the segwit rule set (call with {"rules": ["segwit"]})

(C) However, when trying to combine those two

Code:

bitcoin-cli getblocktemplate '{"rules": ["segwit"], "params": [{"capabilities": ["coinbasetxn", "workid", "coinbase/append"]}]}'

I get the same output as I got in (A). How?

params is not a valid component of the template request. It looks like you are conflating the way that JSON-RPC sends parameters with the actual parameters themselves. Your command should actually be:

Code:

bitcoin-cli getblocktemplate '{"rules":["segwit"], "capabilities": ["coinbasetxn", "workid", "coinbase/append"]}'
