Issue on claim-on-sidechain in sidechain-manipulation.py about elements

[instagibbs]

For the first issue the newest version of elements should have this fixed. #79 (mismatch between libsecp version and this tool)

https://github.com/Blockstream/contracthashtool/pull/8/files?diff=split

It was merged 5 days ago.

re:connections, what does getpeerinfo tell you?

Hi instagibbs,

I have pulled the latest contracthastool to the newest version, but the error still remained. I've tried both libsecp from ElementsProject and from the the libsecp github site. Do I need to do send to sidechain another btc to claim it? I kept the alphatestnet3 the same, did not remove the wallet.dat in it.

Here is the info when I typed alpha-cli getpeerinfo

[ { "id" : 1, "addr" : "162.243.132.6:4242", "addrlocal" : "170.252.244.1:62213", "services" : "0000000000000001", "lastsend" : 1455547061, "lastrecv" : 1455547064, "bytessent" : 1925, "bytesrecv" : 2291, "conntime" : 1455547060, "pingtime" : 0.44494400, "version" : 70002, "subver" : "/ElementsAlpha:0.10.2/", "inbound" : false, "startingheight" : 128650, "banscore" : 0, "synced_headers" : 128650, "synced_blocks" : 128650, "inflight" : [ ], "whitelisted" : false }, { "id" : 2, "addr" : "104.236.132.224:4242", "addrlocal" : "170.252.244.1:57671", "services" : "0000000000000001", "lastsend" : 1455547063, "lastrecv" : 1455547064, "bytessent" : 1925, "bytesrecv" : 2711, "conntime" : 1455547063, "pingtime" : 0.45263300, "version" : 70002, "subver" : "/ElementsAlpha:0.10.2/", "inbound" : false, "startingheight" : 128650, "banscore" : 0, "synced_headers" : 128650, "synced_blocks" : 128650, "inflight" : [ ], "whitelisted" : false } ]

It actually looks like an error is occurring inside alphad itself during the sendrawtransaction call.

I'm also getting the same error when trying to claim-on-sidechain. I'm trying to build a different sidechain and create the documentation for other users as the current instructions are not clear. I've changed the port numbers in constants.py and chainparamsbase.cpp (essentially just replacing 4241 with 4242). I've rebuilt both alphad and bitcoind after editing cpp files. If I run getpeerinfo I also return the same result with my local ip in addrlocal. It fails at the txid = sidechain.sendrawtransaction(res_tx) line, but I think it is because there's a communication error with the ports.

Ok we've found the issue:
https://github.com/ElementsProject/elements/blob/alpha/src/script/interpreter.cpp#L1469

Same issue but in alpha instead post-libsecp update. Fix incoming.

Try this: #84

@instagibbs
It works now with the claim-on-sidechain call.
I will try with other calls and let you know.
Huge thanks!
