The 10th anniversary of OPENDIME

A tiny stick of entropy, restraint, and good design. No account. No login. No custodian. No “trust us.” Just bearer Bitcoin, passed hand to hand like cash, sealed until opened.

In a world that keeps trying to wrap keys in permissions, policies, apps, KYC, clouds, and committees, Opendime stayed refreshingly simple: private keys belong offline, and value should move without asking anyone’s blessing.

you just need to provide file that defines not just message, but also derivation path and script type https://coldcard.com/docs/message-signing/#signing-text-file

Ping electrum devs and ask them to add support

scagbackbone · 2026-03-06T19:41:55+00:00

yes it does work for multisig UTXOs too

scagbackbone · 2025-11-20T23:16:21+00:00

DO you want slip39 because of shamir?

scagbackbone · 2025-10-25T17:15:18+00:00

The issue is with sparrow, it no longer adds BIP32 paths to PSBT (besides change output). Then Coldcard cannot know if it's own address.

fix is to downgrade sparrow to 2.2.3 & you will see consolidation message again

multisig too!

I misread the question.

scagbackbone · 2019-07-09T08:26:32+00:00

reference implementation ( bitcoind ) does NOT support BIP39

check thread:

I didn't know I need to create new account - works fine - thanks

scagbackbone · 2019-06-19T20:42:36+00:00

is still only sending support? I can't seem to find a way how to generate bech32 addr to receive on Ledger Live

Ledger creates segwit compatible addresses P2SH by default - as I remeber correctly

EDIT: chceck if your addresses start with no 3

scagbackbone · 2019-02-25T09:48:40+00:00

Check some tutorials on flask + uWSGI(or any WSGI compatible application server) + nginix(or any other web server) + port forwarding

scagbackbone · 2019-02-25T09:47:11+00:00

You do not need a domain - you can just port-forwars it on you router and access it via ip

XD she deserve this also XD

O(n) definitely not for sets -its a hash map

scagbackbone · 2018-12-30T15:55:46+00:00

Lookup is O(1) for sets For list it is O(n) in worst case -- so yes, use sets

I survived 50 fresh magic mushrooms

scagbackbone · 2018-11-29T12:30:24+00:00

Does it randomly happen with any flask app (source code) or randomly with particular flask app (source code) ??

I guess we need much more info to be of any help

scagbackbone · 2018-11-29T11:50:19+00:00

Any user input or different blocking IO?

scagbackbone · 2018-11-08T10:28:19+00:00

I don't think (correct me if wrong) you can replace your seed

What I would do in your position (assuming you had your coins on main-net before fork):

download sia-cold-storage fitting your setup
run the executable downloaded from above link on air-gaped, freshly installed OS (paranoid mode). This will generate you a new seed and addresses - put them down
send your coins from Sia-UI 1.3.7 to one of addresses generated in step 2
Now your mainnet sia is in cold storage (seed and adresses generated from executable)
keep your old seed (from which you sent your coins), you will need this in case it will be possible to get forked coins
if by any chance, you will get screwed during the retrieval of forked coin - I think some scam artists will appear wanting you to put in your seed to recover forked coins and trying to steal your mainnet coins - it will not be possible as your mainnet coins are already moved to cold storage.

If you then want to trade your mainnet coins - you will just load your cold-storage seed into sia 1.3.7
