Maybe start them off nostr:npub1xkere5pd94672h8w8r77uf4ustcazhfujkqgqzcykrdzakm4zl4qeud0en and let River hold it until he learns how to self custody. Also Bitkey has a noob proof solution nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m . Also nostr:npub1cn4t4cd78nm900qc2hhqte5aa8c9njm6qkfzw95tszufwcwtcnsq7g3vle Strike can onboard and educate your friends. Keep going!

No kyc only

Love it and I understand Passport is user friendly; still not ideal for these buddies I mentioned lol

One of the friends that I got onto Bitcoin lost his phone and he never saved his seed phrase. It's just gone now.

Yesterday another friend got a new phone and was angry with me and he didn't have access to his wallet. Today he messaged me saying that he had found his backup. I just helped him restore the wallet.

I hope he learned his lesson.

Long story short, I don't think I'm never going to onboard anyone onto Bitcoin again. People just tend to lose their shit; and don't say that it's a contribution to the scarcity.

Feeling generous? Pay invoice please 🤠

Implementing a decentralized version of Samourai Wallet’s Whirlpool coin join protocol would require redesigning its existing coordinator-based architecture to remove reliance on a central server. Here’s a high-level approach:

---

1. Understanding Whirlpool's Current Design

Whirlpool currently relies on a coordinator to facilitate the coin join process.

Clients register inputs, the coordinator builds the transaction, and participants sign it.

The coordinator doesn’t take custody of funds but still knows the transaction structure before broadcasting.

2. Key Challenges for Decentralization

Removing the coordinator without reducing efficiency.

Ensuring Sybil resistance to prevent DoS or manipulation.

Maintaining privacy while coordinating transactions.

Minimizing reliance on a single blockchain explorer or external services.

---

3. Decentralized Whirlpool: Potential Design Approaches

To decentralize Whirlpool, we could leverage one or a combination of the following:

A. Peer-to-Peer (P2P) Coordination Using Tor/I2P

Use a DHT (Distributed Hash Table) for peer discovery.

Clients initiate coin joins directly in a P2P fashion.

Nodes use Tor or I2P for anonymity.

B. Federated or Multiparty Coordination

Instead of a single server, use multiple semi-trusted facilitators.

Shamir’s Secret Sharing could be used to prevent any single entity from knowing the full transaction structure.

A threshold cryptographic scheme could allow transactions to be constructed collectively.

C. Bitcoin Script & Covenant Approaches

Use vault-like smart contracts (e.g., OP_CTV, OP_CHECKSIGFROMSTACK) to enforce coin join conditions.

Create "CoinJoin Pools" where users deposit funds and can only withdraw through pre-agreed anonymity conditions.

D. Lightning Network for Pre-Mixing

Before on-chain settlement, users could mix UTXOs off-chain via the Lightning Network.

This avoids large on-chain transaction fees and improves speed.

---

4. Implementation Steps

1. Peer Discovery Layer

Use a decentralized network (DHT, Nostr relays, or LN-based signaling).

Implement a reputation system to mitigate Sybil attacks.

2. Decentralized Input Coordination

Use a Zero-Knowledge proof system (e.g., zkSNARKs) to verify valid inputs without revealing them.

Alternatively, Ring Signatures or Threshold Signatures could be used.

3. Transaction Construction Without a Coordinator

Each participant signs their input separately.

Use secure multiparty computation (MPC) to build the final transaction.

4. Broadcast & Finalization

The final transaction is either broadcast by multiple peers simultaneously or via a privacy-preserving relay (e.g., FIBRE, Tor).

5. Potential Risks & Mitigation

6. Conclusion

A fully decentralized Whirlpool would likely rely on P2P coordination, zero-knowledge proofs, and multiparty computation to remove the need for a trusted coordinator while preserving privacy and efficiency. It would be a complex but highly valuable upgrade to Bitcoin's privacy ecosystem.

I see you now, it also used your lightning handle as walking smoke
