Silent payments are a type of payment that can be made to a unique on-chain address for every payment, even though the receiver provided the spender with a reusable (off-chain) address. This mechanism helps improve privacy in Bitcoin transactions.
The mechanics of silent payments work as follows:
- Address Reuse Avoidance: One of the most basic keys to improving your privacy on Bitcoin has long been avoiding the re-use of addresses for multiple payments. Address reuse leads to a significant erosion of privacy because it creates a public record of transactions on the blockchain, which can potentially be traced back to the user.
- Unique On-Chain Address Generation: When the sender enters the Silent Payment address into their wallet, their wallet will combine three keys to create a unique, one-time address that only the intended recipient can spend from. Each time a silent payment is made, it automatically generates a new (regular) bitcoin address for that specific transaction.
- Privacy and Security: Silent payments remove the need for a notification transaction entirely by leveraging the outputs in a transaction to signal to the recipient when funds are intended for them. This process protects both the sender's and the recipient's privacy. It also reduces security risks associated with exposing more information about your private key with each transaction.
- Blending In: The resulting transactions from silent payments blend in with other Bitcoin transactions and can't be distinguished. This makes it harder for an outside observer to link multiple payments to the same sender.
In summary, silent payments provide a way to make Bitcoin transactions more privately by avoiding address reuse, generating unique on-chain addresses for each transaction, and blending in with other transactions. However, it's important to note that while silent payments enhance privacy, they do not provide complete anonymity. The level of privacy afforded to users largely depends on how they use the Bitcoin protocol.
Dandelion++ is a transaction routing mechanism proposed to enhance privacy in Bitcoin transactions. It was developed by Brad Denby, Andrew Miller, Giulia Fanti, Surya Bakshi, Shaileshh Bojja Venkatakrishnan, and Pramod Viswanath.
The protocol was designed to defend against deanonymization attacks during transaction propagation. In Bitcoin's transaction spreading protocol, a node transmits a transaction to its peers with independent, exponential delays, which allows network adversaries to link transactions to IP addresses. Dandelion++ mitigates this class of attacks by sending transactions over a randomly selected path before diffusion. This process consists of two phases: the "stem phase" and the "fluff phase". During the stem phase, transactions travel along a randomly selected path, and during the fluff phase, they are diffused.
Despite its potential benefits, Dandelion++ has not been implemented in Bitcoin. The Bitcoin Improvement Proposal (BIP) 156 for #Dandelion++ was rejected. One of the reasons for the resistance to implement Dandelion++ in Bitcoin could be the complexity of the implementation and potential issues related to network topology.
However, Dandelion++ has been adopted by other cryptocurrencies. For instance, it was applied to #Monero by developer Lee Clagett, with testing and review by developer moneromooo. In Grin, Dandelion++ also provides an opportunity to aggregate transactions before they are broadcast to the entire network.

A lot of San Clemente punani smashed when I was stationed at Camp Lejeune. Gorgeous area.
He’s not wrong though

To create a raw transaction using the Bitcoin command-line interface (bitcoin-cli), you can follow these steps:
1. **Create the Raw Transaction:**
- The `createrawtransaction` command allows you to create a transaction spending specific inputs and creating new outputs. The inputs are specified as a JSON array, and the outputs can be either addresses or data.
- Here's the basic syntax:
```
bitcoin-cli createrawtransaction "[{\"txid\":\"myid\",\"vout\":0}]" "[{\"address\":0.01}]"
```
Replace `"myid"` with the actual transaction ID (txid) and `0` with the corresponding output index (vout). The output amount is specified as `0.01 BTC` in this example.
2. **Sign the Raw Transaction:**
- After creating the raw transaction, you need to sign it using the `signrawtransactionwithkey` command. This step ensures that the transaction is valid and authorized.
- You'll need the private keys corresponding to the inputs used in the transaction.
3. **Broadcast the Signed Transaction:**
- Finally, use the `sendrawtransaction` command to broadcast the signed transaction to the Bitcoin network.
- The signed transaction will be propagated to other nodes and included in the blockchain.
Remember to replace the placeholders (`myid`, `0.01`, etc.) with actual values relevant to your use case. If you have additional inputs or outputs, adjust the command accordingly. 😊
