While witness data costs much less, a more efficient encoding in the witness data is still cheaper, so your point of using a more efficient encoding is still valid.

1. If you can create a way to store a private key without knowing it, such that it can be retrieved once by anyone who holds it, you have invented something very valuable.

2. The only difference is who loads the coin, assuming that it can be loaded.

15 sat/vb is generally too much, but it varies depending on what other transactions are paying and how many transactions are waiting. As you can see, sometimes the necessary fee can be quite high, but there are times when 1 sat/vb will get it into the next block.

Helpful tips:

• 1. Look up the current transaction fees before sending. Wallets can be unreliable, so I look at mempool.space or other similar sites to see what the fees look like.
• 2. Be patient. If you are paying for something, then you might want to pay a fee that will get the transaction into the next block. But, if you are just moving money around, you can save some money by paying a lower fee and waiting longer.
• 3. Use RBF. If the fee turns out to be too low, you can increase it with RBF.

I don't subscribe to the manipulated CPI conspiracy theory, but the asset inflation is a good point.

I suggest learning to code without any particular application in mind at first. Start out with a language that is easy to learn and widely used such as Python or Javascript.

There are many sites that teach coding. I don't have any recommendations, but try https://www.codecademy.com/.

While mastering the basics, you might try to write applications that can create and process SQL queries or interact with financial APIs.

I don't see how simply copying data to an SD card is going to affect its life significantly but I don't think running a node on an SD card will work very well because I/O is very slow and an SD card has a much lower life expectancy than an SSD.


I have Raspibolt running on a RPi 4 with 8 GB RAM and a 1 TB SSD. It works well. Memory usage is around 4GB so I think 8GB is preferable in order to avoid swapping. I normally interact with the RPi through SSH, so no keyboard and monitor are necessary.

Also, RPi kits are currently in short supply so you might have trouble buying one.

I think there is a problem with the fact that ultimately UTXOs must be addressed individually, so somewhere there must be a set of individual UTXOs. And while there is a potential optimization of the node software in classifying UTXOs according to the likelihood of being spent in the next few blocks, that would make the node software more efficient but it wouldn't affect the protocol.

Also, I suggest that you check out this thread that discusses adding UTXO commitments to the block chain: Ultimate blockchain compression w/ trust-free lite nodes

It's a lot more complicated than that.

Please explain to me why the doubling of the USD monetary base since 2020 has not caused a doubling in prices, and why there has been 10% inflation over the last year while the monetary base has dropped by 15%.

You might claim that inflation lags the money printing, but how long is that lag? How do you explain the low inflation rate for the 13 years between 2008 and 2021, even though the USD monetary base increased by 500%.

"Ordinals" is the enumeration scheme and "inscriptions" is an application of Ordinals, but I guess people may refer to inscriptions as ordinals because that is its main use.

I don't disagree with your assessment of inscriptions, but I wouldn't go as far as to call it an "attack". That's like saying that Bitcoin is an environmental problem because it uses too much electricity.

It may be crazy but it is not a lie.

Someone came up with an method of enumerating satoshis as well as a convention for maintaining the enumeration even while the satoshis are used in transactions. As a result, it is possible to give every satoshi an ID and to track it from transaction to transaction. Note that Ordinals is not the only way to do this, and it only works for those people using the Ordinals protocol.

Now, the lie that @pooya87 is describing (beyond the basic lie about NFTs indicating anything more than an association) is the fact that if you don't agree to and adhere to the Ordinals protocol, then it means nothing. And there is nothing preventing me from creating my own enumeration protocol that associates an inscription of my choice with a satoshi that I own.

My own opinion is that Ordinals is very clever and I applaud the creator, Casey Rodarmor. However, whether or not it becomes useful remains to be seen. I predict that future node software will allow pruning of inscription data as an option in order to reduce the size of the blockchain if inscriptions remain popular.

All Bitcoin transactions are recorded in the block chain. A miner is a company that gets paid to collect new transactions into a "block" and add the block to the block chain.

The ability to add each block to the block chain is determined by luck. It is a kind of lottery. Each miner computes a number that is based on its block (called a "hash") over and over until some miner somewhere computes a winning hash. When a winning hash is found, everybody adds the winning block to their copy of the block chain and then all of the miners start competing for the next block. Typically, when a miner has computed a winning hash, we say that they have "found" or "solved" a block.

Of course, a miner that compute hashes more quickly is more likely to find blocks, but computing a hash uses electricity and computing more hashes costs more money, so only the efficient miners are able to make a profit.

A "mining pool" is a group of miners that work together and act as a single miner. If one of the members of the pool finds a block, then all of the members share the block reward.

The payment to the miner is called the "block reward". It consists of fees paid by the transactions plus the "subsidy", which is currently 6.25 BTC. To get paid, the miner simply includes a special transaction in the block that pays them the correct amount. This transaction is called the "coinbase" transaction.

New bitcoins are created by the subsidy. The initial subsidy was 50 BTC, but it is halved every four years approximately until it reaches 0 around the year 2140. Of course, as the subsidy is reduced, the transaction fees will become an increasingly larger portion of the block reward. When the subsidy reaches 0, no more bitcoins will be created and there will be about 21 million bitcoins.

Using biometrics to generate a unique and invariable key is not a new idea, and it has already been discussed here many times. Such a capability has yet to be implemented.

Who knows? Someday, Bitcoin may become an integral part of some cybersecurity method, but for now Bitcoin just uses cryptography for its own security.


While it is convenient to think of a transaction as moving bitcoins from address A to address B, nothing is really moved in a transaction. Transactions are just changes in ownership. A typical transaction basically states that, "I have a private key that controls this amount of bitcoins at address A, and now whoever has a private key for address B controls them."


Most people would say impossible because that is a simple and practical answer, but the correct answer is inefficient or impractical. It is nearly impossible, but not strictly impossible to brute force a private key because there is an incredibly small chance that it will be found. It is inefficient and impractical because the expected cost of brute forcing a private key exceeds the value controlled by any private key by many orders of magnitude.

Some perspective:

If you are "averagely comfortable" in the U.S., you are in the top 5% in the world. That is, your standard of living is higher than 95% of the rest of the people in the world.

The IRS has made an odd change to its policy regarding the treatment of Bitcoin:


In short, it says, "We recognize that Bitcoin is legal tender in some countries, so it is a real currency and not a virtual currency, but we don't like that, so we are going to ignore the law."

There is a problem with only allowing nodes to join if they have 51% approval. A group with 51% control could kick out the other 49% and gain 100% control forever, and it would cost them nothing.

Bitcoin has a similar problem except that the 51% must be maintained in order to keep control, and also it is difficult (and dangerous) to reach 51% given that the largest miners are pools.

LeGaulois, adding the mixer to the list is your stamp of approval. Why would you add it to the list if you have evidence that it is a scam?

My main concern is that creating a mixer is an easy way to scam people. With all of these new recommendations, I wonder if any have really been vetted.

I think that a person who recommends a mixer should also provide some kind of guarantee, so that if the site turns out to be a scam, the person who recommended it must compensate the victims.


I certainly do not trust [banned mixer]. The mixer is recommended by someone whose only post on this site is that recommendation.

Do you really believe that The Onion is "a very reputable news source" and that the video is real, or are you just trolling?

Sorry. That video is satire. Read this: The Onion

The headline is misleading. He was not jailed for hiding bitcoins.
