Bitcoin WhitePaper Day

Bitcoin – A Peer-to-Peer
Electronic Cash System

It’s bitcoin White Paper Day.

The mailing list was hosted by Metzdow and run by a group of cypherpunks who shared ideas on creating a kind of digital currency and payment system. Satoshi shared the whitepaper in a message that read, “Bitcoin P2P e-cash paper,” which outlined the main properties of the system.

I’ve been working on a new electronic cash system that’s fully
peer-to-peer, with no trusted third party.

The paper is available at:
http://www.bitcoin.org/bitcoin.pdf

The main properties:
Double-spending is prevented with a peer-to-peer network.
No mint or other trusted parties.
Participants can be anonymous.
New coins are made from Hashcash style proof-of-work.
The proof-of-work for new coin generation also powers the
network to prevent double-spending.

Bitcoin: A Peer-to-Peer Electronic Cash System

Abstract. A purely peer-to-peer version of electronic cash would
allow online payments to be sent directly from one party to another
without the burdens of going through a financial institution.
Digital signatures provide part of the solution, but the main
benefits are lost if a trusted party is still required to prevent
double-spending. We propose a solution to the double-spending
problem using a peer-to-peer network. The network timestamps
transactions by hashing them into an ongoing chain of hash-based
proof-of-work, forming a record that cannot be changed without
redoing the proof-of-work. The longest chain not only serves as
proof of the sequence of events witnessed, but proof that it came
from the largest pool of CPU power. As long as honest nodes control
the most CPU power on the network, they can generate the longest
chain and outpace any attackers. The network itself requires
minimal structure. Messages are broadcasted on a best effort basis,
and nodes can leave and rejoin the network at will, accepting the
longest proof-of-work chain as proof of what happened while they
were gone.

The pseudonymous Bitcoin creator disclosed that they had been working on a new electronic cash system that uses a Proof-of-Work (PoW) consensus algorithm that required no trusted third party. Although the document met mixed reactions, it was the beginning of what is known today as blockchain technology.

A couple of months after the release, the Bitcoin network was launched, with the first block mined on January 3, 2009. About eight days later, Hal Finney received the first transaction of 10 BTC from Nakamoto, after which he posted a legendary tweet that read:

In the 14 years since that day, bitcoin’s value rose from zero to a peak of $68,990 last November and was hovering above $20,000 on Monday, according to CoinDesk data. The cryptocurrency currently has a market capitalization of over $390 billion. It also inspired the creation of more than 20,000 different cryptocurrencies currently in circulation, while bitcoin remains the largest by market cap.

Over the years, several people have been rumored to be Nakamoto, including early bitcoin contributor Hal Finney, cryptographer Nick Szabo, physicist Dorian Nakamoto and even Tesla’s chief executive Elon Musk, who all denied the claims.

Satoshi’s identity is still a mystery, but Finney was well-known for his contribution to the creation of Bitcoin. He worked hand-in-hand with Nakamoto to find and fix bugs in Bitcoin’s underlying infrastructure. Before his death in 2014, Finney shared a detailed story about his journey with Bitcoin

About a year after the launch of Bitcoin, the cryptocurrency went on to record its first real-world commercial use case when a Florida man spent 10,000 BTC to purchase two large Papa John’s pizzas on May 22, 2010.

Although the coins were worth $41 at prices back then, at today’s price, the transaction is worth more than $200 million. To commemorate the event, the Bitcoin community celebrates Bitcoin Pizza Day every year on May 22.

Bitcoin’s Store of Value

To any intelligent observer, it has been apparent that bitcoin’s primary use has emerged to be store of value/investment.

Yes, bitcoin’s decentralized/permissionless solution to creating an immutable cryptographically secured database brings a vast array of different potential revolutionary applications not seen since the advent of the internet but again, the primary use has emerged to be store of value/investment.

bitcoin has been so good at this store of value thing that it has become detrimentally  successful – enter the (well-funded) hacks and puppets…attacks from the outside and from within – some of which via spread of (FUD) tangent ideas with coders, media, investors, and within bitcoin community to maybe start an idea of even ‘slight’ change.

First, please realize no other tool in modern-day finance has been so successful at being an effective savings mechanism which unlike traditional ‘savings accounts’ this bitcoin actually keeps up in value for you to be able to afford higher cost of rent, education, healthcare, vacations, etc. (due to its beautiful combination of scarcity, a ceiling of 21mill coins, immutable, permissionless->not controlled/influenced, secure, and being established/developed).

This effective savings tool of bitcoin is made accessible to the 99% of us and cuts to the core of exposing the flaw of the central bank fiat system with its funny-money creation out of thin air paper/credit-currencies benefiting the privileged institutions and then last to benefit would be the rest of us.

It can also expose flaws of fraudulent funneling of extra paper-currencies created by central banks…now think, even those privy to any fraudulent funneling of funny-money will see what’s going on and understand something like bitcoin as an alternative being effectively immune to these games that even these bad-actors themselves would buy bitcoin! Bitcoin changes the paradigm of central-bank funny-money (Bitcoin is the anti-funny-money warrior: open & mechanism)….and it has taken off….and will catch the attention of the central banks who by definition, have nearly unlimited systemic resources and influence (think governments, telecoms ISP providers, hardware/chip manufacturers, software developers, search engines, exchange conartists).

Even if a hard-fork doesn’t happen anytime in the next couple of years, it’s the threat that an attack on this pure beautiful store of value system to something even slightly different that can actually gain a noticeable percentage raises the question…is it possible that someday that the groups influencing bitcoin (those controlling mining or those involved with coding development, or the rest buy/transacting in bitcoin) would (either out of ignorance/misunderstanding or out of vested-interest to undermine bitcoin) start demanding (even slight) changes that may contradict the store-of-value that bitcoin is???

That is the big question that if the answer starts looking like yes…then value would plummet as bitcoin no longer be seen as a store of value but would eventually turn into another app coin (i.e. Ethereum) that can do many amazing things but not the one store-value amazing thing that it has done these past few years. the price would be zero-bound (compared to what we’ve been accustomed to with bitcoin today).

If the answer to that question is no (that you reading this, this community, software coders, mining operators, investors, everyday folk, work to stay educated on the above and act to keep the integrity of this bitcoin system)…then even a $50 billion market cap would still be seen as trivial in the financial assets arena where one bitcoin can easily go above $5,000 USD. But really, as the years pack on and integrity remains intact, the price would be infinity-bound. 

Seven common mistakes crypto investors and traders make

Cryptocurrency markets are volatile enough without making simple, easily avoidable mistakes.

Investing in cryptocurrencies and digital assets is now easier than ever before. Online brokers, centralized exchanges and even decentralized exchanges give investors the flexibility to buy and sell tokens without going through a traditional financial institution and the hefty fees and commissions that come along with them.

Cryptocurrencies were designed to operate in a decentralized manner. This means that while they’re an innovative avenue for global peer-to-peer value transfers, there are no trusted authorities involved that can guarantee the security of your assets. Your losses are your responsibility once you take your digital assets into custody.

Here we’ll explore some of the more common mistakes that cryptocurrency investors and traders make and how you can protect yourself from unnecessary losses.

Losing your keys

Cryptocurrencies are built on blockchain technology, a form of distributed ledger technology that offers high levels of security for digital assets without the need for a centralized custodian. However, this puts the onus of protection on asset holders, and storing the cryptographic keys to your digital asset wallet safely is an integral part of this.

On the blockchain, digital transactions are created and signed using private keys, which act as a unique identifier to prevent unauthorized access to your cryptocurrency wallet. Unlike a password or a PIN, you cannot reset or recover your keys if you lose them. This makes it extremely important to keep your keys safe and secure, as losing them would mean losing access to all digital assets stored in that wallet.

Lost keys are among the most common mistakes that crypto investors make. According to a report from Chainalysis, of the 18.5 million Bitcoin (BTC) mined so far, over 20% has been lost to forgotten or misplaced keys.

Storing coins in online wallets

Centralized cryptocurrency exchanges are probably the easiest way for investors to get their hands on some cryptocurrencies. However, these exchanges do not give you access to the wallets holding the tokens, instead offering you a service similar to banks. While the user technically owns the coins stored on the platform, they are still held by the exchange, leaving them vulnerable to attacks on the platform and putting them at risk.

There have been many documented attacks on high-profile cryptocurrency exchanges that have led to millions of dollars worth of cryptocurrency stolen from these platforms. The most secure option to protect your assets against such risk is to store your cryptocurrencies offline, withdrawing assets to either a software or hardware wallet after purchase.

Not keeping a hard copy of your seed phrase

To generate a private key for your crypto wallet, you will be prompted to write down a seed phrase consisting of up to 24 randomly generated words in a specific order. If you ever lose access to your wallet, this seed phrase can be used to generate your private keys and access your cryptocurrencies.

Keeping a hard copy record, such as a printed document or a piece of paper with the seed phrase written on it, can help prevent needless losses from damaged hardware wallets, faulty digital storage systems, and more. Just like losing your private keys, traders have lost many a coin to crashed computers and corrupted hard drives.

Fat-finger error

A fat-finger error is when an investor accidentally enters a trade order that isn’t what they intended. One misplaced zero can lead to significant losses, and mistyping even a single decimal place can have considerable ramifications.

One instance of this fat-finger error was when the DeversiFi platform erroneously paid out a $24-million fee. Another unforgettable tale was when a highly sought-after Bored Ape nonfungible token was accidentally sold for $3,000 instead of $300,000.

Sending to the wrong address

Investors should take extreme care while sending digital assets to another person or wallet, as there is no way to retrieve them if they are sent to the wrong address. This mistake often happens when the sender isn’t paying attention while entering the wallet address. Transactions on the blockchain are irreversible, and unlike a bank, there are no customer support lines to help with the situation.

This kind of error can be fatal to an investment portfolio. Still, in a positive turn of events, Tether, the firm behind the world’s most popular stablecoin, recovered and returned $1 million worth of Tether (USDT) to a group of crypto traders who sent the funds to the wrong decentralized finance platform in 2020. However, this story is a drop in the ocean of examples where things don’t work out so well. Hodlers should be careful while dealing with digital asset transactions and take time to enter the details. Once you make a mistake, there’s no going back.

Over diversification

Diversification is crucial to building a resilient cryptocurrency portfolio, especially with the high volatility levels in the space. However, with the sheer number of options out there and the predominant thirst for outsized gains, cryptocurrency investors often end up over-diversifying their portfolios, which can have immense consequences.

Over-diversification can lead to an investor holding a large number of heavily underperforming assets, leading to significant losses. It’s vital to only diversify into cryptocurrencies where the fundamental value is clear and to have a strong understanding of the different types of assets and how they will likely perform in various market conditions.

Not setting up a stop-loss arrangement

A stop-loss is an order type that enables investors to sell a security only when the market reaches a specific price. Investors use this to prevent losing more money than they are willing to, ensuring they at least make back their initial investment.

In several cases, investors have experienced huge losses because of incorrectly setting up their stop losses before asset prices dropped. However, it’s also important to remember that stop-loss orders aren’t perfect and can sometimes fail to trigger a sale in the event of a large, sudden crash.

That being said, the importance of setting up stop losses to protect investments cannot be understated and can significantly help mitigate losses during a market downturn.

Crypto investing and trading is a risky business with no guarantees of success. Like any other form of trading, patience, caution and understanding can go a long way. Blockchain places the responsibility on the investor, so it’s crucial to take the time to figure out the various aspects of the market and learn from past mistakes before putting your money at risk.

Controlled Supply

Bitcoin

“A fixed money supply, or a supply altered only in accord with objective and calculable criteria, is a necessary condition to a meaningful just price of money.”

Fr. Bernard W. Dempsey, S.J. (1903-1960)

In a centralized economy, currency is issued by a central bank at a rate that is supposed to match the growth of the amount of goods that are exchanged so that these goods can be traded with stable prices. The monetary base is controlled by a central bank. In the United States, the Fed increases the monetary base by issuing currency, increasing the amount banks have on reserve or by a process called Quantitative Easing.

In a fully decentralized monetary system, there is no central authority that regulates the monetary base. Instead, currency is created by the nodes of a peer-to-peer network.

The Bitcoin generation algorithm defines, in advance, how currency will be created and at what rate. Any currency that is generated by a malicious user that does not follow the rules will be rejected by the network and thus is worthless.

Currency with Finite Supply

Block reward halving
Controlled supply

Bitcoins are created each time a user discovers a new block. The rate of block creation is adjusted every 2016 blocks to aim for a constant two week adjustment period (equivalent to 6 per hour.)

The number of bitcoins generated per block is set to decrease geometrically, with a 50% reduction every 210,000 blocks, or approximately four years. The result is that the number of bitcoins in existence will not exceed slightly less than 21 million.

Speculated justifications for the unintuitive value “21 million” are that it matches a 4-year reward halving schedule; or the ultimate total number of Satoshis that will be mined is close to the maximum capacity of a 64-bit floating point number. Satoshi has never really justified or explained many of these constants.

Cumulated bitcoin supply

This decreasing-supply algorithm was chosen because it approximates the rate at which commodities like gold are mined. Users who use their computers to perform calculations to try and discover a block are thus called Miners.

First Time/Small Miner

First time/Small miner reference
for getting started.

If you want to start mining here is what you need… and what you need to know.

This is written for home miners/small farms, but can be used as a guideline for most operations. Use this as a reference for what you need to research, or what questions you need to ask before jumping in.

What you need to mine can be broken down into the following categories:

  • Hardware
  • Electricity
  • Location
  • Internet connection
  • Information

Mining BITCOIN is done exclusively with dedicated BITCOIN mining hardware based on ASICs: https://en.wikipedia.org/wiki/Application-specific_integrated_circuit .

You CAN NOT meaningfully mine bitcoin today with CPU, GPU or even FPGAs. Bitcoin difficulty adapts to match the amount of mining done on the network and has reached levels trillions of times too high to mine meaningfully with PCs, laptops, tablets, phones, webpages, javascript, GPUs, and even generalised SHA hardware.

Even if you combined all the computers in the world, including all known supercomputer, you would not even approach 0.1% of the bitcoin hashrate today.

There isn’t any point attempting to mine bitcoin with CPU or GPU even in the interests of learning as it shares almost nothing with how bitcoin is mined with ASICs and will not teach you anything.

Hardware

Asic Miner:

Here is a list of the companies currently manufacturing Miners for public purchase.

Each one has their Pro’s and Con’s it is up to you to do your research and decide what is best for you.

A few points to consider while researching are :

  • efficiency
  • reliability
  • warranty period/policy
  • power draw

Each company has a different way of handling warranty repairs, depending on your situation and the policy repairs can become cost prohibitive. I will touch more on efficiency and power draw in the electricity section.

• Current list of competitive hardware

Power supply: You will need to purchase a power supply to run your miners. You will find ATX and Server grade PSU’s, the latter being preferred for mining BTC. 

When it comes to selecting a PSU purchase something with a capacity 25% higher than your miner is rated to draw. This will have you operating within the 80% rule.(explained further in the electricity section)

EX. Miner draws 1000 PSU should be able to provide 1250W.

** Many current generation miners are now being manufactured with Integrated PSU. Again do your research to see if your unit comes with or without. Generally you will still need to source a power cable.**

Auxilliaries – Avalon miners require an external controller, 1 per 20 miners. You may have to run additional fans for intake and exhaust depending on your location.

PSU’s can be purchased large enough to run 2 Miners; or the opposite 1 Miner fed by 2 PSU’s. Ensure the PSU you have selected will have the correct amount of PCI-E connectors required to operate your miner(s)

You can also find a large supply of used miners and PSU’s. Again it’s up to you to do your research as these often are a no return transaction.

Electricity

Follow all local codes and regulations

This is the number 1 factor in whether mining is right for you. As discussed with Miners being a 24/7 machine drawing power those costs will make it cost prohibitive for some people to mine. You need to be aware of what your costs/kWh are and run the numbers.

This will be done in a profitability calculator. This is just an example of 1 there are many out there.

( Miner usage in kW ) * ( Hours run per day ) 24 * ( Cost/kWh ) = Cost per Day to Operate

( Ideally less than the FIAT value of BTC mined )

The second part to the electrical requirements of mining is the available service; written for North America.

You will need to figure out the amperage you can spare, what circuits and receptacles you have in place, are you setting up on 220V or 110V. You will need to make sure that you have the right cord end for your PSU to match the receptacle, picking the wrong one can cost you a few days of mining if it has to be shipped.

If you can try and set up on a 220V circuit for 2 reasons :

– You will pull half the amps, and it is more efficient.

– Doing so requires 2 breaker spaces in your panel. Breaker sizing will depend on how many miners you plan to run. Here is the formula for calculating amps.

Watts / Voltage = Amps

Here is where you will bring the 80% rule back into play by sizing the continuous miner load to 80% of the breaker rating. 12 Amps on a 15 Amp breaker, 16 Amps max on a 20 Amp breaker, 24 Amps on a 30 amp breaker.

If/when you increase the amount of miners you are running you may want to look into PDU’s, as opposed to more receptacles. 

Location

This is something that is often overlooked to the headache and frustration of many would be miners. These machines are loud and hot .
You essentially have an electric heater that also uses an industrial fan to keep it from melting itself. This space will need to have the electrical requirements as discussed previously.

So make sure you have a space that is well ventilated with a plan to exhaust heat, and bring in fresh dust free air. I say this as using AC to cool the room will eat into your profits and may even make mining unprofitable.

The noise issue is a consideration you can sort out depending on whats available. (garage, basement, remote building)

Both of these issues can be handled with hosting, which is further explained in the information section.

Internet connection

Some miner setups have the option to use wifi. It is advisable to use a wired connection where available. This will provide a more stable connection and ensure you are submitting the expected amount of shares which is directly related to your payouts.

Please note that mining uses a negligible amount of bandwidth, and will not affect your other internet usage.

Information

You can use this information in this post as a good baseline to get you going. In addition to this you will want to research network difficulty; this readjusts every 2016 blocks to maintain a 10 minute block time on average. While this can go down it generally increases.

Solo or Pool?

You can solo mine but this is essentially a lottery even as a large scale miner. Should you chose this you can check this out as a starting point.

solo.ckpool.org 1% fee solo mining USA/DE 250 blocks solved!

Odds are most of you will join a pool. I will only say that it is in your best interest to mine at a pool that pays transaction fees (miner rewards). Then you will want to consider the fees associated with the pool.

When it comes to these pools you want them to be large enough that they are getting at least 1 block every Difficulty adjustment period. Larger pools will offer smaller rewards paid out more frequently, and vice versa.
