Your Silence…

Silenceย is the absence of ambientย audibleย  sound, the emission of sounds of such lowย intensityย that they do not draw attention to themselves, or the state of having ceased to produce sounds; this latter sense can be extended to apply to the cessation or absence of any form ofย communication, whether throughย speechย or other medium.

Sometimes speakers fall silent when they hesitate in searching for a word, or interrupt themselves before correcting themselves.

Discourse analysisย shows that people use brief silences to mark the boundaries ofย prosodic units, inย turn-taking, or as reactive tokens, e.g., as a sign of displeasure, disagreement, embarrassment, desire to think, confusion, and the like.

Relatively prolonged intervals of silence can be used inย rituals; in some religious disciplines, people maintain silence for protracted periods, or even for the rest of their lives, as an ascetic means of spiritual transformation.

Joseph Jordaniaย has suggested that inย social animalsย (includingย humans), silence can be a sign of danger.

Many social animals produce seemingly haphazard sounds which are known asย contact calls. These are a mixture of various sounds, accompanying the group’s everyday business (for example, foraging,ย  feeding), and they are used to maintainย audioย contact with the members of the group.

Some social animal species communicate the signal of potential danger by stopping contact calls and freezing, without the use ofย alarm calls, through silence.

Charles Darwinย wrote about this in relation with wild horse and cattle.ย Jordania has further suggested that humanย hummingย  could have been a contact method that early humans used to avoid silence. According to his suggestion, humans find prolonged silence distressing (suggesting danger to them).

This may help explain why lone humans in relative sonic isolation feel a sense of comfort from humming, whistling, talking to themselves, or having the TV or radio on.

Best Pool Rules

Best Pool Rules

In my opinion, more or less in order:

1) ย Lowest fees

1a) ย Shares transaction fees

1b) ย Any pool that does NOT share transaction fees should be rejected from consideration (which, unfortunately, is most, if not all, Chinese based pools)

2) ย Reasonable variance – You need to get paid often enough to be happy. This is a tough one.

Variance is the close cousin to “Luck”.

The luckier a pool is, the more blocks it finds relative to its hashing speed, and the less variance it will have. ย But its not a real thing! ย “Luck” could change any microsecond.
ย “Luck” is just mathematical statistics – over a long enough time period, all pools will average out to 100% luck.

Luck Statistik for 14 Blocks

You need to understand Variance:

A big pool finds more blocks, but distributes the earnings out to more miners. ย 

A small pool is just the reverse: ย it finds fewer blocks, but pays those earnings to fewer people. Over the long run, Rule #1, well, rules.

3) ย Wind-up/Wind-down time – Most pools use some leveling algorithm.

4) ย User Interface – That doesn’t matter much if you have a few miners. ย If you have hundreds, the difference can be thousands of dollars a Year.

Notes:

A) In the long run #2 & #3 really don’t matter much. ย Both pools show your hashing rate in minutes, payouts just lag on Kano compared to Slushpool, but would continue longer if you changed in the future

B) Bigger is not better. ย Sure Antpool is #1 in size, in no small part to Bitmain using their own pool (no fees for them!). ย  Your profit will be determined mostly by rule #1 – lower fees mean more profit.

C) More, smaller, pools is healthier for the blockchain. ย If you can live with the variance, support the pool with the longest average payout you are happy with.

D) For pools with long ramp up times that are relatively small, like Kano, you MIGHT suffer due to difficulty changes while you ramp up.

For smaller pools, make sure you understand what happens to your efforts (based on their scoring system) when a difficulty change occurs.

The Laws are Unjust

As we’ve seen over the many years that this rag has been written (and beyond) companies who are able to fund whole teams dedicated to data security have been wholly ineffective at storing that data safely.

With the passage of this new law EU officials are actively putting citizens in harm’s way by irresponsibly trying to force bitcoin users to collect and store each other’s data. This is if you believe that is the actual intention behind this move.

In reality, this move likely serves as a pure intimidation tactic to coerce people to use trusted third parties when transacting with bitcoin.

A heavy handed shove into easily controlled vectors. If too many users are in control of their own private keys, run their own nodes, and are up to date on best privacy practices when transacting it is much harder to stop bitcoin.

And make no mistake, these people want to stop bitcoin at all costs.

They do not want you to be free.

They are quickly losing their grasp of control on the populace and they are moving as quickly as possible to clamp down in an attempt to retain control.

You are not meant to have privacy in their eyes. You are inherently a criminal in their eyes. These people think you are disgusting cattle who needs to be led at every turn.

It does not have to be this way. You do not have to succumb to the madness of these people. All it takes are a few decisions.

Speak up!

Act!

Disobey!

There is a silent majority out there who knows this type of attempted control is inherently wrong.

It is anti-human!

It is evil!

This silent majority needs to begin developing the courage to speak up.

Call out the abject insanity of allowing unelected institutions like the Financial Action Task Force write freedom restricting guidelines that get adopted by governments like the EU.

Learn how to run your own node, how to produce your own private/public key pairs, and how to destroy chain analysis heuristics with privacy best practices.

Make the tyrant’s job as hard as possible!

Disobey!

Stand up and defend freedom in the Digital Age by actively defying their unjust laws.

“If a law is unjust, a man is not only right to disobey it, he obligated to do so.”

It is your duty as an individual to disobey these incredibly invasive and tyrannical “laws”.

If you don’t disobey your progeny may not have the opportunity to. The time to counter punch is right now. Get on it.

Sapere Aude

Etymology

It is from the epithet of a parable, explaining that a fool waits for the stream to stop before crossing, while a wise man forgoes comfort and crosses anyway.

The original use seems to be in Epistle II  of  Horace‘s Epistularum liber primus:

“Dimidium facti qui coepit habet: sapere aude” (“He who has begun is half done: dare to know!”).

Phrase

sapere audฤ“

  1. “Have the courage to think for yourself“
  2. “Have courage to use your own reason“, in the context of committing to tasks that need to be embarked upon, however unpleasant or awkward.
  3. “Dare to be wise”, the motto of the Enlightenment.

Usage notes

Kant answers the question in the first sentence of the essay: “Enlightenment is man’s emergence from his self-incurred immaturity (Unmรผndigkeit).”

He argues that the immaturity is self-inflicted not from a lack of understanding, but from the lack of courage to use one’s reason, intellect, and wisdom without the guidance of another.

Kant argued that using one’s reason is considered dangerous by most men and all women.

He exclaims that the motto of the Enlightenment is “Sapere aude“! โ€“ Dare to be wise!

“Enlightenment is man’s release from his self-incurred tutelage.

Tutelage is man’s inability to make use of his understanding without direction from another.

Self-incurred is this tutelage when its cause lies not in lack of reason but in lack of resolution and courage to use it without direction from another.

Sapere Aude!

‘Have courage to use your own reason!’- that is the motto of enlightenment.”

Immanuel Kant

Convergence of blockchain with AI and IOT

IoT and AI are growing exponentially

Internet of Things – IoT

A future of transacting intelligent machines

โ€ข Individually, each of these technologies deserves all the attention they’re getting as enablers and disruptors

โ€ข But, taken together?

โ€ข Their transformative effect becomes multiplicative

โ€ข A future driven by machine connectivity, data exchange and commercial services:

  • IoT connects billions of machines and sensors generate unprecedented quantities of real-time data
  • AI enables the machines to act on data and trigger services
  • Blockchain functions are the transaction layer where data and service contracts are securely stored and payments for services are settled

How does blockchain support intelligent connected machines?

โ€ข Smart Contracts enable self-executing and self-enforcing contractual states

  • Custom financial instruments (tokens), records of ownership of an underlying physical asset (smart property), any
  • complex business logic that can be programmable
  • Can such applications be ideal for intelligent (AI) and connected (IoT) machines?
  • These machines are intelligent enough to negotiate contracts, but need a technology allowing them to securely sign and enforce them

โ€ข Digital currencies create new forms of money

  • Programmable and active
  • Will such money be ideal for intelligent (AI) and connected (IoT) machines?
  • These machines will need digital currency to pay for services assigned through the smart contracts

How will the three technologies work together?

IoT – Internet of Things

  • Sensors allow us to cost-effectively gather tremendous amounts of data.
  • Connectivity allows us to transmit/broadcast these data.
  • But, there is a missing element: intelligence to process these data.

AI – Artificial Intelligence

  • Intelligence at the very edges of the network (mini-brains).
  • Combine with IoT and you have the ability to recognize meaningful patterns buried in mountains of data in ways that would be impossible for most humans, or even non-AI algorithms, to do.
  • But, there is a missing element: a secure storage layer for data and a transaction layer for services

DLT (blockchain) – Distributed Ledger Technology

  • Decentralized governance, coupled with no single point of failure, disintermediation, unalterable and searchable records of events.
  • Digital currencies and tokenized custom financial instruments.
  • Combine with AI and IoT and you have a new world of autonomous systems interacting with each other, procuring services from each other and settling transactions.

The technology stack of the future

Technology Stack of the Future

Toward a world of machine commerce

A world of Machine Commerce

M2M will need SSI (self-sovereign identities) – for objects!

Human Identities types

Object identities can be SSI by default

  • Multi-source, multi-verifier
  • Digitally signed, verifiable credentials that can prove issuer, holder and status
  • Secure peer-to-peer connections (permanent or session-based)
  • Exchange full credentials, partial credentials or ZKPs derived from credentials

Next milestone: Decentralized Organizations (DOs)

DOs are good at:

  • Coordinating resources that do not know/trust each other (including hybrid
  • H/M)
  • Governing in a geography-agnostic, censorship-resistant manner
  • Enabling short-term or informal organizational structures  (networks/communities)
  • Tracking and rewarding contribution

Challenges

  • Jurisdictional issues
  • Legislating new types of work for humans and work rules for machines
  • Governance modalities, including external supervision

Challenges

New/upgraded system architectures

โ€ข From legacy to blockchain/AI/IoT-native systems
โ€ข Integration, interoperability, backward compatibility
โ€ข ROI obvious ex post, difficult ex ante โ€“ Bootstrapping

Advanced analytics capabilities

โ€ข As devices at the edge become smarter, the smart contracts enabled by blockchain platforms will require more advanced data analytics capabilities and gateways to the physical world.

New Business Models

  • Disruptive innovation will dominate โ€“ but not without boom-and-bust cycles and big failures along the way.
  • Winners will NOT be the ones focusing on efficiency gains, but on disruptive models.

Key takeaways

โ€ข IoT, AI and DLT (blockchain) are foundational and exponentially growing technologies

  • When combined, they will create a new internet of connected, intelligent and commercially transacting machines
  • An era machine-to-machine (M2M) and human-to-machine (H2M) commerce is likely to emerge, with profound consequences on social and economic dynamics
  • New forms of corporations or organizational formats (code-only, autonomous) will emerge

โ€ข There are numerous challenges that must be overcome

  • IoT has outpaced the human internet, but is still a largely passive, insecure and privacy-vulnerable network
  • AI has made huge leaps, but still requires immense computational resources and is largely incompatible with edge computing
  • DLT is a new technology, largely untested at scale; both smart contracts and digital assets lack the regulatory clarity required for mass adoption

Au – ๐Ÿ’ฒ – โ‚ฟ

Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally.

It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form.

Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions.

Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element  silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite.

Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

A relatively rare element, gold is a precious metal that has been used for coinage,  jewelry, and other arts throughout recorded history.

In the past, a gold standard was often implemented as a monetary policy.

Still, gold coins ceased to be minted as a circulating currency in the 1930s, and the world gold standard was abandoned for a fiat currency system after 1971.

As of 2017, the world’s largest gold producer by far was China, with 440 tonnes per year.

A total of around 201,296 tonnes of gold exists above ground, as of 2020. This is equal to a cube with each side measuring roughly 21.7 meters (71 ft).

Gold’s high malleability, ductility, resistance to corrosion and most other chemical reactions, and conductivity of electricity have led to its continued use in corrosion-resistant electrical connectors in all types of computerized devices (its chief industrial use).

The world consumption of new gold produced is about 50% in jewelry, 40% in investments and 10% in industry.

Gold is also used in infrared shielding,  colored-glass production, gold leafing, and tooth restoration. Certain gold salts are still used as anti-inflammatories in medicine.

F I A T

Fiat money (from Latin: fiat, “let it be done”) is a type of money that is not backed by any commodity such as gold or silver, and typically declared by a decree from the government to be legal tender.

Throughout history, fiat money was sometimes issued by local banks and other institutions. In modern times, fiat money is generally established by government regulation.

Yuan dynasty banknotes are a
medieval form of fiat money

Fiat money does not have intrinsic value  and does not have use value. It has value only because the people who use it as a medium of exchange agree on its value. They trust that it will be accepted by merchants and other people.

Fiat money is an alternative to commodity money, which is a currency that has intrinsic value because it contains a precious metal such as gold or silver which is embedded in the coin.

Fiat also differs from representative money, which is money that has intrinsic value because it is backed by and can be converted into a precious metal or another commodity.

Fiat money can look similar to representative money (such as paper bills), but the former has no backing, while the latter represents a claim on a commodity (which can be redeemed to a greater or lesser extent).

Government-issued fiat money  banknotes  were used first during the 11th century in China.

Fiat money started to predominate during the 20th century.

Since President Richard Nixon‘s decision to default on the US dollar convertibility to gold in 1971, a system of national fiat currencies has been used globally.

Fiat money can be:

  • Any money that is not backed by a commodity.
  • Money declared by a person, institution or government to be legal tender, meaning that it must be accepted in payment of a debt in specific circumstances.
  • State-issued money which is neither convertible through a central bank to anything else nor fixed in value in terms of any objective standard.
  • Money used because of government decree.
  • An otherwise non-valuable object that serves as a medium of exchange (also known as fiduciary money.)

The term fiat derives from the Latin word  fiat, meaning “let it be done” used in the sense of an order, decree or resolution.

Bitcoin – Digital Gold

The most common, and best, ways to think about bitcoin is as “digital gold”.

Like gold, bitcoin doesn’t rely on a central issuer, can’t have its supply manipulated by any authority, and has fundamental properties long considered important for a monetary good and store of value.

Unlike gold, bitcoin is extremely easy and cheap to “transport”, and trivial to verify its authenticity.

Bitcoin is also “programmable”. This means custody of bitcoin can be extremely flexible. It can be split amongst a set of people (“key holders”), backed up and encrypted, or even frozen-in-place until a certain date in the future. This is all done without a central authority managing the process.

You can walk across a national border with bitcoin “stored” in your head by memorizing a key.

The similarities to gold, plus the unique features possible because bitcoin is purely digital, give it the “digital gold” moniker.

Sharing fundamental properties with gold means it shares use-cases with gold, such as hedging inflation and political uncertainty.

But being digital, bitcoin adds capabilities that are especially relevant in our modern electronic times.

The world does indeed need a digital version of gold.

ASICs vs. SuperComputers

ASICs vs Supercomputers

Assigning the most powerful supercomputer to mine bitcoin would be comparable to hiring a grandmaster chess player to move a pile of bricks by hand.

The job would get done eventually but the chess player is much better at thinking and playing chess than exerting energy to repetitively move bricks.ย 

Likewise, combining the computing power of the most powerful supercomputers in the world and using them to mine bitcoin would essentially be pointless when compared to the ASIC machines used today.

ASICs are designed to do one thing as quickly and efficiently as possible, whereas a supercomputer is designed to do complicated tasks or math problems.

Since Bitcoin mining is a lottery based on random trial and error rather than complex math, specialization (ASICs) beats general excellence (supercomputers) everytime.

Welcome…

To the rabbit hole…

Why this crazyness with rabbits ?!? And their holes, you would ask ?!? Why is the rabbit hole so deep ?ยฟ

And what does the rabbit hole has to do with that BitCorn thingย  I keep hearing about all over the place ?ยฟ

I like to start from the begining, as I think so I am ๐Ÿ˜‹๐Ÿ˜‚

Rabbit Hole is a play written by David Lindsay-Abaire. It was the recipient of the 2007 Pulitzer Prize for Drama. The play premiered on Broadway in 2006, and it has also been produced by regional theatres in cities such as Los Angeles, Philadelphia and Pittsburgh. The play had its Spanish language premiere in San Juan, Puerto Rico in Autumn of 2010.

The play deals with the ways family members survive a major loss, and includes comedy as well as tragedy. Cynthia Nixon won the 2006 Tony Award for Best Performance by a Leading Actress in a Play for her performance as Becca in the New York production, and the play was nominated for several other Tony awards.

Rabbit Hole

A situation, journey, or process that is particularly strange, problematic, difficult, complex, or chaotic, especially one that becomes increasingly so as it develops or unfolds.

An allusion to “Alice’s Adventures in Wonderland” by Lewis Carroll, it is used especially in the phrase “(go) down the rabbit hole.”

Overhauling the current tax legislation is a rabbit hole I don’t think this administration should go down at this point.I’ve stayed away from drugs and alcohol since coming to college. I have an addictive personality, so I decided to just avoid that rabbit hole altogether.

What does rabbit hole mean?

Used especially in the phrase going down the rabbit hole or falling down the rabbit hole, a rabbit hole is a metaphor for something that transports someone into a wonderfully (or troublingly) surreal state or situation.

On the internet, a rabbit hole frequently refers to an extremely engrossing and time-consuming topic.

Where does rabbit hole come from?

Alice falling down a hole with a jar in hand
Alice’s Adventures in WonderLand

Literally, a rabbit hole is what the animal digs for its home. The earliest written record of the phrase dates back to the 17th century. But the figurative rabbit hole begins with Lewis Carrollโ€™s 1865 classic, Aliceโ€™s Adventures in Wonderland.

In its opening chapter, โ€œDown the Rabbit-Hole,โ€ Alice follows the White Rabbit into his burrow, which transports her to the strange, surreal, and nonsensical world of Wonderland.

Since then, Carrollโ€™s rabbit hole has proved a popular and useful reference. The Oxford English Dictionary finds the first allusive rabbit hole in a 1938 edition of The Yale Law Journal: โ€œIt is the Rabbit-Hole down which we fell into the Law, and to him who has gone down it, no queer performance is strange.โ€

Over much of the 20th century, rabbit hole has been used to characterize bizarre and irrational experiences. Itโ€™s especially used to reference magical, challenging, and even dangerous places or positions, similar to Carrollโ€™s topsy-turvy Wonderland.

Rabbit hole has many metaphorical applicationsโ€”from frustrating red tape to the mind-bending complexity of science to hallucinations during altered statesโ€”all united by a common sense of passing into some labyrinthine, logic-defying realm that, once entered, is hard to get out of.

One can fall down the rabbit hole of government bureaucracy, healthcare, obtaining a green card, tax law, the political economy of modern Japan, puberty, college admissions, or quantum mechanics.

If youโ€™re Neo in the hit film The Matrix, you can take the red pillโ€”a pill that shows you the truth, as opposed to the blue pill, which keeps you in ignoranceโ€”and โ€œsee how deep the rabbit hole goes.โ€

In a related note, some people literally take pills and go down the rabbit hole of a psychedelic drug trip.

But as Kathryn Schulz observed for The New Yorker in 2015, rabbit hole has further evolved in the information age: โ€œThese daysโ€ฆwhen we say that we fell down the rabbit hole, we seldom mean that we wound up somewhere psychedelically strange. We mean that we got interested in something to the point of distractionโ€”usually by accident, and usually to a degree that the subject in question might not seem to merit.โ€

Thanks to the abundance, variety, and instant access of content online, many fall down internet rabbit holes which are often spectacularly, and addictively, niche: scary stories, obscure conspiracy theories, or famous last meals, for instance.

Other rabbit holes tend to be opened up by specific services or social media, which serve users item after item, link after link: Wikipedia, Netflix, Amazon, Facebook, YouTube, and so forth.

These rabbit holes have become so common that people sometimes swap out rabbit for the name of the particular site, e.g. โ€œIโ€™ve fallen down an Instragram holeโ€ or โ€œIโ€™m falling down a wikihole.โ€

Who uses rabbit hole?

From formal documents to internet status updates, rabbit hole is a very popular and widespread expression. Unlike earlier iterations of the metaphor, internet rabbit holes convey less a sense of weirdness, disorientation, or difficulty than they do of an intensely captivating diversion.

Rabbit hole is also showing increasing use as a modifier, e.g. a rabbit-hole question or phenomenon.

Now… that we have a basic and broader understanding about this Hole and it’s rabbit that digged it ๐Ÿ˜‹๐Ÿ˜‚

Let me show you a journey that I took to get to know, understand, admire, be amazed and support the BitCorn everybody is so crazy about …

Bitcoin Glossary

Block

Blocks are found in the Bitcoin blockchain. Blocks connect all transactions together. Transactions are combined into single blocks and are verified every ten minutes through mining. Each subsequent block strengthens the verification of the previous blocks, making it impossible to double spend bitcoin transactions (see double spend below).

BIP

Bitcoin Improvement Proposal or BIP, is a technical design document providing information to the bitcoin community, or describing a new feature for bitcoin or its processes or environment which affect the Bitcoin protocol. New features, suggestions, and design changes to the protocol should be submitted as a BIP. The BIP author is responsible for building consensus within the community and documenting dissenting opinions.

Blockchain

The Bitcoin blockchain is a public record of all Bitcoin transactions. You might also hear the term used as a โ€œpublic ledger.โ€ The blockchain shows every single record of bitcoin transactions in order, dating back to the very first one. The entire blockchain can be downloaded and openly reviewed by anyone, or you can use a block explorer to review the blockchain online.

Block Height

The block height is just the number of blocks connected together in the block chain. Height 0 for example refers to the very first block, called the โ€œgenesis block.โ€

Block Reward

When a block is successfully mined on the bitcoin network, there is a block reward that helps incentivize miners to secure the network. The block reward is part of a โ€œcoinbaseโ€ transaction which may also include transaction fees. The block rewards halves roughly every four years; see also โ€œhalving.โ€

Change

Letโ€™s say you are spending $1.90 in your local supermarket, and you give the cashier $2.00. You will get back .10 cents in change. The same logic applies to bitcoin transactions. Bitcoin transactions are made up of inputs and outputs. When you send bitcoins, you can only send them in a whole โ€œoutput.โ€ The change is then sent back to the sender.

Cold Storage

The term cold storage is a general term for different ways of securing your bitcoins offline (disconnected from the internet). This would be the opposite of a hot wallet or hosted wallet, which is connected to the web for day-to-day transactions. The purpose of using cold storage is to minimize the chances of your bitcoins being stolen from a malicious hacker and is commonly used for larger sums of bitcoins.

Confirmation

A confirmation means that the bitcoin transaction has been verified by the network, through the process known as mining. Once a transaction is confirmed, it cannot be reversed or double spent. Transactions are included in blocks.

Cryptography

Cryptography is used in multiple places to provide security for the Bitcoin network. Cryptography, which is essentially mathematical and computer science algorithms used to encrypt and decrypt information, is used in bitcoin addresses, hash functions, and the blockchain.

Decentralized

Having a decentralized bitcoin network is a critical aspect. The network is โ€œdecentralized,โ€ meaning that itโ€™s void of a centralized company or entity that governs the network. Bitcoin is a peer-to-peer protocol, where all users within the network work and communicate directly with each other, instead of having their funds handled by a middleman, such as a bank or credit card company.

Difficulty

Difficulty is directly related to Bitcoin mining (see mining below), and how hard it is to verify blocks in the Bitcoin network. Bitcoin adjusts the mining difficulty of verifying blocks every 2016 blocks. Difficulty is automatically adjusted to keep block verification times at ten minutes.

Double Spend

If someone tries to send a bitcoin transaction to two different recipients at the same time, this is double spending. Once a bitcoin transaction is confirmed, it makes it nearly impossible to double spend it. The more confirmations that a transaction has, the harder it is to double spend the bitcoins.

Full Node

A full node is when you download the entire blockchain using a bitcoin client, and you relay, validate, and secure the data within the blockchain. The data is bitcoin transactions and blocks, which is validated across the entire network of users.

Halving

Bitcoins have a finite supply, which makes them scarce. The total amount that will ever be issued is 21 million. The number of bitcoins generated per block is decreased 50% every four years. This is called โ€œhalving.โ€ The final halving will take place in the year 2140.

Hash Rate

The hash rate is how the Bitcoin mining network processing power is measured. In order for miners to confirm transactions and secure the blockchain, the hardware they use must perform intensive computational operations which is output in hashes per second.

Hash (txid)

A transaction hash (sometimes referred to as a transaction ID or txid) is a unique identifier that can be used on any block explorer to look up all of the public details of a particular transaction. Every on-chain transaction has a unique hash made up of a long string of alphanumeric characters.

Mining

Bitcoin mining is the process of using computer hardware to do mathematical calculations for the Bitcoin network in order to confirm transactions. Miners collect transaction fees for the transactions they confirm and are awarded bitcoins for each block they verify.

Pool

As part of bitcoin mining, mining โ€œpoolsโ€ are a network of miners that work together to mine a block, then split the block reward among the pool miners. Mining pools are a good way for miners to combine their resources to increase the probability of mining a block, and also contribute to the overall health and decentralization of the bitcoin network.

Private Key

A private key is a string of data that shows you have access to bitcoins in a specific wallet. Think of a private key like a password; private keys must never be revealed to anyone but you, as they allow you to spend the bitcoins from your bitcoin wallet through a cryptographic signature.

Proof of Work

Proof of work refers to the hash of a block header (blocks of bitcoin transactions). A block is considered valid only if its hash is lower than the current target. Each block refers to a previous block adding to previous proofs of work, which forms a chain of blocks, known as a blockchain. Once a chain is formed, it confirms all previous Bitcoin transactions and secures the network.

Public Address

A public bitcoin address is cryptographic hash of a public key. A public address typically starts with the number โ€œ1.โ€ Think of a public address like an email address. It can be published anywhere and bitcoins can be sent to it, just like an email can be sent to an email address.

RBF

RBF stands for Replace By Fee, and refers to a method that allows a sender to replace a โ€œstuckโ€ or unconfirmed transaction with a new one that uses a higher fee. This is done to make sure a transaction confirms as quickly as possible. The โ€œreplacementโ€ transaction uses the same inputs as the original one. This is not considered a double spend, as the receiving address(es) typically remain the same.

Satoshi Nakamoto

Bitcoinโ€™s existence began with an academic paper written in 2008 by a developer under the name of Satoshi Nakamoto. Satoshi is the name used as the original inventor of Bitcoin.

Transaction

A transaction is when data is sent to and from one bitcoin address to another. Just like financial transactions where you send money from one person to another, in bitcoin you do the same thing by sending data (bitcoins) to each other. Bitcoins have value because itโ€™s based on the properties of mathematics, rather than relying on physical properties (like gold and silver) or trust in central authorities, like fiat currencies. 

Wallet

Just like with paper dollars you hold in your physical wallet, a bitcoin wallet is a digital wallet where you can store, send, and receive bitcoins securely. There are many varieties of wallets available, whether youโ€™re looking for a web or mobile solution. Ideally, a bitcoin wallet will give you access to your public and private keys. This means that only you have rightful access to spend these bitcoins, whenever you choose to.

Most people misunderstand what bitcoin miners actually do, and as a result they don’t fully grasp the level of security provided by bitcoin’s hashrate.

In this article, we’ll explain proof of work in a non-technical way so that youโ€™ll be able to counter the misinformation about supercomputers and quantum computers attacking the Bitcoin network in the future. 

Simply put, mining is a lottery to create new blocks in the Bitcoin blockchain. There are two main purposes for mining:

  1. To permanently add transactions to the blockchain without the permission of any entity.
  2. To fairly distribute the 21 million bitcoin supply by rewarding new coins to miners who spend real world resources (i.e. electricity) to secure the network.

To understand what is actually happening in this lottery system, let’s look at a simple analogy where every Bitcoin hash is equivalent to a dice roll.

Luck, Gambling, and SHA-256

Imagine that miners in the Bitcoin Network are all individuals gambling at a casino. In this example, each of these gamblers have a 1000 sided dice. They roll their die as quickly as possible, trying to get a number less than 10. Statistically, this may take a very long time, but as more gamblers join the game, the time it takes to hit a number less than 10 gets reduced. In short, more gamblers equals quicker rounds.

Once somebody successfully rolls a number less than 10, all gamblers at the table can look down and verify the number. This lucky gambler takes the prize money and the next round begins.

Ultimately, the process of mining bitcoin is very similar. All miners on the network are using Application Specific Integrated Circuits (ASICs), which are specialized computers designed to compute hashes as quickly as possible.

To โ€œcompute a hashโ€ simply means plugging any random input into a mathematical function and producing an output.

More hashes per second (i.e. higher hashrate) is equivalent to more dice rolls per second, and thus a greater probability of success.

Miners propose a potential Bitcoin block of transactions, and use this for an input. The block is plugged into the SHA256 hash function which yields a fixed-sized output, known as a hash. A single hash can be computed in less than a millisecond, as it involves no complex math.

If the hash value is lower than the Bitcoin Network difficulty, then the miner who proposed the block wins. If not, then the miner continues trying by computing more hashes.

The successful minerโ€™s block is then added to the blockchain, the miner is rewarded with newly issued bitcoin for their work, and the โ€œnext roundโ€ begins.

AutoDidacticism

a.k.a Self-Learning

Autodidacts take learning into their own hands

Autodidacticismย (alsoย autodidactism) orย self-educationย (alsoย self-learningย andย  self-teaching) isย educationย without the guidance of masters (such asย teachersย  andย professors) orย institutionsย (such as schools).

Generally,ย autodidactsย are individuals who choose the subject they will study, their studying material, and the studying rhythm and time.

Autodidacts may or may not haveย formal education, and their study may be either a complement or an alternative to formal education.

Manyย notable contributionsย have been made by autodidacts.

Etymology

The term has its roots in theย Ancient Greekย  wordsย ฮฑแฝฯ„ฯŒฯ‚ย (autรณs,ย lit.โ€‰’self’) andย ฮดฮนฮดฮฑฮบฯ„ฮนฮบฯŒฯ‚ (didaktikos,ย lit.โ€‰’teaching’).

The related termย didacticismย defines an artisticย  philosophy of education.

“My advice, as in everything, is to read widely and think for yourself.

We need more dissent and less dogma.”

Camille Paglia

“For those of you who may be homeschooled: high school is that four-year asylum where they put teenagers because we have no idea what else to do with them.”

Anthony Esolen

“There is nothing to be gained by pretending that academic involvement is necessary, or even always desirable, in the quest for truth and knowledge.”

Christopher Langan

“Drop out of school before your mind rots from exposure to our mediocre educational system.

Forget about the Senior Prom and go to the library and educate yourself if you’ve got any guts.

Some of you like Pep rallies and plastic robots who tell you what to read.

Forget I mentioned it.

This song has no message.

Rise for the flag salute.”

Frank Zappa, liner notes for song “Hungry Freaks Daddy” on the albumย “Freak Out!“

“That man is intellectually of the mass who, in the face of any problem, is satisfied with thinking the first thing he finds in his head.

On the contrary, the excellent man is he who condemns what he finds in his mind without previous effort, and only accepts as worthy of him what is still far above him and what requires a further effort in order to be reached.”

Josรฉ Ortega y Gasset,ย The Revolt of the Massesย (1929)

“When brought to the proletariat from the capitalist class, science is invariably adapted to suit capitalist interests.

What the proletariat needs is a scientific understanding of its own position in society.

That kind of science a worker cannot obtain in the officially and socially approved manner. …

For this reason he must be completely self-taught.”

Karl Kautsky

“Only the autodidacts are free.”

Nassim Nicholas Taleb,ย “Antifragile: Things That Gain from Disorder”
