Ano ang Bitcoin? (BTC)

Ang Beginner's Guide


Ang Bitcoin ay isang imbensyon na, sa unang pagkakataon sa kasaysayan, ay nagbigay-daan sa isang grupo ng mga user ng software na lumikha at mamahala ng digital na supply ng pananalapi sa labas ng kontrol ng anumang gobyerno o bangko. 

Isa itong rebolusyonaryong ideya noong ipinakilala noong 2009, ang Bitcoin ay may mga implikasyon na nagsisimula pa lamang maunawaan at tuklasin ng mga technologist at ekonomista ngayon. 

Ito ay nangangahulugan na, depende sa kung sino ang iyong tatanungin, maaari kang makakuha ng iba't ibang mga sagot sa mga tanong tulad ng “Ano ang Bitcoin? at “Bakit may halaga ang mga bitcoin?” 

Upang panimula, nakakatulong na isipin ang Bitcoin bilang isang software protocol tulad ng mga ginagamit mo sa araw-araw – isipin ang SMTP (na tumutulong sa pagruta ng iyong mga email) at HTTP (na nagsisiguro na ang web content na hinihiling mo mula sa iyong browser ay maihatid sa iyo ng mga server). 

Ang Bitcoin protocol ay nagbibigay-daan sa mga computer na nagpapatakbo ng software nito na pamahalaan ang isang set ng data (ang blockchain) at ipatupad ang isang set ng mga panuntunan na ginagawang mahirap at mahalaga ang data na ito (bitcoins

Bilang mahalagang building blocks nito, ginagamit ng Bitcoin protocol ang: 

  1. Public-key cryptography – Ang wallet software ay nagtatalaga sa mga may-ari ng bitcoin ng parehong pampublikong key (na ginagamit ng protocol upang patunayan na pagmamay-ari mo ang bitcoin) at isang pribadong key (isang uri ng password na, kung na-secure nang maayos, ay magbibigay garantiya na ikaw lamang ang mayroong access sa iyong bitcoin).
  2. Peer-to-peer networking – Ang mga node (mga computer na nagpapatakbo ng software) ay nagsusuri ng mga transaksyon upang matiyak na sinusunod ng mga ito ang mga panuntunan ng software. Ang mga miners (node ​​na gumagamit ng mga espesyal na computer chips) ay nakikipagkumpitensya para sa karapatang i-batch ang mga transaksyong ito sa mga blocks na pana-panahong idinaragdag sa blockchain.
  3. Isang may hangganan na supply – Ayon sa mga panuntunan ng software, 21 milyong bitcoin lang ang maaaring gawin, isang limitasyon na nagbibigay ng halaga sa mga bitcoin.

Ang Bitcoin blockchain ay isang buong talaan ng kasaysayan ng network na na-validate ng mga indibidwal na nagpapatakbo ng Bitcoin software (node). Tinitiyak nito na hindi tulad ng karamihan sa mga digital na data, na maaaring malayang makopya at mabago, ang mga ito ay hindi maaring gawin sa bitcoin. 

Dahil ang mga bitcoin ay kakaunti, nahahati at naililipat, ang mga bitcoin ay ginagamit bilang salapt.


Sino ang Lumikha ng Bitcoin?

While Bitcoin can safely claim to have created the world’s first successful cryptocurrency, its technology is built on decades of ideas for how cryptography could help create digital money.

This includes such formative projects as:

B-money – A proposed anonymous, distributed digital cash system

Bit Gold – An attempt to create a type of scarce online commodity

eCash – The first major attempt to create anonymous online payments

HashCash – A proof-of-work system designed to prevent email spam

In 2006, “Satoshi Nakamoto,” a still pseudonymous person or group, began writing the code for a new digital cash system called “Bitcoin.” 

This was then followed by the publication of a white paper explaining this proposed system in 2008, and the release of Bitcoin 0.1, the first version of the software, on January 9, 2009.

Nakamoto authored a trove of emails and forum posts offering his or her thoughts about the future of Bitcoin prior to leaving the project in 2011. Today, hundreds of developers contribute to Bitcoin’s code, where they make everything from routine bug fixes to efficiency improvements.

Ano ang nagpapa-desentralisado sa Bitcoin?


It is the belief of many technologists that Bitcoin’s fundamental property – i.e. what makes it different from other digital money systems – is that it’s network is decentralized.

To fully understand the idea behind decentralization and why it’s so important, it’s helpful to consider how banking works today.

You likely deposit your paycheck regularly into a bank account. In this case, the bank provides you the means to use your money (via its ATMs, payment cards and checks), while keeping it safe from theft (with security guards, vaults and alarms).

In our example, banks act as central authorities. They are third parties that facilitate transactions between individuals and businesses. Essentially, banks act as middlemen to your transactions. They then provide this same service for all customers, which gives them control of a giant supply of other people’s money. 

With this power, they can easily change the rules. Your bank might lend your money without your permission, decide not to process a transaction for you or even deny you access to your money. Governments and criminals can also seize your data and money from banks.

The idea behind Bitcoin is to have a system where there is no middleman or central authority. Only you have control of your money and your transactions cannot be denied.  

Bitcoin is “decentralized” because its software allows anyone to trustlessly verify the authenticity and scarcity of the bitcoins they are receiving. In this way, Bitcoin’s decentralization solves the trust issue inherent with centralized money managers. If any one computer stops performing its function, another can take its place. 

Bitcoin developers tend to consider the network more or less decentralized depending on how much it costs for the average user to synchronize a node with the network, and they propose changes to the protocol according to how it might impact this process.


Paano Gumagana ang Bitcoin?

Totoo sa disenyo nito, ang mga bitcoin ngayon ay maaaring ipadala sa pagitan ng dalawang user ng walang kailangang tagapamagitan.

Kung bibigyan mo ang isang tao ng dolyar, magkakameron sila ng dolyar at ikaw ay mawawalan. Nabigyan mo ang isang tao ng isang bagay na may halaga, at tinanggap nila iyon. Ganun din ang ginagawa sa sa bitcoin . 

Subalit, ikaw marahil ay nag tatanong, paano ang lahat ng computer na nagpapatakbo ng network? Ano ang pumipigil sa kanila na ma-break ang patakaran ng software nito at magnakaw ng pera? Mahalaga, mga insentibo.

Para maimpluwensyahan ang legder ng bitcoin, ang isang hacker ay kailangang makontrol ang hindi bababa sa isang pangatlong mining hardware. Ngunit ilang miner nito ang mananalo ng lion's share ng bagong mga bitcoin, hindi ito mapupunta sa kanilang pinakamainam na interes sa pag-atake ng network.

Para sa isang bagay, ang mataas na halaga ng Bitcoin ang nagpapamahal sa mining. Upang makipagkompitensya sa bagong BTC, ang mga miner ay dapat gumamit ng specialized na hardware at murang kuryente upang lutasin ang mga hash at mag-propose ng mga bagong block. 

Ito ay hindi madaling karera para manalo- ang computational na kapangyarihan ng pakikipag-kompitensya sa pag-mine ng bagong BTC ay mas mataas ngayon kaysa mga Google data center. Sa pagsasanay, nangangahulugan ito na habang posibleng manipulahin a Bitcoin blockchain, ito ay hindi praktikal sa ekonomiya.

Ano ang Nagbibigay ng Halaga sa BTC?


Bitcoin shares many of the characteristics that give traditional commodities and government monies value – scarcity, durability, portability, divisibility, fungibility and acceptability. 

It can even be argued that BTC has an advantage over government monies and commodities in many of these categories.

Scarcity

BTC supply is more limited than silver and gold supply, as there will only ever be 21 million BTC introduced to the network’s economy.

When the first block was mined in 2009, 50 BTC were released. Through this process, more than 18 million BTC have been made available as of 2020.

The number of BTC released in each block is cut in half roughly every four years to keep the total supply finite, in an event known as the halving (or halvening). 

Durability

Any form of cash needs to be durable enough to be used over and over again. BTC private keys are numbers and letters, which can be stamped into stainless steel, backed up or divided into pieces, adding to their durability. 

Portability

With BTC, you can carry around all your wealth on a flash drive, memorized in your brain or transfer it instantly via the internet. 

Divisibility

All currencies carry denominations so people can purchase goods that carry differing values. U.S. dollars, for example, are divisible from $100 bills down to pennies. 

BTC, too, is divisible, and is able to subdivided up to the eighth decimal place. The smallest unit of currency is called a Satoshi after Bitcoin’s creator. 1 BTC equals 100,000,000 satoshis (sats).

Fungibility

All units of money must be as uniform and interchangeable. 

Like paper cash or gold, depending on how you received your BTC it will have varying degrees of fungibility. BTC that was involved in a crime, for example, may not be accepted by exchanges or merchants. (This remains an active area of research for Bitcoin developers.)

Acceptability

For something to store value, people need to recognize and accept that it’s worth something.

There are currently thousands of individuals and vendors accepting Bitcoin payments, from Microsoft to Subway, and thousands of other small businesses taking payments and donations with Bitcoin.

You can also buy and sell BTC for other cryptocurrencies alongside more traditional currencies at exchanges like Kraken, which are online 24/7 to match your trades.
