We break down the basics of Bitcoin, discuss its history, and explain key concepts, providing a solid foundation for anyone new to the world of cryptocurrency. What is Bitcoin? Definition: General public perception: Is Bitcoin a scam, internet money, or crypto? Hosts' definitions: Insights from DEE A & RA George. Whitepaper Definition: Peer-to-peer electronic cash system, as defined by Satoshi Nakamoto. Why it Matters: Challenges with the current banking system vs. Bitcoin's peer-to-peer model. A personal perspective on the inefficiencies of traditional systems like KYC and large-sum transactions. The Basics of Bitcoin 21 Million Limit: Exploring the concept of demand vs. supply. Bitcoin Halving: An easy breakdown of how and why Bitcoin rewards are halved every 4 years: History of Bitcoin Bitcoin wasn't the first cryptocurrency; others like eCash, B-Money, BitGold, and Hashcash came before. The Double-Spending Problem and how Bitcoin solved it using cryptography, hashing algorithms, and mathematics (SHA-256). Key Concepts of Bitcoin Peer-to-Peer: A comparison with fiat systems and real-world examples (e.g., Dubizzle, Facebook Marketplace). Electronic Cash System: Bitcoin Mining Simplified explanation: Miners solve puzzles to verify transactions, using energy in a process called Proof of Work (PoW). Pillars of Bitcoin (Open Blockchain) Open Source: Transparent source code available on GitHub. Permissionless: No age or location restrictions for users. Borderless: Seamless transactions worldwide. Censorship-Resistant: Miners update transactions without validating their purposes. Publicly Verifiable: Bitcoin transactions are traceable via Blockchain Explorer, making illicit activities detectable. Comparison to CBDCs CBDCs are not peer-to-peer and are controlled by central banks. Bitcoin provides transparency, while CBDCs allow selective verification and potential double-spending. This session breaks down the barriers to understanding Bitcoin, helping beginners grasp why it's often called the future of money.

“If you want to understand someone, an individual, you kind of need to understand what their life has been like, where they came from…and I think the same is true for Bitcoin, if you really want to understand Bitcoin, you need to understand where it came from.”— Aaron van WirdumAaron Van Wirdum is a Bitcoin journalist and author of ‘The Genesis Book'. In this interview, we discuss the history of Bitcoin, including the importance of consensus algorithms and public key cryptography, early scepticism towards Bitcoin from cypherpunks, Satoshi's decision to remain anonymous, and its fixed monetary policy. We also talk about the influence of Austrian economics on Bitcoin's foundation, and the significance of privacy in digital transactions. - - - - The esteemed journalist Aaron Van Wirdum has authored a new book on the origins of Bitcoin called ‘The Genesis Book'. Our discussion naturally focuses on the influence of Austrian economics: Aaron explains how Hayek's ideas about money supply were instrumental in shaping Bitcoin's principles, and how the cypherpunk movement of the 90s aspired to create technologies beyond government control - echoing Hayek's vision of market-driven money.We examine the reasons behind the failure of early digital cash projects and the lessons learned that paved the way for Bitcoin's success. Hashcash and its Proof of Work (PoW) concept, developed by Adam Back, was a key innovation contributing to the creation of Bitcoin.

So, here's my Top 100 snippets of knowledge for blockchain: Blockchains use public key methods to integrate digital trust. Bob signs for a transaction with his private key, and Alice proves this with Bob's public key. The first usable public key method was RSA — and created by Rivest, Shamir and Adleman. It was first published in 1979 and defined in the RSA patent entitled “Cryptographic Communications System and Method”. Blockchains can either be permissioned (requiring rights to access the blockchain) or permissionless (open to anyone to use). Bitcoin and Ethereum are the two most popular permissionless blockchains, and Hyperledger is the most popular permissioned ledger. Ralph Merkle — the boy genius — submitted a patent on 5 Sept 1979 and which outlined the Merkle hash. This is used to create a block hash. Ralph Merkle's PhD supervisor was Martin Hellman (famous as the co-creator of the Diffie-Hellman method). David Chaum is considered as founders of electronic payments, and, in 1983, created ECASH, along with publishing a paper on “Blind signatures for untraceable payments”. Miners gather transactions on a regular basis, and these are added to a block and where each block has a Merkle hash. The first block on a blockchain does not have any previous blocks — and is named the genesis block. Blocks are bound in a chain, and where the previous, current and next block hashes are bound into the block. This makes the transactions in the block immutable. Satoshi Nakamoto worked with Hal Finney on the first versions of Bitcoin, and which were created for a Microsoft Windows environment. Craig Steven Wright has claimed that he is Satoshi Nakamoto, but this claim has never been verified. Most blockchains use elliptic curve cryptography — a method which was created independently by Neal Koblitz and Victor S. Miller in 1985. Elliptic curve cryptography algorithms did not take off until 2004. Satoshi selected the secp256k1 curve for Bitcoin, and which gives the equivalent of 128-bit security. The secp256k1 curve uses the mapping of y²=x³ + 7 (mod p), and is known as a Short Weierstrass (“Vier-strass”) curve. The prime number used with secp256k1 is ²²⁵⁶−²³²−²⁹−²⁸−²⁷−²⁶−²⁴−1. Satoshi published a 9-page paper entitled “Bitcoin: A Peer-to-Peer Electronic Cash System” White Paper on 31 Oct 31, 2008. In 1997, Adam Black introduce the concept of Proof of Work of Hashcash in a paper entitled, “Hashcash — a denial of service countermeasure.” This work was used by Satoshi in his whitepaper. Satoshi focused on: a decentralized system, and a consensus model and addressed areas of double-spend, Sybil attacks and Eve-in-the-middle. The Sybil attack is where an adversary can take over the general consensus of a network — and leads to a 51% attack, and where the adversary manages to control 51% or more of the consensus infrastructure. Satoshi used UK spelling in his correspondence, such as using the spelling of “honour”. The first Bitcoin block was minted on 3 Jan 2009 and contained a message of “Chancellor on brink of second bailout for banks” (the headline from The Times, as published in London on that day). On 12 Jan 2009, Satoshi sent the first Bitcoin transaction of 50 BTC to Hal Finney [here]. A new block is created every 7–10 minutes on Bitcoin. In Aug 2023, the total Bitcoin blockchain size is 502 GB. As of Aug 2023, the top three cryptocurrencies are Bitcoin, Ether, and Tether. Bitcoin has a capitalization of $512 billion, Ether with $222 billion, and Tether at $83 billion. The total cryptocurrency capitalisation is $1.17 trillion. The original block size was 1MB for Bitcoin, but recently upgraded to support a 1.5MB block — and has around 3,000 transactions. Currently the block sizes are more than 1.7MB. Bitcoin uses a gossip protocol — named the Lightning Protocol — to propagate transactions. A Bitcoin wallet is created from a random seed value. This seed value is then used to create the 256-bit secp256k1 private key. A wallet seed can be converted into a mnemonic format using BIP39, and which uses 12 common words. This is a deterministic key, and which allows the regeneration of the original key in the correct form. BIP39 allows for the conversion of the key to a number of languages, including English, French and Italian. A private key in a wallet is stored in a Wif format, and which is a Base58 version of the 256-bit private key. The main source code for the Bitcoin blockchain is held at https://github.com/bitcoin, and is known as Bitcoin core. This is used to create nodes, store coins, and transactions with other nodes on the Bitcoin network. A 256-bit private key has 115,792 billion billion billion billion billion billion billion billion different keys. A public Bitcoin ID uses Base58 and has a limited character set of ‘123456789ABCDEFGHJKLMN PQRSTUVWXYZabcdefghijkmno pqrstuvwxyz', where we delete ‘0' (zero), ‘l' (lowercase ‘l'), and ‘I' (capital I) — as this can be interpreted as another character. In Bitcoin and Ethereum, a private key (x) is converted to a public key with x.G, and where G is the base point on the secp256k1 curve. An uncompressed secp256k1 public key has 512 bits and is an (x,y) point on the curve. The point starts with a “04”. A compressed secp256k1 public key only stores the x-co-ordinate value and whether the y coordinate is odd or even. It starts with a “02” if the y-co-ordinate is even, otherwise it starts with a “03”. In 1992, Eric Hughes, Timothy May, and John Gilmore set up the cypherpunk movement and defined, “We the Cypherpunks are dedicated to building anonymous systems. We are defending our privacy with cryptography, with anonymous mail forwarding systems, with digital signatures, and with electronic money.” In Ethereum, the public key is used as the identity of a user (a.G), and is defined as a hexademical value. In Bitcoin, the public ID is created from a SHA256 hash of the public key, and then a RIPEMD160 of this, and then covered to Base58. In computing the public key in ECC of a.G, we use the Montgomery multiplication method and which was created by Peter Montgomery in 1985, in a paper entitled, “Modular Multiplication without Trial Division.” Elliptic Curve methods use two basic operations: point address (P+G) and point doubling (2.P). These can be combined to provide the scalar operation of a.G. In 1999, Don Johnson Alfred Menezes published a classic paper on “The Elliptic Curve Digital Signature Algorithm (ECDSA)”. It was based on the DSA (Digital Signature Algorithm) — created by David W. Kravitz in a patent which was assigned to the US. The core signature used in Bitcoin and Ethereum is ECDSA (Elliptic Curve Digital Signature Algorithm), and which uses a random nonce for each signature. The nonce value should never repeat or be revealed. Ethereum was first conceived in 2013 by Vitalik Buterin, Gavin Wood, Charles Hoskinson, Anthony Di Iorio and Joseph Lubin. It introduced smaller blocks, an improved proof of work, and smart contracts. Bitcoin is seen as a first-generation blockchain, and Ethereum as a second-generation. These have been followed by third-generation blockchains, such as IOTA, Cardano and Polkadot — and which have improved consensus mechanisms. Bitcoin uses a consensus mechanism which is based on Proof-of-Work, and where miners focus on finding a block hash that has a number of leading “0”s. The difficulty of the mining is defined by the hashing rate. At the current time, this is around 424 million TH/s. There are around 733,000 unique Bitcoin addresses being used. Satoshi defined a reward to miners for finding the required hash. This was initially set at 50 BTC, but was set to half at regular intervals. On 11 January 2021, it dropped from 12.5 BTC to 6.2 BTC. Bitcoin currently consumes around 16.27 GWatts of power each year to produce a consensus — equivalent to the power consumed by a small country. In creating bitcoins, Satoshi created a P2PKH (Pay to Public Key Hash) address. These addresses are used to identify the wallet to be paid and links to the public key of the owner. These addresses start with a ‘1'. In order to support the sending of bitcoins to and from multiple addresses, Bitcoin was upgraded with SegWit (defined in BIP141). The wallet address then integrates the pay-to-witness public key hash (Pay to script hash — P2SH). These addresses start with a ‘3'. Ethereum uses miners to undertake work for changing a state and running a smart contract. They are paid in “gas” or Ether and which relates to the amount of computation conducted. This limits denial of service attacks on the network and focuses developers on creating efficient code. Ethereum supports the creation of cryptocurrency assets with ERC20 tokens — and which are FT (Fungible Tokens). For normal crypto tokens (ERC-20) we use, there is a finite number of these, and each of these is the same. Ethereum creates NFTs (Non-Fungible Tokens) with ERC721 tokens. We mint these each time and each is unique. Solidity is the programming language used in Ethereum, while Hyperledger can use Golang, Node.js and Java. For Ethereum, we compile Solidity code into EVM (Ethereum Virtual Machine) code. This is executed on the blockchain. Blockchain uses the SHA-256 hash for transaction integrity. Ethereum uses the Keccak hash is used to define the integrity of a transaction. This is based on SHA-3, and differs slightly from Keccak. The Keccak hash family uses a sponge function and was created by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche, and standardized by NIST in August 2015 as SHA-3. The DAO is a decentralized autonomous organization (DAO) for the Ethereum blockchain and was launched in 2016. In 2016, DAO raised $150 million through a token sale but was hacked and funds were stolen. This resulted in a forking of the blockchain: Ethereum and Ethereum Classic. Non-interactive Zero Knowledge Proofs (NI-ZKP) allow an entity to prove that they have knowledge of something — without revealing it. A typical secret is the ownership of a private key. NI-ZKPs involve a prover (Peggy), a verifier (Victor) and a witness (Wendy) and were first defined by Manuel Blum, Paul Feldman, and Silvio Micali in their paper entitled, “Non-interactive zero-knowledge and its applications”. Popular ZKP methods include ZK-SNARKs (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) and ZK-STARKs (Zero-Knowledge Scalable Transparent Argument of Knowledge). Bitcoin and Ethereum are pseudo-anonymised, and where the sender and recipient of a transaction, and its value, can be traced. Privacy coins enable anonymous transactions. These include Zcash and Monero. In 1992, David Chaum and Torben Pryds Pedersen published “Wallet databases with observers,” and outlined a method of shielding the details of a monetary transaction. In 1992, Adi Shamir (the “S” in RSA) published a paper on “How to share a secret” in the Communications of the ACM. This supported the splitting of a secret into a number of shares (n) and where a threshold value (t) could be defined for the minimum number of shares that need to be brought back together to reveal the secret. These are known as Shamir Secret Shares (SSS). In 1991, Torbin P Pedersen published a paper entitled “Non-interactive and information-theoretic secure verifiable secret sharing” — and which is now known as Pedersen Commitment. This is where we produce our commitment and then show the message that matches the commitment. Distributed Key Generation (DKG) methods allow a private key to be shared by a number of trusted nodes. These nodes can then sign for a part of the ECDSA signature by producing a partial signature with these shares of the key. Not all blockchains use ECDSA. The IOTA blockchain uses the EdDSA signature, and which uses Curve 25519. This is a more lightweight signature version, and has better support for signature aggregation. It uses Twisted Edwards Curves. The core signing method used in EdDSA is based on the Schnorr signature scheme and which was created by Claus Schnorr in 1989. This was patented as, a “Method for identifying subscribers and for generating and verifying electronic signatures in a data exchange system”. The patent ran out in 2008. Curve 25519 uses the prime number of ²²⁵⁵-19 and was created by Daniel J. Bernstein. Peter Shor defined that elliptic curve methods can be broken with quantum computers. To overcome the cracking of the ECDSA signature from quantum computers, NIST are standardising a number of methods. At present, this focuses on CRYSTALS-Dilithium, and which is a lattice cryptography method. Bulletproofs were created in 2017 by Stanford's Applied Cryptography Group (ACG). They define a zero-knowledge proof as where a value can be checked to see it lies within a given range. The name of “bulletproofs” is defined as they are short, like a bullet, and with bulletproof security assumptions. While Bitcoin can take up to 7–10 minutes to mine a new block and create a consensus, newer blockchains, such as IOTA, can give an almost instantaneous consensus. Banks around the world are investigating CBDC (Central Bank Digital Currency) and which is not a cryptocurrency but a way to quickly define a consensus on a transaction. Homomorphic encryption methods allow for the processing of encrypted values using arithmetic operations. A public key is used to encrypt the data, and which can then be processed using an arithmetic circuit on the encrypted data. The owner of the associated private key can then decrypt the result. Some traditional public key methods enable partial homomorphic encryption. RSA and ElGamal allow for multiplication and division, whilst Pailier allows for homomorphic addition and subtraction. Full homomorphic encryption (FHE) supports all of the arithmetic operations and includes Fan-Vercauteren (FV) and BFV (Brakerski/Fan-Vercauteren) for integer operations and HEAAN (Homomorphic Encryption for Arithmetic of Approximate Numbers) for floating point operations. Most of the Full Homomorphic encryption methods use lattice cryptography. Some blockchain applications use Barreto-Lynn-Scott (BLS) curves which are pairing friendly. They can be used to implement Bilinear groups and which are a triplet of groups (G1, G2 and GT), so that we can implement a function e() such that e(g1^x,g2^y)=gT^{xy}. Pairing-based cryptography is used in ZKPs. The main BLS curves used are BLS12–381, BLS12–446, BLS12–455, BLS12–638 and BLS24–477. An accumulator can be used for zero-knowledge proof of knowledge, such as using a BLS curve to create to add and remove proof of knowledge. Open Zeppelin is an open-source Solidity library that supports a wide range of functions that integrate into smart contracts in Ethereum. This includes AES encryption, Base64 integration and Elliptic Curve operations. Metamask is one of the most widely used blockchain wallets and can integrate into many blockchains. Most wallets generate the seed from the operating system and where the browser can use the Crypto.getRandomValues function, and compatible with most browsers. Solidity programs can be compiled with Remix at remix.ethereum.org. The main Ethereum network is Ethereum Mainnet. We can test smart contracts on Ethereum test networks. Current networks include sepolia.etherscan.io and goerli.net. Ether can be mined for test applications from a faucet, such as faucet.metamask.io. This normally requires some proof of work to gain the Ether — in order to protect against a Denial of Service against the Faucet. The private key can be revealed from two ECDSA signatures which use the same random nonce value. Polkadot is a blockchain which allows blockchains to exchange messages and perform transactions. The proof of work method of creating is now not preference because of the energy that it typically uses. Many systems now focus on proof of stack (PoS). A time-lock puzzle/Proof of Work involves performing a computing task which has a given cost and which cannot be cheated again. This typically involves continual hashing or continual squaring. The Chia blockchain network uses both Proof of Space (PoS) and Proof of Time (PoT). The PoS method makes use of the under-allocation of hard-disk space. With a Verifiable Delay Function (VDF), we can prove that a given amount of work has been done by a prover (Peggy). A verifier (Victor) can then send the prover a proof value and compute a result which verifies the work has been done, with the verifier not needing to do the work but can still prove the work has been done. A Physical Unclonable Functions (PUFs) is a one-way function which creates a unique signature pattern based on the inherent delays within the wireless and transistors. This can be used to link a device to an NFT. In Blockchain applications, we can use Non-interactive zero-knowledge (NIZK) proofs for the equality (EQ) of discrete logarithms (DL) — DLEQ. With this — in discrete logarithms — we have
Jameson Lopp has been building multisig Bitcoin wallets since 2015. He is the founder and CTO of Casa and also founded Mensa's Bitcoin Special Interest Group, the Triangle Bitcoin & Business meetup, and several open source Bitcoin projects. He enjoys researching various aspects of the ecosystem and giving presentations about what he has learned the hard way while trying to write robust software that can withstand both adversaries and unsophisticated users. In Value Stack Episode 40, we discuss the history of email and spam prevention, and the actions / missteps that led to centralizing forces of the Mail Protocol, SMTP, into the control of a few gatekeepers over time. We expand on whether these same forces and gatekeepers are developing and might be present in the Bitcoin protocol today, if the similar missteps are being made, or if we've already fought those battles and learned from previous mistakes.

“It's a competition of ideas… and it's a collaborative competition of ideas. So if you propose an organised set of ideas as a proposal, some parts of them might end up being good and used, and some parts might not. And you just have to be open to that.”— Adam BackAdam Back, an original cypherpunk, inventor of Hashcash and co-founder and CEO of Blockstream. We discuss the controversy around BIP 119: the soft fork proposal aiming to add “covenants” to Bitcoin. We also talk about the collapse of Luna. - - - - Flexible smart contracts are a USP of Ethereum and other blockchains. Currently, Bitcoin only enables basic smart contract functionality, such as a timelock that specifies when a transaction can be spent. BIP 119 proposes to add more flexibility for applying restrictions to transactions via a new programme operation code (opcode) called CheckTemplateVerify (CTV).CTV would enable conditions on spending UTXOs that would limit, not when they are spent, but how. These are referred to as “covenants”. It is envisaged CTV could significantly enhance Bitcoin by enabling a raft of new and powerful applications to be developed; these could bring new security, privacy and scalability benefits. The concern is that CTV is a significant change and could open up potential unknown security risks, or that if this functionality is desirable, it could be possible be better achieved with a different technical approachBIP119 has been authored and enthusiastically promoted by Bitcoin developer, Jeremy Rubin. It has been around now for 2 years, and whilst Rubin has generated support for BIP119, he has also faced criticism from prominent Bitcoiners for his approach and so far there doesn't seem to be consensus among the protocol development community on implementing the proposal.The consideration, approval and activation of changes to Bitcoin are methodical and slow. Further, such changes normally involve the development of competing ideas, and a collaborative approach to combine the best elements from these efforts. Notable critics feel that BIP119 is being too forcefully promoted and that more time is needed to test and consider alternatives.The pressure to innovate will always be there. The issue at hand is Bitcoin's USP: it has never been hacked. This has been hard-won. So it seems BIP119 isn't going to get a formal consensus at the moment. Rubin, however, could bypass the Core developers and implement a UASF. Could we again be about to test the limits of Bitcoin's rough consensus process?

On this episode of Speaking of Bitcoin, join hosts Adam B. Levine, Andreas M. Antonopoulos, Stephanie Murphy and Jonathan Mohan for a discussion about the origins and evolution of Bitcoin maximalism. Bitcoin maximalists – the self-described pro-Bitcoin, anti-altcoin faithful – have been around for longer than most modern crypto projects. The term was coined by Vitalik Buterin prior to Ethereum's release. Buterin intended the term to be a direct criticism of individuals with an unwavering view that Bitcoin was the only true option for cryptographic token use-cases. In this episode as we explore the phenomenon's' motivation and roots, we also draw from Speaking of Bitcoin's extensive library. It features the very first recorded explanation of why there should only be one cryptocurrency and why should be bitcoin as explained by Hashcash inventor and bitcoin developer Adam Back . That clip is excerpted from episode 77 (December 2013) before Adam became personally involved. It's a fascinating journey and one you won't want to miss. Credits Today's show featured Andreas M.

In this episode we'll talk about an important piece within the operation of Bitcoin, that is the proof-of-work, in which Back has an important influence. We also talked about the current situation of mining, and the latest announcements from Blockstream regarding its intention to create mining hardware. Back is a pioneer of cryptography, and we owe him the first successful product where proof of work was used. We are talking about Hashcash, which implemented this technology to reduce or prevent spam in emails, and not for the same purposes as in Bitcoin. Follow mr.

Muy buenos días, Gracias a Dios por dejarme realizar un programa más de Finanzas Online, el programa, el podcast donde te comparto recomendaciones, sugerencias, conceptos, noticias, estrategias … todo lo que sea necesario para que hagas crecer tu dinero. Cuando iniciaste tu emprendimiento los ingresos eran pocos y apenas si te alcanzaba para cubrir tus gastos. Pero pasado el tiempo comienzas a tener utilidad y es el momento de pensar en invertir, para tener un futuro más controlado resultado de buenas decisiones. La gran diferencia que existe entre el emprendedor y el empresario es que el empresario invierte para hacer crecer su negocio y su dinero. Eso es lo que encontrarás aquí en Finanzas Online. A lo largo de los episodios te compartiré información y sobre todo consejos prácticos para que hagas crecer tu dinero… esto es Finanzas Online. Episodio 137 del martes 23 de marzo de 2021 La dedicatoria de hoy es para todos aquellos que hacen maratones de películas, este fin de semana en casa hicimos el nuestro, vimos todas las películas de la saga de Crepúsculo jejeje. Si también tuviste un fin de semana de maratón. Desde mi covacha te envío un enorme Podabrazo. Sin más .... FINANZAS A LA OBRA ... Tengo que ser muy honesto y sincero, respecto al tema de hoy, las criptomonedas. Cuando comenzaron a aparecer, creí que solo sería pasajero y que solo era cuestión de tiempo para que solo quedaran miles de personas estafadas, sin embargo estoy en un grave error, porque no solo llegaron para quedarse sino que serán el futuro. Es de sabios cambiar de opinión. Comencemos por el principio ¿Qué es una criptomoneda? La criptomoneda o criptodivisa es un tipo de moneda digital que utiliza la criptografía para proporcionar un sistema de pagos seguro. Estas técnicas de cifrado sirven para regular la generación de unidades monetarias y verificar la transferencia de fondos. No necesitan de un banco central u otra institución que las controle. Aquí es donde yo tenía mis dudas. Explicar por qué. Regresando al tema. Las criptomonedas son un tipo de moneda digital, que son aquellas que no existen de forma física, pero que sirven como moneda de intercambio, permitiendo transacciones instantáneas a través de Internet y sin importar las fronteras. Otros tipos de moneda digital son las monedas virtuales (normalmente controlada por los desarrolladores), dinero electrónico y cupones de Internet. En el año 2009 apareció la primera criptomoneda completamente descentralizada, el Bitcoin, que fue creado por Satoshi Nakamoto junto con el software que lo sustenta (blockchain). A día de hoy no se sabe quién está detrás del nombre del creador. La aparición del bitcoin fue tan innovadora que los términos de criptomoneda y Bitcoin se funden en uno solo y es indistinto hablar de uno u otro. En nuestros días, han aparecido más criptomonedas basadas en la pionera Bitcoin, que se conocen como altcoin, algunas de ellas son Namecoin (2011), Litecoin (2011) o Peercoin (2012). Para comprender mejor las criptomonedas, regresemos en el tiempo. El Origen de las criptomonedas A través de la historia, ha habido múltiples medios de intercambio de bienes y servicios. Todos ellos han ido sufriendo evoluciones y cambios o, directamente, han desaparecido. Es el caso del trueque o la utilización de materiales preciosos, los cuales dejaron paso al sistema que hasta la actualidad ha funcionado, los billetes y monedas. No obstante, en una época donde la tecnología cada día gana más y más terreno, se hace necesario un medio de intercambio más ajustado a los tiempos: la criptomoneda. A raíz del movimiento cypherpunk en los años 80, surgió la criptomoneda. Este arte defendía el uso extendido de escribir con claves secretas que tan solo podría entender quien supiese descifrarlas. Una década después, David Chaun crea Digicash para proporcionar un sistema centralizado de dinero electrónico que permitía transacciones más seguras y anónimas. En el mismo período, Adam Black propone Hashcash, un sistema para controlar el spam y los ataques de denegación de servicio. Aunque no sería hasta el 2009 cuando surgió el Bitcoin, la primera criptomoneda completamente descentralizada. Las principales características de las criptomonedas son: Criptografía: Utilizan técnicas de cifrado para realizar cobros y pagos seguros. Descentralización: No necesitan ser controladas por ninguna institución. No hay posibilidad de falsificación o duplicación: Un sistema criptográfico protege a los usuarios. No hay intermediarios: Contacto directo persona a persona. Las transacciones son irreversibles: Una vez se efectúe el pago, no hay posibilidad de cancelación. Se pueden intercambiar por otras divisas. Privacidad de uso: No es necesario revelar tu identidad al hacer negocios. Veamos las ventajas y desventajas de estas: Ventajas Bajos costes de transacción, como consecuencia de la no presencia de intermediarios. Seguridad, pues cada moneda pertenece solo a su dueño. Transparencia, ya que las transacciones se incorporan en un registro de acceso libre. Se acumula en un espacio ínfimo como es un USB. Por su parte, las desventajas son: Volatilidad de sus precios. Falta de aceptación actual por algunas empresas. Al no necesitar un regulador como el Gobierno o el Banco Central y proporcionar privacidad pueden ser utilizadas para transacciones ilegales. Aunque conforme pasa el tiempo la criptomoneda gana confianza. Conclusión final ¿Son el futuro?. Sin más hasta aquí el episodio de hoy .......... Muchas gracias por escucharme y por estar del otro lado porque me motivan a seguir compartiendo mis consejos, que aplico en mi día a día. Si te pareció interesante, pero sobre todo que te aportó valor y puedes aplicarlo a tu negocio, por favor, házmelo saber con una valoración, comentario, siguiendome en cualquiera de las plataformas donde se puede escuchar Podcast. Esto me ayudará a que más personas puedan escucharme y tal vez sea lo que necesitan para hacer crecer su dinero, así que ayúdame a llegar a más personas. Son bien recibidos todos tus comentarios, sugerencias cualquier cosa que me quieras decir, en finanzasonline.com.mx Que Dios te bendiga, te envió un enorme apretón de manos, un gran Podabrazo ¡¡¡Que tengas un fascinante Martes!!!
We have very special episode this week featuring some of the godfathers of Bitcoin: Nick Szabo, Adam Back and David Chaum. This was recorded as a live panel from Seoul at Korea Blockchain Week and is laid out as a history of the ideas and events that led to Bitcoin from their first person accounts, plus their current thoughts on the experiment and what excites them about the future. From the cryptography and cypherpunk movements to David’s DigiCash, Adam’s Hashcash proof-of-work, Nick’s Bit Gold, and more. Their own contributions were foundational to the development of Bitcoin, and it was fascinating to have them together and playing off of each other in a discussion of that history. A special thanks for fact block for organizing.

Location: Skype Date: Thursday, 9th January Project: Bitcoin Magazine Role: Technical Editor Welcome to the Beginner's Guide to Bitcoin. Bitcoin can be intimidating for beginners. The protocol is complicated, the community can be aggressive and unforgiving, silly mistakes can lose you money, and it is easy to succumb to altcoin marketing. Bitcoin does though, offer you the opportunity to hold a new type of monetary asset, one which can't be seized by the government and is censorship resistance and It has the potential to change the way the world. The goal of What Bitcoin Did has always been about making things simple; there are no stupid questions, and the show is here to help beginners navigate this new world. To kick off 2020, we are launching a special series to help beginners understand Bitcoin. We will be looking at the basics from breaking down the protocol to explaining the economics and discussing the potential societal shift. Beginners Guide Part 3 - Aaron van Wirdum on Bitcoin's Pre-History and the Cypherpunks Founded by Eric Hughes, Tim May and John Gilmore the cypherpunks were a group of hackers, privacy enthusiasts and crypto-anarchists. The group consisted of some of the most prominent cryptographers including Phil Zimmermann, Adam Back, Nick Szabo and Hal Finney. The cypherpunks had its factions; some focussed on privacy tools, others on encryption and some on building decentralised monetary systems. It was on the cypherpunk mailing list and during their meetups that the building blocks of Bitcoin were born. On October 31st 2008, Satoshi Nakamoto emailed the cypherpunk mailing list, telling them "I've been working on a new electronic cash system that's fully peer-to-peer, with no trusted third party." In the 11 years that followed Bitcoin has proven to be the most successful attempt at creating a censorship-resistant and trust minimised digital currency. Each previous attempt at creating a form of digital money had solved parts of the puzzle, but Satoshi was able to put these pieces together along with his innovations to create Bitcoin. The previous attempts included: In the 1990's eCash, headed by David Chaum, attempted to make online payments anonymous. In 1997 Adam Back created HashCash, a proof-of-work system to reduce email spam and prevent denial of service attacks. In 1998 Wei Dai proposed B-money to allow for an "anonymous, distributed electronic cash system". Around the same time, Nick Szabo proposed Bit Gold where unforgettable proof of work chains would share properties of gold: scarce, valuable and trust minimised but with the benefit of being easily transactable. In 2004 Hal Finney built upon the idea of Hashcash and created Reusable Proofs of Work. When Satoshi released the Bitcoin whitepaper, rather than a revolution, Bitcoin was an evolution of all that had come before it with Bitcoin being the most trust minimised, censorship-resistant and hardest currency that has ever existed. In Part 3 of The Bitcoin Beginner's Guide, I talk to Aaron van Wirdum, a journalist and Technical Editor at Bitcoin Magazine. Aaron explains the cypherpunk movement and the digital money projects which paved the way for Bitcoin.

You can check out the back story of Dixon’s first company, SiteAdvisor, here. It was built during a time when spyware was a booming business and browsers had few systems in place to combat bad actors. The company was acquired by McAfee in 2006. It's a great trip through the history of web security at the time. Dixon next turned his attention to machine learning. He and his co-founders created Hunch, which worked to learn users’ tastes and recommend items they might enjoy. It was an early attempt to build the taste graph, a parallel to the social graph. It was acquired by eBay in 2011. Many of these techniques are now widely used across the biggest social networks in the world.Dixon then moved into the world of venture capital. You can read more about the Crypto Fund he helps to lead and the new startup school a16Zz is launching to help educate a new generation of programmers and founders. Application are still open.If you're interested in learning more about the background of Hashcash, which foreshadowed a lot of the ideas found in Bitcoin, there is some good info here.

Ben Mezrich’s newest blockbuster -- Bitcoin Billionaires: A True Story of Genius, Betrayal, and Redemption -- unfolds like a sequel to where The Social Network, based on his Accidental Billionaires, left off. This time, twins Cameron and Tyler Winklevoss segue from villains to protagonists as they’re introduced to cryptocurrencies and row along with digital assets as they flow from the dark web to the mainstream, becoming the first “Bitcoin Billionaires” along the way. In laying out the second act of Winklevii, Mezrich also delivers a Bitcoin primer for the common man, ripe for the silver screen.

Location: San Francisco Date: Monday, 21st October Project: n/a Role: Blockchain, cryptocurrency, and smart contracts pioneer On October 31st 2008, Satoshi Nakamoto emailed the cypherpunk mailing list, telling them "I've been working on a new electronic cash system that's fully peer-to-peer, with no trusted third party." In the 11 years that followed Bitcoin has proven to be the most successful attempt at creating a censorship-resistant and trust minimised digital currency. Bitcoin was not the first attempt at creating a trust minimised currency, and there were several proposals, implementations and technologies which led to Bitcoin: In the 1990's DigiCash, headed by David Chaum, attempted to make online payments anonymous. In 1997 Adam Back created HashCash using a proof-of-work system to reduce email spam and prevent denial of service attacks. In 1998 Wei Dai proposed B-money to allow for an "anonymous, distributed electronic cash system". In 2004 Hal Finney built upon the idea of Hashcash and created Reusable Proofs of Work. And in 2005 Nick Szabo proposed Bit Gold. Where unforgettable proof of work chains would share properties of gold: scarce, valuable and trust minimised but with the benefit of being easily transactable. When Satoshi released the Bitcoin whitepaper, rather than a revolution, Bitcoin was an evolution of all that had come before it with Bitcoin being the most trust minimised, censorship-resistant and hardest currency that has ever existed. Among Satoshi's email recipients was Nick Szabo, a computer scientist, cryptographer, the designer of Bit Gold and Smart Contracts pioneer. In a rare interview, Nick joins me to discuss the cypherpunk movement, what money is, privacy and of course, Bitcoin.

This year I had the great privilege of Emceeing Bitcoin 2019 in San Francisco, a fantastic conference with some incredible speakers. Adam Back and Scott Stornetta are two heavyweights who invented crucial technology at the heart of Bitcoin. Stornetta invented the early Blockchain, and Back invented HashCash with the Proof-of-work system. I set up an interview with the two of them for my channel to talk about their involvement in helping make Bitcoin possible. I was delighted that Bitcoin 2019 allowed me to host this conversation on the mainstage at the event. It was an honor to be a part of this discussion! Video: https://youtu.be/6wLi7y_GQGs
In this episode I spend some time with Adam Back Cypherpunk, Applied Cryptographer, Inventor of Hashcash, Cofounder and CEO of Blockstream.

众说区块链基础篇之比特币的故事（语音版） 大家好，欢迎收听由区块链第一媒体联盟、区块链第一商学院共同打造的《众说区块链之基础篇》。我是区块链第一媒体联盟发起单位——链团财经的发行负责人喵团,今天我们讲一讲比特币的故事。比特币的起源和发展2008年，一位化名为中本聪的人，在一篇为《比特币：一个点对点的电子现金系统》的论文中首先提出了比特币。他结合以前的多个数字货币发明，如B-money和HashCash，创建了一个完全去中心化的电子现金系统，不依赖于通货保障或是结算验证保障的中央权威。关键的创新是利用分布式计算系统（称为”工作量证明”算法）每隔10分钟进行一次的全网”选拔”,能够使用去中心化的网络同步交易记录。这个能优雅的解决双重支付问题（即一个单一的货币单位可以使用两次，此前，双重支付问题是数字货币的一个弱点，并通过一个中央结算机构清除所有交易来处理）。比特币最早是一种网络虚拟货币，可以购买现实生活当中的物品。它的特点是分散化、匿名、只能在数字世界使用，不属于任何国家和金融机构，并且不受地域的限制，可以在世界上的任何地方兑换它，也因此被部分不法分子当做洗钱工具。2013年，美国政府承认比特币的合法地位，使得比特币价格大涨。而在中国，2013年11月19日，一个比特币就相当于6,989元人民币。2014年1月7日，淘宝发布公告，宣布1月14日起禁售比特币、莱特币等互联网虚拟币等商品。西维吉尼亚州民主党参议员乔·曼钦（Joe Manchin）2014年2月26日向美国联邦政府多个监管部门发出公开信，希望有关机构能够就比特币鼓励非法活动和扰乱金融秩序的现状予以重视，并要求能尽快采取行动，以全面封杀该电子货币。2017年1月11日），中国人民银行上海总部、上海市金融办等对比特币中国开展现场检查，重点检查该企业是否未经许可或无牌照开展信贷、支付、汇兑等相关业务；反洗钱制度落实情况；资金安全隐患等。2017年1月12日，央行营业管理部也在北京进驻“火币网”、“币行”等交易平台。 那我们再聊聊比特币的优势有什么呢1. 完全去处中心化，没有发行机构，也就不可能操纵发行数量。其发行与流通，是通过开源的p2p算法实现。2. 匿名、免税、免监管。3. 健壮性。比特币完全依赖p2p网络，无发行中心，所以外部无法关闭它。比特币价格可能波动、崩盘，多国政府可能宣布它非法，但比特币和比特币庞大的p2p网络不会消失。4. 无国界、跨境。跨国汇款，会经过层层外汇管制机构，而且交易记录会被多方记录在案。但如果用比特币交易，直接输入数字地址，点一下鼠标，等待p2p网络确认交易后，大量资金就过去了。不经过任何管控机构，也不会留下任何跨境交易记录。5. 山寨者难于生存。由于比特币算法是完全开源的，谁都可以下载到源码，修改些参数，重新编译下，就能创造一种新的p2p货币。但这些山寨货币很脆弱，极易遭到51%攻击。任何个人或组织，只要控制一种p2p货币网络51%的运算能力，就可以随意操纵交易、币值，这会对p2p货币构成毁灭性打击。很多山寨币，就是死在了这一环节上。而比特币网络已经足够健壮，想要控制比特币网络51%的运算力，所需要的cpu/gpu数量将是一个天文数字。 而且，区块链技术是比特币原创的核心技术。在比特币被发明之前世界上并不存在区块链这个东西。比特币发明之后，很多人参考比特币中的区块链实现，使用类似的技术实现各种应用，这类技术统称区块链技术。用区块链技术实现的各种链即为区块链。所以说是比特币打开了区块链大门。这样您应该理解了比特币和区块链的关系了吧。以上是和您分享的全部内容。内容出品：链团财经，您可以在微信订阅号、喜马拉雅上搜索链团财经就能找到我们哦！感谢您对区块链第一媒体联盟及区块链第一商学院的支持。

Please subscribe to listen in on future deep-dives. Next week: Attack of the 51% hash monster! Episode 4: Hey, I’m Not Lazy...I Even Have Proof of Work! What is Proof of Work? PoW is a protocol, or accountability system, that deters service abuses like denial of service attacks and spam. Hashcash is an early version of this technology, and is used in email systems, blogs, and other digital networks to deter spam attacks. In blockchain systems, the technology is inverted. The Proof of Work hash protocol is used as an enabling device to allow decentralized participants to transparently append blocks of transactions to an existing chain of prior transactions. The Bitcoin blockchain network, the first functioning “chain of blocks” as it is called in Satoshi’s whitepaper, employs a hash-based Proof of Work concept. What is a hash? Hashing functions take an input and produce an output. They are digital code that represent transactions, or a set of transactions contained in an information “block”, which is recorded on a blockchain. A blockchain is simply a digital, open, immutable ledger of transactions. Algorithms are used to make hashes from inputs, or transactions that would like to be attached to the open ledger, or blockchain. Imagine you have a dialogue box, and in it you can record all the details of the transaction that you would like to be recorded on the blockchain, literally anything that you can type on a computer. Once you finish inputting the transaction details into the dialogue box of the algorithm program, which in bitcoin’s case is SHA-256, the algorithm calculates a hash from the input. What’s magical about math is that the same input will give the same output every time. But a change in the input will result in a new randomized, yet consistent, hash as an output. The output is always a specific length, and consistently so. Isn’t math wonderful? Why talk about hashes? The SHA-256 algorithm serves as a security measure and optimization tool. The blocks in a blockchain are “hashed”, or encoded into a series of numbers and letters. The use of hashing means that anyone dealing with a blockchain must remember the hash and not the input itself. In addition, each block will contain the hash of the previous block header, so that it maintains its place in the sequence of transactions recorded on the blockchain. Mining Decoding and encoding the blockchain is called mining, an essential part of the decentralized system of accountability that makes blockchains so unique and valuable. Mining involves computers running hashing algorithms to process the most recent block, with the information needed in mining or decoding being found in the information block's header. The cryptocurrency network sets a target value for this hash – the target hash – and miners try to determine this value by testing out all possible values. Here is where the economics comes in. The Bitcoin system rewards miners for their part in the distributed accountability network by providing cryptocurrency to the owner of the GPUs that successfully guess, or verify, the hash code. In other words, mining Bitcoin describes the process that a computer undertakes to confirm the pseudonymous transactions on the Bitcoin blockchain that is rewarded by the blockchain network’s cryptocurrency. In short, this protocol is called Proof of Work. When a Bitcoin miner is able to successfully confirm a hash (essentially a guessing game process), the Bitcoin system rewards the miner with digital cryptocurrency, 12.5 Bitcoins to be exact. At least until the next time the reward mechanism is halved in May 2020. And we'll see you...on the moon!

Interview location: LondonInterview date: Friday 9th Nov, 2018Company: BlockstreamRole: CEOThe Bitcoin whitepaper has eight references for eight projects and technologies which enabled and inspired Satoshi Nakamoto to create Bitcoin. One of those references is for Adam Back’s Hashcash, a proof-of-work email anti-spam tool.Adam’s credentials as an early Bitcoiner are second to none. Not only is he cited in the whitepaper but his contributions to the early discussions around the development of the protocol are documented at the Nakamoto Institute.Adam is now CEO of Blockstream, a leading developer of Bitcoin technologies. From sidechains to Lightning to their satellite network, Blockstream building out the commercial infrastructure to take Bitcoin to every corner of the earth.In this interview, Adam reflects on a decade of Bitcoin with me, comparing and contrasting the early days of with now and explains to me why the whitepaper was different from previous attempts at digital cash. We also discuss the launch of liquid, how sidechains work and what is coming up for Blockstream.-----If you enjoy The What Bitcoin Did Podcast you can help support the show my doing the following:Become a Patron and get access to shows early or help contributeMake a tip:Bitcoin: 3FiC6w7eb3dkcaNHMAnj39ANTAkv8Ufi2SQR Codes: Bitcoin | Ethereum | Litecoin | Monero | ZCash | RipplecoinIf you do send a tip then please email me so that I can say thank youSubscribe on iTunes | Spotify | Stitcher | SoundCloud | YouTube | TuneIn | RSS FeedLeave a review on iTunesShare the show and episodes with your friends and familySubscribe to the newsletter on my websiteFollow me on Twitter Personal | Twitter Podcast | Instagram | Medium | YouTubeIf you are interested in sponsoring the show, you can read more about that here or please feel free to drop me an email to discuss options.
