Blockchain / Bitcoin

Ya he tratado el tema de las cryptomonedas por encima alguna vez, pero parece que el «mundo digital» está casi listo para que abandonemos el «mundo analógico», por lo que una nueva moneda, no su concepto sino su concepción, está a la vuelta de la esquina; blockchain es el protocolo sobre el que se asienta esta revolución tecnológica, no sólo para el dinero; también para contratos y aplicaciones diversas (científicas, culturales, sanitarias…)

Key properties of bitcoin

  • Limited Supply – There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary as coins are only lost over time.
  • Open source – Bitcoin code is fully auditable. You can read the source code yourself here.
  • Accountable – The public ledger is transparent, all transactions are seen by everyone.
  • Decentralized – Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can’t be shut down similar to how Bittorrent works.
  • Censorship resistant – No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
  • Push system – There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
  • Low fee – Transactions cost a few cents, most wallets calculate this automatically but you can view current fees here.
  • Borderless – No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
  • Trustless – Bitcoin solved the Byzantine’s Generals Problem which means nobody needs to trust anybody for it to work.
  • Pseudonymous – No need to expose personal information when purchasing with cash or transacting.
  • Secure – Encrypted cryptographically and can’t be confiscated with proper key management such as hardware wallets.
  • Nearly instant – From a few seconds to a few minutes depending on need for confirmations.
  • Peer-to-peer – No intermediaries with a cut, no need for trusted third parties.
  • Portable – Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply remembering a string of words for wallet recovery.
  • Scalable – Each bitcoin is divisible down to 8 decimals allowing it to grow in value while still accommodating micro-transactions.
  • Designed Money – Bitcoin was created to fit all the fundamental properties of money better than gold or fiat


Por motivos evidentes, (padezco de moneditis), aquí me centro en la aplicación monetaria de blockchain …pero no deberíamos olvidar nunca lo analógico, por su sencillez, inmediatez…por si acaso.


Las analogías entre bitcoin y metales preciosos, además de las detalladas en la tabla superior, os las dejo a vosotros como deberes/tarea de casa 😉

ps Hay bastante información en la red sobre blockchain e innumerables cryptomonedas. Imposible resumir aquí esa avalancha de datos.
