Ethereum emerged as a more experimental technology since it is difficult to make\u00a0<strong>disruptive changes<\/strong>\u00a0in Bitcoin. The idea behind Ethereum was to create a kind of\u00a0<strong>global computer<\/strong>\u00a0that could execute complex contracts, the so called\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-a-smart-contract\/\">smart contracts<\/a>.

These blockchains are characterized by the use of a new consensus system called\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-proof-of-stake-and-how-does-it-work\/\">Proof of Stake<\/a>. Examples of this generation are\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-polkadot-dot\/\">Polkadot<\/a>,\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/all-about-solana-sol\/\">Solana<\/a>,\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/all-about-cardano-ada\/\">Cardano<\/a>\u00a0and even\u00a0<strong>Ethereum 2.0<\/strong>\u00a0itself.

But first, it is worth noting that the latest generation coins do not imply that they are better or worse than the first ones. In the world of blockchains there are no magic solutions and every\u00a0<strong>feature has a negative counterpart<\/strong>. The key is to ask: \u201cWhat feature does this coin optimize, and at the cost of what?\u201d. For example, Bitcoin\u00a0<strong>optimizes<\/strong>\u00a0security and that is why its language is more limited than that of other platforms such as Ethereum.<\/p>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div id=\"image_1674314604\" class=\"img has-hover x md-x lg-x y md-y lg-y\">\n<div class=\"img-inner dark\"><img fetchpriority=\"high\" decoding=\"async\" class=\"attachment-large size-large lazyloaded\" src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/06\/Simbolo-de-Stacks-Simbolo-de-Bitcoin1.jpg\" sizes=\"(max-width: 768px) 100vw, 768px\" srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/06\/Simbolo-de-Stacks-Simbolo-de-Bitcoin1.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/06\/Simbolo-de-Stacks-Simbolo-de-Bitcoin1-300x205.jpg 300w\" alt=\"\u00bfQu\u00e9 es Stacks?

This is a prerequisite for creating decentralized money, there can be no\u00a0<strong>points of failure<\/strong>\u00a0such as a bank or financial institution.<\/p>\n<p>The difficulty in creating decentralized digital money is that you need this entire network to agree on how many coins each direction has.

On the other computers he can say he has 10 coins, and on his computer he has 100 coins.<\/p>\n<p>If there is no consensus on how many coins everyone has, you can\u2019t use it as money because you can\u2019t trust anyone.

In the PoW, the miners are the ones who update the balances of each user (<strong>processing transactions<\/strong>). The\u00a0<strong>miners<\/strong>\u00a0perform\u00a0<strong>computational calculations<\/strong>\u00a0(<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-sha-256-algorithm-and-how-does-it-work\/\">SHA-256<\/a>) until they come up with a<strong>\u00a0solution<\/strong>\u00a0and in doing so they have \u201cburied\u201d those transactions under computation (we will explain this in a few moments).<\/p>\n<p>Transactions are processed in batches (the so called\u00a0<strong>blocks<\/strong>) and each one generates a\u00a0<strong>reward<\/strong>\u00a0for the miner. Moreover, the only valid version of how much money each user has is the one with the\u00a0<strong>most computatio<\/strong>n behind it.<\/p>\n<p>This design hides an overwhelming logic, it is so genius that many consider it<strong>\u00a0the greatest innovation<\/strong>\u00a0of our century. What Satoshi is doing is simply saying: \u201cprocessing transactions has a cost, if you want to recover that cost and generate a profit you have to be honest\u201d. As long as we humans don\u2019t like to lose money,\u00a0<strong>this incentive system<\/strong>\u00a0will work.<\/p>\n<p>In other words, the<strong>\u00a0blockchain<\/strong>\u00a0is just a\u00a0<strong>record of transactions<\/strong>\u00a0(where we can see how much money each address has). And under this PoW model, that register is immutable. It is\u00a0<strong>immutable<\/strong>\u00a0not because it cannot be modified, but because\u00a0<strong>the cost of modifying<\/strong>\u00a0the register is\u00a0<strong>greater than the benefits<\/strong>. On the contrary, acting honestly does\u00a0<strong>generate profit<\/strong>\u00a0(processing new transactions, or in other words,\u00a0<strong>mining new blocks<\/strong>).<\/p>\n<p>That\u2019s why I say that transactions \u201cget buried under computation\u201d, because if you want to remove them from the log (undo transactions) you will have to do all\u00a0<strong>the accumulated computation<\/strong>\u00a0on them again, which will also be\u00a0<strong>bigger and bigger<\/strong>\u00a0because other miners keep adding more and more blocks (with their proofs of work).<\/p>\n<p>In this example it will be seen better: imagine that I make a transaction paying for a car. That transaction is included, for example, in block 10. In a few minutes, on block 10 block 11 is mined, so my transaction is buried under the computation of block 10 and 11. And so it is deeper and deeper in the blockchain (hence it is called blockchain). Once I have the car, to undo the transaction and get my money back (steal it) I have to redo that accumulated computation, something neither feasible nor profitable. In this system you can trust that\u00a0<strong>nobody will cheat because cheating is not profitable<\/strong>.<\/p>\n<p>Since modifying the registry is economically unfeasible, it is also unfeasible to reverse transactions. And furthermore, miners cannot censor transactions because these\u00a0<strong>pay commissions<\/strong>\u00a0and, in principle, the people involved in the transaction are\u00a0<strong>pseudonymous<\/strong>. This entire network agrees on how much money each address has because\u00a0<strong>the only valid blockchain is the one with the most computation.<\/strong><\/p>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<h2><span class=\"ez-toc-section\" id=\"consensus_rules\"><\/span>Consensus rules<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div class=\"is-divider divider clearfix\"><\/div>\n<p>The consensus is not only on what\u00a0<strong>the official blockchain<\/strong>\u00a0is, but also on what type of\u00a0<strong>transactions are valid<\/strong>, how many coins can be generated (<strong>inflation<\/strong>), how the\u00a0<strong>blocks<\/strong>\u00a0should be built, etc.<\/p>\n<p><strong>Anything that is incorrect is rejected by the network<\/strong>\u00a0and these rules can be updated, either compatibly (<strong>Soft Fork<\/strong>) or incompatibly (<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-a-hard-fork\/\">Hard Fork<\/a>) with the previous rules.
