Currently, Kadena has raised more than\u00a0<strong>$15 million<\/strong>. Most of this sum of money has been raised in the form of SAFT (Simple Agreement for Future Tokens). To this total we can add the grant of about\u00a0<strong>$150,000 that Kadena received from the Interchain Foundation.<\/strong>\u00a0This foundation is the development team behind the\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-cosmos-atom-the-key-to-interoperability\/\">Cosmos<\/a>\u00a0network. The\u00a0<strong>$150,000<\/strong>\u00a0was acquired to build a version of Pact that was compatible with the\u00a0<strong>Tendermint<\/strong>\u00a0protocol.<\/p>\n<p>Two private token sales were conducted at Kadena in early 2018. Those sales were in the form of a Simple Agreement for Futures Tokens (SAFT). The first sale was closed in\u00a0<strong>January 2018<\/strong>\u00a0for a total of $2.25 million through the unloading of 4.5 million\u00a0<strong>KDA<\/strong>\u00a0tokens which at the time were worth $0.5 each token. The second sale was held in April 2018 and raised another $12.9 million through the sale of\u00a0<strong>17.2 million<\/strong>\u00a0coins which at the time was worth approximately $0.75 each token.<\/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_21579619\" 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\/12\/Kadena2.jpg\" sizes=\"(max-width: 768px) 100vw, 768px\" srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/12\/Kadena2.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/12\/Kadena2-300x205.jpg 300w\" alt=\"Kadena2\" width=\"768\" height=\"526\" data-srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/12\/Kadena2.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/12\/Kadena2-300x205.jpg 300w\" data-src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2021\/12\/Kadena2.jpg\" data-sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/div>\n<\/div>\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=\"how_does_kadena_work\"><\/span><strong>How does Kadena work?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The main objective of the Kadena project focuses on\u00a0<strong>optimizing scalability.<\/strong>\u00a0In addition, Kadena features a new\u00a0<strong>smart contract<\/strong>\u00a0language known as Pact.\u00a0<strong>Pact<\/strong>\u00a0is equipped with formal verification and updatable smart contracts.<\/p>\n<p>Although we will go into more detail on how it works later, we should know that it employs a new type of\u00a0<strong>Proof-of-Work (PoW)<\/strong>\u00a0consensus mechanism. Its mechanism is called\u00a0<strong>Chainweb.<\/strong>\u00a0This mechanism allows multiple individually mined blockchains to work in parallel in order to\u00a0<strong>execute network transactions<\/strong>. Thanks to this new design,\u00a0<strong>high transaction<\/strong>\u00a0throughput is enabled at the base layer without the need to implement new scalability or functionality solutions at the\u00a0<strong>second layer.<\/strong><\/p>\n<p>The entire operation of the project is geared towards\u00a0<strong>optimizing its base layer<\/strong>\u00a0for transaction performance and achieving greater developer adoption\u00a0<strong>without implementing second-layer functionality or scalability solutions.<\/strong><\/p>\n<p>According to its team of developers, Kadena, based on its internal testing does not have any transaction limits per second.\u00a0<strong>This is due to Kadena\u2019s native smart contract language, Pact<\/strong>. This language makes it possible to ameliorate common flaws observed in Ethereum\u2019s Solidity, most notably the language\u2019s susceptibility to infinite loops and lack of formal verification.<\/p>\n<p>Another feature of Pact is that its smart contracts\u00a0<strong>can be updated at a moment\u2019s<\/strong>\u00a0notice without the need for a\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-a-hard-fork\/\">hard fork<\/a>.

In this operation, each individual chain has the same<strong>\u00a0capabilities<\/strong>\u00a0as the main chain.<\/p>\n<p>&nbsp;<\/p>\n<p>The Chainweb was designed with the sole objective of streamlining transactions in a linear fashion while adding new parallel chains to the main network. On the miner side, miners are directed to each chain individually\u00a0<strong>reducing the typical \u201cbottleneck\u201d<\/strong>\u00a0that we usually find in currencies such as Bitcoin.<\/p>\n<p>&nbsp;<\/p>\n<p>Regarding the security of the system, the chains have a hash of\u00a0<strong>Merkle roots<\/strong>\u00a0that can be found in the sister chains. The chains are responsible for\u00a0<strong>inspecting<\/strong>\u00a0the roots to check that the branches do not stray from each other.\u00a0<strong>This ensures<\/strong>\u00a0<strong>that the chains get a single view of the transaction history of all the chains.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>In addition to all of the above, Kadena has a new unique feature that defines additional security. This feature is based on the fact that security is defined by the\u00a0<strong>Merkle Cone<\/strong>\u00a0of a given block.\u00a0<strong>These cones define which past transactions are provable and which are not<\/strong>. The Merkle Cone defines<strong>\u00a0the total amount of work required<\/strong>\u00a0to replace a past block or duplicate a past transaction.<\/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=\"what_is_the_kda_token\"><\/span><strong>What is the KDA token?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>KDA is the\u00a0<strong>native token<\/strong>\u00a0of the Kadena platform.
