This may be the Billion dollar question experts and tech enthusiasts are still trying to answer.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">Blockchain has been around for a while now and no other DTL seemed to be good enough to fully replace the system that became famous with the Bitcoin.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">Ethereum\u2019s network is the one that came the closest to taking over the digital world. Even with improvements, its blockchain still faces the problem of scalability, although no one managed to grow a network larger than the Ethereum one.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">However, in the past few years, some cryptocurrencies have been exploring other types of systems and building brand new non-blockchain solutions. Among them, there\u2019s two that seems very promising: DAG and Hashgraph.<\/span><\/p>\n<p><span style=\"font-size: 24px; font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\"><strong>Dag vs Blockchain vs Hashgraph<\/strong><\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">The non-blockchain systems emerged as a way to solve two big problems of a blockchain network:<\/span><\/p>\n<ul>\n<li><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">Consensus-based method<\/span><\/li>\n<li><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">Scalability <\/span><\/li>\n<\/ul>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">In short, blockchain systems can validate a transaction using two forms of consensus &#8211; Proof of Work (PoW) or Proof of Stake (PoS). Although both are efficient and trustworthy, the first one requires a big amount of energy to be carried out.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">The second one was built to be less energy consuming and make the consensus fairer among the miners. PoS also helps leverage the transition speed, but can\u2019t solve the scalability issue.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">In a blockchain network, only one block can be created at a time and the scalability is tied to the number of blocks that can be added per second in the chain and the number of transactions a given block can contain.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">With the \u2018blockless\u2019 network, in theory, these problems are solved.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">Developed in 2016, <span style=\"color: #ff6600;\"><a style=\"color: #ff6600;\" href=\"https:\/\/www.blockchainappfactory.com\/hashgraph-development\"><strong>Hashgraph<\/strong><\/a> <\/span>got famous for its Gossip Protocol. Just as the name suggests, the consensus is made through some gossip, once a computer (the nodes in a blockchain network) executes a transaction, it informs two other computers randomly and they will also transfer the message to two more computers <\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">Due to the lack of blocks, the transactions happen faster and cheaper, because there are no miners and no need to link large blocks on after another.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">In the DAG-based network, miners are also extinct and the users become the validators. To be able to perform one transaction, the users have to validate two old transactions.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">Dag stands for <strong><span style=\"color: #ff6600;\"><a style=\"color: #ff6600;\" href=\"https:\/\/www.blockchainappfactory.com\/directed-acyclic-graph\">Directed Acyclic Graph<\/a><\/span><\/strong>, a mathematical and computer science term that refers to an acyclic graphic. To make it simple, all the links made between nodes go in just one direction.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">In the blockchain, a block always refers to all the blocks created before and the one that comes after itself, creating a cycle. But in the DAG, a node can only contain information about two older transactions and can never refer to itself in any path.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">This also helps to make transactions faster, since there\u2019s no need to wait for a block to be completed and validated.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">Although both systems seem like a great opportunity to solve the blockchain scalability issue, none of them managed to beat the size of the Ethereum <strong><span style=\"color: #ff6600;\"><a style=\"color: #ff6600;\" href=\"https:\/\/www.blockchainappfactory.com\/blockchain-development-company\">blockchain network<\/a><\/span><\/strong>.<\/span><\/p>\n<p><span style=\"font-family: 'trebuchet ms', geneva, sans-serif; color: #000000;\">So, as we can see, replacing the blockchain network has been proven to be a tough task, and we still don\u2019t have a viable and tangible alternative for the Distributed Ledger Technology.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; What is the future of Distributed Ledger Technology (DLT)?
