This synchronous nature of the blockchain limits the entrance of transactions into the network because of the previously mentioned throughput limit. Therefore, every node on the entire network must first receive the latest valid block before being able to validate any other transactions on the network. For a Bitcoin node to validate a block that contains a transaction, it must first ensure the block has a reference the block immediately before it. Synchronous OrderĪll transactions are timestamped and in chronological order. It also limits the throughput of confirmed transactions onto the Bitcoin network, allowing for approximately 7 transactions every seconds at most. This limited space acts as a security parameter against network attacks. This is to incentivize mining due to the limited space in each Bitcoin block. The blockchain model inherently introduces a transaction fee market. However, there are two fundamental problems posed here that IOTA aims to tackle: Transaction fees This infrastructure has proven to be functional, secure, and potentially scalable over the last ten years. This maintains the perfect chronological order of all transactions. It is then published to the network, with a direct reference to the previously timestamped block. Miners then validate them by bundling them into a timestamped block. A limited number of these transactions with the highest fees attached to them in the pool are selected from the pool by miners. They are pooled together in a pool called the memory pool (mempool). In the Bitcoin blockchain, transactions are sent out by users. To understand IOTA it’s helpful to first make sure you understand Bitcoin, and specifically how Bitcoin mining and validation works: A visualization of how Bitcoin blocks are chained, source: Bitcoin Whitepaper These can be infinitely small amounts between a large a number of devices. By removing the use of a traditional blockchain and a transaction fee system, it enables the ability to conduct many transactions.
IOTA is the world’s first cryptocurrency that operates entirely without a blockchain and transaction fees. IOTA aims to revolutionize the microtransaction, and in particular, the Internet of Things industry.
