Blockchain has firmly entered the life of the modern internet, but there are other promising technologies that may compete with it. One such alternative is **Tangle** from IOTA, which uses a data structure in the form of a directed acyclic graph (DAG), allowing for the elimination of mining and reducing transaction costs. **Hashgraph** is also based on DAG, but its consensus algorithm increases speed and security.
Meanwhile, **Hedera** uses a hashgraph with an improved architecture, providing much higher throughput compared to traditional blockchain networks. These technologies promise to solve scalability and energy consumption issues faced by classic blockchains.
In addition, it is important to note the development of the **Cryptocurrency Asset Security Protocol** (P2P) and **multi-chain platforms**, such as Polkadot, which unite different networks, allowing data and assets to be exchanged between different systems without blockchain.
Understanding these alternatives is crucial not only for developers but also for investors focusing on sustainable and scalable technologies in the cryptocurrency industry.
