Question: I need a blockchain solution that can provide fast transaction confirmation and high performance, what are my options?

If you're looking for a blockchain solution with fast transaction confirmation and high performance, Taraxa is a top contender. It's EVM compatible, which means it's easy to deploy Ethereum dApps, and it uses t-Graph consensus and blockDAG technology for a throughput of up to 5,000 transactions per second. That means transactions are confirmed almost immediately, with a block time of less than a second. Taraxa also places a priority on decentralization and cost-effectiveness, so it's a strong contender.

Another contender is aelf, a high-performance blockchain designed for scalable infrastructure and cross-chain interactions. It's got a multi-sidechain architecture and AI-boosted processing for a throughput of up to 35,000 transactions per second. aelf's modular, cloud-native design is designed to be highly secure and efficient, so it's a good choice for developers who want a scalable foundation for their dApps.

For high availability and performance, RPC Fast offers a blockchain node infrastructure with JSON-RPC endpoints for Ethereum, BNB Chain and Polygon. It's got predictive autoscaling, AI-based auto-scaling and self-healing nodes to ensure peak uptime and response times of less than 4 ms. That makes it a good choice for developers who need fast and reliable access to blockchain data.

And QuickNode offers a foundation for building decentralized products with high-reliability and security. It offers RPC & REST APIs for low-latency access to big blockchains, IPFS storage and rollups. With its focus on scalability and reliability, QuickNode can handle a lot of API requests, so it's a good choice for enterprise-scale apps.
