BlockDAG (BDAG) has emerged as a top crypto project for 2025, raising $430 million in its presale. The Layer 1 blockchain integrates Bitcoin's Proof-of-Work security with a Directed Acyclic Graph (DAG) structure, achieving 1,400 transactions per second in its live testnet. Over 27 billion BDAG coins have been sold at a TGE price of $0.0015, with an anticipated mainnet price of $0.05. The project is supported by audits from CertiK and Halborn and a partnership with the BWT Alpine Formula 1® Team. Other notable projects for 2025 include SEI, Algorand, and Arbitrum, each focusing on addressing blockchain challenges such as scalability, DeFi integration, and Ethereum scaling.
