yet no common framework or consensus has emerged for AI agent security. This lack of standardization reflects the complexity and range of existing vulnerabilities. Before introducing the additional risks of integrating with blockchain, it is essential to get an overview of the baseline ...
MostBitcoininvestors get very excited about the Bitcoin halving, which happens approximately every four years. When aBitcoin halvinghappens, the Bitcoin block reward decreases by half. The block reward is received by the miner that adds the next block to the Bitcoin blockchain, and it is the on...
