This new research provides a way to overcome this limitation.
In recent years, the field of spintronics has emerged as a promising frontier in the world of electronics. This revolutionary approach to technology moves beyond the traditional reliance on electron charge to leverage the intrinsic spin of electrons for data storage and processing. Spintronics offers the tantalizing prospect of creating devices that are not only […]

Opinion by: Dr. Michael Tabone, senior economist for CointelegraphBitcoin (BTC) has long been hailed as unbreakable and untouchable, a digital stronghold against the forces of change. Bitcoin’s bedrock of security is facing its first true test with quantum computing, which should be addressed sooner rather than later. Its cryptographic armor will crack if not addressed, forcing the network to adapt or perish. Bitcoin’s node count is growing, but incentives are still absentBitcoin’s full node network has grown over time, a sign of increasing adoption and a more robust infrastructure, but the core issue remains. The voluntary act of running a node still has no financial incentive. Miners earn rewards for securing the network, yet full node operators get nothing for their role in keeping Bitcoin decentralized. At the same time, a significant portion of these nodes are run by exchanges, custodians and large mining pools. These
