Cryptocurrencies recently are getting more popular, globally, and have a huge market value which is more than many reputed companies. Cryptocurrencies are just like digital assets which can be transferred between parties. There are various protocols that govern the working of cryptocurrencies, and it uses blockchain the underlying technology, to secure the transactions. It uses digital signatures to authenticate transactions. There are many digital signature schemes with each of them offering different advantages and disadvantages, the main algorithms or protocols are the consensus algorithm and the digital signature scheme. In this paper, we have shown a hybrid method to gain a few advantages over existing protocols of cryptocurrencies. We show how schnorr digital signatures are better than the ESCDA digital signature. We have proposed modifications to the proof of work consensus protocol to reduce the time and energy consumed in the mining process of the blocks.
