Detective Mining: Selfish Mining Becomes Unrealistic under Mining Pool Environment
blockchain Bitcoin, security
2019/5/21
One of Bitcoin’s core security guarantees is that, for an attacker to be able to successfully interfere with the Bitcoin network and reverse transactions, they need to control 51% of total hash power....
Uncle Traps: Harvesting Rewards in a Queue-based Ethereum Mining Pool
queue-based mining pools ethereum uncle blocks
2019/1/26
Mining pools in Proof-of-Work cryptocurrencies allow miners to pool their computational resources as a means of reducing payout variance. In Ethereum, uncle blocks are valid Proof-of-Work solutions wh...
Bitcoin, the first successful cryptocurrency, uses the blockchain structure and PoW mechanism to generate blocks. PoW makes an adversary difficult to control the network until she retains over 50\% of...
