  In blockchain, bribery is an inevitable problem since users with various
goals can bribe miners by transferring cryptoassets. To alleviate the negative
effects of such collusion, Ethereum blockchain implemented new transaction fee
mechanism in the London Fork, which was deployed on August 5th, 2021. In this
paper, we first filter potential bribery by scanning Ethereum transactions, and
the potential bribers and bribees are centralized in a small group. Then we
construct bribing proxies to measure the active level of bribery and then
investigate the effects of bribery. Consequently, bribery can influence both
Ethereum and other mainstream blockchains, in aspects of underlying
cryptocurrency, transaction statistics, and network adoption. Moreover, the
London Fork shows complicated effects on relationship between bribery and
blockchain factors. Besides, bribery in Ethereum relates to stock markets,
e.g., S&P 500 and Nasdaq, implying implicit interlinks between blockchain and
traditional finance.
