On April 15, a Berlin hardfork took place on the Ethereum mainnet at block #12 244 000. In anticipation of the event, the price of the asset renewed its all-time high above $2 460, and open interest in futures reached a record $8.1 billion.
Berlin has implemented four proposals for improving Ethereum, including a change in the gas price calculation algorithm (EIP-2565 and EIP-2929), as well as new types of transactions (EIP-2930 and EIP-2718).
