There are <span hours left until the#Dencunupdate of the#Ethereumnetwork begins. The change will have an impact on reducing the cost of transaction fees on ethereum 2nd layer networks to almost zero according to research by the renowned Fidelity Digital Assets, a company involved with blockchain since 2014 and serving hundreds of institutions around the world interested in building in the crypto market. The update tends to be felt in the user's practice (and in the pocket) over the next few months, however, the increase in new network demand (tx/s) may offset the reduction in cost. In other words: it may reflect more on long-term fundamentals than on the price paid for using the network in the short term. What to expect in the short term, then? If the expected short reduction of ~40x is faster than the new demand and the user sees an advantage in using L2 in relation to networks like #Solana, it will positively impact the price of ethereum because larger long-term investors gain by providing liquidity for short speculation investors/staking term, but if the opposite happens and the impact on prices is less than the new search for use by users, tokens from more centralized networks “ethereum killers” gain speculative importance. In the long term, the thesis of centralized and decentralized dapps in L2 ethereum remains stronger than that of feature blockchains, in the short term, not so much. Experimental projects may prefer to build on supporting EVM compatible networks such as Solana so as not to waste time and continue waiting for cost reductions on the Ethereum network to develop. Remembering that the update impacts more on users than on developers, who depend on the network cost of the mainnet, different from the user who chooses to directly use layer 2.
