## Drawbacks of dapp development {#drawbacks-of-dapp-development}

- **Maintenance** – Dapps can be harder to maintain because the code and data published to the blockchain are harder to modify. It’s hard for developers to make updates to their dapps (or the underlying data stored by a dapp) once they are deployed, even if bugs or security risks are identified in an old version.
- **Performance overhead** – There is a huge performance overhead, and scaling is really hard. To achieve the level of security, integrity, transparency, and reliability that Ethereum aspires to, every node runs and stores every transaction. On top of this, proof-of-work takes time as well. A back-of-the-envelope calculation puts the overhead at something like 1,000,000x that of standard computation currently.
- **Performance overhead** – There is a huge performance overhead, and scaling is really hard. To achieve the level of security, integrity, transparency, and reliability that Ethereum aspires to, every node runs and stores every transaction. On top of this, proof-of-stake consensus takes time as well.
- **Network congestion** – When one dapp uses too many computational resources, the entire network gets backed up. Currently, the network can only process about 10-15 transactions per second; if transactions are being sent in faster than this, the pool of unconfirmed transactions can quickly balloon.
- **User experience** – It may be harder to engineer user-friendly experiences because the average end-user might find it too difficult to set up a tool stack necessary to interact with the blockchain in a truly secure fashion.
- **Centralization** – User-friendly and developer-friendly solutions built on top of the base layer of Ethereum might end up looking like centralized services anyways. For example, such services may store keys or other sensitive information server-side, serve a frontend using a centralized server, or run important business logic on a centralized server before writing to the blockchain. Centralization eliminates many (if not all) of the advantages of blockchain over the traditional model.
