Trustless Ethereum as a Common Standard for dApps and IoT
EDCON 2025 · 19 Sept 2025 · 7:09
Steffen Kux examines the trust dependencies created when decentralized applications rely on RPC providers. He explains how stateless clients can retrieve blockchain data with cryptographic proofs instead, and considers verifiable access for IoT devices, mobile applications and systems spanning multiple networks.

Ste welcome our next presenterans. Mr. FL [Musik] thank you very much. Let's assume the following situation. September 1st. Quite normal day normal day.
Der ist investor David well known in the space trading all days with crypto. On this day he plans to take his wallet spend 1000 e change it to USDC. about million on day to be secure uses wallet simulates transaction looks fine after he makes small transaction 0 to make works s action receives some few dollars in c looks
fine now it's time to make big transaction. He executes it. Everything looks normal. What he doesn't know is that his RPC provider oder the RPC provider of the wallet is compromised. So confident that everything will work fine. He sends the transaction and seconds later he receives a lot of worthless to looking like C. contract what happen think is
likely unlikely event I want to remind you on the bible tag some months ago in in the begin of this year was in hack was bic exchange did transactioning looked complicing story nobody would story but if we have a way that something can be compromised
mostly just a matter of scenarios could harm for applications notit attack react on attack better still think that unlikely I want to remind you of one tru eent applicationsing
on datac services services providing information trust them information is correct i state don't trust ever RBC ask for information verify all the results by yourself otherwise you are not sure if this information is correct or not. So how can we verify this information in our applications in our devices directly?
Of course that can verify based on the network state full sychon information verify any information out of the box is decentralized. Nobody don't need to trust anybody for information. same is with lights with lights we simply don't read all the data in beginning but we are synchronizing the block headers as well and we have information to make at least all the proofs the other way is that verify the data based on cryptographical proofs and this is what stateless etherum means.
stateless Etherum clients or trustless stateless clif information in the device by ourselves. provider information belongs specific block and get consensus layer proof that know block is actually part of blockchain two proofs can verify completely autonomously information correct information nobody canong providers
stateless we buil such stat in mvp right now willased later this year as the productive version fully stat means it doesn't need to synchronize or store any state available for etherum right now and fornosis L2 L1 verifying local very small fit in any application about 200 KB only zero dependency don't need any other dependen to use it and you can even run it on smartphone run it on IoT device
small enough to be used in any conditions Ja, mention alreadyas MVP available check out use and the productive release will be available within the next month. Once again, don't trust always verify verify everything. Thank you very much. Stay safe and try to verify all information using applications. Thank you.
