Singapore, Hariankripto –Ethereum founder Vitalik Buterin delivered a speech today September 11, 2023 in Singapore, explaining the concepts of statelessness, Progressive Beacon Chain (PBS), and the ongoing challenges posed by Ethereum’s 20 byte address format. In front of a packed conference room, Buterin outlined his vision for the future of Ethereum, emphasizing the importance of innovation and potential solutions to overcome these challenges.
Buterin started his speech with bold statements,
“If we have statelessness and Progressive Beacon Chain (PBS), ending the state could be said to be a low priority.”
This statement was met with enthusiasm and curiosity, as state expiration has become a recurring issue in Ethereum’s development plans. A key question haunting Ethereum is how to manage data state effectively, especially in the context of an ever-evolving blockchain.
Statelessness, as Buterin explained, is a key concept for Ethereum’s scalability. This allows the network to maintain critical data such as account balances and smart contract status without having to store the entire blockchain history. This development promises to significantly reduce the storage requirements for running Ethereum nodes, a milestone that many in the community are hoping for.
Progressive Beacon Chain (PBS), on the other hand, is the first step towards Ethereum 2.0. This upgrade aims to improve scalability and security, forming the basis of Ethereum’s future growth. Buterin’s remarks hint at how these innovations, when combined, could potentially reduce concerns around the end of the state.
However, the crux of Buterin’s speech was Ethereum’s 20 byte address challenge. Ethereum addresses, being 20 bytes long, have posed scalability and security challenges as the blockchain ecosystem expands. Address conflicts and limited address space have become pressing problems.
Buterin proposed two potential solutions to this problem:
Expands the address to 32 bytes
This approach will significantly expand the address space, accommodating the growing needs of the Ethereum ecosystem. However, this will require widespread adoption and adaptation of existing tools, contracts, and infrastructure to support longer address formats.
Reallocates space for existing 20-byte address format
An alternative solution is to reclaim some of the space that has been allocated in the current 20 byte address format, reducing it to 14 bytes. This will free up address space while maintaining compatibility with existing infrastructure.
In conclusion, Buterin’s speech in Singapore emphasized that with statelessness and PBS, the end of the state may become a secondary concern. Even a state size of 8 terabytes can be managed. However, the fundamental issue of the 20 byte address format must be resolved, both for expiry of state and long-term security reasons.
As Ethereum continues to move towards Ethereum 2.0, overcoming these challenges is key to ensuring the network’s scalability, security, and usability. Vitalik Buterin’s vision sets a promising direction for Ethereum, ushering in an era of innovation and progress that the entire cryptocurrency community has been waiting for.
Ethereum’s evolution promises to bring exciting developments that will shape the blockchain landscape in the coming years.
