Ethereum Foundation researcher Justin Drake says the organization is dropping Poseidon in favor of SHA or BLAKE hashes. He calls the change a milestone for Ethereum's post-quantum security.
Why it matters
Poseidon was designed for efficient zero-knowledge proof work, while SHA and BLAKE are established general-purpose hash families. The choice puts Ethereum's cryptographic foundation and proof stack in focus.
Market impact
For ETH, this is a long-horizon security signal rather than a direct trading catalyst. It does not change Ethereum's supply or market structure. The key follow-through is how the choice is formalized and integrated across Ethereum's protocol layers.
Frequently asked questions
-
Why is Ethereum moving away from Poseidon?
Justin Drake described the move toward SHA or BLAKE hashes as a milestone for Ethereum's post-quantum security. The choice concerns Ethereum's cryptographic foundation and proof stack.
-
What role did Poseidon play in Ethereum's stack?
Poseidon was designed for efficient zero-knowledge proof work. SHA and BLAKE are established general-purpose hash families.
-
Does the change affect ETH's supply or market structure?
The decision concerns Ethereum's cryptographic foundation, not ETH's supply or market structure.
-
Is this an immediate ETH price catalyst?
For ETH, the development is a long-horizon security signal rather than a direct trading catalyst. Its immediate price impact is secondary.
-
What should Ethereum watchers track next?
The key follow-through is how the SHA or BLAKE choice is formalized and integrated across Ethereum's protocol layers.
