Welcome to the OP Stack, @Whitechain_io.
Whitechain is moving from a standalone L1 to an Ethereum L2 on the OP Stack, focusing on institutional and B2B finance.
The chain will run on OP Enterprise Self-Managed with Mission Critical support, which means their team keeps control of configurations but gets a direct line to OP Stack engineers.
Dev Mainnet is open now.

GM @Immutable
Welcome to Optimism.
Immutable Chain will be upgrading from our custom geth fork to an OP Stack-based chain in 2027.
This means faster transactions on Immutable Chain and stronger ties to Ethereum's security.
All accounts, balances and contracts will carry over automatically, with no action needed for almost everyone.

What do big financial institutions look for when choosing a blockchain?
@Optimism COO, @kylejenke at Ethereum Korea One:
1. Trust and track record. OP has the second-highest uptime of any chain, behind only Ethereum.
2. A developed partner ecosystem that brings global distribution.
3. Control over their own infrastructure, especially privacy and compliance.
And for Korea specifically: people on the ground, engineers on the ground, and local partners.
That last point is the one Korean institutions ask me about most.
