Writing about Web3
Tokenization
January 20, 2026
Tokenization is moving from experiment to production infrastructure. Traditional financial institutions are launching parallel digital venues with 24/7 operations, instant settlement, and stablecoin rails—not retrofitting existing systems, but building new ones from the ground up.
