Stellar activates Protocol 28 as network hits record throughput and RWA value climbs

Stellar activated Protocol 28 as the blockchain hit a new sustained throughput record, adding tools designed for larger smart-contract deployments.The network ran Protocol 28 by Sept. 17 after a scheduled mainnet upgrade vote a day earlier. The release lets developers move groups of Soroban smart contracts to new code at once and introduces changes intended to make contract data easier to migrate as applications evolve.The upgrade coincided with a fresh performance milestone. Blockchain analysis firm Chainspect said Stellar averaged more than 211 transactions per second across 100 consecutive blocks, its highest sustained throughput on record.Protocol 28’s CAP-85 targets protocols that run multiple instances of the same smart contract. Developers can now have those contracts reference an externally managed executable, so changing the shared reference moves every participating contract to new code in a single atomic operation.That can narrow the window during security fixes or software migrations when some contracts are running updated code while others remain on an older version. Adoption remains optional, meaning existing Soroban applications must choose to implement the new archi...
