Institutional investors gain reliable and streamlined access to Tezos through the Seoul upgrade

The

blockchain implemented its 19th protocol update, called "Seoul," on September 19, 2025. This upgrade delivers enterprise-level security, boosts network performance, and simplifies staking processes. Developed collaboratively by Nomadic Labs, Trilitech, and Functori, the Seoul upgrade meets the increasing needs of institutional investors and organizations by introducing protocol-native multisignature (multisig) accounts. This innovation removes the need for external smart contracts when managing shared accounts, enhancing safety and making operations less complex Seoul Protocol Upgrade Brings Strengthened Institutional Security to Tezos and Enables 63x Network Efficiency Gains [ 1 ]. The new multisig accounts use BLS cryptography, which allows multiple digital signatures to be merged into a single signature—an ability not previously available on most blockchains Boarding for Seoul — What’s Packed in Tezos’ Latest Protocol Trip [ 3 ].

The Seoul upgrade also slashes bandwidth and storage needs for bakers by 63 times through the introduction of "aggregated attestations." By combining attestations into just one action per block, the daily data requirement drops significantly from roughly 900 MB to just 14 MB. This enhancement leads to quicker transaction finality and decreased latency across the Tezos network Seoul Protocol Upgrade Brings Strengthened Institutional Security to Tezos and Enables 63x Network Efficiency Gains [ 1 ]. Such improved efficiency is essential for supporting greater institutional participation, as it cuts down infrastructure costs and boosts validator performance. These technical advancements are likely to draw in more bakers, especially those using tz4 accounts that take advantage of BLS signatures—though compatible hardware and software updates will be necessary Boarding for Seoul — What’s Packed in Tezos’ Latest Protocol Trip [ 3 ].

One of the most notable user-focused updates is the "1-click unstaking" feature, which automates the completion of unstaking requests after a four-day waiting period. In the past, users had to manually finish the process to reclaim their funds. Now, anyone on the network can finalize these operations, letting wallets or dApps automate the process Seoul Protocol Upgrade Brings Strengthened Institutional Security to Tezos and Enables 63x Network Efficiency Gains [ 1 ]. This enhancement fits Tezos’ ongoing commitment to improving usability while still protecting users, as tokens remain locked during the waiting period to prevent any misuse You're Not Staking, You're Missing Out [ 6 ].

Industry observers and analysts view the Seoul upgrade as a driver for further institutional participation. The addition of multisig accounts and staking via tz4 addresses closes critical security and usability gaps for larger investors, who need advanced key management options Boarding for Seoul — What’s Packed in Tezos’ Latest Protocol Trip [ 3 ]. The efficiency improvements could also make it easier for smaller bakers to join, encouraging a broader and more decentralized validator community Tezos Bakers: Let’s Get Ready for Seoul! [ 2 ]. According to on-chain analytics, staking on Tezos has consistently increased since the Paris protocol update in June 2024, and staking rewards are now triple those of delegation rewards.

Market sentiment regarding the Seoul upgrade has been generally positive but cautious. Both traders and analysts point out that successful protocol enhancements often build market confidence and help drive prices higher, as long as there are no technical problems. If Seoul is rolled out smoothly, it could further cement Tezos’ standing as a top option for institutional blockchain solutions, especially as rivals like

Thanks to its self-amending governance system, Tezos remains highly adaptable, with the Seoul protocol marking its seventh consecutive year of operation. Its capacity to continually strengthen security, optimize performance, and improve user experience—without the need for disruptive hard forks—makes Tezos a promising choice for altcoin investors looking for sustained growth. As the crypto sector adjusts following the 2024 market peak, Tezos’ emphasis on institutional readiness and efficient operations may draw more large-scale investors focused on reliability and scalability.
