Concordium Protocol 10 Launches: Completely Solves Blockchain Transaction Fee Pain Points

On March 10, 2026, at 10:04 (GMT), the Concordium mainnet officially activated Protocol 10 at block number 43582381, marking a crucial milestone in its blockchain infrastructure. The core breakthrough of this upgrade lies in: transaction fees are no longer mandatorily borne by the sender, but a "sponsor" mechanism is introduced, where a third party commits to pay the fees through an independent cryptographic signature, realizing the decoupling of fee responsibility.

This is the tenth protocol evolution of Concordium since its inception, proposed, voted on, and passed independently by the validator node network without any downtime. As the third step in infrastructure optimization following the previous two upgrades, Protocol 10 aims to eliminate the last and most stubborn friction point in the Web3 experience – the burden of users having to pay their own Gas fees.

On traditional blockchains, regardless of the transaction scenario, the transaction fee is always paid by the initiator. This model is acceptable for personal transfers, but it seriously hinders the integration of consumer-grade applications and enterprise-grade systems. When companies need to process high-frequency, auditable token flows, fee uncertainty becomes an operational bottleneck. Protocol 10 solves this problem through a dual-signature mechanism: the sender signs the transaction content, and the sponsor separately signs the fee commitment. Both need to be verified by the protocol, and the sponsorship commitment is bound to a specific transaction payload and cannot be reused or transferred. Concordium's transaction fee is fixed at 0.01 to 0.02 euros, with no congestion premium, and supports all on-chain operations, not limited to token transfers. More importantly, Concordium's sponsorship mechanism is built on a unique identity layer. Since the genesis block, all wallets have been linked to verified real-world identities. This means that sponsors are not paying for anonymous addresses, but are clearly aware, within the framework of privacy protection, that the object of their funding is a compliant individual or institution. This feature significantly reduces sponsorship risks, making enterprise-level sponsorship models truly feasible and paving the way for financial-grade applications.
