ECADInfra has voted yay in the exploration phase of Tezos L1 governance for Tallinn, and we intend to vote yay on the remaining phases. We’ve also voted in favor of the Farfadet kernel upgrade for Etherlink. We’re excited about the progress being made toward the Tezos X vision of a multi-runtime blockchain ecosystem.
Tallinn looks lovely, but we’re a bit disappointed Tipperary was passed over for naming—even if it is a county and not a city.
Tallinn Protocol (PtTALLiN)
Tallinn reduces mainnet block time from 8 seconds to 6 seconds. This isn’t a simple parameter change—the protocol recalibrates cycle lengths (10,800 → 14,400 blocks), adjusts the per-block gas limit (1.39M → 1.04M gas), and updates smart rollup timing parameters to preserve existing challenge windows and commitment periods. The result is faster finality—two-block confirmation drops from 16 to 12 seconds—without increasing hardware requirements for validators.
The protocol also introduces the “All Bakers Attest” mechanism, which activates once 50% of active bakers use BLS (tz4) consensus keys. This shifts consensus participation from a slot-based lottery to weighting by actual baking power, leading to more predictable rewards and broader participation in block finalization.
On the technical cleanup side, Tallinn removes legacy adaptive issuance voting code from block headers (now that AI is permanently active) and fixes a subtle gas accounting bug in the contract cache. New Michelson instructions (INDEX_ADDRESS, GET_ADDRESS_INDEX) provide opt-in storage optimization for contracts with heavy address usage.
Etherlink Farfadet
Farfadet brings Etherlink’s EVM from Prague to Osaka, adding support for four new EIPs including secp256r1 curve precompiles (EIP-7951) and the CLZ opcode (EIP-7939). Network capacity increases from 14 MGas/s to 27 MGas/s—nearly doubling throughput.
The upgrade also makes receipt roots Ethereum-standard compatible (EIP-2718), fixes event emission for the FA bridge, and optimizes storage to maintain only the latest block rather than full history in the kernel (full history remains available via EVM nodes).
Notably, Farfadet includes a feature flag for the experimental Tezos runtime—a key building block for cross-runtime composability under the Tezos X architecture.
Looking Ahead
We’re optimistic about where these upgrades are taking the ecosystem. Faster L1 finality directly benefits Etherlink’s data publication speed. The All Bakers Attest mechanism strengthens consensus security. And the groundwork being laid for multi-runtime execution opens possibilities for novel cross-chain applications.
At ECADInfra and our sister company ECAD Labs, we’re actively preparing for this multi-runtime future. Our work on Taquito (the TypeScript library for Tezos) and Signatory (remote signing infrastructure) aims to provide developers with the tools they need to build across runtimes with confidence. We believe composability between Tezos-native contracts and EVM execution environments will unlock new categories of applications, and we want the tooling to be ready.
About Tezos Governance
Tezos features on-chain governance, allowing the protocol to evolve through a structured amendment process. Proposals go through multiple phases: Proposal, Exploration, Cooldown, Promotion, and Adoption. Bakers vote on behalf of their delegators, making governance participation a key part of our service.
We voted yay in the exploration phase of Tezos L1 governance for Tallinn, and we intend to vote yay on the remaining phases.

Staking With ECAD Infra
We believe in the power of Tezos staking. ECAD Infra charges a 5% commission on staking rewards. To stay aligned with compliance best practices, we only support protocol-level reward distributions. We don’t pay third-party delegator rewards directly—if any rewards are accidentally sent to us, we’ll put them toward coffee and R&D.
About ECAD Infra
ECAD Infra provides high-performance, production-grade blockchain infrastructure that’s designed for scale, resilience, and decentralization. Some of our standout technical features and operational practices:
Bare-metal, high-throughput servers We run core infrastructure (RPC, validators, and supporting services) on bare-metal hardware engineered for maximum throughput and minimal latency.
Redundant connectivity and multi-ISP architecture Multiple ISPs, load-balanced routing, and redundant network paths ensure high availability and near-zero downtime even if individual connections fail.
Colocation in top-tier data centers We deploy in premier, carrier-neutral facilities that provide advanced security, compliance standards, redundant power, and robust climate controls.
Truly decentralized by design We avoid reliance on major cloud providers (AWS, GCP, Azure) for core systems, favoring infrastructure we directly control. This strengthens decentralization and aligns with blockchain principles.
Cross-chain experience & scale Since 2018, we’ve operated public RPC and validation nodes across multiple blockchains, refining the operational rigor needed to serve high-demand, production environments.
Ecosystem collaboration As part of the same group as ECAD Labs, we combine infrastructure know-how with developer tooling expertise. Our operational learnings feed back into Signatory and other tools, while we share best practices with the broader Tezos and validator communities.
