The Baking Sheet - Issue #150

This Week in the Tezos Ecosystem

Nairobi on the Horizon

Welcome to this week's issue of the The Baking Sheet, your weekly newsletter for all the latest and greatest in the world of Tezos.

Great work by the Tezos community to vote, Nairobi, has passed the exploration phase which is a strong signal that this proposal will be implemented. We will now enter the cooldown period for the next two weeks before going into the final voting phase

Week by week, you can see the Tezos ecosystem evolve. This week we will focus on a refresher for Nairobi, another grand scale Tezos event, and an airdrop targeted at ETH users — Let's Dive In!

Nairobi -- Why it's Significant

Never. Stop. Evolving. — That has been Tezos motto since the launch of mainnet as the only blockchain that consistently upgrades in the most efficient manner with actual consensus. After implementing a significant upgrade, the Tezos developer ecosystem were have already proposed a new upgrade named Nairobi.

What does Nairobi consist of? This new protocol proposal contains a variety of updates and improvements, including an up to 8x increase in transactions per second (TPS) for specific manager operations, a revamped gas model for signatures, and faster consensus.

Increased TPS Through Finer-Grained Gas Model

The Nairobi protocol proposal refines the gas cost model for signature verification of manager operations, making their cost dependent on the cryptographic curve used and the payload size. This finer-grained approach enables a significant increase in the maximum number of manager operations that can be included in a block. The result is an 8x performance boost for specific operations, such as basic Tezos transactions between tz1 or tz2 accounts.

Endorsements Rebranded as Attestations

The term "endorsement" is being replaced with "attestation" to more accurately reflect the role of bakers (validators) in the Tezos ecosystem. Attestation better communicates the fact that validators merely attest to the production of a valid block, rather than endorsing the block's content. This change begins with the deprecation of the endorsing_rights RPC endpoint and the introduction of attestation_rights as a replacement.

Faster Consensus Through Fine-Tuned Validation Pipelining

The Nairobi proposal fine-tunes the Mempool module to speed up consensus by validating and propagating consensus operations more efficiently. This update allows bakers to communicate their votes in the pre-attestation voting phase faster, resulting in quicker consensus on block proposals.

Continuous Improvement of Smart Rollups

Smart Rollups, Tezos' general-purpose Layer 2 solution, is evolving with additional host functions and new internal Layer 2 messages, which notify all rollups of new Tezos protocol upgrades on Layer 1.

AirGaps newest product: AirGap Knox

AirGap created by Papers, the same organization responsible for successful Tezos dApps like the DeFI platform Youves, Oracle service Acurast, and voucher system Ecoo is now back with a new product launch: AirGap Knox.

AirGap was also one of the the first to utilize Tezos' Sapling feature, which enables optional privacy-preserving smart contracts for dApps, allowing for private and anonymous transactions.

AirGap Knox, is a new feature that enhances security by automatically disabling all forms of network on an OS level, assuring true offline security. Once installed, AirGap Knox blocks all connections - wifi, cellular, NFC, or Bluetooth - on a deep system level, preventing them from being reactivated. This converts the device into a genuine hardware wallet.

This Week in Tezos Development

Blockchains have a problem — It is hard to implement major upgrades. Fundamental changes are possible through socially coordinated hard forks, but this method has several issues:

  • There is a technical risk of a temporary network split due to incompatible nodes running in the network.

  • There is a social and economic risk of a permanent network split due to the lack of a formal process for resolving disagreements.

  • It is unclear who has the final say. The core devs? The stakeholders? Or people with the loudest voice?

This difficulty in updating blockchains hinders their ability to integrate innovations, leading to technical stagnation. What we need is a chain that can seamlessly evolve while minimizing technical and social risks.

And from this need, Tezos, the self-amending blockchain, emerged.

Nomadic Labs released an article on the next the Nairobi protocol upgrade, which introduces new features and improvements to Smart Rollups, making them more developer-friendly. The key points to note:

  1. Nairobi Protocol Upgrade: This proposal comes on the heels of the recent Mumbai upgrade. Nairobi will improve Smart Rollups for all on Mainnet, including those deployed prior to Nairobi's activation. It reaffirms Tezos core developers' commitment to continuously maintain and improve Smart Rollups.

  2. Protocol_migration Internal Message: Nairobi introduces a new type of internal message called Protocol_migration, which alerts Smart Rollup kernels of new protocol activations. This allows the kernel to take advantage of new features as they become available.

  3. Typed_transactions_batch Outbox Message: Nairobi introduces a new kind of outbox message that allows the kernel to specify the types of the batched transactions it wants to execute on Layer 1. This addition addresses potential vulnerabilities related to untyped transactions.

  4. First WASM PVM Upgrade: Nairobi features the first upgrade to the WASM Proof-generating Virtual Machine (PVM), an important aspect of Smart Rollups. Nairobi introduces the WASM PVM version 2.0.0-r1, which is key to the new features in the protocol upgrade. The upgraded PVM is backwards compatible with the interactive fraud proof system introduced in Mumbai.

  5. Stack Size Limit Increase: The stack size limit of the WASM PVM has been significantly increased in version 2.0.0-r1, making it more compatible with the standard execution engine, Wasmer.

  6. Two New Host Functions: Version 2.0.0-r1 of the WASM PVM introduces two new host functions – store_create and store_delete_value. The former lets you preallocate large values in the durable storage, while the latter is a more specific version of store_delete that only deletes the value under a given key.

  7. Warning against store_get_nth_key: The article advises against using the store_get_nth_key host function due to potential incompatibility with the refutation game.

Overall, the Nairobi upgrade will make Smart Rollups easier and more secure for developers.
