An summary of Athens, the primary Tezos on-chain improve proposals

The Parthenon in Athens, by Hans Reniers

This put up summarizes at the moment’s announcement from Nomadic Labs concerning Athens, the primary on-chain Tezos improve proposals for Tezos arriving later this week. For a extra technical clarification and changelog, please learn Nomadic’s put up straight.

And naturally, for a full overview of the Tezos governance mechanism, please try “Amending Tezos and the visualization under:

What’s within the Athens proposals?

The proposed modifications within the two Athens proposals are incremental:

Athens Proposal 1: enhance the gasoline restrict

  • The gasoline restrict was set conservatively at launch to guard the chain, with the concept that it might be elevated by way of the modification course of
  • This proposal would enhance the gasoline restrict by permitting double the computation steps in every block whereas holding the variety of IOs carried out in every block unchanged
  • This can make it incrementally simpler to deploy good contracts on Tezos, however maintains the gasoline restrict at a conservative degree as Nomadic Labs awaits extra detailed benchmarking outcomes
  • Nomadic Labs goals to suggest additional gasoline restrict will increase and a re-weighting based mostly on ongoing benchmarking efforts

Athens Proposal 2: enhance the gasoline restrict (see Proposal 1) AND scale back the roll dimension to eight,000 XTZ for Tezos Proof-of-Stake

  • In present Tezos consensus, a baker will need to have 10,000 XTZ to be randomly chosen to suggest or endorse a block
  • Along with rising the gasoline restrict, this modification would cut back that threshold to eight,000 XTZ, incrementally reducing the barrier to entry to baking

Please notice that past these two incremental modifications, the improve proposals additionally embrace minor fixes which don’t considerably change the protocol, as described within the changelog.

Benchmarking Athens

Nomadic states of their announcement put up that they carried out in depth testing to make sure the proposed protocols behave as supposed and that the migration to Athens wouldn’t use a very burdensome period of time and disk house.

For the gasoline prices, Nomadic based mostly the brand new gasoline limits on a sensible mainnet context, with the brand new limits nonetheless set conservatively to make sure the community runs easily.

Outdoors of the proposals, earlier this month Nomadic introduced a brand new characteristic for Tezos nodes to enhance storage by way of “Snapshots” and “Historical past Modes”, as detailed in this weblog put up. As famous in at the moment’s put up, Nomadic hopes to combine the snapshot characteristic into Tezos nodes throughout the subsequent few weeks, bettering storage efficiency.

Nomadic examined the consequences of roll dimension discount for each sorts of nodes: full nodes adopting the snapshot characteristic (permitting sooner sync and fewer storage) in addition to nodes with a full context (i.e. “archive” nodes sustaining historical past of all previous states).

Relating to the proposals extra broadly, Nomadic studies there’s a one-time enhance in disk house and time when the community migrates from the previous protocol to the proposed Athens protocol.

Based mostly on these outcomes, Nomadic deems any efficiency variations between the 2 proposals inconsequential:

This price solely impacts the migration block and has no influence on the following operation of the community. In our opinion, the efficiency distinction between the 2 protocol proposals shouldn’t be vital.

As implied, it’s most necessary to guage proposals based mostly on their longer-term financial influence (e.g. the price of baking, barrier to entry, and many others.) and operational influence (e.g. does the community proceed working easily?), relatively than a one-time price of migration.

Stakeholders will be capable of consider this for themselves within the upcoming Zeronet testing initiative described within the “What comes subsequent?” part under.


As a part of the improve, Nomadic will embrace a modest bill for 100 XTZ:

For this primary replace, we determined to incorporate an instance of invoicing, an on-chain solution to fund the event of protocol proposals. Through the migration, the account of the authors of a proposal will be funded by creating a certain quantity of tez. On this case, we selected a symbolic worth of 100ꜩ, sufficient to purchase a spherical of drinks for the devs who labored on these proposals. Sooner or later, we hope this mechanism can be utilized to fund the work of latest groups and assist enhance decentralization.

Why such modest, incremental modifications?

As described in Nomadic’s first “In the meantime at Nomadic” put up in January:

The primary aim [of the first proposals] is to show that Tezos can perform a profitable replace each technically and as a neighborhood. In spite of everything, we’re all novices to the Tezos governance process and this goals to be a first step in the direction of extra substantial amendments.

As acknowledged, the aim is to reveal the mechanism first earlier than advancing to shinier, extra thrilling upgrades which could lay over the horizon. A 3-month improve timeline permits Tezos to make thrilling advances incrementally and a multi-stage voting mechanism goals to make sure the accountability of proposed modifications to the community.

Why “Athens”?

In final week’s put up, Nomadic Labs proposed a brand new naming conference for Tezos proposals:

Our suggestion is to make use of metropolis names, anglicised and in alphabetic order. After all, sooner or later different entities will suggest protocol upgrades, and it will likely be as much as them to comply with the conference or not. But, metropolis names present a large set to select from for every letter, with even a little bit of room to precise issues.

As an indication, “Athens” is a reasonably apparent alternative for this primary voted improve, don’t you assume?

For illustration functions, one may think future upgrades named “Brasília”, “Canberra”, “Delhi”, and so forth.

Observe: the title “Athens” shouldn’t be supposed to bear any relation to Ethereum’s Constantinople exhausting fork additionally scheduled for later this week.

What comes subsequent?

Protocol hashes, injection, and voting

Later this week, Nomadic goals to supply the protocol hashes and inject the proposals. Bakers will then have roughly Three weeks to upvote the Athens proposals, with the top-ranked proposal continuing to a “Sure/No” exploratory vote for the following Three weeks.

Voting directions

Nomadic will publish directions for bakers on the best way to vote. The Tezos neighborhood also needs to count on to see detailed directions from Obsidian Techniques concerning the best way to use Ledger for voting.


The Tezos Zeronet will likely be reset to supply a public check community with accelerated voting durations every lasting 56 hours lengthy. Utilizing the Zeronet, the complete voting process will be examined over 9 days, permitting stakeholders to research the activation of a brand new protocol safely throughout the check atmosphere.

Sign Your Choice and Be a part of the Dialog

To sign your choice or to test your baker’s choice forward of the Athens vote, please try Stephen Andrews from TezTech’s’ TezVote, a just lately launched vote signaling device based mostly on a easy Michelson contract.

Upon announcement of the primary Tezos proposals final month, preliminary discussions started on Kialo. It’s price noting that new proof will turn out to be accessible as soon as the proposals are injected and entities unbiased of Nomadic consider the proposals.

Count on to see renewed dialogue there and be part of the dialog!
