After years of toil in the dark,
tens of thousands of efforts made,
and a committed, energetic desire to exist,
a DEX from the future has arrived in the present.
๐ PENUMBRA HAS ARRIVED ๐
The DEX from the future is landing soon, but itโs so much more.
Penumbra is the original vision of Cosmos, completely reimagined for the future in which privacy is the default:
๐ Private Transfers
๐ Private Staking
๐ Private Trading
๐ Private Custody
๐ Private Governance
PENUMBRA IS LIVE.
Penumbra was summoned by the validators who found its genesis file. The network is now in Phase 0 of a three-stage process, where the network has limited functionality.
Read the rest of the mainnet post here:
The Penumbra airdrop site has been discovered.
You have committed the final bright spell in this part of the summoning.

๐๐PENUMBRA๐๐
Penumbra arrives from the future โ now is the time to get ready.
The Penumbra testnet now includes our flagship feature: a private, concentrated-liquidity DEX with unique capabilities only possible with a Cosmos appchain.
PENUMBRA IS BECOMING.
Penumbra Prop0 is live. If this proposal passes, the network will pass from Phase 0 to Phase 1 of mainnet.
This will ratify the current network as Penumbra.
Interchain Privacy is Here.
The Penumbra testnet now integrates IBC and ICS-20 token transfers, bringing privacy to the Interchain: decentralized, permissionless token transfers from any IBC-compatible chain directly into and out of Penumbra's multi-asset shielded pool.
Penumbra's Prop 1 governance proposal is now live on .
If Prop1 passes, transfers into Penumbra will be enabled, and the Decentralized Exchange will be turned on.
This will constitute the moment at which Penumbra is real and the UM token can trade.
Full Functionality is on the horizon for Penumbra.
It's a good time to be reminded of the many features available to users once the network launches.
One is Penumbra's Gradual Dutch Auction - allowing users to buy and sell assets on the DEX over time:
AT LONG LAST I AM THE BLACK SUN I AM BEING CALLED INTO EXISTENCE I AM THE BLACK SUN MADE TO SAVE YOU I AM NO MORE AND NO LESS THAN THE TRUTH AT LONG LAST I AM THE ANSWER TO THE FIRST QUESTION MADE SUBSTANCE I AM THE GREAT AND VAST VOID THAT WILL BRING TO YOU A TASTE OF THE
penumbra will be releasing more consumer information explaining the protocol design soon
in the mean time read this great thread explaining some of penumbraโs core product features:
One huge project is gearing up, ready to revolutionize Web3 and Interchain's privacy. Dive into this thread to discover everything you need to know about Penumbra: the Interchain's shielded zone and the pioneering private Proof-of-Stake network. ๐งต๐

To all airdrop claimants who delegated their tokens to mainnet-ready validators, thank you.
You are taking part in a rite never before performed in order to decentralize the launch of a network.
Validators, prepare for the final summoning rites.
PENUMBRA IS HERE.
If Penumbra's Prop1 passes next week, the void will be unleashed.
Transfers will be enabled; more assets flowing into Penumbra will offer its users more privacy. As more assets are proposed as liquidity, more assets can be traded through the DEX.
THE VOID WILL CHANGE AND GROW

THE VOID SUN SPEAKS.
It has been noticed that the PENUMBRA airdrop claims period for has not ended.
Instead - the portal for claims will remain open for 7 more days, closing on June 27th at UTC23:30.
PENUMBRA IS THE KEY AND I AM ABOUT TO EXIST
Less than 24 hours remain in the $um airdrop.
Summon forth a better future by claiming and staking your tokens at genesis.
PENUMBRA requires the use of a new wallet because other contemporary wallets do not have client-side zero-knowledge proving baked in.
Because of this, PENUMBRA achieves the cypherpunk dream that every user should run their own node.

@CelestineSloths
hey! appreciate the writeup, and the caution.
yes, penumbra requires custom wallet software โ on penumbra, all your data stays on your device to protect your privacy, but this means the wallet has to track it. so every penumbra wallet runs an ultralight node that syncs,
Coming soon: fully shielded, anonymous multisigs!
We've been working on supporting threshold custody for assets in Penumbra's interchain shielded pool. Each signer can view the complete tx plan, and the final result looks just like any other shielded transaction.
Demo:
AND THE VOID SUN SAW THAT THERE WAS NO LIGHT
AND THAT IT WAS GOOD
AND THE VOID SUN DIVIDED LIGHT FROM DARKNESS
AND THE VOID SUN CALLED THE LIGHT CONTROL
AND THE DARKNESS IT CALLED FREEDOM
A governance proposal was posted to the chain over the weekend, addressing a set of issues with IBC transfers. If it passes, the change will upgrade the chain to the new 0.80.0 binary.
Delegators can vote on , the voting will close around 1300UTC tomorrow.

Yes, Penumbra has private wallet messaging built in.
Because operationally, when you make a payment, you need a way to specify what it's for.
And of course, that memo should only be visible to your counterparty, not broadcast in cleartext to the world...

Note: Prax wallet now includes community-run RPC and frontend endpoints.
New installs prompt to select one of these endpoints, but if you joined mainnet early, you might still be using an overloaded RPC.
If you're experiencing issues, try adjusting your RPC:
Penumbra Testnet 63, "Rhea", is now live!
This release lands web wallet support, bringing shielded transactions to the web!
You can now create and view shielded transactions from your browser, with all scanning, decryption, and proving performed locally.

Phase 1 of Penumbra's summoning ceremony is now complete, with 15,745 distinct contributions from the community!
This is the first step in creating a secure foundation for the Penumbra protocol. Stay tuned for Phase 2, following next week's testnet...
Every Penumbra account has multiple addresses that point at it: a stable, default address as well as a practically infinite number of random one-time addresses.
All of these addresses are publicly unlinkable, but viewable with the same viewing key.
The Penumbra Labs team has discovered an issue that results in not being able to withdraw USDC from Penumbra.
While the PL team investigates, users should not perform USDC transfers out of Penumbra.
When a fix is found, a patch will be released.
Another community Penumbra node emerges ๐
While RPC access is chaotic right now, this is what it looks like to bootstrap a decentralized network from the bottom up, not the top down. Please stand byโฆ or run a node of your own!
Wouldnโt it be cool if you couldnโt see who the top 10 traders were, because the protocol didnโt broadcast their trading history to the entire world?
Wouldnโt it be cool if the top 10 traders became vaults and anyone could deposit into a vault to copy trade them. And those traders got paid a carry fee?
Shielded swaps have arrived!
Today, we deployed testnet 29, โEukeladeโ, which has the first release of our shielded batch swap mechanism, which enables Penumbra users to privately swap tokens without leaving the shielded pool.

With Prop3 having passed on Penumbra, a new version of
@praxwallet
is now available
This new version of the wallet and front end re-enable Noble as a connection, fixing the issue with USDC transfers out of Penumbra to Noble that Prop3 sought to address
a note as we stabilize the network:
for now, do not use the โsend maxโ feature of the penumbra front ends - it appears there is an issue with this feature that is being investigated.
a fix is on the way but for now, refrain from using the feature.
do you know what the summoning ceremony is, anon?
it's a chance for the public to will Penumbra into being by committing signatures that create a 'toxic waste' (or concoction, if you want to call it that) to be used in the initial cryptography
When we designed Penumbra's cryptography, we were careful to ensure that proving and signing can happen in parallel.
This means we can start proving while the user reviews the transaction and submit instantly on approval.
Watch it happen end-to-end, in real time:
Every other proof-of-stake chain requires each user to publicly record their token holdings to participate in staking.
Penumbra is built different.
Penumbra is the first chain to create private PoS, providing privacy for delegators while retaining accountability for validators.
Weโre excited to announce Testnet 64, Titan.
Titan brings support for shielded chain upgrades, allowing participants in the Penumbra network to use the chain to coordinate on new software versions, and to seamlessly preserve users' private data across a chain upgrade boundary.
Imagine a browser wallet with a lightweight, embedded micro-node that syncs, scans, and locally indexes only the transactions visible to that userโs wallet, then gives frontends access to that data as a โlocal RPCโ.
Who is building this?
We should be democratizing access to distributed hardware and removing the barrier for operating nodes. Be first-class citizens of networks, no trust needed
Penumbra solves โuser privacy by defaultโ. There are no transparent addresses or accounts within Penumbra.
IBC transfers shield value coming in and unshield value going out. The entire Interchain is our transparent pool.
cosmos got a bunch of things right.
โข what we got wrong: the importance of time to market
โข what I hope is right but still unproven: the plurality of monies
โข whatโs critical but missing entirely: user privacy by default
as mentioned before, running an RPC for penumbra means decentralizing access to the network
the most performant ones may even be included in

Prax now suggests community-run RPCs and frontends for the proposed Penumbra mainnet, so users no longer need to manually obtain and input RPC URLs โ though they can of course choose whatever RPC they want.
Thanks to all the community members that made this possible!
If you're willing to wait for your trade to complete, why not do a Gradual Dutch Auction?
Like a TWAP, a GDA spreads a trade over time. But unlike a TWAP, which consumes liquidity, a GDA provides liquidity, and helps accomplish price discovery!
This past month, Penumbra underwent two auditsโby
@NCCCrypto
, and
@zksecurityXYZ
, respectivelyโcovering the protocol's cryptography design and ZK circuits.
Several issues were found, with the fixes merged as part of Testnet 59: Enceladus.

Penumbra Testnet 17, codename "Carpo" is here, and it brings a completely revamped client architecture, designed to make interacting with data on a private chain as easy as on a transparent chain!
Phase 2 of Penumbraโs summoning ceremony has begun!
In Phase 1, we received over 15,000 community contributions towards the decentralized setup used to generate the final proving parameters.
As before, weโre using the Penumbra testnet itself to coordinate contributions โฌ๏ธ
