We're excited to welcome in a new year with public POSDAO in production, STAKE governance and many exciting integrations on the horizon. We'll be updating our 2021 Roadmap over the next few weeks with additional development and project goals for the year.

Chain Usage Updates

xDai usage has already hit milestones in 2021! Since Jan 2 xDai has handled over 100K Tx/day.

Usage from the current Dark Forest round as well as increased adoption of trading platform have led the tx/day charge. Gas usage has also been increasing. As DF tweeted, gas usage on xDai exceeded gas usage on Ethereum in the first week of 2021. We expect some usage to taper off as the DF round ends at 11:59 pm EST, and it's been a great example of xDai's ability to scale and support applications that simply can't run on Ethereum at the moment.

:woman_astronaut: POSDAO Update

Public Staking on POSDAO continues to gain traction, with close to 100 delegators (80 unique) participating and nearing 400K STAKE staked in the protocol. We are excited to welcome our first 100 unique active delegators with an exclusive POAP - details coming soon. To be eligible, we recommend delegating in epoch 39!

BlockScout incorporated a new Apps Menu which includes links to Staking, EasyStaking and more.\

As we pause to reflect on 2020 (pause playing DarkForest for a few minutes anyway 🙂 ) we are first and foremost grateful for the xDai community, users, and partners who have elevated the xDai chain and made it a resounding success. We could not have envisioned the level of adoption and number of projects that have flourished on xDai in 2020**. xDai is arguably the #1 most-used L2 scaling solution for Ethereum right now**, and has helped support the ecosystem by providing an option for low-cost, stable transactions while improving interoperability and cross-chain interaction.

Prior to 2020, a primary use-case for xDai centered around live events. xDai was experiencing a lot of growth with usage at Ethereum conferences, the Splunk Conference, RSA conference and more. At EthDenver 2020 xDai was used by conference attendees to buy food as well as navigate the conference, vote on hackathon entrants, and earn quest-based NFTs. The EthDenver Burner Wallet was extremely ambitious, pointing a way for the future of xDai as the go-to solution to power conferences and live events.

Then live events shut down. xDai could still be used for virtual events (and was adopted by KickBack to host their virtual events) and was still actively used by several projects, such as Grassroots Economics community currencies, but these also relied on face-to-face community interactions. Fortunately, xDai had several things going for it:

  1. Fast 5 second blocks.
  2. Stable inexpensive transactions.
  3. Robust open-source toolset (BlockScout, TokenBridge, and more).
  4. Interoperability, compatibility and synchronicity with Ethereum.
  5. Long-standing track record as a production blockchain.
  6. Strong developer and grassroots community.

In 2020 we set out to make xDai stronger and more decentralized by enabling governance and upgrading consensus to POSDAO, our own unique delegated proof-of-stake consensus. We cultivated partnerships, notably a primary partnership with Gnosis, and worked with many projects and DAOs to find creative solutions to navigate high gas fees on Ethereum.

We set ambitious goals for 2020, and were able to achieve them without compromising chain security, always the #1 directive of the team. Below are some highlights from a very busy year:

  • EthDenver 2020: Before the Covid hit the fan, xDai powered this final large-scale Ethereum event.
  • POSDAO Phase 1 (nominated validators): After over a year in development, private POSDAO launched April 1,2020.
  • ****🥩 STAKE token launch: A major milestone towards xDai decentralization, the STAKE governance token was offered as an IEO through Bitmax on April 28 and trading opened April 29. It was the first token to participate in the Bitmax pre-staking program. After launch, STAKE was added to other exchanges, both centralized and decentralized. Exchange list.
  • ****👍 EasyStaking launch on Ethereum: EasyStaking launched to enable users on Ethereum to keep their STAKE on Ethereum while earning emission rewards. Rewards are divided between EasyStakers and Liquidity providers on Uniswap. EasyStaking is still a great option for users, and over 1M STAKE are currently in the EasyStaking contract.
  • Project migrations / launches: Too many to name, see the projects section for a more complete list. Highlights include: Circles UBI, Perpetual Protocol,, DarkForest, Foundation, POAP, Vocdoni & HoneySwap.
  • ****🤝 Partnerships & Integrations: Major announcements of integrations with Gnosis, Chainlink & HOPR.
  • DAOs: DAOs found xDai the perfect solution for community voting and governance processes. DAOHaus, MetaCartel, Raidguild, PrimeDAO and others moved their operations.
  • ****🌉 OmniBridge: The omnibridge lets users to easily transfer any ERC20s between Ethereum and xDai. This interoperability solution gives users instant access to Ethereum as needed. The architecture was developed by TokenBridge, and UI a collaborative effort with RaidGuild.
  • Reddit competition: Though no winner has been announced, xDai had a strong showing which brought a lot of attention to the value proposition offered by the xDai stable sidechain. The competition showcased xDai as well as the experimental qDai implementation. Reddit Gitbook
  • ****💸 Fiat onramp: Ramp network integration allows users to buy xDai directly with a debit card.
  • BlockScout, TokenBridge, Nethermind, and Dev Tools: The BlockScout and TokenBridge teams both made major improvements to their open-source products to support the xDai chain. BlockScout introduced the POSDAO staking app, bridged tokens list, contract validation methods and many more features. TokenBridge worked to improve the xDai Bridge and the Omnibridge. Nethermind optimized for POSDAO, creating a 2nd client option for nodes. The toolset for developers also expanded with many projects deploying their infrastructure to xDai.
  • Governance expansion: Bridge governance was extended to additional validators, and community voting was enabled through snapshot to further decentralize the xDai chain.
  • ****⛽ Gas consumption milestone: In November, total gas consumed on xDai hit 1,000,000,000,000+. Transactions on xDai steadily increased over the year, with some larger spikes due to Dark Forest, Circles UBI and xDai is exceeding 80K tx per day as the year comes to a close.
  • ****📰 Media features: As xDai came into the spotlight as a scalability solution for Ethereum, media outlets also noticed: Coindesk, Bankless, OurNetwork, and more featured coverage of the xDai chain.
  • ****🎉 Public POSDAO launch: The Public POSDAO launch on Dec 23 was a culmination of years of work by the team. Delegation amounts were lowered to 200 STAKE thanks to a community vote, and the first public rewards were distributed to delegatros. We are very excited to move into 2021 with a network that is more decentralized and secure than ever before!

This brings us to playing DarkForest (DF) as 2020 comes to an end. DF on xDai encapsulates much of what made the year a success. DF leverages xDai to provide a real-time experience for users where they can make 1000s of ZKsnark-based transactions without worrying about tx cost or processing delays. This is done with a customized and reenvisioned burner wallet; blockchain novices can start playing immediately without even knowing they are transacting on a blockchain. It’s a fun, real-time strategy game made possible by xDai’s unique blockchain attributes.

Version 0.4 was first introduced on xDai in August, and the heavy infrastructure demands caused some slowdowns for users. The teams learned from these issues, and xDai and Nethermind optimized infrastructure to anticipate tx volume and traffic spikes, creating a much-improved experience this time around. This is just one example of the xDai team's dedication to constant improvements and feature development as blockchain adoption tilts towards the mainstream.

We are now working to expand and develop our 2021 xDai Roadmap. We are very excited for new partnerships, projects and use-cases in the coming year! Here are a few preliminary items we are researching:

  • Consensus (staking) monitoring and analytics integrations
  • Privacy preserving transactions
  • Universal NFT bridge
  • Synthetic Asset exploration
  • Optimistic Rollup / Optimistic Bridge research and integration
  • Expansion of the xDai grant program for developers

We wish you a very happy new year and are excited for the blockchain innovations and developments to come in 2021!

POSDAO Staking Updates

We are very excited to be closing in on the public launch of staking and delegation on xDai. We are completing our final rounds of testing and have been releasing videos on how to complete basic processes such as bridging STAKE, delegating STAKE, and claiming rewards.

See the Become a Delegator section for a basic overview, and the Staking Operations section for details on using the Staking DApp.

We've also drafted an example reward scenario which compares potential staking rewards for EasyStaking, LP Providers, POSDAO delegators and POSDAO validators.

:construction_worker: BlockScout Smart Contract Verification

BlockScout added a new feature with devs in mind to the xDai block explorer instance. Now smart contracts can be verified in 2 ways. It is still possible to use a flattener, but the new method is designed for ease of verification. Devs can simply upload all contract source files and JSON metadata, and the contract can be verified. This feature leverages Sourcify, and makes verification easier than ever.

This week we continued our work on public staking, welcomed the new Ramp direct fiat integration, and were featured in a writeup by Bankless.


Note that we will skip several weekly updates over the holiday season. We did not publish a recap last week, and will skip several weeks at the end of the month.

****💶 Ramp Fiat -> xDai

Although this announcement occurred last week, we did not include in a weekly update and wanted to highlight this important milestone. A direct fiat-to-xDai onramp has been on our Roadmap for a long time! We had previously worked with other providers without success, and were excited this collaboration with Ramp Network could come to fruition. Ramp is currently available in many countries, and they plan to integrate US customers in the near future. Their simple SDK or hosted option allows projects to easily add direct xDai purchases to their apps. We look forward to these integrations, removing one more obstacle for users and creating a seamless crypto experience.

This week we've been heads down on POSDAO preparations and network security enhancements. Progress continues towards the public staking implementation on xDai.

🔥 Token Burn & Public POSDAO Prep

We've burned 40,000 STAKE tokens on Ethereum and added 2 new validator candidate nodes on xDai. Each node has received 20,000 STAKE on xDai, the minimum required to become an initial validator, and will be upgraded to validator status shortly. The nodes are running on the Nethermind client, providing additional robustness and decentralization to the network.

The tokens were burned to the Eth2 Deposit Contract. Learn more about why and some future directions for xDai and public POSDAO.

:closed_lock_with_key: Security Audits

An extensive bridge audit has been completed for the xDai bridge and the OmniBridge. Now that the audit is complete, we are upgrading contracts and will be incorporating additional functionality in the coming months.
