Wormhole Guardians — Moonlet

But first off: How does Wormhole work?

Wormhole is a decentralized, generic message-passing protocol for blockchains that enables blockchain interoperability. Today, Wormhole is connected to 13 individual blockchains that are all “first class citizens”, meaning they all have equal priority in the network. Wormhole isn’t built on Solana, Ethereum, Avalanche, or any other connected chain. It is its own separate network, a neutral party that sits in the middle of its connected chains.

Why does Wormhole need Guardians and what do they do?

Wormhole’s 19 Guardians serve as validators that attest to messages they observe on the connected chains. They do so by running a full node for each chain to monitor the Wormhole Core contracts. A message can be generated by any application that has integrated with Wormhole on the source chain. When a supermajority (2/3) of the Guardians sign a message, it produces a VAA (Validator Action Approval) which is a combination of the message itself plus the Guardian signatures. The message is then sent to the destination chain with this promise of the message’s legitimacy. VAAs are then consumed by applications on the destination to facilitate their intended action (wrap a token, count a vote, update a price, etc).

  • what development features will be shipped into production
  • major strategic decisions that steer Wormhole’s direction

Who are those Guardians and why can they be trusted?

Guardians are a key construct in Wormhole’s trust modeling. Because of the role they play in validating the authenticity of messages, the network trusts them to behave in an honest manner. But how can we assume they will?

Who is Moonlet?

Moonlet is a key node operator covering over 30 blockchain networks, with over $50M in AUM (Assets Under Management) and 18k delegations to their nodes. In the past 5 years, Moonlet has been involved in many initiatives building non-custodial staking services (on both desktop and mobile environments), joining incentivized testnet competitions, supporting the launch of several mainnets, and achieving excellence in aggregating technologies on top of blockchain networks. Moonlet is run by a team of ten, based in the EU and US, with backgrounds in software development, product management, devops, and design, with over 15 years of expertise in building complex software solutions.

History of Moonlet

Moonlet started in 2017 as a community of blockchain enthusiasts who tried to understand how Web3 would challenge the status quo of the finance and technology industries. In 2018, they received their first grant and started to build a Chrome extension for a non-custodial wallet solution. A year later, the Chrome extension morphed into a non-custodial digital asset wallet on both iOS and Android. In 2020, Moonlet branched into acting as a PoS Node Operator to provide nodes that support blockchains and ensure networks operate safely and efficiently. In 2021, the Moonlet team started building the TIEXO NFT Marketplace and launched their own NFT collections. In 2022, TIEXO added functions to become a Web3 NFT Aggregator: in intuitive dashboards, users find all statistics and data to all Solana NFT listings.

Branching out into NFTs: TIEXO

Currently, Moonlet is actively building TIEXO, a Web3 NFT Marketplace Aggregator. In order to empower users to make informed decisions, TIEXO brings together information and data from 11 marketplaces, about 6,000 collections, close to 10 million NFTs, and over 1 million individual listings. For conducting payments and to bridge NFTs, TIEXO utilizes Wormhole’s Portal bridge.

Lastly, some stats

In the last 12 months, Wormhole, together with Guardians like Moonlet, has successfully validated over 1.3 million messages across more than a dozen supported chains. We’re looking forward to continuously upping those numbers and building the xChain world together with our trusted partners.
