After Aptos, what are the potential airdrop opportunities?

Original title: "31 Unissued Coin New Public Chain Projects (with Tutorial)"

Original Author: Chasing Wind Lab

< p>On October 19th, the Aptos mainnet was officially launched, and at the same time, about 20 million APT airdrops were distributed to incentive testnet users. Presumably everyone has seen the Aptos effect, and there are more or less examples of making money around you. Aptos proved to us that the strategy of finding unreleased projects still works in bear markets. This article sorts out 29 Layer1 and Layer2 that have not yet been issued for your reference.

4. Iron Fish

Introduction: The name Iron Fish comes from an encrypted communication system built by the United States based on Native American languages during World War II. The project hopes to demonstrate the magical power of cryptography. Iron Fish is a privacy blockchain network that aims to be a common privacy layer for all chains. Iron Fish is a decentralized, proof-of-work (PoW), censorship-resistant, and publicly accessible blockchain project. It is designed to provide strong privacy guarantees for every transaction.

Similar to how the invention of the SSL/TLS layer in the 90s paved the way for e-commerce and benefited countless industries, we believe that privacy is about protecting users and expanding encryption Basic requirements for use. We designed Iron Fish from the ground up as a new cryptocurrency that enables easy-to-use, fully private payments by strictly adhering to the Sapling protocol. Each account is equipped with a viewing key to grant its holder read-only access to that account's details.

Iron Fish is positioned as a Layer1 privacy network. The project adopts the PoW consensus, and will use zk-SNARKs and Sapling protocols to Online transactions provide the highest level of privacy protection. The biggest highlight of Iron Fish is that the network hopes to protect privacy without compromising the accessibility of transactions on the chain. For this reason, Iron Fish is equipped with an additional "readable key" (view key) for each address on the chain. ), the address holder can grant read-only permission to others through this key.

This mechanism is a good solution to the regulatory problems of Layer 1 privacy. Through the "readable key", Iron Fish will allow relevant organizations to View the details of the corresponding address to comply with the necessary Anti-Money Laundering (AML) obligations.

Currently, Iron Fish is still in the second round of incentive testnet stage, and this round of incentive testing will continue until the nodes are stable, fully functional and ready to host All preparations for online launch.

According to the plan, Iron Fish will open up cross-chain bridges with other mainstream blockchains in the future to provide privacy protection for other mainstream assets, so as to gradually realize its ultimate vision - to become the core of the entire Web3 world Privacy shield.

In November 2021, Iron Fish announced the completion of US$27.7 million in Series A financing. This round of financing was led by a16z, Elad Gil, Sequoia Capital (Sequoia) , Electric Capital, Dylan Field, Alan Howard, Jeff Weiner (Executive Chairman, LinkedIn), MetaStable, A Capital, Divesh Makan (Iconiq), Do Kwon (Terra), Matt Luongo (Keep Network), Nathan McCauley (Anchorage), Arrington XRP and others participated in the investment.

5.Anoma

Anoma is a well-known venture capital A private PoS public chain promoted by Polychain Capital. Anoma Foundation is a blockchain technology company based in Switzerland.

Anoma is a structure for self-contained and autonomously coordinated protocols and mechanisms. Built on a foundation of advanced cryptography, programming language theory, and research, Anoma's primary goal is to facilitate private transactions using a digital representation of any value, regardless of who issued it.

The two core concepts of Anoma are "barter" and "privacy". The project hopes to build a service for everyone A privacy payment system that truly returns financial sovereignty to individuals.

The so-called "barter" means that Anoma hopes to create a network that allows any asset to be used as a means of exchange or payment, so that individuals can arbitrarily Select Use Asset Class. It is worth mentioning that any asset here refers to any exchangeable goods, services, or anything that can be digitally represented with intrinsic value, including assets created on Anoma, other assets transferred to Anoma through interoperability agreements Chain assets, and legal tender in the form of Stablecoin, etc.

"Privacy" is better understood. In Anoma, in order to protect user privacy and prevent others from collecting data retrospectively, the sender, receiver, amount and asset denomination will be encrypted and the transfer of funds will be guaranteed using zero-knowledge proofs. In addition, assets on the Anoma network will have a unified shielding pool shared between all assets when they are transferred, rather than shielding each asset individually. In this way, the more participants, the more assets, and the more frequent the transfer, which greatly increases the concealment of asset transfer data.

In April 2021, Anoma completed the first round of financing of US$6.75 million, led by Polychain Capital, Electric Capital, Coinbase Ventures, FBG Capital, CMS Holdings, Lemniscap , Cygni Labs, Walden Bridge Capital and others participated in the investment. In November of the same year, Anoma raised another US$26 million in financing, and Polychain Capital continued to lead the investment, with participation from Fifth Era, Maven Capital, Zola Capital, Electric Capital, CMCC, etc.

7.ESPRESSO Systems

Introduction: Espresso Systems has developed a The Configurable Asset Privacy (CAP) protocol enables digital assets to have custom privacy properties. The first application of CAP is CAPE (Configurable Asset Privacy for Ethereum). CAPE is a smart contract application that asset creators can use to implement new assets with custom privacy and generate CAPE versions of existing Ethereum assets, endowed with ERC-20 and eventually ERC-721 privacy attributes. Although CAPE can run on any EVM blockchain, we will deploy it on the Ethereum Goerli test network as a demonstration as soon as possible, and eventually plan to migrate the application to Espresso Systems' infrastructure and interact with Ethereum assets through the Token bridge .

8.Monad

In mid-April (when Jump hadn't been tossed half to death by Terra), Keone Hon, head of research at Jump Trading, announced his departure and founded Monad, whose vision was to build An EVM-compatible high-performance blockchain that unleashes the potential of the EVM ecosystem by improving the execution efficiency of EVM on a large scale. According to Keone, it is expected that the performance of Monads can reach more than 1000 times that of Ethereum, and can host more complex types of applications, thereby achieving wider adoption.

In Monad's view, thanks to the sufficient user education of Ethereum, EVM has almost become the "standard" choice like Javascript in the web2 world, but There are certain problems in the current expansion path of Ethereum. Whether it is sharding or rollup, the blockchain will be divided into independent execution environments, thereby destroying the composability of the chain. Therefore, it is necessary to build a higher performance underlying network.

In the current Monad's public information, although Monad emphasizes that Layer1 needs to come up with higher TPS to meet the innovative needs of applications, it does not explicitly mention And how Monad will achieve a qualitative leap in TPS. However, we can see from the few sentences on the official website that Monad will most likely focus on low-latency programming, compiler optimization, and multi-threaded computing.

10.Gear

The Cosmos ecology has Canto, and the Polkadot ecology also has Layer1 Gear with quite high expectations. Gear is an advanced smart contract chain that supports WebAssembly (WASM). After successfully taking a parachain slot and accessing it, developers will be able to deploy their Dapps to Gear in the simplest and most effective way within 5 minutes. Thus entering the Polkadot ecology.

In terms of technical features, Gear includes but not limited to the following features:

One is to support a variety of different programming languages, such as Rust, C, C++, etc., which will greatly reduce the entry threshold for developers who are not familiar with the blockchain, and help bring more talents to the industry;

Second, when the application is running in the browser, WebAssembly supports the program to run at a code execution speed close to the local level, which will help improve the actual experience of the user;

The third point is about the interaction of smart contracts. Gear uses the Actor model for communication. This model is shardable and parallelizable in design , allowing developers to use different languages for asynchronous programming, improving the asynchronous processing efficiency of transactions, so that various business logic Dapps based on Gear can run at high speed.

In December 2021, Gear, the Polkadot-based smart contract layer, announced the completion of $12 million in financing. This round of financing was led by Blockchange, Three Arrows Capital, Lemniscap, Distributed Global, Polkadot founder Gavin Wood and others participated in the investment.

11.Celestia

The former name of Celestia is LazyLedger. Celestia is a very special Layer1. The project positions itself as " The first modular blockchain network". Specifically, Celestia will modularize the technology stack of the blockchain network, and at the same time decouple the consensus layer and the execution layer. As a consensus layer, it will only undertake the work of transaction ordering and data availability verification. The specific transaction execution will be It will be distributed over other executive layer networks (such as Celo) linked to Celestia.

The roadmap shows that Celestia plans to launch the test network in 2022, and gradually launch the incentive test network and the main network in 2023. Issue Tokens for PoS staking.

Celestia has certain similarities with Polkadot's "relay chain + parachain" in terms of architecture, and the latter's multi-chain architecture development route does not seem to be for the time being. Not quite, so it remains to be seen if expectations will be fulfilled when Celestia goes live.

Seed round participants include Interchain Foundation, Binance Labs, Maven 11, KR1, Signature Ventures, Divergence Ventures, Dokia Capital, P2P Capital, Tokonomy, Cryptium Labs , Michael Ng, Simon Johnson, Michael Youssefmir and Ramsey Khoury.

12.Fuel

Fuel is the first Optimistic Rollup deployed on the Ethereum mainnet, and is mainly suitable for payment-centric applications. The upcoming Fuel V2 will be based on UTXO's highly parallelizable minimal execution system and enable smart contract support, with Ethereum-style interoperable Turing-complete smart contracts, not just simple transfers.

Progress: Fuel is a modular execution layer. In June, a developer network-based demo application, SwaySwap, was launched, which is an AMM.

Financing: US$1.5 million in financing will be obtained in September 2021, led by CoinFund, with participation from Fenbushi Capital and Origin Capital.

Features: Fuel is an Optimistic Rollup of Ethereum, which initially expands Ethereum through technologies such as UTXO (unspent transaction output). 1.0 is mainly suitable for payment applications.

However, after the launch of the main network, smart contracts may not be supported due to the lack of use cases, and the amount of interaction is relatively small. So Fuel 2.0 began to transform into a modular execution layer. One of the co-founders of the project, John Adler, is also a co-founder of Celestia.

Fuel officially promotes 3 technical implementations: 1) Parallel execution of transactions through UTXO to improve performance; 2) Launch of FuelVM (Fuel Virtual Machine) to optimize The traditional virtual machine should also solve the EVM compatibility problem; 3) The programming language Sway and the tool chain Forc are introduced for developers.

14.EigenDA

EigenDA is proposed by EigenLayer DA program. EigenLayer itself is the restaking layer of Ethereum.

Founder Sreeram Kannan put forward this point of view: the trust between blockchains and DAPPs is separated from each other, and each has to pay for the maintenance of ecological trust High cost of capital. For example, the Ethereum Beacon Chain now has more than 13 million ETH pledged. To maintain this pledge volume, Ethereum now provides pledged users with an APR of about 5%.

What EigenLayer does is the restaking of funds, allowing pledge users to pledge funds repeatedly to middleware, oracle machines, DAPPs, etc. in addition to PoS pledges, so that Improve capital efficiency and reduce trust costs.

EigenLayer itself is based on Danksharding and ETH staking. EigenDA is a DA scheme proposed by EigenLayer, which is specially designed for Optimistic-Rollup and ZK-Rollup. There is not much information about the project.

15.Assembly

A modular smart contract layer on top of IOTA. Currently in pledge period 3. By staking MIOTA through firefly.iota.org, stakers can get 0.000001 Assembly Token ASMB every 10 seconds. Wallets must reach more than 1 ASMB to receive airdrops. 20% of the total ASMB supply will be allocated to IOTA stakers. Assembly's mainnet is expected to go live this year, when the ASMB transfer function will be enabled.

Funding: Total funding brought to $118 million. Investors include Huobi, LD Capital, HashKey Capital, Signum Capital, etc.

Features: Assembly is based on IOTA. Different from Ethereum's account model, IOTA is based on the UTXO ledger and supports high concurrency, but UTXO is not compatible with smart contracts like the account model. In addition, IOTA also adopts DAG (Directed Acyclic Graph) data structure, which is also conducive to high concurrency.

In the combination of IOTA+Assembly, IOTA can achieve high performance because of UTXO and DAG. Because UTXO is not compatible with smart contracts, IOTA is very suitable for L1 that only focuses on DA and settlement (equivalent to no DAPP and execution layer competing for block space on L1). Assembly is a smart contract layer built on IOTA to support Rollup's smart contracts.

The security of Rollup to the IOTA main chain (transaction validity/fraud proof) is checked by the smart contract chain specially deployed on the Assembly, and the transaction verification is performed by The root chain verifiers with the top reputation rank carry out.

IOTA+Assembly and Polkadot+Moonbeam, and Cosmos+Evmos are similar in structure. The modular smart contract layer provides support for smart contracts such as Rollup and parachains.

Team member Sandy Peng graduated from the University of Cambridge. Co-founder Ye Zhang said that he was doing research in the direction of ZKP four years ago. Haichen Shen studied in Yaoban, Tsinghua University as an undergraduate, and graduated from the University of Washington with a doctorate. His research direction is biased towards the field of underlying systems.

In order to solve the current high gas fees and frequent congestion problems faced by Ethereum, everyone tries to put the settlement layer on Ethereum and transfer the execution to Layer 2 , Scroll uses the zk-Rollup technology, which is recognized as the best expansion solution of Ethereum, which greatly increases the transaction speed while possessing the security of Ethereum. However, zk-Rollup is not friendly enough for developers. It needs to use a special programming language R1CS to write smart contracts, which increases the learning cost of developers. Moreover, it does not support composability and has limited functions.

Scroll plans to build an EVM-equivalent zkEVM, using zkEVM as its core component, supporting native EVM verification and composability of applications, making existing Ethereum applications can be easily migrated to this zk-Rollup.
