Agalta Protocol: A Layer 2 solution with the best overall performance

Since its invention in 2016, Ethereum has become the most active and busiest blockchain network after years of repaid development. It is the undisputed NO.1 public chain in all perspectives, including richness of ecology applications, on-chain assets scale, token security and other core indicators.

In 2021, with the emerging of digital currency bull market in the past few months, the transaction frequency of digital currencies deployed in the Ethereum network increased massively, resulting in a significant increase in network usage, especially the bursting in DeFi area. This makes a desperate lack of the original throughput.

For a long time, the entire crypto community has been working hard to solve the throughput and high gas fees problem of Ethereum. One of the major solutions is Ethereum 2.0, which will increase TPS greatly. But is it possible to fix this from another perspective? The answer is yes, it is Layer 2.

About Layer 2

As we all know , the biggest weakness of ETH is the performance. ETH uses full nodes ,which led to low speed and congestion during transactions. ETH came up with the solution of sharding to improve its performance, means to divide Ethereum blockchain into several shards, put nodes in different shard to participate in accounting and consensus. After sharding, Ethereum become a number of relatively smaller blockchains, and the amount of nodes on each shard is significantly reduced. Thus improve work efficiency greatly.

However, sharding based on current situation causes great challenges for development and upgrades, as Ethereum is working constantly everyday and already has a lot of nodes and data.

What is Layer 2? Literally , it refers to the second layer of network. The logic is to transfer and process transactions from Ethereum’s main chain Layer 1 (L1) to Layer 2( L2), then send results back to Layer 1 for confirmation. We call this solution Ethereum Layer 2.

Simply put, Layer 2 develops another blockchain outside the Ethereum main chain, transfers transactions on Ethereum to Layer 2 for further processing, and sends results or briefing back to Ethereum blockchain. The theoretical TPS of L2 reaches 2000-4000, which surpasses Visa’s processing capacity-1700 transactions per second. Therefore, many people believe that the L2 solution is the hope for Ethereum to win the future.

At present, Layer 2 ecological construction has been carried out in full force, and design schemes in different types have received support from a certain amount of community users. However, the trilemma (i.e. decentralization, security and scalability, only two options are achievable) remains an unavoidable issue for most schemes. However,   Agalta Protocol provides another thinking to solve this for the market.

About Agalta

Agalta is a decentralized cross-chain protocol featured by its high-speed, security, and reliability. It is one of the first expansion protocols that support Ethereum , and can efficiently solve the congestion and high gas fees problems of Ethereum .Through side chain expansion technology, Agalata extends the internet to existing and future blockchain, Agalta helps developers to build Dapp quickly, and carry out large-scale commercial applications.

Agalta Protocol is committed to the construction of the public chain Layer-2 cross-chain DeFi ecosystem, will launch multi-chain cross-chain research and development plan as scheduled, and gradually open Layer-2 high-speed cross-chain network of Binance Smart Chain, Huobi Eco-Chain, Polkadot Main Chain, OKT and other public chains. As well as the enterprise development toolkit. One click fork of Defi projects and products on Ethereum will also be available here. And Agalata will become a cornerstone of the global public chain Defi eco-system.

Intoday’s market, Layer 2 solutions like Rollup and State Channel are emerging, including some repetitive functions. Many investors tend to be speculators and ignore some common problems of projects. For example, in the economic model of Optimistic Rollup Protocol, each batch sequencer of epoch needs a smart contract called bond administrator to be marked as collateral. To become a collateral sequencer, a fixed amount of ETH has to be added to the contract. This economic model can prevent the sequencer from becoming abnormal, but it does not fix the potential risk that the verifier may try to send a large number of fraud proofs to the blockchain in different batches (Forcing a large amount of L1 calculations ).

Celer,  a representative project of the State Channel.  Even though the side chain channel in its network can significantly reduce required collateral deposit, it still has to be proportional to channel numbers and replay capacity of a singal channel (such as payment). This requires massive liquidity in Celer network to ensure normal running of State Channel. Besides, usually the State Channel requires users from both sides to be online all the time, otherwise fairness and security cannot be guaranteed. This kind of availability lackness limits State Channel’s application greatly.

Aalta Protocol technical advantages

Agalta Protocol carried out in-depth research and innovation to solve the common problems mentioned above. And proposed a new generation of Layer 2 Agalta solution: namely , a high-performance cross-chain Protocol that supports multi-chain ecology. Specifically, it has the following highlights.

● Decentralized network: An efficient, safe, and credible decentralized side chain network. The first layer-2 expansion protocols that support Ethereum features scalability and robustness.

● Cross-chain anchoring: AGAT provides a two-way anchored Aga-adapter (adapter) for ETH and other ERC-20 tokens to transfer them to the Agalta chain and provide an EVM-compatible execution environment for DeFi applications.

● AMM model: The newly optimized AMM model automatically prices assets by using the pricing algorithm in the smart contract and creates a liquidity pool for each transaction token. The AMM pool provides liquidity for asset transactions in an automated manner.

● Ultra-high TPS: On the high-performance cross-chain network based on the Agalta API framework, the theoretical TPS performance is as high as 140,000+, far exceeding the existing blockchain transaction performance.

● 0 Gas fee: The unique layer-2 architecture avoids network congestion and the high gas fee. The 0 gas fee allows users to trade freely without worrying about high handling fees and network delays

● Real-time transactions: All transactions are migrated to Layer-2. Users can conduct real-time transactions without waiting for the confirmation time of a block.

● Privacy and security: Based on the advantages of blockchain distributed structure, anonymity and non-tamperable data, the data privacy of transaction users is fully protected, which avoids personal data leakage and data loss

Layer 2 solutions comparision

Now let’s compare all the representative projects in the market in a table

Comparison of Layer-2 Expansion Technology Routes

  State channel     Plasma Optimistic Rollups ZK Rollup Agalta
Typical project Celer, Pisa OMG, Matic OVM, Fuel zkSync, Loopring Agalta
Concept The state channel provides direct one-to-one transfer between two addresses. However, a large number of calculations involved in the interaction between users are calculated and communicated in an encrypted and secure way under the chain. The final settlement of the balance takes place in the expansion plan on the Ethereum main network.   Ethereum’s second-tier expansion framework, based on the main chain (chain-in-chain). Anyone can create different Plasma based on the main chain to support different businesses. Plasma cannot guarantee the safety of the sub-chain, but it can guarantee that users can safely retrieve their assets and return to the main chain when a security incident occurs.   Responsible for a lot of computing under the chain, and security on the chain. A two-layer expansion technical route that ensures the correctness of the state update under the chain by using fraud proof technology.   Responsible for a lot of computing under the chain, and security on the chain.

The US ESTA allows UK citizens to enter the United States without a visa through a visa waiver program. British citizens who plan to travel to the US for tourism, work, or connecting flights must secure an ESTA authorization before their trip. The UK is among the countries eligible to request an ESTA. British travelers can avoid the visa application process in the US by registering with the US Electronic System for Travel Authorization (ESTA). ESTA was founded in 2009 with the purpose of handling data from travelers who arrived in the US via the Visa Waiver Program (VWP). The data is used to establish if a visitor poses a security or immigration risk to the United States. Applicants must meet the US ESTA standards for British citizens in order to obtain this travel permit. An approved ESTA allows British nationals to visit the United States for up to 90 days for tourist, business, transit, medical, or short-term study. You must apply for a B1 business visa or a B2 tourist visa if you intend to stay in the United States for more than 90 days. British nationals with a valid ESTA can visit the United States many times. An approved ESTA is valid for two years or until your passport expires. If your ESTA expires, you will need to apply for a new one permit. The ESTA application form for UK citizens is quick and easy to fill out. Be sure to apply for an ESTA online before traveling to the United States to ensure you are eligible to enter the country.

US ESTA REQUIREMENTS FOR BRITISH CITIZENS

Canada Visa For Norway, Poland, Portugal, Romania, Slovakia Citizens

Published

on

CANADA VISA FOR NORWAY CITIZENS

Every traveler from Norway is required to get a visa before they can travel to Canada. Norwegian citizens must obtain a Canada eTA visa for common reasons like tourism, business, transit, or short-term medical visits. Before arriving in Canada, Norwegian nationals need to obtain a travel authorization. The implementation of the Electronic Travel Authorization (eTA) system by the Canadian government in 2016 has greatly sped up this process. Norwegian individuals wanting to visit Canada for up to 180 days have the option to easily request a visa exemption online using the eTA application form. A valid electronic travel authorization for Norway allows for many visits and allows the bearer to remain in Canada for a maximum of six months per visit. Once issued, the Canadian electronic permit is automatically linked to the traveler’s passport. A Canadian eTA is valid for five years or until the expiration of the associated passport, whichever comes first. It is now possible to obtain a Canada eVisa waiver from Norway exclusively online via the simple eTA application, eliminating the need to visit a Canadian Embassy or Consulate to apply for a travel authorization in person.

WHAT ARE THE REQUIRED DOCUMENTS TO APPLY?

  • Passport – all applicants who wish to obtain a Canada ETA must be passport holders. However, before you apply, check your passport’s expiry date because it needs to maintain its validity for at least another 6 months from the date of arrival in Canada.

  • E-mail address – while the Canada ETA is electronically linked to your passport, you will receive a copy of the authorization via e-mail in PDF format. You are not required to have a physical copy on you, but you can still print one out just in case you need it.

  • Means of payment – You can use a credit/debit card or PayPal account to pay for the eTA fees.

CANADA VISA FOR POLAND CITIZENS

Just like citizens of other countries, Polish people do not need a visa to visit Canada for a short period. The Canadian government implemented the eTA in 2016 to make it easier for Polish citizens to get a travel permit. Every Polish citizen must request a visa waiver or a visa before traveling to Canada. Polish individuals need to obtain a Canada eTA visa for reasons like tourism, business, transit, or medical visits in Canada. Individuals who plan to remain in Canada for up to 180 days have the option to easily submit an online application for an authorized eTA, which will be electronically connected to their passport. If you plan to travel by air, it is mandatory to obtain a Canadian ETA beforehand. Once the electronic permit is issued, it is automatically associated with the traveler’s passport. An approved Canadian eTA is valid for 5 years (or until the associated passport expires, whichever comes first). The application process only takes a few minutes. Polish citizens can now apply for a Canadian eTA (Electronic Travel Authorization) online, eliminating the need to personally apply for a document to enter the country at an Embassy or Consulate.

Canada Online Visa Requirements for Poland Citizens

  • Passport – to acquire a Canada ETA your passport needs to remain valid for at least another 6 months from your date of departure. Otherwise, your ETA could be rejected.

  • E-mail address – Provide a valid email address because your ETA and any news about it will arrive in your e-mail.

  • Means of payment – before submitting your application, you will be asked to make the payment. So, use your credit/debit card.

CANADA VISA FOR PORTUGAL CITIZENS

If you live in Portugal, you are lucky because the ETA is expected to come from Canada. Individuals from Portugal must apply for a Canada eTA visa to travel temporarily to Canada for reasons like tourism, business, transit, or medical purposes. Since the Canadian government started in 2016, they have made this process much easier by introducing the Canadian eTA (Electronic Travel Authorization), which allows Portuguese residents to have multiple entries lasting 6 months each during its validity period. Taking into account the Canada ETA is essential when planning your trip to Canada. This document is not accessible in every country. Certain nationalities have the privilege of being able to submit an application. Portuguese individuals visiting Canada can stay for a maximum of 180 days without a visa but must secure travel authorization beforehand. An eTA visa waiver for Canada eTA from Portugal is valid for a period of 5 years or until the expiry date of the traveler’s passport. It allows multiple entries into Canada through any of the country’s airports during this period, but not entry into the country through a land or sea border. However, a Portuguese citizen can stay in the country for a maximum of 180 days on each entry. For longer stays, travelers must apply for a different type of Canada visa. The Canadian ETA will be linked to the traveler’s Portuguese Passport and is read by electronic immigration machines at the border upon arrival. The eTA Canada for Portuguese citizens was introduced to speed up the process of obtaining a Canada visa waiver from Portugal and can be conveniently applied for by the traveler own home. The ETA application for Portuguese citizens is a simple process and involves completing a Canadian ETA application form online.

Requirements for Canada Visa for Portuguese Citizens

  • A bio-metric Portuguese passport, valid for at least 6 months from the proposed date of arrival in Canada.

  • An application form which is completed online, and which includes personal details such as the traveler’s full name and date of birth, as well as your Portuguese passport number, date of issue, and date of expiry.

  • Online payment via credit or debit card is required before the travel authorization approval process can begin.

  • An email address is required to finalize the application and to receive communication about the eTA’s approval.

CANADA VISA FOR ROMANIA CITIZENS

Romanian individuals looking to stay in Canada for six months can easily request a Canadian eTA online before their air travel. All Romanian citizens planning a short stay in Canada must have this mandatory eTA visa. Romanians, along with people from 52 other nations, can apply for a Canadian eTA allowing multiple entries into Canada for up to six months. Launched in 2016, the Canadian eTA program is designed to streamline the procedure for acquiring travel authorization for visa-free foreign visitors, such as individuals from Romania. Due to the introduction of the online visa waiver system, there has been a notable reduction in waiting times at the Canadian border. Those who are traveling for tourism, business, medical or consultation purposes, or transiting the country en route to their final destination are eligible to apply for an eTA. Once they have received an approved electronic permit, Romanian passport holders can travel to Canada without a visa. An approved Canadian eTA allows a maximum stay of 6 months in Canada with each entry, while its full validity is 5 years for airport entry from the date of issue or until the expiry date of the associated passport. Applying for a Canadian eTA is a quick and easy process. Romanian citizens can easily access the application form through the Canada Online Visa website.

WHAT ARE THE DOCUMENTS’ REQUIREMENTS?

  • Valid passport – verify that your passport has a valid date of six more months from your arrival in Canada.

  • An e-mail address – before entering your email, make sure it is really valid because all communication will be done through this email.

  • Means of payment – to finish your application, you must make a payment and for that, you can use a credit/debit card or PayPal account.

CANADA VISA FOR SLOVAKIA CITIZENS

In the year 2016, a new online system for travel permits was implemented by the Canadian government for specific nations. The procedure for obtaining permission to enter Canada has become faster and more convenient. Slovakia is one of the nations that do not need a visa to enter Canada. People with Slovak citizenship are eligible to obtain the Canadian eTA (Electronic Travel Authorization). Slovak citizens looking to visit Canada for tourism, business, transit, or medical reasons need to request a Canada eTA visa. The Canadian eTA is electronically connected to the holder’s passport. It is valid for several trips during its validity period, as long as each trip is no longer than 180 days. Slovak passport holders who are interested in moving to Canada for a more stable period and who are interested in full-time employment, or academic opportunities should note that the eTA does not cover them. For this purpose, they need to arrange a visit to the Canadian Embassy and request more information. Eligible Slovak candidates can access and complete the Canadian eTA application form, which typically takes less than 30 minutes.

REQUIREMENTS OF CANADA VISA FOR SLOVAKIA CITIZENS

  • A valid travel document or passport in order to apply for Canada eTA.

  • A valid credit or debit card or PayPal account to pay for the Canada eTA.

  • A valid email address, to receive the Canada eTA in their inbox.
