#GM!

1/ How do the cross-chain #bridges works? In this #visualguide, we explain how assets are transferred between chains and how interoperability becomes a fundamental aspect of the future.

#DeFi #Cryptocurrency #Ethereum #Bitcoin $ETH $BTC

2/ Blockchain networks are very fluid and efficient as single entities but lack the ability to communicate with each other. This creates demand for seamless transfer across different chains without using centralized exchanges as intermediaries or selling the token first.

3/ Cross-chain #bridges solve the problem by enabling the transfer of tokens, smart contracts, data, feedback, and instructions between two independent chains without intermediaries.

4/ In general, cross-chain #bridges are divided into two based on the transactions validator: trustless bridge and trusted bridge.

@WrappedBTC

5/ Based on the purposes, #bridges can be classified into:
- Asset-specific @WrappedBTC
- Chain-specific @auroraisnear, @NEARProtocol ~ Rainbow Bridge
- Application-specific @THORChain, @compoundfinance
- Generalized @axelarcore, @LayerZero_Labs

6/ Based on the architectures, #bridges also can be classified into:
- External validators & federation
- Light clients & relay
- Liquidity providers' network

7/ By understanding the #bridges architecture we can look at different traits that explain the strength and weaknesses of each bridge.

8/ Wrapped tokens are an integral part of the #bridges to achieve interoperability. Assets that are transferred to the bridge will be minted in the form of wrapped token that adheres to the rules, data, and contracts (native) on the destination blockchain.

9/ In this diagram we can see how assets move between chains by using the lock & mint mechanism and burn mechanism. These two mechanisms are the most popular and versatile to move assets across multiple chains.

10/ Existing blockchain #bridges face the interoperability trilemma, current designs cannot satisfy all three traits. There is always some level of compromise.

11/ Despite facing the trilemma, cross-chain #bridges are still important because they can increase asset productivity, improve user experience, and support the distribution of liquidity across the chain and decentralized apps (dApps).

12/ #Bridges are not without issues, growing concerns directed toward asset centralization and imbalance of liquidity. Security also becomes a big problem since the massive assets deposited lure hackers to steal and exploit the bridges.

13/ #Bridges attacks not only target the asset custodians, but other targets such as asset issuers, smart contract vulnerability, and bridge users are also prone to security hacks.

@ethereum

14/ Beyond the #bridges: #eWASM is a project to bring highly flexible, near-native performance and optimization of web assembly for Ethereum to achieve interoperability and flourish application developments on #Ethereum.
@ethereum

@Polkadot

15/ Beyond the #bridges: Layer-0 like @Polkadot and @cosmos allows developers to create custom blockchains that can be tailored to their requirements by combining various elements from different L1s while retaining their own ecosystem

$DOT $ATOM

@axelarcore

16/ Beyond the #bridges:@axelarcore, @LayerZero_Labs, @OneAnalog, and @MapProtocol are several examples of projects that focused to bring interoperability across the chains.

1/ What is Maximal Extractable Value (#MEV)? How does it become an integral part of the #blockchain network? How does MEV work? All of your questions will be answered in our latest #visualguide.

#Ethereum #cryptocurrency #TheMerge $ETH #DeFi

2/ In the blockchain transaction ordering process, the block producers are responsible to aggregate, selecting, and reordering transactions in the #blockchain network based on the given economic incentives thus creating opportunities for #MEV

3/ #MEV refers to the maximum value that can be extracted from a block more than the standard block reward and gas fees by including, excluding, and changing the order of transactions in a block

1/ #Perpetuals #futures contract has been the holy grail of derivatives in the #crypto market. We present you our latest #visualguide that breakdown complexity behind future market simplicity with our lead @minnymousegirl

#Cryptocurrency #Bitcoin #ETH #BTC #AVAX #BNB #SOL

2/ A #futures #contract is an agreement to buy or sell a commodity, currency, or another instrument at a predetermined price at a specified time in the future. two counterparties will trade a contract, that defines the settlement at a future date.

3/ A #perpetual contract (Perp) is a special type of futures contract that doesn’t have an expiry date. So one can hold a position for as long as they like. Perp only exists in the #crypto market.

1/ #Lending and #Borrowing (LB) are the most primitive financial services. We will discuss how #DeFi LB solves and enables financial inclusivity with transparency but still maintain #privacy.

#Crypto #Cryptocurrency #Bitcoin #Ethereum #ETH #BTC #AVAX #BNB #SOL #visualguide

2/ In traditional #finance, the intermediaries are appointed banks or financial institutions that act as the bridge between the lender and borrower. All of these services are strictly regulated and monitored by the central #banks.

3/ Despite already existing for a long time, LB in traditional #finance has a long-standing problem: non-inclusive, stringent procedures, arduous verification process, low rate and approvals, and non-transparency.

1/ #Stablecoins have become inseparable part of #DeFi and gained immense popularity in early 2022. After the disaster of $UST and $LUNA, demand of stable medium of #exchange never dissipated.

#Crypto #Cryptocurrency #Bitcoin #Ethereum #ETH #BTC #AVAX #BNB #SOL #visualguide

2/ #Stablecoins are stable-price digital assets. These coins are 'pegged' against reserved assets. Unlike digital assets such as Bitcoin and Ethereum, which are volatile, stablecoins value remain relatively stable.

3/ Digital assets such as Bitcoin and Altcoin are subject to high volatility in the market, making them hard as store of value and medium of exchange. #Stablecoins designed to provide stable value of asset.
