During the wait for the final result of the Bitcoin spot ETF, the market has been highly focused on the ecological construction of Bitcoin. Previously, Jademont, the founder of Waterdrip Capital, stated that there will be at least 10 Bitcoin Layer 2 networks launched next year, which will greatly promote the development of Bitcoin's ecological infrastructure in terms of traffic.

However, building on Bitcoin, which carries the Satoshi Nakamoto vision, remains a controversial choice. Previously, Bitcoin Core developer Luke Dashjr claimed that Mimblewimble is a "bug" that exploits vulnerabilities in the Bitcoin network, and called the Ordinals protocol a scam, sparking a heated debate within the community about the value of Mimblewimble.

A few days ago, Adam Back, CEO of Bitcoin technology company Blockstream, publicly stated that the high fees brought by confidential transactions have driven the adoption and innovation of Bitcoin Layer2. He believes that "trying to stop (confidential transactions), they will do it in a worse way." This statement from the Bitcoin OG has also led many crypto users to choose to believe in the narrative of Bitcoin Layer 2.

The inscriptions before opened the narrative of Bitcoin asset issuance, and the future scenarios of these inscriptions cannot be realized on the Bitcoin main chain. They need to build application scenarios on the Bitcoin L2. Some community users bluntly stated that "whether Bitcoin Layer 2 is necessary is entirely a market choice, not a planned outcome."

Before the inscription boom drove the great development of the Bitcoin ecosystem, there were already some Layer 2 projects for Bitcoin, such as Rootstock (RSK), which uses merged mining to ensure security comparable to Bitcoin; Stacks (STX) has also made a strong comeback this year, with a 55.6% increase in the past seven days. Stacks has undergone several key network upgrades this year, including version 2.1, which introduces decentralized mining and bridging with Bitcoin.

Nowadays, a new batch of Bitcoin Layer 2 solutions with certain attention has emerged in the market. BlockBeats has compiled several projects worth paying attention to, but readers should be reminded that the Bitcoin ecosystem is still in its "pioneering period" and investment should be cautious.

MAP Protocol

MAP Protocol is a Bitcoin Layer 2 for peer-to-peer cross-chain interoperability. On December 7th, MAP Protocol announced that it has received strategic investment from Waterdrip Capital.

By utilizing the security mechanism of Bitcoin, MAP Protocol enables assets and users from other public chains to seamlessly interact with the Bitcoin network, enhancing network security and achieving BRC20 cross-chain capability. Through MAP Protocol's BRC-201 cross-chain extension protocol for BRC-20 tokens, BRC-20 and ORC-20 assets on the Bitcoin network can interact with other tokens on other public chains.

MAP Protocol's native tokens are MAP and MAPO, which are the same token but differentiated by different codes for the chains they are on. On December 18th, MAP Protocol announced a large-scale token burn, totaling 133,886,020 MAP/MAPO tokens, which accounts for 5.9% of the circulating supply.

Dovi

Dovi is a Bitcoin Layer2 solution that is compatible with EVM smart contracts. Its aim is to enhance scalability, reduce costs, and promote a more secure and decentralized financial ecosystem. On December 11th, KuCoin Labs announced a strategic investment in the Bitcoin Layer2 solution Dovi and established a partnership. Its native token DOVI was listed on the KuCoin exchange on December 12th.

According to the white paper released yesterday, Dovi's application scenarios mainly include high-speed transaction functions, allowing users to make quick and small payments, suitable for daily shopping and online services; developers can design and deploy complex smart contracts on the network without worrying about transaction speed and cost; enterprises can use Dovi for large-scale asset transfer and management; educational institutions and researchers can explore new applications of Bitcoin and blockchain technology in fields such as economics, computer science, and sociology.

The official website shows that the next step for Dovi is to release the testnet, establish a developer community and ecosystem support, and launch Dovi V1.

x.TAI

x.TAI Network is a Bitcoin Layer 2 scaling network based on AI encryption algorithms. It integrates technological innovations such as AI, DeInfra, and Layer2, aiming to establish a development environment and ecosystem that aligns with the development of inscriptions.

On December 8th, x.TAI announced a live demonstration of the XRC20 protocol encryption process. It is the first protocol to incorporate the GRU and Lorenz Hyperchaotic System into the Bitcoin Layer 2 scaling network. Through witness compression technology, x.TAI has achieved a highly private and low-cost Layer 2 network environment. Additionally, x.TAI disclosed that it has received $1.2 million in funding for future technology development and expansion.

DFS Network

DFS Network is a Bitcoin Layer2 project under construction. After its launch, various inscriptions issued on the Bitcoin network can be traded on DFS Network and DeFi, games, and other applications can be built on it.

According to official information, DFS is the mainnet token of DFS Network, with a total supply of 10 million. 1 million DFSN were fairly distributed on the BTC chain, and 2.5 million DFS were fairly distributed on the EOS chain. The remaining 6.5 million will be fairly released through liquidity mining. The relationship between DFSN and DFS is 1 DFS = 1 DFS and 1 DFSN = 1 DFS + 1 meme (BRC-20).

BeL2

On December 20th, Elastos plans to launch the Bitcoin Elastos Layer 2 (BeL2) network, aimed at attracting Bitcoin transactions from the new platform's staking tools. After the announcement, Elastos' native token ELA saw a 56.2% increase in 24 hours.

BeL2 integrates with the Elastos Smartweb Chain (ESC) and Bitcoin, allowing for more complex Bitcoin transactions beyond the basic Bitcoin blockchain, including smart contracts and irreversible digital protocols. These smart contracts are immutable and transparent, and can operate without the need for third-party intermediaries.
