In 2024, the total value locked (TVL) of Bitcoin sidechains reached a new high of $2 billion
In 2023, the surge in Bitcoin inscriptions has aroused the enthusiasm of crypto users. Inscriptions have opened up more possibilities for Bitcoin, which was originally used mainly as digital gold. Currently, the total number of Ordinals inscriptions has exceeded 68 million.

Bitcoin reached a new high of $73,000 in 2024, and the halving event has re-attracted market attention to the world's most valuable cryptocurrency. This year has also been the year of explosive growth in Bitcoin's second-layer solutions - the total locked value of Bitcoin's second layer exceeded $2 billion in 2024 before falling back slightly.
Footprint Analytics
As of July 31, Merlin dominates the BTC second-layer ecosystem, holding 44% of the $1.76 billion in total locked value. Bitlayer follows closely behind with 19.6%, and Rootstock with 10.31%. The total locked value of these three chains accounts for three-quarters of the total TVL.

BOB exceeds 130,000 unique addresses, 740,000 BTC bridged from gateways!
BOB is a hybrid second layer backed by Bitcoin and Ethereum, launched on May 1, 2024. Since its launch, BOB has gained a large number of users, with over 133,000 unique addresses. The weekly active addresses chart shows that the user peak exceeded 30,000 in early June. Although the number has dropped slightly, the 30-day moving average of active addresses remains around 16,000, indicating good user retention.

Developer engagement on BOB is rising, approaching 300 active contract addresses per week. This continued growth demonstrates the platform’s appeal to developers building and deploying smart contracts.

BOB Gateway enables users to easily exchange Bitcoin for Wrapped Bitcoin, thereby earning returns efficiently. So far, 8,712 users have used the gateway to complete the exchange of 13.521 BTC (about $734,090.24).

Bitcoin spot ETF issuers suffered nearly $10 billion in losses on BTC holdings
Over the past eight months, Bitcoin spot ETF issuers have cumulatively held 4.5% of the circulating supply of Bitcoin. However, Bitcoin price volatility has had a significant impact on the dollar valuation of their holdings. Since early August 2024, during the crypto market crash, their BTC holdings have lost nearly $10 billion in value.
Flipside - @AliTslm
Since the Bitcoin ETF was approved, Grayscale has been reducing its holdings while other issuers have been increasing their BTC holdings. In addition, at the end of July, Grayscale launched a low-cost Bitcoin spot ETF called Grayscale Mini and transferred most of its holdings to this ETF.
Flipside - @AliTslm
Grayscale was the dominant Bitcoin spot ETF issuer for several months. However, as Grayscale began to profit by selling its BTC holdings, other issuers began to increase their holdings. This shift led to BlackRock becoming the largest BTC holder.

Bitcoin L2 Stacks Active Accounts Reach All-Time High
Bitcoin Summer has energized the Bitcoin second layer (L2) ecosystem. In June alone, Stacks, the leading Bitcoin L2 in developer activity, attracted over 134,000 active users. This surge in new users is attributed to several key developments: the approval of Grayscale Stacks Trust, optimistic news about Stacks and the SEC, and the inclusion of wBTC signer BitGo into Stacks’ signer network. These developments in compliance and institutional adoption have put Stacks in the spotlight.
signal21.co/stacks
Stacks is the only Bitcoin L2 with native Bitcoin (BTC) rewards. In the most recent cycle (every 2 weeks), more than 40 BTC ($2.2 million) was distributed to a group of Stackers. Stackers is an open decentralized network where users stake STX to secure the network. Everyone can stake their STX to earn BTC rewards.
signal21.co/stacks
The increase in users flocking to the Bitcoin decentralized finance ecosystem on Stacks can be attributed to the 60 million STX TVL milestone achieved by Stacking DAO, the leading Bitcoin L2 liquid staking protocol on Stacks that allows users to stake their STX, earn stSTX, and use it in DeFi protocols.

The $180 Billion Opportunity in Bitcoin’s Untapped Potential
Michael Zhao’s report Bitcoin Renaissance explains how Bitcoin’s usage potential can be seen by using the ratio of total value locked (TVL) to market cap. Currently, 17% of Ethereum’s value is used in decentralized applications (dApps), but Bitcoin only uses 0.06%. If Bitcoin can reach Ethereum’s share, it will unlock $180 billion in value. This is a conservative estimate, as developers usually test on low-cost blockchains first. The new BTC L2 technology aims to expand Bitcoin’s use beyond value storage. Rootstock is a key player in this space, as the earliest Bitcoin sidechain, developing this market by leveraging its infrastructure secured by Bitcoin’s hash power and EVM compatibility.
Footprint Analytics
To capture the $180 billion opportunity, Bitcoin technology needs to expand its utility, driving the development of BTC L2 (second layer solutions). The Spartan report states that Rootstock is one of the "four major BTC L2" networks. In the first six months of 2024, Rootstock showed strong growth, benefiting from the Bitcoin halving and partnerships with Uniswap, The Graph, Open Ocean, and Wormhole to improve its cross-chain interoperability. Other BTC L2s in the market are going through the maturation process that Rootstock has already completed. Rootstock's transaction slope remains positive, proving its advanced development.

1,300 Bitcoin in Sovryn’s FastBTC in 2024 — Existing protocols within the Rootstock ecosystem are key to demonstrating market fit. Sovryn has demonstrated this potential with its FastBTC bridge, processing more transactions than all other non-native bridges to BTC L2 combined, highlighting the huge demand and potential for these solutions.
Footprint Analytics
Transaction-level Alpha: This is the first transaction to be dispute-verified using Bitvmx on the Bitcoin mainnet. The Bitcoin L2 space is expanding, and this technology is paving the way for building secure, efficient, high-performance Bitcoin bridges. The existence of this transaction demonstrates that it is possible to verify SNARK proofs on Bitcoin without a Bitcoin hard fork or OP_CAT.

BVM - Pioneering Rollup-as-a-Service on Bitcoin Surpasses $8.2M TVL
BVM is the leading Rollup-as-a-Service (RaaS) platform on Bitcoin, allowing anyone to easily deploy and run a Bitcoin L2/L3 for just $99/month, no coding required. You can use BVM to customize your rollup on Bitcoin, providing multiple modules, including data availability solutions such as Avail DA, Celestia DA, etc. You can also choose ZK Rollup and OP Rollup, as well as different hardware attributes to build your own Bitcoin L2/L3. Rollups powered by BVM can achieve high speed (<1 second block time) and low gas fees ($0.001 per transaction), opening up possibilities for consumer applications on Bitcoin. The total locked value (TVL) of blockchains deployed on BVM reached a new milestone of $8.2 million, with NakaChain, EAIChain, and RuneChain being the main contributors to this growth.
bvm.network
BVM recently launched Bitcoin RaaS Studio, a no-code tool that enables anyone to create a Bitcoin rollup in less than 2 minutes. This visual programming editor from BVM is completely self-service, allowing you to easily design your rollup blockchain by dragging and dropping modules, similar to the Scratch user experience. Currently, more than 10 projects are running their own rollups using the BVM technology stack, and more than 243,000 wallets have been created on the mainnet.
bvm.network
By optimizing costs through integration with data availability solutions such as Filecoin, Polygon, Avail, and Celestia, BVM is helping developers build more efficient and sustainable projects in DeFi, AI, and more. With the support of BVM, Eternal AI and Bittendo optimize costs by leveraging Celestia for data availability. This makes it one of the most efficient rollups, with a cost of only 0.02 TIA per MB.
