Original Title: BTC Ecosystem Returns? A Quick Overview of Recent Hot Project Developments
Recently, the Bitcoin ecosystem's overall activity has increased, with many long-developing projects entering delivery or new milestone stages, such as RGB, SAT 20, and BRC 2.0. Odaily will briefly outline the progress of these projects in this article for ecosystem players to explore potential opportunities.
RGB Protocol: First Token on Mainnet Will Reopen for Claiming on August 14
The RGB protocol launched on the Bitcoin mainnet on August 7, simultaneously issuing the first token on the mainnet, RGB, with a total supply of 21 million, using a fair claiming model, but each claim requires a fee of about $4.
According to community estimates, RGB token claiming was expected to take about 24 hours, but the actual situation is that after 5 days, the claiming progress is at 60%. The main reason may be the overwhelming popularity, with website traffic and claiming queue being too long, and Bitlight Labs performing multiple server upgrades and pausing claims to implement defense measures against bots.
According to the official announcement, Bitlight Labs has basically completed defense measures against bot claims and plans to release Bitlight Wallet v1.1.3 and reopen RGB token claiming on August 14 at 17:00, but this time only opening 10% of tokens for claiming testing. If the test results are satisfactory, they will gradually reopen the remaining RGB token progress.
Although the RGB protocol's mainnet launch did not meet user expectations and faced significant FUD, from the claiming process, Bitlight Labs continues to develop, improve, and actively combat bot claiming, to some extent maintaining the fairness and token distribution, preventing massive token concentration among a few, which is beneficial for future community development.
Even without an official trading market, distributed RGB tokens can be directly transferred via wallet, with the current price of a single RGB (50 tokens) ranging from $10-13, achieving a 2-3 times return compared to claiming costs. Therefore, after the reopening on August 14, claiming competition may further intensify.
BRC 2.0 Upgrade: First Phase Postponed to September 2
BRC 2.0 is an upgrade to the BRC 20 protocol by Best in Slot, aiming to enable EVM-compatible smart contract functionality for all BRC 20 tokens. Best in Slot originally planned the first phase of the BRC 2.0 upgrade on the mainnet at block height 909969 (around August 14), enabling 6-character BRC 20 tokens and launching a launchpad, but due to insufficient preparation, they postponed the upgrade to block height 912,690, approximately September 2.
Perhaps due to the delayed upgrade date, Pre-BRC 2.0 asset market value has overall declined. The first BRC 2.0 concept NFT Adderrels currently has a floor price of 0.0076 BTC (about $900), down 60% from its peak. However, the Adderrels project continues to operate, updating details on staking NFTs to receive token airdrops, which will be distributed over three seasons, releasing 8%, 9%, and 10% of total supply respectively, with the first season's token airdrop to be distributed on September 2 during the BRC 2.0 launch.
Another project claiming to be the first Pre-BRC 2.0 token minted on Ordinals, LIQUID, has moved to community CTO. Previously, the original LIQUID project team intended to sell the entire project, causing panic. Currently, LIQUID's price is 0.00006 BTC, close to its minting cost.
SAT 20 Protocol: SatoshiNet Mainnet Launched
The SAT 20 protocol is a BTC native asset issuance and circulation protocol developed over two years, with its core feature being asset binding to satoshis, moving freely with them. SatoshiNet is a Bitcoin native Layer 2 built on the SAT 20 protocol, based on Lightning Channel + parallel BTC network, existing to expand the liquidity of BTC mainnet native assets, supporting multiple protocol assets like Ordinals, Runes, OrdX, and BRC 20. SatoshiNet's mainnet officially launched on August 8, 2025.
SatoshiNet's core lies in four contract capabilities: Asset Launch Contract (LaunchPool), Asset Transcend Contract, AMM Trading Contract (Swap), and Limit Order Contract, providing instant settlement, extremely low fees, and Bitcoin asset compatibility.
Currently, SatoshiNet has deployed four transcend contracts for BTC, pearl, rarepizza (ORDX assets), and DOG•GO•TO•THE•MOON (Runes assets).
Despite building for two years and forming a solid community, the SAT 20 protocol has not yet created a wealth effect significant enough to attract broader attention.
Bitcoin Native Layer 2 Spark: Launchpad Initiated
Spark claims to be a Bitcoin native L2 built for payments and settlements, not supporting smart contracts, with its own token issuance standard LRC 20. On August 11, Spark protocol's one of two node operators, Spark browser sparkscan Flashnet, conducted LRC 20 AMM function testing, but the test was not smooth.
On August 6, Fiamma, a Bitcoin wealth management platform, officially launched, enabling BTC transfers to 11 chains including Ethereum, Arbitrum, Aptos, BNB Chain, and Base.
