migration

Binance is expected to suspend the token deposit and withdrawal services for Sei (SEI) network on June 1 at 16:00 to support its migration to the SEIEVM network. After the migration is completed, Sei (SEI) tokens will only support deposits and withdrawals through the SEIEVM network.

On May 14, BNB Chain released the "BSC Post-Quantum Cryptography Migration Report," stating that it has completed the migration testing for quantum-resistant cryptography for transaction signatures and the consensus layer, using the NIST standardized post-quantum signature algorithm ML-DSA-44 (Dilithium) and the pqSTARK aggregation scheme.The report shows that BSC has replaced transaction signatures from ECDSA to ML-DSA-44 and switched consensus voting aggregation from BLS12-381 to pqSTARK to address the potential threats posed by future quantum computing to the existing elliptic curve cryptography system. However, post-quantum signatures also significantly increase the on-chain data volume: the size of a single transaction has increased from about 110 bytes to approximately 2.5KB; the block size in a 2000 TPS scenario has increased from about 130KB to around 2MB; and the TPS in the testing environment has decreased by about 40%-50%.BSC stated that the current network bottleneck mainly comes from the larger transaction data propagation, rather than the consensus protocol itself. Meanwhile, the consensus layer aggregation still maintains high efficiency, with pqSTARK achieving a signature compression ratio of about 43:1, and the additional burden on validators remains within a controllable range. The report concludes that existing technology can achieve "quantum-resistant" deployment for blockchain, but future issues related to network bandwidth and data scalability still need to be addressed.

On May 9 and 10, the Chainlink network recorded 282,170 and 264,090 unique active LINK addresses, respectively, the highest levels since September 2025. The surge in on-chain activity comes against the backdrop of several institutional-grade DeFi projects announcing their migration of cross-chain infrastructure to Chainlink CCIP. On May 7, Solv Protocol announced the completion of a security review following the April Kelp DAO vulnerability incident and decided to migrate over $700 million in tokenized Bitcoin assets (SolvBTC and xSolvBTC) from LayerZero to Chainlink CCIP.Previously, Kelp DAO had also announced the migration of its rsETH infrastructure to Chainlink CCIP. These initiatives represent a significant shift of institutional-grade DeFi infrastructure from LayerZero to the Chainlink cross-chain ecosystem. Additionally, earlier this month, data showed that whale wallets holding between 100,000 and 10 million LINK increased their holdings by 32.93 million LINK within 30 days.

According to the CatcherPredict channel, the prediction market Predict.fun has launched the prediction event "Which blockchain will Polymarket migrate to in 2026?" with a total transaction volume reaching $1.701 million.Among them, the probability of "new Polymarket chain" migration is currently reported at 67%; the probability of "not migrating in 2026" is currently reported at 26%; the probability for Arbitrum is currently reported at 2%; and the probabilities for Avalanche, Base, MegaETH, Monad, Solana, BNB Chain, and other chains are currently reported at 1%.The settlement source for this event is the official announcement of the migration from Polymarket (press release, Shayne Coplan, or official X account), non-test transactions occurring on the new chain, and the underlying L1 not being Polygon. If the migration is not completed by December 31, 2026, at 23:59 (ET), the resolution will be "not migrating in 2026."

Nic Carter, a partner at Castle Island Ventures, published a lengthy article on the X platform pointing out that the quantum computing "canary warning" mechanism cannot provide sufficient buffer time for BTC. Classical computers can currently crack approximately 117 to 130 bits of the Elliptic Curve Discrete Logarithm Problem (ECDLP), and results below this threshold are often questioned for "classical cheating" or pre-set answers, thus failing to form an effective signal.Nic Carter believes that once quantum computers truly break this classical limit, the time left for a direct attack on the 256-bit secp256k1 curve used by Bitcoin may only be a matter of months, while the migration to post-quantum (PQ) signatures after Bitcoin's completion could take years. Whether setting up quantum cracking bounty addresses or relying on Satoshi's early dormant addresses as on-chain warnings cannot guarantee sufficient early detection of risks. Therefore, the truly feasible approach is not to wait for clear warnings but to immediately begin preparations for post-quantum migration. Previously, BitMEX Research proposed a quantum freeze alternative: the "canary address" trigger mechanism.

A class action lawsuit accuses Believe founder Ben Pasternak of extracting $54 million in fees through the migration of Launchcoin. The lawsuit claims that the migration process had a two-week window, which led to the dilution of holders' tokens, and tokens that missed the deadline were permanently destroyed. Additionally, the related operations are alleged to involve insider-associated wallets.

Binance is expected to suspend token deposits and withdrawals on the Ronin network at 22:00 on May 12, 2026, to support its network migration. The network migration will take place at block height 55,577,490 and is expected to be completed by 23:00 on May 12, 2026. Users can continue to trade the tokens supported by the above network, and deposit and withdrawal services will reopen after the migration is completed.

Solana's official article on the potential impact of quantum computing on blockchain reiterates that the quantum threat is still years away, but the Solana ecosystem has already conducted thorough research and technical preparations in advance.The independent verification client development teams Anza and Firedancer (which together represent a large portion of the network's staking share) have unanimously concluded after independent research that a compact signature scheme suitable for high-throughput blockchains is needed, and they have jointly selected the Falcon scheme. Both parties have published their initial implementation code on GitHub.In addition, the Solana Winternitz Vault developed by Blueshift has been operational in the ecosystem for over two years, providing a direct quantum-resistant path. Earlier this year, Google Quantum AI listed this Vault as a leading example of forward-looking post-quantum work in its white paper.Solana's current quantum roadmap includes ongoing quantum research and evaluation of Falcon and alternative solutions; adopting post-quantum solutions for new wallets when quantum becomes a credible threat; and migrating existing wallets to the selected solution. The official statement indicates that the migration work is manageable and can be completed quickly when the time comes, with network performance expected to remain largely unaffected.

Project Eleven today awarded the Q-Day prize to researcher Giancarlo Lelli, who successfully derived a 15-digit elliptic curve private key from a public key using publicly accessible quantum hardware, marking the largest scale demonstration of its kind to date, a 512-fold increase from the 6-digit demonstration in September 2025.Lelli used a variant of Shor's algorithm for the elliptic curve discrete logarithm problem, which is the mathematical foundation of the Bitcoin signature scheme, with the awarded hardware featuring approximately 70 qubits. Currently, no known quantum computer can crack real Bitcoin wallets, and the security of Bitcoin's 256-bit elliptic curve remains far beyond current quantum capabilities. Notably, Google lowered its resource estimates for ECDLP-256 on March 31 and set a target for the migration to quantum cryptography after 2029, followed by Cloudflare, and the UK's NCSC also set migration milestones from 2028 to 2035.On-chain data shows that approximately 6.93 million BTC are at potential quantum risk due to exposed public keys. The Bitcoin community has proposed BIP 360 and BIP 361 to promote the migration to quantum-resistant output types, but the coordination challenges of a decentralized network remain the biggest hurdle.

According to CoinDesk, Blockstream CEO Adam Back stated in an interview with Bloomberg that quantum computers do not currently pose a real threat to the Bitcoin network, but the industry should start preparing immediately. He pointed out that current hardware generally lacks error correction capabilities, and quantum risks are a long-term challenge rather than an immediate crisis.Adam Back emphasized that the core issue is not reaching a consensus on when quantum computers will pose a sufficient threat, but rather providing Bitcoin holders with a time window of about ten years to migrate their keys to quantum-resistant formats.He mentioned that there is currently a research team of 20 people continuously working on related tasks, publishing papers, and conducting practical deployments, with Blockstream's Liquid network already in use as an early testing platform.Additionally, post-quantum cryptography has moved from the theoretical stage to the implementation stage, with NIST expected to finalize relevant standards by the end of 2024. The main challenge facing the industry is how to coordinate a smooth migration before the risks become urgent.

The Cosmos ecosystem wallet application Leap Wallet will cease operations on May 28, and users need to complete the migration as soon as possible. The discontinued products also include Compass Wallet (extension, iOS, Android), Leap WebApp, Swapfast, Leap Cosmos Hub validator nodes, and Leap Cosmos Snaps.

The Google Quantum AI team pointed out in their latest blog post that most blockchain technologies and cryptocurrencies rely on the vulnerable ECDLP-256 protocol. Although viable solutions such as post-quantum cryptography (PQC) already exist, implementation takes time, and the urgency for action is increasing.Google has previously set a timeline for transitioning to quantum-resistant cryptography by 2029 and is collaborating with organizations such as Coinbase, the Stanford Blockchain Research Center, and the Ethereum Foundation to advance related work.

According to Cointelegraph, Google has set 2029 as the deadline for its post-quantum cryptography migration, warning that the threat of quantum computing may arrive sooner than expected.Google stated that the rapid advancements in quantum computing hardware and quantum error correction, along with updates to the timeline for quantum computers to break current encryption standards, have heightened the urgency for action. This is the first time Google has set a timeline for the deployment of post-quantum capabilities in its products, ahead of some industry predictions for "Q-Day." Google is developing its quantum chip Willow, which has 105 qubits and is one of the most powerful quantum processors currently available.

The DeFi protocol Neutrl stated on platform X that in response to the recent DNS hijacking incident, the team has migrated the official domain to a new address and switched to a new DNS service provider. The smart contract has been unpaused and is now operating normally.Neutrl further stated that all user funds are safe, and the protocol's net asset value (NAV) and reserve assets are stored in a custodial wallet, isolated through a custodial framework and over-the-counter settlement mechanism (OES), effectively avoiding front-end and infrastructure risks.The official reminder is that users should no longer access the original domain, which will gradually be phased out. Users who have interacted with the affected domain are advised to revoke related authorizations, including Permit2 authorizations for specified malicious addresses, and to clear all unknown authorizations.

According to the official announcement from Coinbase, due to Ronin (RONIN) announcing the migration of its network to a new Ethereum L2, Coinbase will not facilitate this asset migration for its customers.Coinbase will suspend RONIN trading starting at 2 PM ET on March 30, 2026. The current order book has been switched to limit-only mode. Users must transfer RONIN to a compatible self-custody wallet before the project completes the migration; otherwise, assets left on Coinbase will be inaccessible after the migration.

Anthropic is accused of launching a prompt tool for "exporting ChatGPT memory data," helping users transfer historical memory information to its model Claude, which has drawn industry attention.According to public content, the tool allows users to export their memory data from OpenAI's ChatGPT by copying and pasting specific prompts, and then import it into Claude. Related discussions suggest that this move is seen as directly weakening the user stickiness and switching costs that ChatGPT relies on through its "memory function."Market views consider the memory mechanism as an important moat for large model products— the longer users engage, the deeper the model understands their preferences, context, and historical conversations, thereby increasing the migration costs. If third-party tools can facilitate easy data migration, it may change the current user lock-in logic of AI products.Meanwhile, reports also mentioned that Anthropic was previously restricted from use by relevant systems of the U.S. Department of Defense, but the company's popularity and attention have quickly surged, topping some application rankings.Currently, the specific compliance of the aforementioned tool and the platform's response have not been clarified. The industry generally believes that competition among large models has extended from performance comparisons to ecological and data sovereignty aspects, with user data portability potentially becoming a key variable in the next stage.
