 - ***zkstark ultra-light node:*** To optimize the light nodes mentioned above, zkstark technology can be used to realize the ultra-light nodes of BTC.
 
 ### Four advantages compared to other layer2/cross-chain bridges （Take [tBTC](https://www.thresholdusd.org/en/) as an example）
-- 1, ***No centralized initial setup required.*** There is no need to use sharding private keys to implement distributed threshold signatures, which avoids the security problem of private key leakage caused by sharding private keys.  Directly use BTC's native threshold signature scheme: [MuSig2](https://eprint.iacr.org/2020/1261).
+- 1, ***No centralized initial setup is required.*** There is no need to use sharding private keys to implement distributed threshold signatures, which avoids the security problem of private key leakage caused by sharding private keys.  Directly use BTC's native threshold signature scheme: [MuSig2](https://eprint.iacr.org/2020/1261).
 - 2, ***Distributed network on the chain, more decentralized.*** The validators of the distributed threshold network are all block verification nodes on the chain, and the network on the chain increases trust. It avoids the opaque and easy-to-operate defects of the distributed network under the chain.
 - 3, ***No permission required, just trust the code.*** The BTC to Layer2 network uses BTC light nodes. The blockchain logic of fully trusting the code avoids the centralized fraud problem caused by the submission of data oracle to the distributed network under the chain.
 - 4, ***Distributed network communication with complete privacy.*** The [Signal protocol](https://en.wikipedia.org/wiki/Signal_Protocol) is used to complete the communication problem of the BTC taproot threshold signature. Solve the privacy communication problem of distributed network. Avoid the risks of data leakage, collusion or external attacks when threshold signatures appear
