Coinbase has formed an independent advisory board of cryptography and quantum experts to evaluate long-term risks that quantum computing could pose to Bitcoin and blockchain security.
Layer 1 protocol Saga paused its SagaEVM chain after a smart contract exploit drained nearly $7 million in USDC, which was later bridged out and converted to ether.
Blockchain security firm CertiK flagged a suspected exploit at Makina Finance that drained roughly $5 million from a stablecoin pool using a large flash loan.
A mining pool is a group of miners who combine resources to increase the chances of earning block rewards.
A public key is a cryptographic code used to receive cryptocurrency and verify digital signatures.
Hashing is the cryptographic process of converting data into a fixed-length output to secure blockchain transactions.
The scalability trilemma describes the challenge of achieving scalability, security, and decentralization simultaneously in a blockchain.
Quantum computing uses quantum mechanics to perform advanced computations and may impact blockchain security.
Proof-of-activity is a hybrid consensus method combining proof of work and proof of stake to secure blockchain networks.
Proof-of-work is a blockchain consensus system where miners solve cryptographic puzzles to validate transactions and secure the network.
