[ad_1] I’m joining Ethereum as a formal verification engineer. My reasoning: formal verification makes sense as a profession only in a rare situation where the verification target follows short, simple rules (EVM); the target carries lots of value (Eth and other tokens); the target is tricky enough to get right […]

[ad_1] As a global public resource, technology must remain open, accessible, and dedicated to promoting the greater good. The Next Billion Fellowship Program is a testament to this vision, seeking to capture stories of communities whose lives are changing for the better. Today, we are proud to introduce seven individuals […]

[ad_1] Amit Kumar New York University Proof Carrying Data from folding GKR with protostar Current Interactive Verifiable Computation (IVC) schemes face challenges with the Witness-Multi-Scalar Multiplication (Witness-MSM) barrier, limiting efficiency. We propose leveraging the Goldwasser-Kalai-Rothblum (GKR) accumulation scheme to significantly reduce the witness size, overcoming these limitations. Utilizing the Protostar […]

[ad_1] Security Alert Affected configurations: Geth Likelihood: High Severity: High Summary: geth nodes running out of memory and crashing on block https://etherchain.org/block/2283416 Details: TBD Solution: [Geth 1.4.12](http… [ad_2] Source link

[ad_1] URGENT ALL MINERS: The network is under attack. The attack is a computational DDoS, ie. miners and nodes need to spend a very long time processing some blocks. This is due to the EXTCODESIZE opcode, which has a fairly low gasprice but which requires nodes to read state information […]

[ad_1] Today the network was attacked by a transaction spam attack that repeatedly called the EXTCODESIZE opcode (see trace sample here), thereby creating blocks that take up to ~20-60 seconds to validate due to the ~50,000 disk fetches needed to process the transaction. The result of this was a ~2-3x […]

[ad_1] During the last couple of weeks, the Ethereum network has been the target of a sustained attack. The attacker(s) have been very crafty in locating vulnerabilities in the client implementations as well as the protocol specification. While the recent patches have led to an overall increased resiliency in the […]

[ad_1] The Ethereum network will be undergoing a hard fork at block number 2463000, which will likely occur between 12:00 and 13:00 UTC on Tuesday, October 18, 2016. A countdown timer can be seen at https://fork.codetract.io/. As a user, what do I need to do? Download the latest version of […]

[ad_1] Mist leaks some low level APIs, which Dapps could use to gain access to the computer’s file system and read/delete files. This would only affect you if you navigate to an untrusted Dapp that knows about these vulnerabilities and specifically tries to attack users. Upgrading Mist is highly recommended to prevent […]

[ad_1] One of the important indicators of how much load the Ethereum blockchain can safely handle is how the uncle rate responds to the gas usage of a transaction. In all blockchains of the Satoshian proof-of-work variety, any block that is published has the risk of howbecoming a “stale”, ie. […]
