Hudson jameson ethereum misty
I spend a lot of my time researching and consulting on decentralized systems, cryptocurrencies, blockchain systems, and InfoSec topics. I am currently splitting my time between my IoT blockchain security startup Oaken Innovations and the Ethereum Foundation. Toggle navigation Hudson Jameson. Summary I am a software developer, entrepreneur, and researcher based in Texas. Software Development Highly skilled in the Ethereum high-level contract language Solidity.
Some experience in Java and Android development. Been working with blockchain technology since Experience with many types of enterprise blockchains. Specialized in network security topics, particularly wireless security. Completed a project involving wardriving in my hometown to collect statistics on wireless network security.
College Researching and working with Bitcoin, particuarly in mining. All Ethereum clients need to upgrade; otherwise they will be stuck on an incompatible chain following the old rules. The decentralized nature of blockchain systems makes a hard fork upgrade more difficult. Hard forks in a blockchain require cooperation and communication with the community, as well as with the developers of the various Ethereum clients in order for the transition to go smoothly.
After consensus is reached on what changes should be included in a hard fork, changes to the protocol are written into the various Ethereum clients, such as geth, Parity, and ethereumJ. The protocol changes are activated at a specific block number. Any nodes that have not been upgraded to the new ruleset will be abandoned on the old chain where the previous rules continue to exist. Since September 18th UTC , the Ethereum network has been under attack by a person or group resulting in large delays before transactions were processed.
The network is currently filled with pending transactions which is causing users delays in processing their transactions. You can think of this as a denial of service DoS attack on the Ethereum blockchain.
Every operation that an Ethereum contract performs on the network is given a price or gas fee. Using the ADD operation is less computationally expensive than performing a complex operation such as hashing a number using SHA The attacker performed a DoS attack by repeatedly calling certain operation codes opcodes in their smart contracts that are computationally difficult for clients to process, but very cheap to add to the network.
In order to prevent the attacker s from continuing to flood the network with low-priced contracts with high computational cost, we are raising the price of certain operations. The two hard forks each address different problems that have arisen from the attacks.
