In short, it ensures that the transactions contained in blocks follow the rules defined in the Ethereum protocol and state transitions (changes in the distributed database) are executed rightfully. It also specifies a lot of other things such as the inflation rate (block reward) that goes to miners. How they are encoded into the clients is left to the teams. The Ethereum protocol specifications are high-level rules which coordinate things like the way transactions are broadcasted from end-users into the mempool (where they are picked up by miners) and how miners broadcast their block to the rest of the network once the cryptographic puzzle (a.k.a proof-of-work) has been solved. ![]() They differ mostly on small technical subtleties that matter to developers such as the programming language they are written in, the amount of developer support they have, or the open-source licenses they employ. If one client software were to fail due to a flaw in the software, the network could still continue to run normally as there are a sufficient number of nodes running on other clients.Įach client is maintained by a different team but all follow the same Ethereum protocol specifications. Client diversity has the benefit of making the network more resilient. ![]() This is in stark contrast to Bitcoin where only one software client exists, namely Bitcoin Core. The most popular one is Geth but other ones like OpenEthereum, Besu or Nethermind are also quite popular. To be clear there is not just one software client but actually 4-5 different ones. This node software implements the rules of the Ethereum protocol. To participate in the Ethereum network you need to run a specific type of software called node software or client. How are the rules of the network enforced? These rules are determined by the system and close to impossible to change. We can’t decide not to pay taxes or to take drugs in public. This option doesn’t exist in the real world where we can’t single-handedly exit the system or change its rules. Perhaps the most important difference to the social contract we abide by in the real world, is that in a decentralized network every participant has the option to “rage quit”, to leave the network if they’re not happy with the latest changes and continue with their own alternate version of the network. The truth is decentralized networks have governance processes and every aspect of a network can theoretically change. Listen to our 1 hr podcast with Tim Beiko (Ethereum Core Developer) on Ethereum's governance for a deep dive How do we know that the supply cap, according to which only 21m bitcoins can ever come into existence, cannot be changed in a few years? Why are changes being made to the economic policy of Ethereum and most importantly who decides these changes? In simple terms how does decentralized governance work? One of the concepts that is perhaps hardest to grasp for newcomers to the crypto space is the fact that networks like Bitcoin or Ethereum can be decentralized while still being able to evolve and develop. ![]()
