# EPF Final Dev Update > Purpose: Summarizing your activity during the program, reflect on your project and participation. ## Self-Introduction You deserve to know more than just my name. I am Godspower Eze, I am from Anambra, Nigeria and currently based in Lagos, Nigeria. And, I have been programming professionally for 3 years. ## Contributions ### Elixir Consensus Client Link - [Project Proposal](https://github.com/Godspower-Eze/cohort-four/blob/master/projects/LambdaClass-Ethereum-Elixir-Consensus-Client.md) - Added rust-elixir SSZ implementation for BeaconBlock and SignedBeaconBlock - Implemented BLS.aggregate() and BLS.aggregate_verify() - Implemented some epoch processing functions: process_eth1_data_reset and process_randao_mixes_reset - Implemented the [shuffling algorithm](https://hackmd.io/9cfa3pjvR-aCg-WJWWmbZw) - Implemented some block processing functions: process_withdrawals and process_sync_aggregate ### Cryptography Techniques Link: https://github.com/Godspower-Eze/crypto-techniques - Implemented ancients and 19th century crypto techniques like Ceasar Cipher, Simple Substitution Cipher, Polyalphabetic Cipher, One Time Pad and XOR + One Time Pad - Implemented Diffie Hallman Key Exchange and RSA - Implemented Elliptic Curve Diffie-Hellman (ECDH) and Elliptic Curve Digital Signature Algorithm (ECDSA) - Implemented Pedersen Commitments using Modular Exponentiation and Pedersen Commitments using Elliptic Curve Cryptography - Implemented Basic Polynomial Commitment using Modular Exponentiation and Basic Polynomial Commitment using Elliptic Curve Cryptography - Implemented Basic Trusted Setup using Modular Exponentiation and Basic Trusted Setup using Elliptic Curve Cryptography - And, more.. ### Verkle Trie in Nim Links: [Project Proposal](https://github.com/Godspower-Eze/cohort-four/blob/master/projects/verkle-tree-nim.md), [PR](https://github.com/mratsim/constantine/pull/273) - Worked on test generator for IPA Single-point and Multipoint Schemes ## Progress and Future Plans ### Elixir Consensus Client I will continue to contributing for the longest time and would love to see this client being used by the public. ### Cryptography Techniques This is a long-term project that would one-day be converted to a free-book on cryptography. ### Verkle Trie in Nim It's 30% done and I will continue working with them nimbus team with complete this. ## General Feedback ### Mindshift This program helped me nurture a mindset of **doing hard things**. It made me understand that working on hard things require special courage that can only be gotten by doing the hard things. ### Confidence This program help be gain confidence to many things. ## Final Words…. Grateful to God. Special thanks to Mario Havel and Josh Davis. And, to the Ethereum Foundation. I will continue DOING HARD THINGS and contributing to the ETHEREUM ECOSYSTEM. I wish everyone all the best! Thank you!
