You will write and review code in GoLang, with Typescript and Python playing important parts in our product as well. You are fluent with Git, are accustomed to remote work, and have worked on small teams in a startup environment in the past.


About Vulcanize


Vulcanize, Inc. are blockchain and IPLD experts with many years of experience in Ethereum and CosmosSDK, as well as a solid understanding of blockchain and database fundamentals.


The Vulcanize team works on Laconic, a collection of software that empowers Web3 developers to access multi-chain data in a way that uniquely preserves the verifiability of the data they extract. This service is powered by their open source IPLD-based Postgres database. It has a full index of Ethereum chain data and they are in the process of adding additional chains. The Laconic stack relies on IPLD, leverages IPFS, and intends to use Filecoin for archival storage. The repositories that make up the Laconic Stack are listed in the relevant repos below.


The Laconic product suite also includes Watchers, which auto-generate code from Solidity source, capable of reading and transforming activity from smart contracts into IPLD blocks stored and indexed in a relational database. Using the Laconic techniques, Vulcanize was able to accelerate a number of services, in particular, serving The Graph subgraphs and RPC endpoint queries. The Laconic work originated with VulcanizeDB, a technology conceived while Vulcanize was working with MakerDAO in 2017.


Since 2016, Vulcanize has been awarded a plethora of prestigious grants and contracts. They were core contributors to Ethereum, IPLD / IPFS, and CosmosSDK. Vulcanize received a grant from the Ethereum Foundation for EIP-1559.  Vulcanize was twice appointed by the Interchain Foundation for Core Contribution to the Cosmos SDK, where they worked on SMT and State Streaming (ADRs 38 and 40). The Interchain Foundation also awarded Vulcanize a grant to work  on Tendermint-Cosmos IPFS integration and to develop a Postgres-IPFS caching layer. This work was never completed, but produced IPLD schemas for the Tendermint and Cosmos data structures, as well as a Golang implementation of IPLD codecs for these objects, and a proposed scheme for providing generic IPLD support for any CosmosSDK chain. Vulcanize President Rick Dudley also served on the TAC (Technical Advisory Committee) for Interhain Foundation for several terms. 


Vulcanize also received a grant from MolochDAO to build an IPLD-based Ethereum block explorer.


Vulcanize has received prior large grants from Protocol Labs for their “Ethereum as IPLD” work. This work produced IPLD schemas for the Ethereum data structures as well as Typescript and Golang implementations of IPLD codecs for these objects.
