FIELD NOTE 001 / DIGITAL SYSTEMS
LEG Ehitus OÜ helps small teams make sense of blockchain technology, shape digital protocols, explain technical products clearly, and turn a tangled idea into a workable company plan.
Start with the machinery: shared state, transactions, nodes, consensus, smart contracts, and the places where a product touches the network.
Understand the roles around Bitcoin: nodes, wallets, the mempool, block production, network fees, and the practical boundaries a product team should know.
Learn how ledgers, accounts, transactions, validators, and network rules fit together so your team can discuss the XRP Ledger with precision.
Map validator duties, consensus clients, execution clients, uptime, slashing concepts, and the operational questions behind Ethereum staking infrastructure.
Separate the label from the system. We explain how digitally represented items, rights, records, and network-native units differ by design and context.
Learn to read addresses, blocks, transactions, contracts, and validator information without treating an explorer screen like a mystery box.

WHEN THE TEAM IS STUCK
We can run a team consultation when you need help shaping an app, a digital company, a protocol concept, or the marketing around it. You do not need a polished brief—come with the questions your team is circling around.
