BerTech Is Building on Hedera

BerTech is building LedgerSign on Hedera — and we want to tell you why. The decision to build on Hedera instead of a traditional blockchain reflects everything we have learned about what enterprise-grade infrastructure actually requires: instant finality, predictable low fees, energy efficiency, and a governance model built for regulated industries. This article explains the technology, why it matters, and what it means for professional services firms that need to trust their document signing infrastructure.

What Is Hedera?

Hedera is an enterprise-grade public network built on hashgraph technology — a fundamentally different approach to distributed consensus than traditional blockchain. Where blockchain processes transactions in sequential blocks, hashgraph uses a directed acyclic graph (DAG) structure that allows transactions to be processed in parallel, achieving speeds and efficiency that conventional blockchains cannot match.

The practical advantages for enterprise use cases are significant:

• Instant finality: Transactions on Hedera reach finality in 3–5 seconds with absolute certainty. There are no forks, no reorganizations, no probabilistic finality. When a document signature is recorded on Hedera, it is recorded permanently and immediately — no waiting for block confirmations.
• High throughput: Hedera processes over 10,000 transactions per second on the public network, making it viable for high-volume enterprise workflows. Traditional blockchains like Ethereum process 15–30 transactions per second.
• Low, predictable fees: Transaction fees on Hedera are fixed in USD terms and denominated in fractions of a cent. Firms can plan infrastructure costs precisely without exposure to volatile gas price spikes.
• Energy efficiency: Hedera is certified carbon-negative. It uses a fraction of the energy consumed by proof-of-work blockchains. For organizations with sustainability commitments, this matters.
• Enterprise governance: Hedera is governed by a council of global organizations — including Google, IBM, Boeing, Deutsche Telekom, and others — providing a stable, accountable governance structure that enterprises can rely on for long-term infrastructure decisions.

What Is Blockchain?

Blockchain is a distributed ledger — a record of transactions maintained simultaneously across many computers rather than in a single central database. This architecture has one defining property: immutability. Once data is written to a blockchain, it cannot be altered or deleted without invalidating the entire chain of records that follows it.

For document signing, immutability is the core value proposition. When a contract is signed and the signature event is recorded on a blockchain, you have a cryptographic proof of what was signed, by whom, and when — a proof that cannot be tampered with, that does not depend on any single organization's server staying online, and that can be verified independently by any party without needing to trust the platform that recorded it.

This removes the central authority problem that has always existed in digital document signing. Traditional e-signature platforms — however reputable — are trusted intermediaries. Their records are authoritative because you trust the company. Blockchain-based signing is authoritative because the cryptographic record exists on a public network that no single entity controls.

Why BerTech Chose Hedera for LedgerSign

When we evaluated the infrastructure layer for LedgerSign, the requirements were clear: a platform that could handle high transaction volumes at low cost, with instant finality, strong regulatory standing, and an energy footprint consistent with enterprise sustainability standards. Hedera met every requirement. Traditional blockchains did not.

• For document signing workflows, instant finality is non-negotiable. A signing event that takes minutes to confirm creates workflow friction and legal ambiguity. Hedera's 3–5 second finality means signature recording is effectively synchronous from a user perspective.
• For professional services firms signing thousands of documents per month, fee predictability matters. A platform where transaction costs can spike by 10x during network congestion is not viable enterprise infrastructure. Hedera's fixed-fee model enables precise cost planning.
• For regulated industries — finance, law, real estate — the governance model of the underlying network matters. Hedera's enterprise council governance provides the institutional accountability that regulated firms and their auditors require.
• For organizations with ESG commitments, energy consumption is increasingly a procurement consideration. Hedera's carbon-negative status means choosing LedgerSign does not conflict with sustainability goals.

What LedgerSign Does on Hedera

LedgerSign is a blockchain-native document signing platform built for professional services firms. It uses Hedera's Token Service and Consensus Service to record cryptographic proofs of every signing event on the public Hedera network. Here is what that delivers in practice:

Tamper-proof verification

Every signed document generates a unique cryptographic hash — a digital fingerprint — that is recorded on Hedera at the moment of signing. If any byte of the document changes after signing, the hash no longer matches the on-chain record. Tampering is immediately detectable, verifiable by anyone, without needing to contact LedgerSign or BerTech.

Multi-party signing with immutable sequencing

For documents requiring multiple signatories — commercial leases, loan agreements, partnership contracts — LedgerSign records each signing event on Hedera in sequence. The on-chain record shows not just that a document was signed, but who signed, in what order, and at what timestamp. This sequencing is cryptographically enforced, not just database-recorded.

Audit trails that outlast the platform

Traditional e-signature audit trails live in the platform's database. If the vendor is acquired, goes offline, or changes their data retention policy, your audit trail is at risk. LedgerSign's audit records live on the Hedera public network — a decentralized infrastructure that no single company controls. Your signing history remains verifiable regardless of what happens to any individual vendor.

Blockchain-based signing is not just a technology upgrade over traditional e-signatures. It is a different trust model — one that does not require trusting any single organization to maintain honest records.

What This Means for Professional Services Firms

The professional services industries that rely most heavily on document signing — commercial real estate, law, finance, consulting — are also the industries facing the greatest pressure around document authenticity, audit trail requirements, and regulatory scrutiny. LedgerSign on Hedera addresses all three:

• Document authenticity: Blockchain verification provides a level of cryptographic certainty that no database-backed e-signature platform can match. For high-value transactions — commercial leases, M&A agreements, loan documents — that certainty has real legal and operational value.
• Audit trail requirements: Regulators, lenders, and counterparties increasingly require demonstrable audit trails for document execution. An immutable on-chain record satisfies these requirements in a way that is independently verifiable and cannot be altered after the fact.
• Regulatory alignment: As digital asset and blockchain regulations mature — including the EU's MiCA regulation and evolving US frameworks — having signing infrastructure built on a regulated, enterprise-governed network like Hedera positions your firm ahead of compliance requirements rather than behind them.

Building Together

LedgerSign is BerTech's first production deployment on Hedera, but it will not be the last. The same infrastructure that powers blockchain document signing supports tokenization of real-world assets, on-chain identity verification, smart contract-based escrow, and digital asset management — all use cases we are actively developing for professional services clients.

If your firm has projects you want to move to blockchain — document workflows, asset tokenization, identity verification, or anything else — we want to hear about them. The technology is ready. The infrastructure is enterprise-grade. The question is what you want to build.
